Executive Summary
This NI 43-101 Technical Report details the recovery methods for the Sainsoutou Property, part of the Birima Project. The deposit is identified as a placer deposit containing gold that has been naturally concentrated and freed by weathering. Consequently, the mining process does not require blasting, crushing, or grinding, distinguishing it from hard rock operations.
The recommended processing plan relies exclusively on gravimetric concentration. The ore consists of free nuggets in gravel sediments, allowing for a cost-effective gold recovery solution using gravity circuits. The process involves screening to remove large rocks, washing to separate gravel and sand, and gravity separation equipment to recover the gold. No chemical treatment is required during processing.
Recovery tests indicate an estimated gold recovery rate of 90 to 95% using gravimetric concentration. The recommended equipment includes a gold washing trommel, sluice boxes, shaking tables, and centrifugal concentrators. This approach is designed to handle the specific granulometric characteristics of the gravel material at Sainsoutou, which has low clay content.
