The USGS and BGS Critical Minerals Lists — From 50 to 60 Commodities in Three Years
National critical-minerals lists have stopped being static reference documents and become live
policy instruments — the United States expanded its list from 50 to 60 minerals in November 2025,
while the United Kingdom's 2024 reassessment nearly doubled its "critical" count from 18 to 34.
These lists now feed directly into tariff exemptions, permitting fast-tracks, and stockpiling budgets,
which raises the stakes of every methodology choice behind them.
1. USGS Mineral Commodity Summaries and the statutory list mechanic
The U.S. Geological Survey publishes the annual Mineral Commodity Summaries
as the authoritative baseline for U.S. production, reserves, and import-reliance data across roughly 90
commodities, with the 2025 edition running to hundreds of commodity-specific pages
(USGS, Mineral Commodity Summaries 2025)
and the 2026 edition continuing the series
(USGS, Mineral Commodity Summaries 2026).
The critical minerals list itself is a separate, legally mandated product under the
Energy Act of 2020, which requires the Secretary of the Interior to review and, if
necessary, revise the list at least every three years using a methodology that screens each mineral for
supply-chain risk, import dependence, and essential use in energy, defense, and economic
security applications. The 2022 Final List of Critical Minerals contained 50 minerals and
was published as a Federal Register notice
(USGS, 2022 Final List of Critical Minerals — Federal Register Notice,
USGS, U.S. Geological Survey Releases 2022 List of Critical Minerals).
2. The 2025 revision: draft 54, final 60
The Interior Department's draft 2025 list, released August 26, 2025, proposed 54 minerals
— adding potash, silicon, copper, silver, rhenium, and lead while proposing to remove arsenic and
tellurium. After a formal comment period and interagency review, the final 2025 list,
released November 6–7, 2025, settled at 60 minerals: arsenic, boron, metallurgical
coal, phosphate, tellurium, and uranium were added back in response to public and agency input, on top of
the draft's new entrants
(USGS, Interior Department Releases Final 2025 List of Critical Minerals,
Federal Register, 2025 Final List of Critical Minerals (Doc. 2025-19813)).
The methodology behind both the draft and final lists — including the supply-risk scoring formula and
data sources for each screened mineral — is documented in an open-file report
(USGS, Open-File Report 2025–1047, 2025 Critical Minerals List Methodology).
The headline structural change is that copper and silver — both large-volume,
exchange-traded metals rather than niche technology inputs — are now formally "critical" for the
first time, alongside potash (fertilizer security) and rhenium (superalloys); a Congressional Research
Service report walks through exactly which minerals moved between the draft and final versions and why
(Congressional Research Service, U.S. Critical Minerals List: 2025 Update (R47982)).
3. The UK's parallel exercise: BGS 2024 Criticality Assessment
The British Geological Survey runs its own periodic criticality assessment, independent of
the U.S. methodology but built on a comparable economic-importance-versus-supply-risk matrix. The
UK 2024 Criticality Assessment, published November 28, 2024, screened 82 candidate
materials and rated 34 as critical — nearly double the 18 materials rated critical
in the prior 2021 assessment — with a ranked top ten led by niobium, cobalt, and rare earth elements
(British Geological Survey, UK 2024 Criticality Assessment).
Notable additions versus 2021 include nickel, iron, germanium, aluminium, and chromium, while palladium
dropped off the list entirely — a divergence from the U.S. list, which retains palladium as critical,
illustrating that "critical" is jurisdiction-specific rather than a fixed geological fact. Between the
UK and US lists, the only consistent throughline is rare earth elements, cobalt, and gallium,
which both surveys rank in their respective top tiers. The practical consequence for any reference
platform is that a single global "critical minerals" badge is analytically imprecise: a mineral can be
critical to the UK's industrial base (niobium, ranked first in the 2024 BGS assessment) while sitting
outside the top tier of the U.S. list, and vice versa for minerals such as potash and rhenium that the
U.S. added in 2025 but that do not appear in the UK's ranked top ten at all
(British Geological Survey, UK 2024 Criticality Assessment,
USGS, Interior Department Releases Final 2025 List of Critical Minerals).
Current status: the U.S. list is now 60 minerals
following the November 2025 final rule, with copper and silver newly designated — a change with direct
tariff and permitting consequences under the Energy Act framework; the UK's 34-mineral 2024 list runs on an
independent methodology and diverges from the U.S. on palladium and several base metals, meaning any
tokenized-metals platform citing "critical mineral" status must specify which country's list it is using.

National Resource Inventories — Geoscience Australia's AIMR and the Global Race to Map Reserves
Geoscience Australia's Australia's Identified Mineral Resources (AIMR) 2025 report, released
March 2, 2026, confirms Australia holds the world's largest Economic Demonstrated Resources of nine
separate commodities — a national-inventory model that the U.S. and China are now trying to
replicate through cross-border data-sharing initiatives rather than competing surveys.
1. AIMR 2025: what Australia's survey actually tracks
Geoscience Australia compiles the AIMR report annually, tallying Economic
Demonstrated Resources (EDR) — the local equivalent of Proved and Probable reserves — across
every commodity mined in the country, with the 2025 edition covering data through December 31, 2024.
Australia holds the world's number-one ranking for EDR of gold, iron ore, lead, rutile,
uranium, vanadium, zinc, zircon, and, newly added in this edition, ilmenite; the country is also a top-five
global supplier of 14 separate commodities
(Geoscience Australia, Release of Australia's Identified Mineral Resources 2025 (AIMR) Report,
Geoscience Australia, AIMR 2025 — Introduction).
Exploration investment behind that inventory reached AUD 3.95 billion in 2024, funding the
drilling and assay work that feeds directly into the EDR figures. Australia's own domestic
Critical Minerals List, last revised February 20, 2024, names 31 commodities — a
materially different set from either the U.S. 60-mineral list or the UK's 34, reflecting Australia's
specific export exposure to lithium, rare earths, and cobalt
(Geoscience Australia, Australia's Critical Minerals List).
2. Resourcing Australia's Prosperity — a 35-year, AUD 3.4 billion commitment
Behind the annual AIMR snapshot sits a long-horizon data-generation program: Resourcing Australia's
Prosperity is a 35-year national precompetitive geoscience initiative, running 2024–2059,
with AUD 3.4 billion in committed funding to systematically map the continent's subsurface mineral
potential ahead of private exploration capital
(Geoscience Australia, Critical Minerals scientific topic page
and program detail at
Geoscience Australia, National Resource Assessments — Resourcing Australia's Prosperity).
This is precompetitive geoscience in the literal sense: the government funds the baseline surveys, then
releases the data publicly so junior explorers do not have to each re-fund basic geophysical mapping before
staking claims — a direct subsidy to the front end of the Lassonde curve.
3. Cross-border data pooling: the Critical Minerals Mapping Initiative
Rather than each country building a duplicate global inventory, the Critical Minerals Mapping
Initiative (CMMI) pools data across the Geological Survey of Canada, Geoscience
Australia, and USGS, combining their national datasets into what the partners describe as the
world's largest harmonized "Critical Minerals in Ores" dataset
(Geoscience Australia, Critical Minerals scientific topic page).
This tri-national pooling model sidesteps the classification-harmonization problem entirely: instead of
agreeing on one reserve-reporting standard, the three surveys keep their own national systems and share
raw ore-chemistry and deposit data, letting downstream users re-run their own criticality screens.
Current status: Australia's AIMR remains the
most granular public national resource inventory in the world, refreshed annually with a year's lag; the
CMMI tri-national data pool (Canada/Australia/USGS) is the most advanced cross-border harmonization effort in
production today, though it pools raw data rather than reconciling classification systems.

Reserve Classification Cross-Mapping — CRIRSCO, China's GB/T 17766-2020, and Peru's INGEMMET
China's 2020 shift to a CRIRSCO-compatible three-tier resource classification — Inferred,
Indicated, Measured — formally ended two decades of running a parallel Soviet-derived A/B/C1/C2
system, closing the largest remaining classification gap in global reserve reporting. Peru's
INGEMMET, by contrast, adopted CRIRSCO-style terminology directly and now issues technical reports that
read almost identically to a Canadian NI 43-101 filing.
1. CRIRSCO as the harmonization umbrella
The Committee for Mineral Reserves International Reporting Standards (CRIRSCO) maintains
the template that NI 43-101 (Canada), JORC (Australia), and SAMREC (South Africa) all derive from, built
around the shared vocabulary of Measured/Indicated/Inferred Resources and Proved/Probable Reserves. China's
own delegation has participated in CRIRSCO harmonization discussions for over a decade, with a formal
country profile now published on the CRIRSCO site describing the Mineral Resources and Reserves Evaluation
Center as China's link into the template
(CRIRSCO, China Country Profile).
2. China's GB/T 17766-2020: from the A/B/C1/C2 system to three-tier confidence
China's current national standard, GB/T 17766-2020, Classifications for Mineral Resources and
Mineral Reserves, took effect May 1, 2020, replacing the 1999 edition and definitively retiring the
older A/B/C1/C2 categories inherited from the Soviet-era classification system that had
persisted in parallel use for pre-1999 project data
(SRK Consulting, JORC and the Chinese Resource Classification System).
The 2020 standard classifies mineral resources into Inferred, Indicated, and Measured
tiers by geological confidence, converting Measured and Indicated resources into Proved and
Probable reserves once a pre-feasibility or feasibility study establishes economic viability
— a structure explicitly aligned with, though formally independent of, both CRIRSCO and the United
Nations Framework Classification (UNFC). China's Ministry of Natural Resources and the UNECE jointly
published a bridging document mapping GB/T 17766-2020 categories directly onto UNFC codes
(UNECE, Bridging Document: China GB/T 17766-2020 and UNFC).
The China Geological Survey now reports national reserve totals under the new standard,
combining proved and probable reserves for most solid minerals
(China Geological Survey, China Mineral Resources).
3. Peru's INGEMMET: CRIRSCO vocabulary without a formal CRIRSCO seat
Peru's Instituto Geológico, Minero y Metalúrgico (INGEMMET) operates as the
country's national geological survey and mining-title registry, publishing its own resources-and-reserves
methodology that defines Recurso Medido/Indicado/Inferido (Measured/Indicated/Inferred
Resource) in terms matching the CRIRSCO template almost word for word
(INGEMMET, Recursos y Reservas 2016).
In practice, technical reports filed with INGEMMET for Peruvian projects are frequently the same documents
prepared for Canadian or Australian listing purposes, since most foreign-funded Peruvian exploration
companies are simultaneously listed on the TSXV or ASX and must produce an NI 43-101- or JORC-compliant
report regardless of the domestic filing requirement, as seen in technical reports hosted in INGEMMET's own
library
(INGEMMET Library, SRK Technical Report 168-2012).
This makes Peru a case of de facto harmonization through dual compliance rather than a
formal CRIRSCO membership arrangement.
Current status: as of mid-2026, the practical
classification landscape has converged more than headline national-standard names suggest — China's
GB/T 17766-2020 and Peru's INGEMMET framework both now speak the Measured/Indicated/Inferred and
Proved/Probable vocabulary that CRIRSCO, JORC, and NI 43-101 use, even where formal CRIRSCO membership or a
UNFC bridging document is the only paperwork connecting the systems.
