- 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 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.
Construction of the plant and the site
under wayVerbatim from the act: «estimating a total construction time from the month of July 2026, and an estimated start of operation for July 2029». It includes the 3,150,000 t/yr plant, waste dumps, stockpile areas, a service centre, a truck shop, a warehouse, offices, laboratories, a construction and operation camp, a contractors’ yard, access roads, water and power. The investment plan for the first two years is USD 98,500,000 and USD 253,900,000, with a Nov 30, 2027 deadline.
They are not buying any of this today. Open the phase to see the detail and arrive qualified the day it goes to tender.
What it will need and has no supplier for yet
Grinding and process plant maintenance
highIt is the ONLY RIGI project in Salta with a grinding plant: 9,000 t/d (3.15 Mt/year). The copper, gold and silver dossier flags it as an open gap in the province — nobody in Salta currently maintains mills of that class, and the package (relining, liner changes, alignment, vibration analysis, heavy-gauge welding) would today be imported from Chile or San Juan. It is a high-value-per-hour service with a scheduled shutdown window, and whoever gets certified during construction goes on to operate it.
Fire assay of gold and silver, and grade control
highA silver and gold deposit controls its grades by fire assay, a laboratory line distinct from the brine characterization required by Rincón and Sal de Oro: same industry, different equipment and different accreditation. It is the hard-rock leg of Salta's laboratory niche.
High-altitude civil works and electromechanical assembly, 2027-2029 window
mediumAbraSilver's DFS places construction from 2027, peaking in 2028-2029 and at 4,100-4,650 m above sea level. Demand is large but CONDITIONAL, which is why this hypothesis is not sealed any higher: the project has no regulatory obstacle (environmental impact statement and RIGI already approved) and its open gate is financing, with a final investment decision expected in the second quarter of 2027.

What it leaves in Saltajobs, works, taxes, promises and the outlook
- 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.

What we could not confirm
There are 1 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.
