Checking the status of a tenement, CFEM collection and earlier decisions by the ANM Board requires different systems. The ANM’s Mapa da Mina (“Mine Map”) guide presents the agency’s 26 data panels and systems in a single document.
But for anyone making decisions about an area, the starting point is usually a question: Is the area occupied? Where does this tenement stand? For that reason, this text reorganizes the guide around those questions and shows what each system provides, and what it does not.
Which panel answers which question
| Question | Where to look | Caution |
|---|---|---|
| Is the area occupied? By whom? | SIGMINE, then Mining Registry (Cadastro Mineiro) | The map shows location and lets you upload your own layer to check overlaps. The phase and events of the tenement are on the Registry record. |
| Where does a tenement stand? | Mining Registry and ANM Public SEI | They are different layers: registry data and administrative progress. |
| Is there a sanction or an annual fee per hectare (TAH) collection against the titleholder? | CONAD | Search by tenement or case number, CPF or CNPJ (taxpayer IDs). |
| Which areas may be offered? | Availability Rounds | The stock shows what may be offered, not when. |
| How much does the sector produce, invest and export? | AMB Interativo, ComexMin, MCE 360 | AMB and MCE 360 are updated once a year. |
| How much CFEM has been collected? | CFEM Observatory | It shows collection only. Transfers are in the National Treasury and Banco do Brasil systems. |
| How does the Board usually decide? | Board Deliberations, ANMlegis, Regulatory Agenda | It shows past decisions, not forecasts. |
One tenement, three searches
A mining tenement appears in three places, and each one tells part of the story. The Mining Registry holds the record: phase, titleholder, substances, polygon and main events. The ANM Public SEI shows the administrative progress and the public documents, and allows requests to be filed. CONAD brings together administrative sanction proceedings and the collection of the annual fee per hectare (TAH). Anyone checking ownership or risk by looking only at the Registry record misses what is moving through the SEI and what is in administrative litigation.

Data has an expiry date
The guide states how often each resource is updated, from real time to annual. The AMB Interativo depends on submission of the Annual Mining Reports (RAL) for the previous year, so it cannot be used for current-year production. The MCE 360, which gathers data on 24 substances, is also annual; see what it lets you read in Rare Earths in Brazil: How an Area Moves from Exploration to Production. The map of CFEM collection and distribution by municipality and year covers 2008 to 2023, and the ANM itself states that the last update was in 2023. Before citing a figure in a report or legal opinion, note which panel you used and the date you consulted it.
What the panels do not answer
The panels show data; they do not say what to do with it. Knowing that a tenement is in a given phase does not tell you which requirements are pending, or what the safest next step is. The guide’s other resources, such as the Technical Cooperation Agreements (ACT), the Strategic Plan and Budget Execution, mainly serve public managers and researchers; those who want to download the databases and cross-reference them on their own should use Open Data.
When the panel is not enough
The panels report what is on record. Deciding on the basis of that record takes a technical reading that cross-checks the tenement’s history against the applicable rules. A common case: in the Mining Registry, the area of interest appears with an extinguished tenement. Is it already free for an application, or must the ANM still formally make it available? The panel shows the phase, but what that phase means for your application depends on someone who reads the history and the rule.
ÍGNEA provides this analysis through three services: Free Areas Evaluation, before the application; Administrative Due Diligence, which checks the status of the tenement and the risks to the project or to the acquisition of the title; and Regulatory Advisory, which supports strategic planning for the tenement.
