Pine Cove mines small zones of ore—increasing overall recovered tonnes
Garry Luffman, senior geologist at Anaconda Mining’s Pine Cove mine, describes how the geology team use BMT’s blast movement monitor system to recover narrow ore zones.
Without BMT, Anaconda would not attempt to recover these small polygons due to movement.
Located in Newfoundland, Pine Cove mine is a surface gold mining operation with structurally controlled deposits containing very irregular ore zones, with both narrow and wide zones within. While there is a main section to the deposit, there are many thin zones on the fringes of the deposit.
The thin areas experienced high dilution, over 20%, which resulted in lower feed grades through the mill. Using the BMM System, Pine Cove has reduced dilution to 5%, increased the grade and limited the waste going to the mill: realising US$15,000 to $30,000 dollars per blast.
