Mining’s old guard needs strong medicine
A new report details subpar investor returns in the mining industry over the last decade, particularly big cap diversified companies which have not adapted to new realities.
The second phase of the scout drilling program at Ridgeline Minerals’ wholly owned, 26-sq.-km Selena project in Nevada, 64 km north of Ely, hit shallow oxide gold-silver mineralization at the Chinchilla and Juniper targets.
The company has released assay results for 10 reverse circulation drill holes. The drill highlights include 29 metres of 0.38 g/t gold and 65.28 g/t silver (1.26 g/t gold-equivalent) starting at 126.5 metres in hole SE20-014; 9.1 metres of 0.36 g/t gold and 78.28 g/t silver (1.42 g/t gold-equivalent) from 118.9 metres in hole SE20-013; as well as 21.3 metres of 0.3 g/t gold and 15.58 g/t silver (0.51 g/t gold-equivalent) from 91.4 metres in hole SE20-006.
“Our 2020 drilling campaign represents the first new drillholes at Selena in decades with results to date indicating we are in the early stages of an emerging shallow oxide, gold-silver discovery,” Mike Harp, Ridgeline’s VP of exploration, said in a release.
Harp added that the company remains encouraged by the widespread mineralization from the second-phase drill program and that, as its understanding of the geologic model at Selena has evolved, Ridgeline has hit “progressively wider and higher-grade mineralized intercepts.”
A third-phase, 1,500-metre drill program is now scheduled for October, to follow up on the latest intercepts and test additional fault zones between Chinchilla and Juniper, which are coincident with gold-silver and Carlin-type pathfinder soil anomalies.
According to Ridgeline, holes SE20-013 and SE20-014 hit some of the strongest mineralized intercepts to date from Selena and were the first holes to directly intersect the Juniper fault zone, which forms part of a corridor connecting the two targets tested. The third-phase program will target gold-silver mineralization at the intersection of fault zones interpreted as the feeder zones for the Selena mineralizing system.
Cyanide shake tests completed on drill assays of over 0.2 g/t gold suggest average cyanide solubilities of 81% and 74% for gold and silver, respectively. The initial results suggest that the Selena mineralization may be suitable for heap leach processing.
In addition to Selena, Ridgeline wholly owns the 39-sq.-km Carlin East and 51-sq.-km Swift projects in Nevada.
