Cuba: online, and nothing to read
The Oficina Nacional de Recursos Minerales holds the registry, the concession control and, under Decreto-Ley 10 of 2020, occupational safety in mining and petroleum. Its site is a working, modern one. It publishes Ley 76 de Minas of 1994, the decrees, a monthly bulletin of registry acts and an annual summary: 429 concessions in force at the end of 2025 (243 exploitation, 123 exploitation and processing, 34 investigation, 26 processing, 3 reconnaissance). It publishes no concession list, no accident and no enforcement output. The sector is nickel and cobalt at Moa, in a joint venture with Canada's Sherritt, plus construction materials, all state enterprises.

- ONRM's yearly registry summary: the concession count by kind, a total and never a list.
- ONRM's monthly Actos Registrales bulletins, the only recurring concession stream, as HTML index entries with the documents behind a document store.
- ONRM's regulatory library (Ley 76, Decreto-Ley 10, Decreto 160 of 2026 on non-state mining) and a technical archive of 11,661 items from 1840, by signed contract and paid service.
- ONEI's statistical yearbook, chapter on mining and energy, over plain HTTP only.
- A per-concession list: the front page advertises a Concesiones Mineras panel; whether it resolves to one was not established.
- An accident, inspection or sanction publication from ONRM, MINEM or the labour ministry, although ONRM holds the safety mandate in law.
- A live signal: no Cuban body publishes a mining accident and the independent press works from outside the country. Sherritt's disclosures as a Canadian issuer cover the Moa joint venture only, in aggregate.
By nobody, publicly. The only channel with a legal obligation attached is Sherritt's quarterly and annual safety reporting to Canadian markets, which covers the Moa joint venture in aggregate and no other Cuban operation.
None. Cuba has no freedom-of-information law. The functional equivalent is ONRM's commercial information service: a framework contract, a request form and a fee, returning a certified report from the archive. For this site that is a vendor relationship with a sanctioned-country state entity, a compliance question before a data one, and it is not pursued.
Whether the Concesiones Mineras panel resolves to a per-concession list. If it does, Cuba becomes a thin register-only country; if not, it stays this note.
