Executive Summary
This Preliminary Economic Assessment (PEA) outlines the recovery methods for the Upper Beaver Deposit. Based on metallurgical testwork, a conventional process flowsheet is selected. The process involves crushing and grinding to a 70 micron grind at an average rate of 2,000 tpd. Copper is recovered via flotation to a rougher concentrate, which is then reground and re-floated in a two-stage cleaner circuit. The final concentrate is filtered to 8% moisture for shipment. Flotation tailings undergo leaching in a conventional cyanidation circuit to recover gold.

Executive Summary
This Independent Technical Report covers the Upper Beaver gold-copper Project in Canada. The report is based on a Preliminary Economic Assessment (PEA) and references metallurgical testwork from Section 13 of the PEA report.
The selected process flowsheet is conventional, involving crushing and grinding to a 70 micron grind at an average rate of 2,000 tpd. Copper recovery is achieved via flotation to a rougher concentrate, which is then reground and re-floated in a two-stage cleaner circuit. The final concentrate is filtered to 8 percent moisture for shipment. Gold recovery is handled via cyanidation of the flotation tailings.
