The Goldstrike Mine consists of operating open pit and underground mines.
The Betze-Post open pit is a truck and shovel operation. With completion of the 3rd NW phase targeted for March 2019, the open pit has three remaining phases (4th NW, West Barrel, and 5th NW). The ultimate pit will measure approximately two miles east to west, 1.5 miles north to south, and have an average depth of approximately 1,300 ft.
The underground mine consists of 11 separate production areas stretching over a length of 12,000 ft, and a vertical distance from approximately 600 ft to 2,000 ft below surface. At the southern end of the underground zones, the pit workings cut the underground zones.
SHAFTS
There are two access shafts for the mine - the Meikle shaft and the Rodeo shaft. Both are used for personnel and materials, while, ore is only hoisted via the Meikle shaft. The Meikle shaft is approximately 1,800 ft deep, extending to the 3,700 ft level, while the Rodeo shaft is 1,300 ft deep and extends to the 4,100 ft level.
Hoist operation in both shafts is automated with human oversight provided. There are ventilation shafts and boreholes for ventilation in both the Meikle and Rodeo mines.
RAMPS
There are three ramps to surface, all three are accessed through the open pit. The Betze No. 1 portal is a fresh air intake and used for both vehicular traffic and movement of ore to the pit. The Betze No. 2 portal is an emergency exit and ........
