In 1916, due to war associated tungsten shortages, an exploration and development program was initiated, which outlined a tintungsten stockwork suitable for opencast extraction. In 1917, Hemerdon Mines Ltd decided to construct a 140,000tonne per year mill, and shortly afterwards opencast ore mining operations began.
Open pit mines exist but are rare. Tungsten mines are relatively small and rarely produce more than 2000t of ore per day. Mining methods for tungsten ore are not at all exceptional and usually are adapted to the geology of the ore deposit. Most tungsten ores contain less than % WO 3 and frequently only a few tenths of a percent.
Open pit mines may be circular, like the ones shown pictured at the Ekati mine, or oblong, and include several mining levels know as benches. Roads, known as ramps, allow access to the orebody. The size and depth of an open pit is a balance of how much worthless waste rock must be mined to gain access to the valuable ore.
