Executive Summary
The San Miguel Project Preliminary Economic Assessment (PEA) outlines a mining operation designed to process oxide and mixed ores through heap leaching, with a milling and cyanide leach circuit planned for later years. The project encompasses multiple deposits including San Miguel, San Francisco, Monte Cristo, La Veronica, San Antonio, La Union, and Don Ese. Recovery assumptions vary by material type, with mill ore generally showing higher gold recoveries (68-95%) compared to leach ore (0-81%).
Operating costs were estimated based on similar North American mining operations and test work results. The processing cost is assumed to be $13.75 per tonne for milled ore and $3.00 per tonne for heap leached ore on a weighted average basis. The total project recovery is estimated at 86% for gold and 57% for silver when combining both milling and leaching processes.
The report details specific recovery assumptions for various production locations, highlighting the efficiency differences between open pit leaching and underground milling operations. This technical report serves as a foundational document for the economic viability of the San Miguel Project under the current development stage.
