Production At Jerritt Canyon Operation

 

VANCOUVER - Yukon-Nevada Gold Corp. reported that two conveyors have been successfully installed to replace a problematic bucket elevator at its wholly-owned Jerritt Canyon gold processing facility in Elko County, Nevada. Jerritt Canyon is operated by Queenstake Resources USA Ltd., a wholly-owned subsidiary of Yukon-Nevada Gold Corp.

In July, a bucket elevator in the fine crushing unit was replaced with two conventional belt conveyors. The bucket elevator had been installed during the January 2012 shutdown, but caused significant plant downtime and could not reach design specifications due to persistent mechanical failure. The new conveyors were sourced from equipment inventory already at the site which significantly reduced costs. The conveyor installation was completed and has operated without a problem since that time. The conveyors have allowed crushing to operate at substantially over 300 tons per hour ("tph"), well in excess of the current 220 tph capacity of the ore roasters.

The operation produced and shipped 10,964 ounces of gold in July. This was achieved despite lower production throughput in the first eleven days of the month while a bypass screen and crushing plant operated during the switch-out of the bucket elevator to the new conveyors. The moderate under-performance of the temporary bypass crusher was due to equipment over-heating while running at full capacity. The new conveyors are operating very well and running above required capacity as planned.

Randy Reichert, Co-CEO and COO, commented, "Completion of the conveyor installation provides a permanent solution to the bottleneck in the fine crushing unit and represents the removal of the last remaining restriction to operating the mill at capacity as allowed by the Consent Decree (currently 5,280 tons per day). Our team at Jerritt Canyon did an excellent job removing the bucket elevator and installing the new conveyors in such a short period of time. This has allowed us to remain on track to meet planned production targets for 2012."

Mining at the SSX-Steer company-operated underground mine continues to ramp up production. During July 27, 300 tons were mined and the mine is on track to reach the production target of 1,200 tons per day in the third quarter of this year.  Smith mining continued to produce at the planned rate of 1,200 tons per day during the month of July.
