| Fonctions : | The diamond drill is used to retrieve core samples from the ground. The drill uses a rotating hollow diamond studded bit to retrieve cylindrical rock cores. The bits are encrusted with industrial grade diamonds, the hardest natural substance on earth, and they earn the drill its name. The drilling outfit consists of the drill itself, two small gasoline driven pumps, along with drill rods, core barrels, casing pipe and tools. Diamond drilling has become a very necessary part of the mining business. Miners use the drill to find out if sufficient ore exists in the ground and the depth of the overburden covering the ore. While the diamond drill is a versatile tool, its principal use is in the exploration and discovery of ore deposits. The drill is also useful for drilling blast holes in routine mining operations. Sometime prior to 1910, the government bought several drills which were lent free to miners for prospecting. One of the diamond drills ended up in the Mayo District and was left on Duncan Creek. This drill nicknamed the donkey drill was finally found on Silver Hill situated near the head of Ervin Creek in the upper Beaver area, the property was claimed by John McLean in the 1920s. In 1929, COMINCO diamond drilled on McKay Hill, they ran the drill off a 'Model A' Ford gas motor. In 1931, the drill and accessories were taken to Silver Hill and stored at the end of the season in a log shed. When the shed finally caved in 1995 a few men from the area went to investigate the ruins. They found the drill and flew it to Keno City. It took 10 trips by helicopter to move the drill.
