On October 31, 2018, the SEC adopted final rules effecting a complete overhaul of the technical disclosure requirements applicable to companies engaged in material mining operations, including royalty companies.  Upon effectiveness, the new rules will replace the SEC’s decades-old guidelines, set forth in Industry Guide 7 (Guide 7), with new subpart 1300 of Regulation S-K, based on the Committee for Mineral Reserves International Reporting Standards (CRIRSCO).  All SEC reporting companies, other than those who file under the Canada-U.S. Multijurisdictional Disclosure System (MJDS), will be required to comply with the new rules for their first fiscal year beginning on or after January 1, 2021.  Foreign private issuers who file on Forms 20-F, F-1, F-3 or F-4 will no longer be permitted to include non-compliant disclosures in such filings.  The final rules can be found here.

In this corporate update, we provide a discussion of the final rules in question and answer format.  To move forward to a particular question, you may click on one of the links below:

Why has the SEC adopted new rules for mining companies?

The SEC’s guidelines for mining disclosure, currently set forth in Industry Guide 7 (Guide 7), have not been updated for more than 30 years.  During this period, mining has become an increasingly globalized industry and several foreign countries have adopted mining disclosure standards based on the Committee for Mineral Reserves International Reporting Standards (CRIRSCO), which significantly differ from Guide 7.  For example, unlike Guide 7, CRIRSCO standards:

  • Require companies to disclose material mineral resources;
  • Require that any public report about a company’s exploration results, mineral resources and mineral reserves be prepared by a “competent or qualified person”; and
  • Permit disclosure of mineral reserves to be based on a preliminary feasibility (pre-feasibility) study or a final feasibility study.

Because of the widespread adoption of the CRIRSCO standards1, industry participants requested revisions to Guide 7, urging the SEC to align its mining disclosure rules with the CRIRSCO-based codes.  The SEC’s replacement of Guide 7 with a CRIRSCO-based code takes into account these global developments and industry participants’ concerns.

When will the new rules become effective?

The new rules will become effective for an SEC registrant’s first fiscal year beginning on or after January 1, 2021.  As an example of what this means, the SEC has stated that a registrant with a December 31 fiscal year end will be required to comply with the final rules when filing an applicable registration statement2 on or after January 1, 2021, and when filing its SEC annual report for the fiscal year ended December 31, 2021.  For registrants filing registration statements in 2021, this has the effect of accelerating public reporting under the new rules.

Once the SEC has completed EDGAR reprogramming made necessary by the final rules, the SEC will permit registrants to voluntarily comply with the new mining property disclosure rules as of an earlier date, as long as in doing so, they comply with all of the new requirements.  Until then, registrants should continue to comply with Guide 7 for their mining property disclosures.

Return to Top

What types of companies will be subject to the new rules?

The final rules will apply to an SEC registrant that has mining operations that are material to its business or financial condition.  

Mining operations is defined under the final rules as including operations on all mining properties that a registrant:

  • Owns or in which it has, or it is probable that it will have, a direct or indirect economic interest;
  • Operates, or it is probable that it will operate, under a lease or other legal agreement that grants the registrant ownership or similar rights that authorize it, as principal, to sell or otherwise dispose of the mineral; or
  • Has, or it is probable that it will have, an associated royalty or similar right.

The SEC has not modified its definition of materiality in the new rules. Information is material if there is a substantial likelihood that a reasonable investor would attach importance to such information in determining whether to buy or sell the securities registered.

Because the new rules define mining operations to include both direct and indirect economic interests, and because the standard for disclosure is materiality, companies that hold royalties, streaming agreements or other economic interests with respect to mining properties, as well as companies that invest in mining companies, will be subject to the new rules if such interests are material to the registrant’s business or financial condition.

Will foreign private issuers be subject to the new rules?

Yes.  Foreign private issuers that file annual reports or registration statements with the SEC on Forms 20-F, F-1, F-3 or F-4, that voluntarily file on U.S. domestic reporting forms or that prepare offering circulars on Form 1-A under Regulation A+ will be required to comply with the new rules.

Canadian issuers that file annual reports or registration statements with the SEC under the Multijurisdictional Disclosure System (MJDS), including Forms 40-F, F-10, F-7, F-8 and F-80, will not be required to comply with the new rules.

What are the main differences between the SEC’s Industry Guide 7 and the new rules?

The chart in Appendix A provides an overview of the main differences between existing Guide 7 and related SEC guidance, and the new rules.

What are the main differences between the SEC’s initial proposal in 2016 and the new rules?

The SEC first proposed an overhaul of the disclosure requirements for mining companies, and solicited comments on its proposed rules, in 2016.  Many industry organizations, companies, and law firms that commented on the proposals were supportive of the idea of modernization, but felt that the SEC’s proposals were too prescriptive and varied in too many ways from CRIRSCO standards, thereby imposing an administrative burden on companies, especially those reporting in more than one jurisdiction.

In response to these comments, the SEC’s final rules incorporated a number of changes, many of which were intended to more closely align the SEC’s mineral property disclosure requirements with CRIRSCO standards, and thereby help decrease the compliance burden and costs on registrants that are subject to additional CRIRSCO-based codes.  For example, as compared to the 2016 proposals, the final rules:

  • eliminate the prohibition on estimating mineral resources and mineral reserves using a commodity price that is greater than the 24-month historical average;
  • allow mineral reserves to be declared based on a pre-feasibility study, even in high-risk situations;
  • allow mineral reserves to include diluting materials and allowances for losses;
  • permit inferred mineral resources to be included in the economic analysis that is included in an initial assessment (the equivalent to a preliminary economic assessment under Canada’s NI 43-101);
  • eliminate the requirement for a technical report summary in order to disclose material exploration results;
  • permit mineral resources and reserves to be disclosed at any specific point of reference selected by the qualified person, rather than three (in situ, plant or mill feed, and saleable product);
  • permit the use of non-compliant, historic estimates of mineral resources or mineral reserves in SEC filings pertaining to mergers, acquisitions and business combinations, subject to certain conditions;
  • permit registrants holding royalty or similar interests to omit information to which they lack access and which they cannot obtain without incurring an unreasonable burden or expense;
  • will not apply to geothermal fields;
  • permit the disclosure of exploration targets;
  • eliminate many of the quantitative thresholds in the proposed rules, in favor of more qualitative standards;
  • reduce the number of required tables, and the amount of information required to be included in tables;
  • clarify that technical report summaries may be authored by more than one qualified person; and
  • allow a qualified person to rely on certain information provided by the registrant.

In addition, the final rules clarify that when a qualified person is not an employee of the registrant and is not otherwise affiliated with the registrant, the technical report summary and any required expert consent may be signed by the third-party firm that employs the individual qualified person, without naming the individual.

Return to Top

Are the SEC’s new rules the same as the standards under Canada’s National Instrument 43-101 (NI 43-101) or other CRIRSCO-based codes?

No.  While the SEC’s new rules are intended to be substantially similar to those of other CRIRSCO-based codes, they are not identical to any single CRIRSCO-based code.  Some differences relate to terminology.  For example, the SEC’s new rules use the term “technical report summary” instead of NI 43-101’s “technical report”, and the term “initial assessment” instead of NI 43-101’s “preliminary economic assessment”.  Other differences relate to substantive requirements, and are in some cases subtle.  SEC registrants that are subject to other CRIRSCO-based codes should compare such codes to the SEC’s new rules and determine whether the differences have any material implications for the registrant.

Return to Top

How do the new rules affect the characterization of a mining company and its properties as being in the exploration, development or production stage?

The new rules introduce a materiality threshold for being considered a development or production stage issuer.  Under the new rules, a registrant is defined as:

  • An exploration stage issuer if it has no material property with mineral reserves;
  • A development stage issuer if it is engaged in the preparation of mineral reserves for extraction on at least one material property; or
  • A production stage issuer if it is engaged in material extraction of mineral reserves on at least one material property.

The new rules also clarify how individual properties of a mining company should be described.  Under the new rules, an individual property is defined as being:

  • An exploration stage property if it has no mineral reserves disclosed;
  • A development stage property if it has mineral reserves disclosed, but with no material extraction; and
  • A production stage property if it has material extraction of mineral reserves.

It should be noted that both Guide 7 and the new rules require a registrant to have disclosed mineral reserves in order to describe itself as being either a development or production stage company, regardless of whether the registrant is actively constructing a mine or operating a producing mine. Guide 7 does not discuss the characterization of individual properties, or distinguish between properties of a registrant that are at different stages of development.

Return to Top

Who is a qualified person?

Consistent with CRIRSCO-based mining codes, the new rules would introduce the concept of a qualified person, a mineral industry professional meeting certain criteria, whose expertise must be utilized in preparing certain mining disclosures.

In the final rules, a qualified person is defined as an individual who is:

  • A mineral industry professional with at least five years of relevant experience in the type of mineralization and type of deposit under consideration and in the specific type of activity that person is undertaking on behalf of the registrant; and
  • An eligible member or licensee in good standing of a recognized professional organization at the time the technical report is prepared.

To be a recognized professional organization, an organization must:

  • Be either:
    • An organization recognized within the mining industry as a reputable professional association, or
    • A board authorized by U.S. federal, state or foreign statute to regulate professionals in the mining, geoscience or related field;
  • Admit eligible members primarily on the basis of their academic qualifications and experience;
  • Establish and require compliance with professional standards of competence and ethics;
  • Require or encourage continuing professional development;
  • Have and apply disciplinary powers, including the power to suspend or expel a member regardless of where the member practices or resides; and
  • Provide a public list of members in good standing.

The SEC has stated that it does not intend to publish and maintain a list of recognized professional organizations.

A person is not required to be independent of the registrant in order to be a qualified person.  Therefore, an employee of the registrant that satisfies the requisite criteria of experience and membership in a recognized professional organization could serve as the registrant’s qualified person.

Return to Top

What role does a qualified person serve under the new rules?

A registrant’s disclosure of exploration results, mineral resources and mineral reserves, as required by the new rules, must be based on and accurately reflect information and supporting documentation prepared by a qualified person. The registrant is responsible for determining that the person meets the requirements of a qualified person, and that the disclosure in the registrant’s filing accurately reflects the information provided by the qualified person.

With respect to any property containing mineral resources or mineral reserves that is material to the registrant’s business or financial condition, the registrant must obtain a dated and signed technical report summary from the qualified person, which identifies and summarizes the information reviewed and conclusions reached by the qualified person about the registrant’s mineral resources and mineral reserves results determined to be on such property.  A registrant may, but is not required to, obtain a dated and signed technical report summary from a qualified person relating to exploration results on a property prior to the declaration of mineral resources or mineral reserves.

When a qualified person is not an employee of the registrant and is not otherwise affiliated with the registrant, the technical report summary and any required expert consent may, but is not required to be, be signed by the third-party firm that employs the individual qualified person, without naming the individual.

Return to Top

Who has to sign consents and when must they be filed?

Written consents of a qualified person are required to the use of the qualified person’s name, or any quotation from, or summarization of, the technical report summary in the relevant registration statement or report, and to the filing of the technical report summary as an exhibit to the registration statement or report.  

The rules provide that a third-party firm comprising mining experts, such as professional geologists or mining engineers, may sign the technical report summary instead of, and without naming, its employee, or other affiliated person who prepared the summary.  If a third-party firm has signed the technical report summary, the firm must provide the written consent.  So, if an individual qualified person is employed by a third-party firm, that firm may sign the technical report summary and provide the written consent required for an expert under the Securities Act.  However, if a qualified person is an employee of, or affiliated with, the issuer, the qualified person must provide the written consent on an individual basis.

The written consent must be filed as an exhibit to a Securities Act registration statement.  However, for periodic reports, the registrant is not required to file the written consent obtained from the qualified person, but should retain the written consent for as long as it is relying on the qualified person’s information and supporting documentation for its current estimates regarding mineral resources, mineral reserves, or exploration results.

Return to Top

In what circumstances may a qualified person rely on, or disclaim, information provided by third parties?

The new rules permit a qualified person, in preparing its findings and conclusions, to rely on information provided by the registrant regarding the following aspects of modifying factors:

    • macroeconomic trends, data, and assumptions, and interest rates;
    • marketing information and plans within the control of the registrant;
    • legal matters outside the expertise of the qualified person, such as statutory and regulatory interpretations affecting the mine plan;
    • environmental matters outside the expertise of the qualified person;
    • accommodations the registrant commits or plans to provide to local individuals or groups in connection with its mine plans; and
    • governmental factors outside the expertise of the qualified person.

Any such reliance must be disclosed in the applicable technical report summary, and accompanied by additional information as described in Appendix B.

A technical report summary may be prepared by more than one qualified person, with the summary clearly delineating the section or sections of the summary prepared by each qualified person.

A qualified person may also include in the technical report summary information provided by a third-party specialist who is not a qualified person, such as an attorney, appraiser, and economic or environmental consultant, upon which the qualified person has relied in preparing the technical report summary.  However, the qualified person may not disclaim responsibility for any information or documentation prepared by such a third-party specialist.

What are mineral resources and how are they calculated?

Unlike Guide 7, the new rules both recognize and require the disclosure of mineral resources.  The rules define a mineral resource as a concentration or occurrence of material of economic interest in or on the Earth’s crust in such form, grade or quality, and quantity, that there are reasonable prospects for economic extraction.  Material of economic interest includes mineralization, including dumps and tailings, mineral brines, and other resources extracted on or within the Earth’s crust, but does not include oil and gas resources as defined in Regulation S-X, gases (e.g., helium and carbon dioxide), geothermal fields or water.

An instruction to the rules clarifies that a mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable.  The rules set forth a definition of cut-off grade and provide for requirements that a qualified person must satisfy in determining the existence of a mineral resource.  These include the evaluation of modifying factors, which is the term used in the new rules to describe factors that affect the economic prospects of a deposit.  Modifying factors include, but are not restricted to: mining; processing; metallurgical; infrastructure; economic; marketing; legal; environmental compliance; plans, negotiations or agreements with local individuals or groups; and governmental factors.  The number, type and specific characteristics of the modifying factors applied will necessarily be a function of and depend upon the mineral, mine, property, or project.

When mineral resources are determined, a qualified person must subdivide mineral resources, in order of increasing geological confidence, into inferred, indicated and measured mineral resources.

Return to Top

What are the differences between inferred, indicated and measured mineral resources?

The new rules create three different categories of mineral resources based on the level of geological confidence that the mineral resource exists.

An inferred mineral resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling, which means evidence that is only sufficient to establish that geological and grade or quality continuity is more likely than not.  An inferred mineral resource has the lowest level of geological confidence of all mineral resources, which in the SEC’s view prevents the application of the modifying factors in a manner useful for evaluation of economic viability.  

An indicated mineral resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling, which means evidence that is sufficient to establish geological and grade or quality continuity with reasonable certainty.  The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.  An indicated mineral resource has a lower level of confidence than that applying to a measured mineral resource and may only be converted to a probable mineral reserve.

A measured mineral resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling, which means evidence that is sufficient to test and confirm geological and grade or quality continuity.  A measured mineral resource has a higher level of confidence than that applying to either an indicated mineral resource or an inferred mineral resource.  It may be converted to a proven mineral reserve or to a probable mineral reserve.

Return to Top

How will the new rules affect the definitions of mineral reserves, probable mineral reserves and proven mineral reserves?

Under existing Guide 7, a reserve is that part of a mineral deposit which could be economically and legally extracted or produced at the time of the reserve determination.  Reserves are to be identified as probable or proven based on the mineralization’s level of certainty.  The SEC’s staff has provided guidance that a final feasibility study is required to support the establishment of reserves and that the commodity prices used in establishing a Guide 7 reserve should not exceed the 3-year trailing average price of such commodity.

The new rules retain the categories of probable and proven reserves, but replace the existing Guide 7 definitions with new definitions, permit mineral reserves to be established on the basis of either a preliminary feasibility (pre-feasibility) study or a final feasibility study and replace the 3-year trailing average price limitation with a requirement that the commodity prices used in calculating mineral reserves provide a reasonable basis for establishing that the project is economically viable.

Under the new rules, a mineral reserve is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted.

The determination that part of a measured or indicated mineral resource is economically mineable must be based on a pre-feasibility or feasibility study conducted by a qualified person applying the modifying factors to indicated or measured mineral resources.  Such study must demonstrate that, at the time of reporting, extraction of the mineral reserve is economically viable under reasonable investment and market assumptions.  The study must establish a life of mine plan that is technically achievable and economically viable, which will be the basis of determining the mineral reserve.

A probable mineral reserve is the economically mineable part of an indicated and, in some cases, a measured mineral resource.  For a probable mineral reserve, the qualified person’s confidence in the results obtained from the application of the modifying factors and in the estimates of tonnage and grade or quality is lower than what is sufficient for a classification as a proven mineral reserve, but is still sufficient to demonstrate that, at the time of reporting, extraction of the mineral reserve is economically viable under reasonable investment and market assumptions. 

A proven mineral reserve is the economically mineable part of a measured mineral resource.  For a proven mineral reserve, the qualified person has a high degree of confidence in the results obtained from the application of the modifying factors and in the estimates of tonnage and grade or quality.

For purposes of estimating mineral reserves, the modifying factors are the same factors as are used in estimating mineral resources, as applied to determine the economic viability of mineral reserves.  A qualified person must apply and evaluate modifying factors to convert measured and indicated mineral resources to proven and probable mineral reserves.

Return to Top

What are the different types of technical report summary?

The new rules describe four types of technical report summary:

  • A technical report summary that discloses exploration results;
  • An initial assessment, which is required to establish mineral resources;
  • A preliminary feasibility study (pre-feasibility study), which is required to establish mineral reserves; and
  • A feasibility study or final feasibility study.

Under the new rules, exploration results are defined as data and information generated by mineral exploration programs (i.e., programs consisting of sampling, drilling, trenching, analytical testing, assaying, and other similar activities undertaken to locate, investigate, define or delineate a mineral prospect or mineral deposit) that are not part of a disclosure of mineral resources or reserves.  

An initial assessment is a preliminary technical and economic study of the economic potential of all or parts of mineralization to support the disclosure of mineral resources.  The initial assessment must be prepared by a qualified person and must include appropriate assessments of reasonably assumed modifying factors, together with any other relevant operational factors that are necessary to demonstrate, at the time of reporting, that there are reasonable prospects for economic extraction.  An initial assessment is required for disclosure of mineral resources but cannot be used as the basis for disclosure of mineral reserves.

A preliminary feasibility study (pre-feasibility study) is a comprehensive study of a range of options for the technical and economic viability of a mineral project that has advanced to a stage where a qualified person has determined (in the case of underground mining) a preferred mining method, or (in the case of surface mining) a pit configuration, and in all cases has determined an effective method of mineral processing and an effective plan to sell the product.  A pre-feasibility study includes a financial analysis based on reasonable assumptions, based on appropriate testing, about the modifying factors and the evaluation of any other relevant factors that are sufficient for a qualified person to determine if all or part of the indicated and measured mineral resources may be converted to mineral reserves at the time of reporting. The financial analysis must have the level of detail necessary to demonstrate, at the time of reporting, that extraction is economically viable.  A pre-feasibility study is less comprehensive and results in a lower confidence level than a feasibility study. A pre-feasibility study is more comprehensive and results in a higher confidence level than an initial assessment.

A feasibility study is a comprehensive technical and economic study of the selected development option for a mineral project, which includes detailed assessments of all applicable modifying factors, as defined by this section, together with any other relevant operational factors, and detailed financial analysis that are necessary to demonstrate, at the time of reporting, that extraction is economically viable.  The results of the study may serve as the basis for a final decision by a proponent or financial institution to proceed with, or finance, the development of the project.  A feasibility study is more comprehensive, and with a higher degree of accuracy, than a pre-feasibility study.  It must contain mining, infrastructure, and process designs completed with sufficient rigor to serve as the basis for an investment decision or to support project financing.  The confidence level in the results of a feasibility study is higher than that with a pre-feasibility study.  Terms such as full, final, comprehensive, bankable, or definitive feasibility study are equivalent to a feasibility study.

Return to Top

When must a technical report summary initially be filed?

The new rules require that a registrant file a technical report summary authored by a qualified person as an exhibit to its SEC annual report or applicable registration statement when the registrant is disclosing in such report or registration statement, for the first time, mineral resources or mineral reserves for a property that is material to the registrant’s business or financial condition.  A registrant also may, but is not required to, file a technical report summary with respect to exploration results.

Certain exceptions apply to a registrant that only holds a royalty, streaming or other similar right with respect to a property.  Such a registrant is not required to file a technical report summary for a property that is covered by a current technical report summary filed by the producing mine registrant.  In that situation, the registrant holding the royalty, streaming or other similar right should refer to the producing registrant’s previously filed technical report summary. Such a reference will not be deemed to incorporate the report by reference, absent an express statement to such effect.

If such a report has not been filed, the registrant holding the royalty, streaming or other similar right will be required to file a technical report summary for the underlying property unless the registrant lacks access to the technical report summary because:

  • obtaining the information would result in an unreasonable burden or expense, or
  • it requested the technical report summary from the owner, operator or other person possessing the technical report summary, who is not affiliated with the registrant, and who denied the request,

and it provides in the applicable registration statement or annual report all the information required by the SEC rules that it does possess or which it can acquire without unreasonable effort and expense.

Return to Top

When must a technical report summary be updated?

The new rules will require the registrant to file an updated technical report summary in connection with the filing of the registrant’s SEC annual report or in connection with an applicable registration statement if, at such time, there has been a material change in the mineral resources or mineral reserves for a material property from that reported in the previously-filed technical report summary, or a material change in the exploration results contained in a technical report summary that the registrant filed voluntarily.

Without limiting the foregoing, a registrant may not rely on a previously filed technical report summary if, at the time of filing the registrant’s SEC annual report or in connection with an applicable registration statement, the registrant is unable to conclude that all material assumptions and information pertaining to the disclosure of a registrant’s mineral resources and mineral reserves, including material assumptions relating to all modifying factors, price estimates, and scientific and technical information (e.g., sampling data, estimation assumptions and methods), are current as of the end of the registrant’s most recently completed fiscal year.

Due to the number of requirements with which a technical report summary must comply, an updated technical report summary may, in practice, be required on an annual or other regular basis.

Return to Top

What information must be included in every technical report summary?

Every technical report summary filed with the SEC must:

  • be prepared, signed and dated by each qualified person responsible for the technical report summary; provided, that in the case of a qualified person that is not an employee of and not otherwise affiliated with the registrant, a third-party firm comprising mining experts, such as professional geologists or mining engineers, may date and sign the technical report summary instead of, and without naming, the individual qualified person employed or affiliated with the firm that prepared the technical report summary;
  • avoid the inclusion of large amounts of technical or other project data, either in the report or as appendices to the report,
  • conform, to the extent practicable, with “plain English” principles,
  • otherwise comply with subpart 1300 of Regulation S-K,

and comply with detailed disclosure requirements in the following general categories: (i) executive summary, (ii) introduction, (iii) property description, (iv) accessibility, climate, local resources, infrastructure and physiography, (v) history, (vi) geological setting, mineralization and deposit, (vii) exploration, including hydrogeology, and geotechnical data, testing and analysis, (viii) sample preparation, analyses, and security, (ix) data verification, (x) adjacent properties, (xi) other relevant data and information, (xii) interpretation and conclusions, (xiii) recommendations, (xiv) references, and (xv) reliance on information provided by the registrant.  The details on disclosure for each of these categories are set forth in the rules.  See Appendix B.

What additional information must be included in a technical report summary that reports exploration results?

None.

Return to Top

What additional information must be included in a technical report summary that reports the results of an initial assessment and, if applicable, mineral resources?

A registrant’s disclosure of mineral resources must be based upon a qualified person’s initial assessment, which supports the determination of mineral resources.  As explained above in the discussion of mineral resources, the initial assessment must include the qualified person’s qualitative evaluation of applicable modifying factors to establish the economic potential of the mining property or project.  The technical report summary submitted by the qualified person to support a determination of mineral resources must describe the procedures, findings and conclusions reached for the initial assessment.  In addition to the information required to be included in every technical report summary, a technical report summary that reports the results of an initial assessment must include detailed disclosure in the following general categories: (i) mineral processing and metallurgical testing and (ii) mineral resource estimates.  The details on disclosure for each of these categories are set forth in the new rules.  See Appendix B.

A qualified person may, but is not required to, apply modifying factors to the mineral resources to include an economic analysis in the initial assessment.

To assist qualified persons in understanding the disclosure requirements in an initial assessment relating to modifying factors, the new rules include Table 1, extracted below, which describes certain information the qualified person is required or permitted to disclose, or permitted to assume, in an initial assessment relating to modifying factors.

What additional information must be included in a technical report summary that reports the results of a preliminary feasibility (pre-feasibility) study or a final feasibility study and, if applicable, mineral reserves?

A registrant’s disclosure of mineral reserves must be based upon a qualified person’s pre-feasibility study or feasibility study which supports a determination of mineral reserves.  The pre-feasibility or feasibility study must include the qualified person’s detailed evaluation of all applicable modifying factors to demonstrate the economic viability of the mining property or project.  The technical report summary submitted by the qualified person to support a determination of mineral reserves must describe the procedures, findings and conclusions reached for the pre-feasibility or feasibility study.  In addition to the information required to be included in a technical report summary that reports the results of an initial assessment, a technical report summary that reports the results of a pre-feasibility or feasibility study must include detailed disclosure in the following general categories: (i) mineral reserve estimates, (ii) mining methods, (iii) processing and recovery methods, (iv) infrastructure, (v) market studies, (vi) environmental studies, permitting, and plans, negotiations or agreements with local individuals or groups, (vii) capital and operating costs, and (viii) economic analysis.  The details on disclosure for each of these categories are set forth in the new rules.  See Appendix B.

What information must a registrant disclose in its SEC filings regarding all of its mining properties, including those that are non-material?

Registrants are currently required to disclose under Guide 7 information regarding mines, plants and significant properties owned or operated, or presently intended to be owned or operated, by the registrant.

The new rules would require differing levels of disclosure regarding a mining property depending on whether the property is material to the registrant.  If a registrant with material mining operations has more than one mining property that it:

  • Owns or in which it has, or it is probable that it will have, a direct or indirect economic interest;
  • Operates, or it is probable that it will operate, under a lease or other legal agreement that grants the registrant ownership or similar rights that authorize it, as principal, to sell or otherwise dispose of the mineral; or
  • Has, or it is probable that it will have, an associated royalty or similar right,

then it must provide in its SEC annual report and applicable registration statements the following information regarding all such properties, including both material and non-material properties:

  • A map or maps, of appropriate scale, showing the locations of all properties. Such maps should be legible on the page when printed.
  • An overview of the registrant’s mining properties and operations.  The overview must include aggregate annual production for the properties during each of the three most recently completed fiscal years preceding the filing.  It should also include, as relevant:

    • The location of the properties;
    • The type and amount of ownership interests;
    • The identity of the operator or operators;
    • Title, mineral rights, leases or options and acreage involved;
    • The stages of the properties (exploration, development or production);
    • Key permit conditions;
    • Mine types and mineralization styles; and
    • Processing plants and other available facilities.

    When presenting the overview, the registrant should include the amount and type of disclosure that is material to an investor’s understanding of the registrant’s properties and mining operations in the aggregate.  A registrant should refer to, rather than duplicate, any disclosure concerning individually material properties provided elsewhere in the document.

  • A summary of all mineral resources and mineral reserves, as determined by the qualified person, at the end of the most recently completed fiscal year by commodity and geographic area and for each property containing 10% or more of the registrant’s combined measured and indicated mineral resources or containing 10% or more of the registrant’s mineral reserves.  This summary must be provided for each class of mineral resources (inferred, indicated and measured), together with total measured and indicated mineral resources, and each class of mineral reserves (probable and proven), together with total mineral reserves, using a tabular format set forth in the new rules.  
Registrants that hold only royalties, streaming or other similar rights with respect to a material property are subject to the foregoing disclosure requirements; however, if such a registrant lacks access to any of the required information, such registrant may omit such information, provided that the registrant:
  • Specifies the information to which it lacks access;
  • Explains that it does not have access to the required information because:
    • Obtaining the information would result in an unreasonable burden or expense, or
    • It requested the information from a person possessing knowledge of the information, who is not affiliated with the royalty company or similar registrant, and who denied the request; and
  • Provides all required information that it does possess or which it can acquire without incurring an unreasonable burden or expense.

What information must a registrant disclose in its SEC filings regarding properties that are individually material to the registrant?

In its SEC annual report and in applicable registration statements, a registrant engaged in mining operations would be required to disclose certain property-specific information for each property that is material to the registrant’s business or financial condition.  While the new rules do not specify how a registrant should determine what is an individual “property”, versus multiple properties, the SEC  noted in the proposing release that properties sharing the same processing plant or other facilities prior to the first point of material external sale could be treated as one mining property.  This suggests that such determinations should not be made on a strictly legal basis but should instead be based on how such properties are situated or operated.

The new rules acknowledge that some registrants have material mining operations but do not have any single property that is material to the registrant’s business or financial condition; for example, a registrant may have 50 distinct properties, none of which is individually material.  A registrant with no individually material properties need not comply with the disclosure requirements described in this section.

In addition to information similar to current Guide 7 requirements, the new rules require, with respect to each material property:

  • Tabular disclosure of mineral resources and mineral reserves;
  • Additional narrative disclosures; and
  • As previously described, filing as an exhibit a technical report summary prepared by one or more qualified persons in support of any estimate of material resources, any estimate of material reserves, any material change in the foregoing or any material change in a voluntarily-filed technical report summary relating to exploration results.

The new rules require that a registrant engaged in mining operations include in its annual reports and applicable registration statements the following information with respect to each property that is material to the registrant’s business or financial condition:

  • A brief description of the property including:
    • The location, accurate to within one mile, using an easily recognizable coordinate system. The registrant must provide appropriate maps, with proper engineering detail (such as scale, orientation, and titles). Such maps must be legible on the page when printed;
    • Existing infrastructure including roads, railroads, airports, towns, ports, sources of water, electricity, and personnel; and
    • A brief description, including the name or number and size (acreage), of the titles, claims, concessions, mineral rights, leases or options under which the registrant and its subsidiaries have or will have the right to hold or operate the property, and how such rights are obtained at this location, indicating any conditions that the registrant must meet in order to obtain or retain the property. If held by leases or options or if the mineral rights otherwise have termination provisions, the registrant must provide the expiration dates of such leases, options or mineral rights and associated payments.
  • If the registrant’s interest in the property is through a royalty, streaming or other similar right, a brief description of the agreement under which the registrant and its subsidiaries have or will have the right to a royalty or similar interest in the property, indicating any conditions that the registrant must meet in order to obtain or retain the royalty or similar interest, and indicating the expiration date.
  • The following information, as relevant to the particular property:
    • A brief description of the present condition of the property, the work completed by the registrant on the property, the registrant’s proposed program of exploration or development, the current stage of the property as exploration, development or production, the current state of exploration or development of the property, and the current production activities. Mines should be identified as either surface or underground, with a brief description of the mining method and processing operations. If the property is without known reserves and the proposed program is exploratory in nature or the registrant has started extraction without determining mineral reserves, the registrant must provide a statement to that effect;
    • The age, details as to modernization and physical condition of the equipment, facilities, infrastructure, and underground development; and
    • The total cost for or book value of the property and its associated plant and equipment;
  • A brief history of previous operations, including the names of previous operators, insofar as known;
  • A brief description of any significant encumbrances to the property, including current and future permitting requirements and associated timelines, permit conditions, and violations and fines;
  • If mineral resources or reserves have been determined, a tabular summary of all mineral resources or reserves as of the end of the most recently completed fiscal year, presented for each class of mineral resources (measured, indicated and inferred), together with total measured and indicated mineral resources, the estimated tonnages and grades (or quality, where appropriate), and in a separate table, for each class of mineral reserves (proven and probable), together with total mineral reserves, the estimated tonnages, grades (or quality, where appropriate), cut-off grades and metallurgical recovery, based on a specific point of reference selected by the qualified person.
  • A comparison of the property’s mineral resources and reserves as of the end of the last fiscal year with the mineral resources and reserves as of the end of the preceding fiscal year, with an explanation of any material change between the two.  The comparison must disclose information concerning:
    • The mineral resources or reserves at the end of the last two fiscal years;
    • The net difference between the mineral resources or reserves at the end of the last completed fiscal year and the preceding fiscal year, as a percentage of the resources or reserves at the end of the fiscal year preceding the last completed one;
    • An explanation of the causes of any discrepancy in mineral resources including depletion or production, changes in commodity prices, additional resources discovered through exploration, and changes due to the methods employed; and
    • An explanation of the causes of any discrepancy in mineral reserves including depletion or production, changes in the resource model, changes in commodity prices and operating costs, changes due to the methods employed, and changes due to acquisition or disposal of properties;
  • If the registrant has not previously disclosed mineral reserve or resource estimates in a filing with the SEC or is disclosing material changes to its previously disclosed mineral reserve or resource estimates, a brief discussion of the material assumptions and criteria in the disclosure and cite to corresponding sections of the technical report summary, which must be filed as an exhibit.
  • To the extent material to investors, a discussion of exploration activity and exploration results, including:
    • If disclosing exploration activity for any material property for the most recently completed fiscal year, a summary that describes the sampling methods used, and, for each sampling method used, the number of samples, the total size or length of the samples, and the total number of assays; and
    • If disclosing exploration results for any material property for the most recently completed fiscal year, a summary that, for each property, identifies the hole, trench or other sample that generated the exploration results, describes the length, lithology, and key geologic properties of the exploration results, and includes a brief discussion of the exploration results’ context and relevance.  If the summary only includes results from selected samples and intersections, it should be accompanied with a discussion of the context and justification for excluding other results. 
  • If the registrant is disclosing exploration results not previously disclosed in a filing with the SEC, or material changes to previously disclosed exploration results, provide sufficient information to allow for an accurate understanding of the significance of the exploration results. This must include information such as exploration context, type and method of sampling, sampling intervals and methods, relevant sample locations, distribution, dimensions, and relative location of all relevant assay and physical data, data aggregation methods, land tenure status, and any additional material information that may be necessary to make the required disclosure concerning the registrant’s exploration results not misleading. If filing a technical report summary, the registrant must cite to corresponding sections of the summary technical report, which must be filed as an exhibit.  A change in exploration results that significantly alters the potential of the subject deposit is considered material.
  • If the registrant includes disclosure of an exploration target, such disclosure must appear in a separate section of the filing that is clearly captioned as a discussion of an exploration target.  This section must include:
    • A clear and prominent statement that:
      • The ranges of potential tonnage and grade (or quality) of the exploration target are conceptual in nature;
      • There has been insufficient exploration of the relevant property or properties to estimate a mineral resource;
      • It is uncertain if further exploration will result in the estimation of a mineral resource; and
      • The exploration target therefore does not represent, and should not be construed to be, an estimate of a mineral resource or mineral reserve.
    • A detailed explanation of the basis for the exploration target, such as the conceptual geological model used to develop the target;
    • An explanation of the process used to determine the ranges of tonnage and grade, which must be expressed as approximations;
    • A statement clarifying whether the exploration target is based on actual exploration results or on one or more proposed exploration programs, which should include a description of the level of exploration activity already completed, the proposed exploration activities designed to test the validity of the exploration target, and the time frame in which those activities are expected to be completed; and
    • A statement that the ranges of tonnage and grade (or quality) of the exploration target could change as the proposed exploration activities are completed.
Registrants that hold only royalties, streaming or other similar rights are subject to the foregoing disclosure requirements; however, if such a registrant lacks access to any of the required information, such registrant may omit such information, provided that the registrant:
  • Specifies the information to which it lacks access;
  • Explains that it does not have access to the required information because:
    • Obtaining the information would result in an unreasonable burden or expense, or
    • It requested the information from a person possessing knowledge of the information, who is not affiliated with the royalty company or similar registrant, and who denied the request; and
  • Provides all required information that it does possess or which it can acquire without incurring an unreasonable burden or expense.

What other information must a registrant disclose in its SEC filings?

Under the new rules, every registrant with mining operations that are material to its business or financial condition must describe in its SEC annual report and applicable registration statements the internal controls that the registrant uses in its exploration and mineral resource and reserve estimation efforts.  This disclosure should include quality control and quality assurance (QC/QA) programs, verification of analytical procedures and a discussion of comprehensive risk inherent in the estimation.

In addition, if a registrant has filed a technical report summary with respect to any property, the registrant must identify the qualified person who prepared the technical report summary and state whether the qualified person is an employee of the registrant.  If the qualified person is not an employee of the registrant, the registrant must name the qualified person’s employer, disclose whether the qualified person or the qualified person’s employer is affiliated with the registrant or another entity that has an ownership, royalty or other interest in the property that is the subject of the technical report summary, and if affiliated, describe the nature of the affiliation.

May a registrant disclose historic mineral resources, mineral reserves or material exploration results that the registrant has been unable to verify?

Only in limited circumstances.  If a report containing a mineral resource, mineral reserve or other estimate relating to a property was prepared before the registrant acquired, or entered into an agreement to acquire, an interest in the property, and the registrant has not verified the information as a current estimate of mineral resources, mineral reserves, or exploration results, then such information is not considered current and cannot be filed in support of disclosure.  Notwithstanding this prohibition, a registrant may include such an estimate in an SEC filing that pertains to a merger, acquisition or business combination if the registrant is unable to update the estimate prior to the completion of the relevant transaction.  In that event, when referring to the estimate, the registrant must disclose the source and date of the estimate, and state that a qualified person has not done sufficient work to classify the estimate as a current estimate of mineral resources, mineral reserves, or exploration results, and that the registrant is not treating the estimate as a current estimate of mineral resources, mineral reserves, or exploration results.

May a registrant include in its SEC filings supplemental disclosures that do not comply with the SEC’s new rules, but comply with a foreign mining code such as Canada’s NI 43-101?

Not in its core “filed” SEC reports, such as Form 10-Ks, 10-Qs and 20-Fs, and certain Form 8-Ks.  Nor can such information be incorporated by reference into a non-MJDS SEC registration statement.  

However, the SEC’s new rules will not prohibit a registrant from including supplemental disclosures that are inconsistent with the SEC’s rules in disclosures that are not subject to the rules, such as disclosures on an issuer’s website, in press releases or in certain SEC submitted documents such as a Form 8-K furnished under Regulation FD, or for foreign private issuers a Form 6-K that is not incorporated by reference into an applicable registration statement.  This is consistent with the existing reporting regime for U.S. issuers, under which many U.S. issuers voluntarily prepare technical reports and other disclosures that comply with NI 43-101 or other foreign standards and make such reports available to the public outside their core “filed” SEC reports.  As under existing Guide 7, a registrant seeking to make such supplemental disclosures should assure itself that neither such disclosures nor its SEC filings are misleading.

The new rules will change the existing practice of Canadian issuers that file on non-MJDS forms including Forms 20-F, F-1, F-3 and F-4.  Existing Guide 7 includes an exception that permits the disclosure of information that would otherwise be prohibited by Guide 7, if such information is required by foreign or state law.  The SEC has taken the view that only Canada requires by law compliance with a particular mining disclosure code (NI 43-101).  In addition, the SEC has not permitted U.S. issuers that are subject to Canadian disclosure requirements to take advantage of the exemption.  Accordingly, the prevailing SEC guidance is that Canadian issuers filing with the SEC on non-MJDS forms are permitted to disclose NI 43-101 compliant information (which would otherwise violate Guide 7) in their SEC filings, as long as the filings are not misleading and the registrant also includes the information that would be required by Guide 7.  U.S. issuers and registrants from other countries are not permitted to vary from Guide 7.  As initially proposed by the SEC, the final new rules eliminate this exception on the basis that, because the new rules permit the disclosure of mineral resources and are generally consistent with other CRIRSCO-based reporting regimes, such an exception is no longer be necessary.

Could a qualified person be liable if information contained in the technical report summary is incorrect or misleading?

Yes.  U.S. securities laws allow the purchaser in a public offering of securities to sue the registrant, its directors, and any officer that signed the SEC registration statement for the offering, if the registration statement pursuant to which the securities were sold “contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading . . . ”, and the purchaser suffered damages.  A purchaser may also sue any accountant, engineer, or other expert who has, with his or her consent, been named in the registration statement, with respect to the statements attributed to him.  This would include any qualified person named as the author of a technical report summary.

Notwithstanding the foregoing, a person (other than the registrant) generally will not be liable if after reasonable investigation, the person had reasonable grounds to believe and did believe that the statements were true and that there was no material omission.  This is known as the due diligence defense.  A qualified person may therefore avoid liability, even in the case of a materially misleading statement or omission, if the qualified person conducted appropriate due diligence and had reasonable grounds to believe and did believe in the accuracy of the disclosure. 

Liability for misleading disclosures is not limited to public offerings. Rule 10b-5 under the Securities Exchange Act of 1934 makes it unlawful to “make any untrue statement of a material fact or to omit to state a material fact necessary in order to make the statements made, in the light of the circumstances under which they were made, not misleading . . . in connection with the purchase or sale of any security.”  Under this rule, claims for damages may be made in respect of securities purchased in private placements.  In addition, lawsuits may be brought against a registrant or other persons alleged to have “made” untrue or misleading statements to the market generally, seeking damages on behalf of persons that purchased or sold securities in the market in reliance upon such information. The applicable standards for such claims are complex and beyond the scope of this discussion. 

The filing of such lawsuits as class actions is common in the United States. Defendants may agree to settle such actions as an otherwise costly nuisance.  Because plaintiffs’ attorneys may be entitled to receive fees in such settlements, even ones with little benefit to the purported class of affected shareholders, it is common for plaintiffs’ attorneys to bring class action lawsuits against companies that have experienced a significant drop in stock price as a result of an unfavorable disclosure, or that are engaged in a sale of the company.

Many qualified persons are already subject to these potential liabilities, because they act for registrants that are Canadian companies, and that pursuant to Canada’s NI 43-101 have been identified in such registrants’ SEC registration statements and reports.

      • State with equal prominence to the disclosure of mineral resource estimates that the assessment is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have modifying factors applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that this economic assessment will be realized;
      • Disclose the percentage of the mineral resources used in the cash flow analysis that was classified as inferred mineral resources; and
      • Disclose, with equal prominence, the results of the economic analysis excluding inferred mineral resources in addition to the results that include inferred mineral resources.
    • Operating and capital cost estimates must have an accuracy level of at least approximately ±50% and a contingency level of no greater than 25%.  The qualified person must state the accuracy and contingency levels in the initial assessment.

Further Required Additions for a Preliminary Feasibility Study or a Final Feasibility Study:

The qualified person must disclose the price used for each commodity, which must provide a reasonable basis for establishing that the project is economically viable, and explain, with particularity, his or her reasons for using the selected price, including the material assumptions underlying the selection. This explanation must include disclosure of the time frame used to estimate the price and costs and the reasons justifying the selection of that time frame. The qualified person may use a price set by contractual arrangement, provided that such price is reasonable, and the qualified person discloses that he or she is using a contractual price when disclosing the price used; 
    • When the qualified person reports the grade or quality for a multiple commodity mineral reserve as metal or mineral equivalent, he or she must also report the individual grade of each metal or mineral and the commodity prices, recoveries, and any other relevant conversion factors used to estimate the metal or mineral equivalent grade.

    When this information is included in a pre-feasibility study:

    • The qualified person must exclude inferred mineral resources from the pre-feasibility study’s demonstration of economic viability in support of a disclosure of a mineral reserve;
    • Factors to be considered are typically the same as those required for an initial assessment, but considered at a greater level of detail or at a later stage of development.  For example, a pre-feasibility study must define, analyze or otherwise address in detail:
      • The required access roads, infrastructure location and plant area, and the source of all utilities (e.g. power and water) required for development and production;
      • The preferred underground mining method or surface mine pit configuration, with detailed mine layouts drawn for each alternative;
      • The bench lab tests that have been conducted, the process flow sheet, equipment sizes, and general arrangement that have been completed, and the plant throughput;
      • The environmental compliance and permitting requirements or interests of agencies, non-governmental organizations, communities and other stakeholders, the baseline studies, and the plans for tailings disposal, reclamation and mitigation, together with an analysis establishing that permitting is possible; and
      • Any other reasonable assumptions, based on appropriate testing, on the modifying factors sufficient to demonstrate that extraction is economically viable.
    • The pre-feasibility study must also identify sources of uncertainty that require further refinement in a final feasibility study.

    When this information is included in a final feasibility study:

    • The qualified person must exclude inferred mineral resources from the pre-feasibility study’s demonstration of economic viability in support of a disclosure of a mineral reserve;
    • A feasibility study must contain the application and description of all relevant modifying factors in a more detailed form and with more certainty than a pre-feasibility study.  The list of factors is not exclusive.  For example, a feasibility study must define, analyze or otherwise address in detail, to the extent material:
      • Final requirements for site infrastructure, including well-defined access roads, finalized plans for infrastructure location, plant area, and camp or town site, and the established source of all required utilities (e.g. power and water) for development and production;
      • Finalized mining method, including detailed mine layouts and final development and production plan for the preferred alternative with the required equipment fleet specified.  The feasibility study must address detailed mining schedules, construction and production ramp up, and project execution plans;
      • Completed detailed bench lab tests and a pilot plant test, if required, based on risk.  The feasibility study must further address final requirements for process flow sheet, equipment sizes, and general arrangement and specify the final plant throughput;
      • The final identification and detailed analysis of environmental compliance and permitting requirements, and the completion of baseline studies and finalized plans for tailings disposal, reclamation and mitigation; and
      • The final assessments of other modifying factors necessary to demonstrate that extraction is economically viable.
