Executive Summary
The Whistler Gold-Copper Project process plant is designed to treat 40,000 t/d of mineralized material from the Whistler gold-copper porphyry deposit. This plant recovers copper, gold and silver by froth flotation and leaching to produce copper concentrate and gold doré over a 14.6-year mine life.
The process flowsheet for the project is based on preliminary metallurgical laboratory testing, as discussed in Section 13, and preliminary economic modelling. The selected unit operations are conventional technologies commonly applied in copper and gold processing plants of similar throughput. The proposed flowsheet includes the following process areas and unit operations: Crushing, Grinding, Copper flotation, Copper concentrate handling, Gold leaching, Gold recovery and carbon regeneration, and Cyanide destruction and tailings management.
The life-of-mine (LOM) average feed grades and recoveries are summarized in Table 17-1. Copper feed grade is 0.16%, Gold feed grade is 0.44 g/t, and Silver feed grade is 1.83 g/t. Average overall recovery over LOM is 77.8% for Copper, 88.9% for Gold, and 55.6% for Silver.
