Work to update the 2018 Feasibility Study (FS) at TSX listed Orezone Gold Corporation’s Bomboré project in Burkina Faso is underway.
The updated study will include a staged higher-grade sulphide expansion (Phase II Sulphide Expansion) to complement the oxide mine plan in the 2018 FS.
The Phase II Sulphide Expansion is envisioned as a 3 000 to 3 500 tonne per day (tpd) sulphide circuit to process zones of higher-grade sulphide and lower transition oxide resources starting in the third year of commercial production. According to Patrick Downey, president and CEO of Orezone, capital for the expansion will be funded by future operating cash flows.
Bomboré is currently being designed as a 5.2 million tonne per annum (Mtpa) operation and is advancing through detailed engineering with first gold production scheduled to commence by October 2020.
“The sulphides at Bomboré has always been viewed as a large low-grade deposit. However, a recent detailed review of the measured and indicated (M&I) sulphide resources by Orezone and our consultants has identified continuous zones of significantly higher grade, near surface mineralisation which warrants a more in-depth analysis.
“In addition to the higher grade sulphides at P17S, we have successfully identified four additional areas of thick and continuous higher-grade M&I sulphide resources located directly beneath current oxide reserves. Historical metallurgical test work together with pit geotechnical evaluations have been previously completed on these sulphides which will allow for rapid advancement of this update that is due for completion by the end of quarter two in 2019,” says Downey.
