DENVER, Aug. 3 /PRNewswire-FirstCall/ -- A recently completed surface drill hole by Queenstake Resources Ltd. (TSX: QRL; Amex: QEE) at the Starvation Canyon project identified one of the best intervals of high-grade gold mineralization in the history of Jerritt Canyon exploration: 140 feet with an average grade of 0.46 ounce of gold per ton (opt) or 43 meters of 16 grams of gold per tonne (gpt), beginning at 280 feet (85 meters) from surface. This interval includes an intercept of 70 feet of 0.63 opt (21 meters of 22 gpt), which in turn includes 40 feet of 0.87 opt (12 meters of 30 gpt). Commenting on this exploration result, President and Chief Executive Officer Dorian L. (Dusty) Nicol said, "This exciting discovery of additional high-grade gold mineralization at Starvation Canyon is significant due to its location, as much as its thickness and grade. The 140-foot interval at 0.46 opt is located between the two known gold resource zones and could represent a newly identified northwest trending gold-bearing structure. It is also considerably higher grade than our Starvation Canyon estimated measured and indicated resources of 676,400 tons at 0.28 opt (190,700 contained ounces). We are following up with additional step-out drilling intended to extend the west zone of Starvation Canyon." Starvation Canyon's gold resources are contained in two northwest trending zones (see the Appendix: Map 1), which currently extend 1,700 feet (518 meters) and are open in several directions. The currently defined resource is within a prospective 4.5-mile (7.2 kilometer) corridor of gold occurrences in favorable geologic settings. This trend appears comparable geologically and geochemically to the mineralized trends in the northern and central parts of the Jerritt Canyon district that have combined to produce over 7.5 million ounces of gold since 1981. Two reverse-circulation rigs are drilling at the project, with a core rig expected to be added to the program later this year. Queenstake expects to invest $3 million in exploration at Starvation Canyon in 2006. The project is located on Queenstake's private land, approximately 12 miles southwest of the Jerritt Canyon mill. The Starvation Canyon deposit lies above the water table in an area of steep topography and could be easily accessed by development of a drift from the hillside. Evaluation of Starvation Canyon Exploration Drift Mr. Nicol added, "With a very large area of favorable geology for exploration drilling, we are optimistic about resource additions at Starvation Canyon and advancing the project to production within the next two years. We are currently evaluating development of an exploration drift that could more rapidly advance the project from underground drill platforms. Preliminary designs indicate that an 800-foot drift would reach the known boundary of the west zone. We expect to make a decision regarding the exploration drift in the fourth quarter of 2006." The exploration results(1) from surface reverse circulation drilling in the west zone described in this news release are outside of the boundary of estimated resources(2) identified at year-end 2005 (refer to the March 5, 2006 news release announcing estimated mineral reserves(2) and resources). The table below provides highlights from a completed drilling campaign of three 500-foot (152-meter) holes in the west zone of Starvation Canyon. Drill hole TJ-248 was approximately 80 feet east of the eastern boundary of the West Zone at Starvation Canyon and drill hole TJ-246 was approximately 300 feet (91 meters) west of TJ-248.

Drill testing of some prospective targets at Starvation Canyon has been hampered this year by a lack of sample recovery at the targeted depths using reverse circulation drilling. Testing of these areas awaits the arrival of a core drilling rig. Queenstake Resources Ltd. is a gold mining and exploration company based in Denver, Colorado. Its principal asset is the wholly owned Jerritt Canyon gold operations in Nevada. Jerritt Canyon has produced over 7.5 million ounces of gold from open pit and underground mines since 1981.
