Before hard rock mining operations even begin, companies explore areas where gold may be found and analyse the rock. If enough gold is discovered in the ore, the technological process of hard rock mining begins. ... The miners would cart the ore out of the mine in wheeled carts pushed on rails and take it to the mill. The gold milling process ...
Drilling performance data can provide a viable means of characterizing the rock mass for MTM. The use of blasthole drilling data is advantageous since it is acquired systematically, routinely, and in real time [9].In the mining industry, monitoring while drilling (MWD) is a standard practice for obtaining penetration rate (PR), rotational speed, …

First a short history: Gold was discovered on the property about 1916-18. Between 1938 and 1970, the Hardrock mine produced more than 2.0 million oz. as an underground mine. Premier Gold Mines acquired the project in 2008 and two years later, after completing additional exploration drilling, produced a resource estimate.
Hard Rock Miner's Handbook is a work of the heart.
