Description:
The Pogo gold mine, located southeast of Fairbanks, Alaska, is an
underground mine with annual gold production of 350,000 to 450,000
ounces over its projected 10 year life. The mine area is located
in a zone of discontinuous permafrost and the 50 mile road constructed
to the mine site crosses a large aeolian sand dune formation.
Teck Cominco has a 40% interest in the mine and is the operator.
The other partners are Sumitomo Metal Mining Co. Ltd. (51%) and
Sumitomo Corporation of Japan (9%).
At the site there is a permanent camp for 300 people, gold processing
facilities, water treatment plant and paste backfill plant/dry-stack
tailings facility. Mining methods are cut and fill and drift and
fill. The mill utilizes conventional milling and gravity and carbon-in-pulp
technology. Gold from both the gravity and carbon-in-pulp circuits
is produced as dore bullion, which is sent to the U.S.A. for refining
and sold to third parties.
