In March 2019, Leagold completed a Feasibility Study (FS) for the Los Filos expansion project, outlining the potential for development of the Bermejal underground mine, enlargement of the Los Filos open pit mine, re-phasing of the Bermejal open pit into two distinct sections (Bermejal and Guadalupe), and construction of a 4,000 tonne per day carbon-in-leach (CIL) processing facility to complement the existing heap leach facilities.
Lycopodium delivered the CIL metallurgical test work management and interpretation and the processing plant and related process infrastructure design for both the FS and NI 43-101 compliant Technical Report.
Equinox subsequently identified an opportunity to increase the throughput of the CIL plant, with Lycopodium supporting the Equinox team to optimise the scope of the project with the development of an FS for the optimised design.
Key Highlights
- Single-stage SAG milling to reduce capital
- Provision for future expansion without significantly increasing initial capital
