Copperstone Project Pitch
2021 - Key Project Achievements
Optimization
Detailed Engineering
Final Engineering - Secured several key Engineering Groups to advance backfill design, geotechnical, ventilation, water
management and electrical infrastructure.
➤ Backfill & Ground Control - Geotechnical studies have indicated wider mining widths and strength of backfill using mine
development materials which will further enhance previously estimated production efficiencies.
➤ Mine Engineering - Final mine design mine design and schedules are underway. Considerations in the design and schedule
include optimizing work-flows and implementing newly identified advantages related to ore sequencing, production efficiencies
and haul profiles.
➤ Mine Operations - Initiated pre-production mine ground support rehabilitation and commenced stope definition drilling for
detailed final gold ore stope designs.
➤ Mineral Processing Plant – Engineering well advanced for final layout and design of WOL gold processing plant. Final costing
for crush and grind circuit and receipt of quotations for longer lead equipment. Final metallurgical testing nearing completion.
to optimize grind size, leach kinetics and reagent consumption.
