Diablillos — gold and silver (Salta/Catamarca)
Gold and silver mining in the puna, on the Salta/Catamarca border area: feasibility development, a 3.15 Mt/yr processing plant and full infrastructure. Official portal: 2,013 jobs (direct and indirect).
How to supply it
what we have for a supplier, and how to request it
What we have on this project for a supplier
Who decides the purchase, who you invoice and where a new supplier registers.
Which lines each phase buys and when the window opens for each one.
Which they are, why it will need them and who could provide them.
Who they are, what each one does and how to sell to them.
All of this is surveyed and verified against its source. Crossed with what you sell —which of them your products suit, how to reach it and when— it is in your company report. Request the report
We cross what you manufacture or do against the 2 phases of this project and tell you which ones you fit into and when each one buys. Two pages, with the evidence behind them.

The works, milestone by milestone
AbraSilver issues Worley a limited notice to proceed for the bridging engineering, opening the workstreams needed for the final investment decision, set for the second quarter of 2027. The scope includes planning the construction and operations camp.
AbraSilver closes a public equity offering of C$50 million (C$49,994,700 gross), earmarked to advance Diablillos, including early works and advance purchase of long-lead equipment.
Catamarca approves the project's environmental impact statement, the last major environmental permit it still lacked according to the owner.
AbraSilver publishes the results of the definitive feasibility study: a 9,000 t/day plant, a 25-year mine life, USD 722 M of initial capex, a 1,600-person camp to be built after the investment decision, and a grid connection in year 3 of operation.
Resolución 562/2026 is published in the official gazette, approving accession to the RIGI: a 3,150,000 t/yr plant, USD 481.7 M in eligible assets and a commitment of 55% of purchases from local suppliers.
RIGI accession date set by article 2 of Resolución 562/2026. ⚠️ It is neither the date of the resolution nor of its publication: the resolution sets it retroactively, 70 days before it was signed and 74 before it was published.
AbraSilver selects Worley as the engineering contractor for the definitive feasibility study, with the work run from its Canadian and Argentine offices.

The works that stay behind
The infrastructure that stays standing once the works end, with its size and its source.
Tank leach processing plant, with its tailings storage facility
Productivetonnes of ore per day, for a 25-year mine life; US$722 million of initial investment, contingency included
The cooperation zone between Salta and Catamarca: it is the industrial facility that sustains a quarter century of activity in the department, and the study raises a possible expansion of the tailings facility for future mine-plan scenarios.
The definitive feasibility study sets out an open-pit operation with a 9,000 tonnes-per-day tank leach plant, initial capex of USD 722 million —including USD 98 million of contingency— and sustaining capex of USD 520 million over the life of the mine. The tailings facility incorporates a downstream waste-rock buttress, and the study raises as a possibility an expansion of the facility designed for future expansions of the mine plan.
- 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 it
risks 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.

What we could not confirm
There are 3 in this project. Each says why it could not be confirmed and what it would take to close it.
H-01How many people the construction employs and how many stay working in operation+
No RIGI admission resolution publishes the figure: the seventeen that are published state that the company «provided the estimate of direct and indirect employment of the Project with local integration» and do not transcribe it. The official RIGI portal publishes a single figure that adds direct and indirect jobs together and does not separate the two stages, and mixing them is exactly the error the `empleo` field exists to prevent.
H-02The permanent infrastructure the project leaves behind+
The definitive feasibility study announces a grid connection in year 3 and a 1,600-person camp, but the release publishes neither the length nor the voltage of the line, nor the kilometres of access road, nor the water system. Without a magnitude an item does not enter the permanent-works block, and the gap is not filled with the Puna's regional infrastructure: the roughly 250 km high-voltage line under discussion for the lithium corridor is a different project, not Diablillos.
H-03The route of the power connection, the access road and the water system+
The feasibility study publishes that the grid connection arrives in year 3 — until then the project runs on diesel generators — but it does not give the length or the voltage of the line, the kilometers of the access road, or how water is supplied. A work with no magnitude does not enter the inventory of what stays built, so all three are left out until a measurement appears.
We look at what your company does and tell you whether we see a sign that it fits this market, with the evidence behind it. If we do not see one, we say so too and name the condition that would change it. One page as a dated PDF, within 48 working hours.
