Mining and reserve certification
A deposit is an opinion. A certified reserve is an asset.
Brazil is full of idle mineral rights: the title exists, the occurrence is known, and nothing happens — because between the deposit and the money lies a proof almost nobody knows how to conduct. The serious buyer, the listed miner, the natural-resources fund, does not buy geological conviction: it buys a reserve declared by an independent expert, on the yardstick its own market recognises.
The yardstick is international and has a name: JORC in Australasia, NI 43-101 in Canada, S-K 1300 in the United States. Outside them, the asset does not enter the conversation — however good the ore. And certification is not a stamp: it is a data campaign, validation by disinterested third parties, a feasibility study and a dossier that survives the buyer's internal audit.
The house reads the asset whole before any commitment — title and chain of ownership, licences, existing data, logistics and liabilities — and advances only what survives that first audit. From there, it coordinates certification with independent experts, structures the transaction (purchase option, escrow, bilingual contracts) and conducts placement with qualified buyers, with the discretion this market demands.
Where it usually goes wrong: the deposit is sold as if it were a reserve. The global buyer discounts the price for every uncertainty — title still in process, licence not yet started, data without an independent signature — and the negotiation dies in due diligence. The right order is prove first, present afterwards.
A typical case: the owner of a mining concession with old exploration and a valid licence. The existing data is auditable, the complementary campaign is designed to the minimum necessary, and the asset leaves the shelf for the table — with report, structure and counterparty presented one by one, never in an advertisement.
A mining concession with old exploration data and a valid licence. Without certification, the global buyer pays for an opinion and discounts every uncertainty: an offer in the region of R$ 3 million for the title. With a R$ 800,000 complementary campaign and a report to an international standard, the measured reserve goes into a dossier that supports valuation by a multiple of the reserve — and the same deposit comes to be discussed in the tens of millions, with a purchase option and escrow. The difference between the two numbers is the proof, not the ore.
The figures above are from a typical case, with market ranges as of September 2026, to show the arithmetic. Yours comes from your own data, in the diagnosis.
You stop selling a deposit as if it were a reserve. You start receiving the title read, the reserve certified to an international standard and the counterparty at the table — with someone accountable, a deadline and proof, in the same account that looks after the rest of what is not your business.
Structuring declared in writing and a success fee on the completed transaction — the house earns when the asset becomes a deal, not per written opinion.
Official sources, at the exact point: the article of law, the service or the search you can use today. None replaces analysis of the specific case, which is our work.
What the group executes with its own hands, open to the account: works and engineering under its own signature, property and development, certified mining, technology and data, trade fairs and missions, people and management. Whoever engages the reading may also engage the execution — with affiliation declared in writing, always.
We do not promise a result before knowing the case, we do not promise deadlines that are not ours, and we do not chase speculative theses to fatten an opinion. Nor do we take commission for referring anyone: whoever executes answers for the house, within our price.
A conversation, with no materials and no proposal, to understand what is blocked. If there is matter to work on, the next step is the letter of authorisation and secrecy, a document that limits our own access before anything else. If there is not, we say so, and the conversation ends there with no awkwardness for anyone.
Nothing starts without the three in writing. What changes along the way changes by signed addendum, with its cause stated — never by habit.
Payment follows what was delivered and checked, not what was promised. On site, measurement is independent; in other deliveries, the milestone carries proof before it becomes an invoice.
When execution involves a group company, that is said beforehand, in a document. The client chooses knowing who does the work — and may choose someone else.
