Goldcorp Red lake Gold Mines High Grade Zone

John Misiura, Senior Mine Exploration Geologist at Goldcorp Canada Ltd.

In 2008 and early 2009 TECH Directional Services were involved in the deep exploration program targeting the RLGM High Grade Zone from the 37 level of the Red lake Complex. Due to depth of drilling and accuracy required to reach our targets directional drilling was the method of choice to accomplish our goals.


Using a series of pre-existing drill holes, 15 holes totaling 24,794 feet of NQ size core were drilled in a period from May 2008 to April 2009. Accuracy ranged from 0 to 15 feet on average. The skilled TECH Directional team worked very closely with our geology staff and drilling contractor to make the program a success.


A change in exploration strategy in 2009 has eliminated the need for deep directional drilling. In the future however I would strongly consider TECH Directional Services should similar circumstances present themselves.
