COSE Project — 2012 Technical Report

This report presents a preliminary economic assessment of the Cap Oeste Suroeste (COSE) Project in Santa Cruz Province, Argentina, effective 10 August 2012.

Report context

The COSE Project technical report was prepared for Patagonia Gold PLC with an effective date of 10 August 2012. The report documents a preliminary economic assessment covering mineral resources, mining methods, and recovery methods for the Cap Oeste Suroeste project located in Santa Cruz Province, Argentina. The document includes sections on property description, geology, mineralization, exploration, drilling, sampling, assaying, data verification, mineral resource estimates, mining methods, and recovery methods.

Processing route

Historical and testwork basis

The processing and metallurgical testing section of the report includes gravitational concentration testing and bottle roll tests. Screen fire assays were performed as part of the metallurgical testwork program. The report indicates that preliminary results from these tests informed the proposed process design, though specific numerical outcomes from individual tests are not presented in the available sections.

Proposed process

The proposed process is described in the report under Section 17.5, which outlines the conceptual processing flowsheet for the project. The report does not provide additional details on equipment selection, mass balances, or plant layout within the extract provided.
