The potentially mineable portion of the Revel Ridge Yellowjacket and Main Zone mineral resources extends along the strike length of the deposit for over 1 km, and over 800 m vertically from the 1310 Level to the 510 Level.
Currently, there is an exploration drift on the 830 Level, accessed by the 832 adit portal. There are also several other adits, none of which are anticipated to be used for mine traffic during mining operations but can be reopened and reinforced to provide secondary egress as required. Portions of the mine plan, above and below the 830 Level, are referred to as the upper and lower mine, respectively.
The stope shapes used were 20 m in height, 20 m in length and had a minimum stope design width of 2.5 m. The stope shapes also include an allowance for overbreak and include internal waste dilution.
The conceptual production mine plan produces an average 2,300 t/d of process feed for almost twelve years (11.96 years).
The first nine (9) years of the project focusses solely on mining the Main Zone, while years ten through twelve incorporate the mining of Yellowjacket Zone as well. The mining rate of 2,300 tonnes per day amounts to 839,500 tonnes per year, for a total of 10,039,384 tonnes over the 12-year mine life. The process feed from the Main Zone amounts to 9,392,872 tonnes, while the remaining 646,512 tonnes of process feed comes from Yellowjacket Zone.
The mine plan mines on 40 different levels from ........
