Queenstake Resources (QRL-T) has cut high gold grades combined with impressive widths at its Starvation Canyon project, 12 miles southwest of its Jerritt Canyon mill in Nevada, U.S.A.
Reverse circulation drilling resulted in intercepts as wide as 95 ft grading 0.4 oz. per ton. In another hole 80-feet graded 0.3 oz. per ton and two holes cut 60-ft-intercepts, one grading 0.42 oz. per ton and another 0.33 oz. per ton.
Fifty-eight holes were drilled (totaling 45,000 ft). Twenty holes cut grades of at least 0.15 oz. per ton over widths of 5-95 ft. Apart from the four holes listed above, five holes cut grades of 0.3-0.45 oz. per ton over 10-40 ft.
The Starvation Canyon area has been tested over a 2,000-ft strike length. It is still open along strike. The mineralized zone is between 200-400 ft wide and strikes northwest. It is crosscut at right angles by numerous faults.
Gold enrichment is found in pods at the intersection between northwest and northeast structures, particularly within specific stratigraphic units. Northwest structures often host mafic dykes.
High-grade gold is associated with carbonate alteration and local argillization and silicification. Geological mapping and geochemical sampling have been carried out along the known mineralized trends to help target further drilling.
The zone is in an area of steep topography, above the canyon floor. The company is hopeful that the mineralized zone will continue to follow the same northwest trending structure that can be traced over a distance of at least 4.5 miles.
The Jerritt Canyon property encompasses 100 sq. miles and hosts four producing underground mines that provide feed for one milling facility.
As at the end of December of last year, the proven and probable reserves are estimated at 2.6 million tons with a grade of 0.30 oz. per ton.
