The Fisher occurrence is located on Mount Leonard about 21 kilometres northeast of the community of Atlin.

Quartz monzonite and alaskite of the Late Cretaceous Surprise Lake batholith (Surprise Lake Plutonic Suite) intrudes the Upper Paleozoic Cache Creek Complex consisting of argillite, quartzite, and limestone and Upper Mississippian to Permian Cache Creek Complex mafic rocks enclosed in ultramafic masses of serpentinized peridotite.

Two northeast striking mineralized shear zones occur in kaolinized alaskite. Minerals include arsenopyrite, wolframite, pyrite, tetrahedrite, and zeunerite. A selected sample assayed 0.064 per cent uranium and 0.66 per cent copper (Minister of Mines Annual Report 1955).

In 2002, geological, geochemical, and geophysical surveys were carried out on the Adanac claim group by Stirrup Creek Gold Ltd. A report was prepared by A. Kikauka on behalf of Stirrup, describing economically significant base and precious metal mineralization.

In 2006, Adanac Molybdenum Corporation conducted a diamond-drill program on the Adanac/Ruby Creek ‘porphyry molybdenum’ property, the samples of which were submitted for molybdenum and/or trace element analysis. In 2007/2008, Adanac Molybdenum conducted further drilling in the property.

Global Drilling Solutions Inc. acquired the majority of the claims comprising the current Ruby Creek Project in the spring of 2016 from Adanac Moly Corporation. In 2017, Global conducted geochemical sampling, drilling and ground geophysics on the Ruby Creek property. In 2018, Global carried out further geochemical sampling and drilling on this property. It’s mentioned that the Ruby Creek property remains of high interest for not only gold/molybdenum but also for silver and copper based on the exploration work during during 2017/2018 (Assessment Report 38256).

In 2021, an airborne SkyTEM survey was conducted by Stuhini Exploration on the Ruby Creek property, which revealed a number of regional trends across the property.
