The deposit 27
Key takeaway. Management describes the Marimaca oxide deposit, which they say starts at 700 m above sea level, as having a base-case plan of 50,000 tons per annum and a 13-year reserve life, with the oxide resource delivering at least 25,000 tons of…

incremental cathode supply. The company also points to a district-scale sulfide system at Pampa Medina (starting at 1,000 m above sea level) that they believe could become a tier-one discovery—defined as something that can produce 100,000 tons of copper for 20 years plus—and to multiple shallow oxide discoveries with stepout holes 900 meters to the south hitting the same sedimentary horizon (Nov 2025, May 2026, Jul 2026). They report grades that include nearly 40 meters at 1.5%, nearly 50 meters at 2% in a broader zone of 160 meters at 1%, and very consistent zones of more than 20 meters at more than 1% copper in just about every drill hole, with the dominant mineral species being borite and chalkite, both leachable (Nov 2025, May 2026).

Key takeaway. Management describes the project as having multiple manageable technical risks.

They note that the asset is well-located with a manageable height and proximity to port, which they say reduces execution risk (Jul 2026). However, they acknowledge "an element of risk as a first-time builder" (Jan 2026). More recently, the company reported that DFS timing has experienced delays, drill results are coming slower than expected, and that the environmental impact assessment — under review by 17 technical agencies — is key (Nov 2025). On the geological side, management states that postmineral dyking is "very important for how this deposit is formed" and that previously interpreted barren dikes are now showing mineralization (Nov 2025).

Economics 5

They state that unit operating costs per ton of ore will be very competitive against other sediment basins, supported by equipment and input costs prevalent in the Chilean mining industry (May 2026; January 2026). The company reports using a $4.30-per-pound copper price assumption, which implies a valuation for the MOD (likely the sulphide project) of about $8.60 per share based on a 7× NAV multiple (January 2026; July 2026).

Read the full summary
In January 2026, the company was targeting end of 2026 for build readiness, with construction start and first production both expected "sometime during the course of 2026." By May 2026, management said they were deep into detail design and engineering, running debt financing, and ready to start early PreFID construction work at the end of the year, while noting an initial inferred resource was due in 6 to 7 months and that 35,000 m of drilling would be completed by the end of September. In July 2026, management added that a Sergio geological interpretation presentation would come "in the next couple of days" and that a Pampa sulfides maiden resource would follow in the early part of 2027.
