Executive Summary
The 2018 Preliminary Economic Assessment for the Santa María Silver Project outlines the proposed recovery methods for the project’s mineral resources. The plan involves toll-milling both mixed and sulfide materials at an external facility equipped with sulfide flotation circuits. The maximum throughput for the flotation circuit is set at 250 tonnes per day, designed to produce a bulk sulfide silver-gold bearing concentrate.
Oxide ore is designated for cyanide leaching at the toll-milling facility. Testwork indicates an option to process mixed and sulfide tailings in the leach circuit to improve gold and silver recovery. While a zinc flotation circuit exists downstream of the lead circuit at the facility, it is not utilized in the proposed flowsheet, though it offers flexibility for alternative processing strategies.
