The Ruby Creek (Molly Lake Silver) occurrence is located at an elevation of approximately 1630 metres on an east-west–trending ridge, southwest of Molly Lake and approximately 1.2 kilometres east-southeast of Mount Leonard.

The area is underlain by the contact of the Jurassic Fourth of July Creek Batholith and the Mount Leonard boss. The Mount Leonard boss is the west part of the Late Cretaceous Surprise Lake Batholith (Surprise Lake Plutonic Suite) but is separated from the main batholith by a pendant of Mississippian to Triassic Cache Creek Complex rocks. The Fourth of July Batholith is a fairly uniform, medium-grained, biotite-hornblende diorite to granodiorite. In the occurrence area the Mount Leonard boss is composed of quartz monzonite.

Locally, diamond drilling has intercepted gold and silver values. The rock types and style of mineralization intercepted were not reported.

In 2016, diamond drill holes ADV2-2016-004 and -005 yielded intercepts of 3.528 and 2.249 grams per tonne gold with 1500 and 758 grams per tonne silver over 0.15 and 1.53 metres (54.56 to 54.71 and 55.47 to 57.00 metres down hole), respectively, whereas two historical drillholes (AD-381 and AD-408) in the same area are reported to have yielded 0.40 and 0.29 gram per tonne gold with 50.3 and 87.5 grams per tonne silver over 3.05 and 24.4 metres (236.22 to 239.27 and 62.48 to 86.87 metres down hole), respectively (Aspinall, N.C. [2019-10-22]: Technical Report on the Ruby Creek Project Within the Atlin Gold Camp, British Columbia, Canada).

Work History

The area has been explored in conjunction with the nearby Adanac Molybdenum (MINFILE 104N 052) mine and a complete regional exploration history can be found there.

During 2016 through 2018, Global Drilling, on the behalf of Stuhini Exploration Ltd., completed programs of prospecting, geochemical (rock and soil) sampling and 14 diamond drill holes on the area as part of the Ruby Creek project.
