Mineral Reserves and Resources Data: The Stock Figures, Delivered

Reserves questions come from two directions, and the data splits the same way. National geological agencies assess what sits in the ground; securities regulators capture what listed companies say they can extract economically. Of the 16 datasets Datadory pools under Diversified Metals & Mining, two carry reserve and resource stock figures directly: Geoscience Australia - Minerals Data and SEC EDGAR - Mining Company Filings.

Australia's Identified Mineral Resources (AIMR) is the annual national assessment covering all major and some minor commodities, with editions archived back to 1983 - more than four decades of trend depth. Regulation S-K 1300 disclosures sit inside Item 2 Properties of 10-K and 20-F annual reports: company-level, tied to a fiscal year, published the moment the SEC accepts the filing. Everything else on the shelf supplies operating context - production tables, mine rosters, exploration spending - around those stock figures.

The two families behave differently, which is exactly why they are worth holding together. The national assessment gives you the deposit universe including ground nobody mines yet; the disclosure layer gives you the economics only operators know. A screen built on one without the other either misses early-stage assets or over-trusts promotional tonnage.

Geoscience Australia - Minerals Data, scored 9 out of 10 on Datadory's quality rubric. Its AIMR 2025 edition states Australian reserves and resources as at 31 December 2024 and ships as roughly 20 per-commodity point layers - Antimony, Bauxite, BlackCoal, Cobalt, Copper, Diamond, Gold, Graphite, IronOre among them - with the copper layer alone carrying 406 deposit features.

Every feature documents the same attribute set: entity_id, state, commodity, currentstatus (Deposit or Operating mine), mineraldeposittype, units, a banded size_ class, longitude, latitude and a source citation string. A real row shows the granularity: Abra in Western Australia as commodity "Copper", currentstatus "Deposit", units "Mt", size class "<0.5", at longitude 118.587279 and latitude -24.643101.

Because each point carries a status flag, the same layers distinguish deposits from operating mines - which is what lets a screen separate exploration-stage ground from producing assets before any filing data enters the picture. AIMR editions from 1983 onward remain available for trend work, and the companion Australian Mineral Exploration Review has reviewed calendar-year activity since 2009 using drilling metres and ASX maiden-resource announcements - the latter flagging newly reported resource statements as they appear. Behind both sits the Resourcing Australia's Prosperity program, a 35-year, AUD 3.4 billion initiative running 2024-2059.

For listed producers, SEC EDGAR - Mining Company Filings is the authoritative record, scored 9 out of 10 in the catalog. Foreign private issuers file 20-F annual reports each spring - Vale S.A. (SIC 1000 Metal Mining) landed its last three on 27 March 2026, 28 March 2025 and 19 April 2024 - while domestic producers such as Freeport-McMoRan and Southern Copper file 10-Ks each February, BHP Group and Rio Tinto plc filing alongside them. Scale is no object: the ticker map covers 10,387 companies, and the 2026 Q2 master index alone lists 352,957 filing rows, 1,191 of them 10-Ks.

One structural caveat decides how you model this. Miners frequently tag production tonnage with custom extension concepts that have no standard mapping, so reserve tonnages do not always resolve to a single clean tagged fact the way revenues do. Treat the structured XBRL layer as the financial spine and read the SK-1300 reserve tables from the filing documents themselves - full-text search over filings since 2001 locates "SK 1300" statements across issuers when you need the population.

A sample request returns the filings layer cut to the registrants and form types you name, with the reserve tables extracted rather than left buried in exhibits.

Canada contributes both the physical roster and the money flow. Mining Association of Canada - Facts & Figures, scored 7 out of 10, published its 128-page 2026 edition in May 2026 covering calendar year 2024. Annex 1 lists about 90 producing Canadian mines, each row naming COMPANY, MINE SITE, ACTIVITY TYPE (P for open pit, U underground, C concentrator), LOCATION and a COMMODITY code - Vale Newfoundland and Labrador at Voisey's Bay coded (P., U., C.), Rio Tinto's Diavik underground with Plant, Agnico Eagle's Meliadine beside them. Annex 5 is the reserves series, reaching back to 1978: up to 47 years of national reserve history in one table.

The flow side belongs to Natural Resources Canada - Mineral Statistics, scored 8 out of 10. Its exploration and deposit appraisal survey runs twice yearly, so $4,400.4 million of preliminary 2025 spending already sits beside stated company intentions for 2026, broken out by commodity group - base metals, precious metals, iron, uranium, nonmetals, diamonds, coal. The annual production file complements it with 1,951 rows of commodity-by-jurisdiction output across all ten provinces and three territories, three measures deep.

Read together, the pair answers the question a static reserve table cannot: whether a jurisdiction's next generation of deposits is being found faster than the current one is mined out.

Ranked by directness of reserve-and-resource coverage first, then by how cleanly each loads into a pipeline. All four arrive through Datadory in one normalized channel; none of the paywalled sources in this industry slice - the study-group bulletins, LBMA benchmark history - carries reserve stock figures anyway.

A workable screen chains them. Start in the AIMR layers to shortlist deposits by commodity, size class and status. Join operator and asset names against the filings layer to see who discloses the resource publicly and what tonnage they claim. Then read the expenditure trend out of Natural Resources Canada to judge whether a jurisdiction's pipeline is expanding or contracting. Three joins, zero pipeline builds.

Four blocks, in order:

1. Anchor on the deposit universe. Load the AIMR commodity layers once per edition - they are fixed annual snapshots, which is a feature for reproducibility - and filter on currentstatus plus the banded size_ class to get a candidate list. Label the stock-date (31 December 2024 for AIMR 2025) in the table itself, not the publication date.
2. Join the disclosure layer by operator. Map entity and operator names against the SEC registrant list, then pull each match's most recent annual report for the Item 2 reserve tables. Expect the join rate to be partial: most Australian deposits have no US-listed operator, and that absence is itself information about stage.
3. Add the flow axis. Attach Natural Resources Canada's expenditure columns by jurisdiction and commodity group so the screen can distinguish shrinking provinces from expanding ones. Watch the revision flags - preliminary years move.
4. Reconcile against world totals. World Mining Data's country-by-commodity panel, 65 raw materials across 168 producer countries with market shares and Herfindahl-Hirschman concentration indices, catches attribution errors before they reach a memo.

Datadory delivers the whole chain as typed rows in one feed - daily, weekly, or hourly, your call - so the snapshot layers and the flowing ones never drift apart between refreshes. Native grains map onto delivery tiers cleanly: filings as they are accepted, the national assessment on release, expenditure tables semi-annually, production tables annually.

Investors and quant researchers read the deposit-to-disclosure gap as a staging signal, then benchmark claimed tonnage against national assessments before it goes near a valuation. See investors quants use cases.

Commodity strategists and procurement teams track reserve depletion against the expenditure pipeline so supply outlooks key off both the stock in the ground and the money finding the next one.

Market researchers and consultants size regional mining economies off the producing-mine roster joined to provincial production values, with the 47-year Canadian reserves series anchoring the long view.

Data scientists and ML engineers train deposit-ranking models on the coordinate-carrying AIMR features, using the status flags as labels and World Mining Data's shares as an aggregate consistency check.

Journalists, academics and students quote the 406-deposit copper layer and the reserves-to-1978 series with stock-dates attached, so no stale vintage ends up in print. See journalists academics use cases.

Every one of these jobs runs off the same normalized rows - delivered daily, weekly, or hourly, your call - so the workflow is a sample request away rather than a quarter of pipeline maintenance.

Start with the two records behind this article: request a sample of Geoscience Australia - Minerals Data cut to your commodities and states, and the SEC EDGAR mining filings layer scoped to your registrant list. Then the diversified metals mining data hub ranks the whole slice with field dictionaries, sample rows and delivery terms on every card, and the diversified metals mining data guide maps how the 25-dataset landscape fits together.

Sibling clusters extend the frame: the corporate layer at mining company XBRL financial data, the output side at copper production by country dataset and the worked single-country case at Chile copper production statistics.
