Gualcamayo — Deep Carbonates (DCP): gold and silver (Minas Argentinas)
Reactivation and deepening of the Gualcamayo gold and silver mine (San Juan): the 'Deep Carbonates (DCP)' project extends the mine life toward the sulfide orebody at depth. Company/press figures (probable, outside the resolution): ~4,500 projected direct and indirect jobs; the operator is preparing a 'second RIGI' (~USD 1,500 M) to move from a mine to a mining district.

- The works, milestone by milestone — We have not built this project’s timeline. Dated milestones with their source close it.
- Who already has a contract — We have not surveyed this project’s awards. A published contract with its source closes them.
How to supply itwhere to register, what they ask for and what they will buy
How to become a supplier
We have not built this project’s entry map. It is our gap, not a prohibition: it closes by opening the provincial register and the operator’s single window.
What it will buy, and when
Each phase buys different things at different times.
Exploration, feasibility and construction of the processing plant
under wayThe approved purpose is the exploration of the Gualcamayo 1 and 2 concessions, the feasibility of the Carbonatos Profundos deposit and «the construction, start-up and operation of the processing plant». Investment plan: USD 46,741,254 in the first year and USD 43,858,696 in the second, counted from the admission date. ⚠️ The act does not declare a start-up date.
What it will need and has no supplier for yet
Deep drilling and underground mine development (deep carbonate mining)
mediumMoving from the depleted open pit to the deep orebody demands specialized drilling, ground support and underground development, different from the historical open-pit work.
Assembly and repowering of the mineral processing plant
mediumBuilding and commissioning the plant for the new orebody (investment deadline 31-Dec-2028) concentrates electromechanical works capex.

What it leaves in San Juanjobs, works, taxes, promises and the outlook
How many jobs it creates
230 new jobs for the nine months of the infrastructure works that started in August 2026, on top of a workforce of 327 direct workers and 437 contractor workers ⚠️ this is employment for the PRELIMINARY infrastructure works (accommodation, roads, power), not for the construction of the Carbonatos Profundos plant, which nobody publishes prob · Aug 14, 2026 ↗
- The works that stay behind — We have not surveyed this project’s permanent works. A published size with its source closes them.
- What it already pays in taxes and royalties — We have not broken down this project’s local fiscal contribution: the primary source that sets each item still has to be opened, and an act of the State is not published on press backing.
- Who promised what — We have not surveyed the public promises about this project. A dated, verifiable commitment with its source closes them.
What could stall itrisks and how to track them
- What could stall it — We have not documented this project’s risks. An identifiable vector with its source closes them.
- How to tell whether it is advancing — We have not defined this project’s indicators: what observable fact marks its progress still has to be identified.

There are 1 in this project. Each says why it could not be confirmed and what it would take to close it.

What is published, and loaded here, is the previous step: 230 jobs for nine months of infrastructure works. For the big stage —the construction of the plant— there is no figure in an accessible source, and Resolución 6/2026 does not publish employment.
