(2) All-in-Sustaining Costs include cash costs plus sustaining, refining and reclamation costs, as well as 2% royalty buyout.
Mineral Resource Estimate
The PEA utilizes the updated Mineral Resource Estimate (MRE) contained in the technical report prepared by SRK and titled “NI 43-101 Technical Report: Mineral Resource Estimate, Cerro Caliche Project, Sonora, Mexico” with an effective date of January 26, 2023 and report date of March 24, 2023. The updated MRE is based on a total 55,360 meters of drilled data, including 498 drill holes, 17 trenches and assays for 53,865 meters of the drilled data.
PEA Summary
The PEA is preliminary in nature and includes inferred resources that are considered too speculative to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty the estimates presented in the PEA will be realized.
The PEA demonstrates the potential viability for a nine-year life of mine (“LOM”), open pit, heap leach mining operation with an initial two-year production rate of 4,000 metric tonnes per day (“mtpd”) and an increase to 12,000 mtpd for the remaining LOM.
