Executive Summary
This section of the NI 43-101 Technical Report outlines the proposed recovery methods for the Corner Bay-Devlin Property, owned by Doré Copper Mining Corp. The plan involves treating mineralized material from the Corner Bay and Devlin deposits at the existing Copper Rand Mill, located approximately eight kilometers southeast of Chibougamau. The mill has been non-operational since the end of 2008, and a comprehensive evaluation and repair program is required before a restart can occur.
The proposed process flow sheet details a multi-stage crushing circuit followed by grinding, gravity concentration, and flotation. The crushing circuit utilizes a jaw crusher as the primary unit, supported by standard and short head cone crushers in a closed circuit with vibrating screens. The crushed ore is then processed through a rod mill and ball mill circuit, incorporating primary and secondary Knelson concentrators for gravity recovery of gold and silver.
The flotation circuit employs Maxwell rougher tanks and Denver scavenger and cleaner banks to recover additional valuable minerals. The final concentrates are thickened, filtered using a filter press and disc filter, and stored. The report provides detailed equipment specifications and flow sheet descriptions, emphasizing the need for component evaluation and potential replacements to ensure the mill can be successfully restarted for production.
