CRIRSCO has 16 member national reporting organisations as of August 2026, each administering one CRIRSCO-aligned code, including JORC, NI 43-101, SAMREC, PERC, KAZRC, and CAMRA (China's newest member, joined 16 October 2025). The US applies Regulation S-K 1300 directly through the SEC. Tajikistan and Turkmenistan remain outside CRIRSCO, still using the Soviet GKZ classification.
Every row below was checked against crirsco.com and, where possible, a second primary source (exchange listing rules, national regulator, or the code text itself) during this update. This table is re-verified quarterly; CRIRSCO adds or reclassifies members several times a year, so treat any copy older than a quarter as a starting point, not a citation.
CRIRSCO, the Committee for Mineral Reserves International Reporting Standards, is the body that sets the common definitions national mineral reporting codes build on. It does not itself certify a single company's reserves or license Competent Persons; it certifies that a national code meets a shared minimum standard, then leaves enforcement to each country's own reporting organisation and, in most jurisdictions, to the stock exchange that makes the code mandatory for listed issuers.
The committee traces back to 1994, when a Mineral Definitions Working Group was formed at the 15th Congress of the Council of Mining and Metallurgical Institutions (CMMI) in Sun City, South Africa, with representatives from Australia (AusIMM), Canada (CIM), South Africa (SAIMM), the UK (IMM), and the United States (SME). That group's job was to reconcile the definitions each country used for exploration results, mineral resources, and mineral reserves into one comparable framework. The name later changed to the Committee for Mineral Reserves International Reporting Standards, and the CRIRSCO acronym stuck. CRIRSCO has been a Strategic Partner of the International Council on Mining and Metals (ICMM) since 2009 and is recognised by the UN Economic Commission for Europe (UNECE) as a source framework for the UNFC mineral classification.
Not every national mining code sits under CRIRSCO's umbrella. VALMIN, Australia's code for independent technical valuations and expert reports, is a separate instrument aimed at valuation rather than resource and reserve classification, and it is not one of the 16 codes in the CRIRSCO membership list below; see the VALMIN Code overview for where it does and does not overlap with JORC.
The current edition of the CRIRSCO International Reporting Template is the June 2024 Update, approved for release on 27 June 2024. The template is not itself a reporting code a company can comply with directly; it is the master document each national organisation aligns its own code to, covering the shared definitions for Exploration Results, Mineral Resources, and Mineral Reserves, the three-tier resource confidence scale (Measured, Indicated, Inferred), and the two-tier reserve scale (Proved/Proven, Probable).
The template has gone through three major iterations that matter for anyone reading an older technical report: the original 2006 template that first consolidated the post-Bre-X definitions, a substantial November 2019 update that most of the current national codes (PERC 2021, for instance) are explicitly aligned to, and the June 2024 update layered on top of that. A code that cites "the 2019 CRIRSCO template" and one that cites "the 2024 CRIRSCO template" are not necessarily in conflict, but a reviewer should check which version a Competent Person's Report was actually written against.
This is the full list of mineral reporting codes by country currently recognised as CRIRSCO members, with the national reporting organisation (NRO), the code it administers, and the year it joined CRIRSCO where that year is independently verifiable. Sixteen members, one NRO each, one code each.
| Country / region | National reporting organisation (NRO) | Code | Joined CRIRSCO | Notes |
|---|---|---|---|---|
| Australasia (Australia, New Zealand) | JORC (Joint Ore Reserves Committee) | JORC Code, 2012 Edition | 1994 (founding) | Next edition in final drafting with ASX, ASIC and CRIRSCO; target finalisation Q1 2026, per JORC's own update page. |
| Canada | CIM (Canadian Institute of Mining, Metallurgy and Petroleum) | CIM Definition Standards (2014) with NI 43-101 (2011 amendment) | 1994 (founding) | CIM definitions are incorporated by reference into the securities-law instrument NI 43-101, not standalone. |
| Europe | PERC (Pan-European Reserves & Resources Reporting Committee) | PERC Reporting Standard 2021 | 1994 (founding, as the IMM Code lineage) | Mandatory since 1 January 2023; the prior PERC 2017 edition was usable through a 2021 to 2022 transition window. |
| South Africa | SAMCODES (SAMREC Committee) | SAMREC Code, 2016 Edition | 1994 (founding) | Embedded directly in Section 12 of the JSE Listings Requirements. |
| United States | SME (Society for Mining, Metallurgy and Exploration) | SME Guide, 2017 Edition | 1994 (founding) | The SEC's Regulation S-K 1300 uses the same CRIRSCO-based classification scheme rather than adopting the SME Guide by reference. |
| Chile | Comisión Minera (Chilean Mining Commission) | Chilean Mineral Resources and Reserves Certification Code | 2003 | First non-founding member. |
| Russia | NAEN historically; crirsco.com's live members list currently shows OERN against this row | NAEN Code | 2011 | Source conflict between crirsco.com/members/ and CRIRSCO's own code documentation; verify directly before citing, see the callout below. |
| Mongolia | MPIGM (Mongolian Professional Institute of Geosciences and Mining) | MPIGM Code | 2014 | Not represented at CRIRSCO's October 2022 annual general meeting, per CRIRSCO's own chair. |

Terminology across CRIRSCO-family codes is not a loose translation exercise; it is the same five categories reused verbatim, because every current code in the table above is built on the same International Reporting Template scaffold. Regulation S-K 1300 confirms this explicitly: the SEC adopted "a CRIRSCO-based classification scheme" for US mining registrants rather than inventing its own resource categories, replacing the old reserves-only Industry Guide 7. See S-K 1300 vs. JORC for the practical filing differences that do exist.
| Category | What it means | Codes using this exact term |
|---|---|---|
| Measured Mineral Resource | Highest-confidence resource tier; grade, tonnage and continuity known with enough certainty to support detailed mine planning. | JORC, CIM/NI 43-101, SAMREC, PERC, KAZRC, S-K 1300, and the other CRIRSCO-family codes |
| Indicated Mineral Resource | Middle-confidence resource tier; enough drill and sample spacing to assume geological continuity but not to the precision of Measured. | Same list |
| Inferred Mineral Resource | Lowest-confidence resource tier, inferred from geological evidence with limited sampling; cannot convert directly to a Reserve. | Same list |
| Proved / Proven Mineral Reserve | Economically mineable portion of a Measured Resource after applying Modifying Factors. | Same list |
| Probable Mineral Reserve | Economically mineable portion of an Indicated (or, in limited cases, Measured) Resource after applying Modifying Factors. | Same list |
Where codes genuinely diverge is not the category names but the mechanics around them: who is allowed to sign as a Competent Person or Qualified Person, what a Technical Report Summary must contain, how often public issuers must re-state figures, and whether the exchange or the securities regulator is the enforcing body. Those are code-specific rules, not classification differences, and they are the part worth checking case by case rather than assuming from the shared vocabulary.
| Exchange | Country | Required code | Rule |
|---|---|---|---|
| ASX (Australian Securities Exchange) | Australia | JORC Code | Listing Rule 5.6 requires compliance with the JORC Code; the Code is itself incorporated as Appendix 5A. Chapter 5 prevails over JORC wording if the two conflict. |
| TSX and TSX Venture Exchange | Canada | NI 43-101 (incorporating CIM Definition Standards) | National Instrument 43-101, a Canadian Securities Administrators rule, effective since 2001 and last substantially amended 30 June 2011; not an exchange rule but a securities-law requirement that binds every TSX/TSXV mining issuer. |
| JSE (Johannesburg Stock Exchange) | South Africa | SAMREC Code | Section 12 of the JSE Listings Requirements, applicable to any company classified as a Mineral Company. |
| AIX (Astana International Exchange) | Kazakhstan | JORC, NI 43-101, or KAZRC (issuer's choice) | AIX Mining Company Rules, approved by the Astana Financial Services Authority, accept a Competent Person's Report under any of the three named codes. |
| NYSE and Nasdaq (SEC-regulated issuers) | United States | Regulation S-K, Subpart 1300 | Adopted 31 October 2018 (Release No. 33-10570); mandatory for the first fiscal year beginning on or after 1 January 2021, replacing Industry Guide 7. |
Tajikistan and Turkmenistan are the two clear cases: both remain fully reliant on the Soviet-era GKZ mineral reserves classification, with no CRIRSCO transition underway, according to the OECD's April 2026 regional note on Central Asian critical minerals. GKZ differs from every code in the table above in one structural way: it does not separate Resources from Reserves the way JORC-family codes do, and it reports "balance reserves" against a state-approved threshold instead of a Competent Person's economic and technical judgement. For the mechanics of converting an old GKZ A/B/C1/C2/P category into a JORC-family equivalent, see the practical GKZ to JORC conversion guide and the fuller GKZ to JORC conversion reference.
Two other countries sit in between and are easy to misclassify. Uzbekistan adopted JORC directly for reporting purposes in 2019 to 2020 while phasing out GKZ internally, but it is not itself a CRIRSCO member and JORC is not "Uzbekistan's code" in the way KAZRC is Kazakhstan's. Kyrgyzstan transitioned toward CRIRSCO-aligned reporting in 2017 and launched its own UN-backed KyrRC system, approved in 2024, with dual GKZ and KyrRC use still permitted on major projects and full integration targeted for 2030; Kyrgyzstan also does not appear on CRIRSCO's own 16-member list. Both are worth flagging separately from Kazakhstan in any due-diligence note: "CRIRSCO-aligned" and "CRIRSCO member" are not the same claim, and conflating them is one of the more common errors in outside analysis of the region.
Digitising and reclassifying the underlying Soviet archive is the harder half of any of these transitions, since the source documents are OCR-unfriendly scans in a projection (Pulkovo 1942) that does not map cleanly onto WGS-84 without reprojection work; see Soviet archive digitisation for what that process actually involves.
CRIRSCO's code-documentation pages still tie Russia's 2011 entry to NAEN, the National Association for Subsoil Use Auditors, and NAEN's own code text describes OERN, the Russian Society of Subsoil Use Experts, as the professional body operating under NAEN rather than as the NRO itself. But CRIRSCO's live members list at crirsco.com/members/ currently shows OERN, not NAEN, against Russia's 2011 row, a change from what most secondary sources still report. Separately, CRIRSCO's chair told the committee's October 2022 general meeting in Johannesburg that Russia (along with Mongolia) was not represented that year, with no reason given, against a backdrop of Western sanctions that already limit any practical capital-markets benefit of CRIRSCO membership for Russian issuers. Treat "Russia is a CRIRSCO member" as formally listed but operationally unclear, including which body currently holds NRO status, and check crirsco.com/members/ directly before repeating either name as a settled fact.
A membership list is only as useful as its refresh cycle. CRIRSCO added a 16th member in October 2025 (CAMRA, China), and JORC's next Code edition is due to finalise with ASX, ASIC and CRIRSCO in the first quarter of 2026, which will move at least one row in the "current edition" column shortly after this page was last checked. Cross-referencing the master table above against a client's actual filings, rather than trusting any single cached copy including this one, is the same discipline CoreElement AI applies internally: its standards-mapping module tracks JORC 2012, NI 43-101, KAZRC, SAMREC, PERC 2021, S-K 1300 and CRIRSCO category mappings against source documents, including a dedicated module for reprojecting and reclassifying Soviet GKZ A/B/C1/C2/P records into CRIRSCO-aligned categories. It is a reference tool built for exactly the kind of cross-code checking this page describes, not a replacement for reading the current code text yourself.
