To-date, GRC made significant progress in resuming the Mine and Mill Operations at the Siana Mine. Key milestones were achieved in terms of Mines, Process Plant and TSF construction.
The Process Plant was successfully commissioned last December 2022 ahead of its planned schedule. The plant milled 48,459 tonnes of ore with an average grade of 0.87 g/t Au and 3.44 g/t Ag. As of February 2023, 62.3 kilograms of dor containing 896 oz of Au have been smelted and a total of 83.3 kilograms of dor containing 1,229 oz of Au have been shipped.
At the Mines, 8.01Mt of material have been moved and is currently within schedule to reach the main ore body by the 1st half of 2024. Slope stability measures are likewise in place to support mine operations.
Also as of February 2023, an additional 5,615 tonnes of ore averaging at 1.40 g/t Au were produced and delivered to the ROM pad where a build-up of medium and high-grade ore stockpiles is ready for blending options with low grade stockpiles.
The construction of TSF-6 has made significant headway and is expected to be fully complete by April 2023 while hydrotesting of the pipelines from the Process Plant to TSF-6 have been successfully completed. In March 2023, TSF-6 was commissioned and is now currently containing the tailings discharge from the Process Plant..
