LOS FILOS

MINING

A mine plan was developed for the project to process a total of 24 Mt/a of ore.  Three ore types have been identified for processing discretely; these are:

• crushed and agglomerated leach ore from Los Filos only
• run-of-mine ore from Los Filos
• run-of-mine ore from Bermejal.

Crushed leach ore from Los Filos will be processed at the rate of 4 Mt/a.  ROM ore from both Los Filos and Bermejal is scheduled to make up the remaining 20 Mt/a to meet the total ore requirement of 24 Mt/a. The peak total material rate for the project is 66 Mt/a.

The mine is scheduled to work 365 days per year.  Each day will consist of two 10 hour shifts and three mining crews will cover the operation.

The final pit designs are based on floating cones run at gold prices of US$425/oz for Los Filos and US$400/oz for Bermejal.
