Silver Range Resources - Stinson Property
Aurora Geosciences completed a mapping and prospecting program.
The Stinson Project consists of 14 claims located in White Pine County, approximately 35 kilometres north of Ely. The claims cover MRDS showings M031255 (Stinson Mine) and M233767 (Old West Group). The latter appears to be the location of the Ben Hur Mine based on the extensive workings at the site and historical descriptions of its location. Gold occurrences at the Stinson and Ben Hur Mines may be part of a much larger structurally-controlled hydrothermal system. The gold occurrences on the Stinson Property together with six other MRDS showings are associated with north-striking faults and contacts in a 7 kilometre long, north-trending corridor. This terminates in the Steptoe Ranch Pluton, 3 kilometres north of the Stinson Property. Video presentation available here.
At the Stinson Mine, gold occurs with quartz veins in a southwest striking, moderately east dipping shear zone in Ordovician to Silurian carbonates. Sampling at Stinson during 2016 returned best results of 6.94 g/t Au from a grab sample and 3.8 m @ 2.57 g/t Au including 1.6m @ 8.16 g/t Au in a chip sample across the shear zone. Three of 15 samples collected at Stinson returned more than 1 g/t Au.
At the Ben Hur Mine, work in 2016 and 2017 defined a north striking, gently east dipping shear zone with quartz veining and hematite alteration cutting Cambrian quartzite. The shear has been traced for approximately 100 metres on surface and was intersected in underground workings 40 m down dip from the surface exposure. Surface grab sampling returned up to 248 g/t Au with 7 of 27 samples collected at Ben Hur returning greater than 1 g/t Au. A chip sample across exposed surface mineralization near the highest grade grab sample returned 1.5 m @ 20.6 g/t Au. Grab samples from dump material at workings along the vein 50 metres southwest and northeast of this location returned 5.97 g/t Au and 5.15 g/t Aurespectively. The shear zone is exposed underground in a cross-cut 40 metres east and down-dip of the surface exposures. Chip sampling of the partially exposed vein here returned 0.4 m @ 3.58 g/t Au. The crew was unable to sample mineralization in the production stopes because of poor ground conditions. A plan map and cross section showing sample locations and results can be found here.
