Executive Summary
This technical report section outlines the recovery methods and processing plant specifications for a copper-silver-gold sulphide operation. The facility utilizes a standard crush-grind-flotation circuit designed to operate two 12-hour shifts daily, 365 days a year, with a targeted plant availability of 92%. The installed capacity is planned to be stabilized at 45 kilotonnes per day (kt/d) throughout 2024 and 2025, with a subsequent expansion to 50 kt/d by 2027.
The comminution circuit employs a primary and secondary crushing stage to reduce feed size to minus 40 mm before processing through a semi-autogenous grinding mill, ball mill, and pebble crusher circuit. This reduces the feed size to a P80 of 150 micrometers. The resulting slurry enters a sulphide flotation circuit which produces a copper-silver-gold concentrate. The concentrate is dewatered using pressure filters and stored on-site prior to transport via truck to the Port of Vancouver for shipment.
Operational plans indicate a ramp-up schedule where throughput will increase from 41.1 kt/d in 2024 to 50.0 kt/d by 2027. This expansion involves minor capital upgrades to remove bottlenecks in the primary and secondary crushing circuits rather than adding major new equipment. Recovery rates for copper and gold are projected to improve slightly over this period, with copper recovery targeting 86% and gold recovery targeting 68% by 2027.
