The RU occurrence is located just north of Surprise Lake about 23 kilometres northeast of the community of Atlin.
Coarse-grained, occasionally porphyritic, biotite quartz monzonite of the Late Cretaceous Surprise Lake batholith (Surprise Lake Plutonic Suite) is overlain by Neogene Tuya Formation alkaline volcanics. A basal flow of columnar olivine basalt, 10 to 15 metres thick, is overlain by an upper, vesicular volcanic fly ash and scoria unit, 20 to 40 metres thick. A paleochannel of gravel underlies the basalt unit.
The gravels are up to 6 metres thick and consist of three units. The basal gravel, up to 0.5 metres thick, immediately overlies the quartz monzonite and contains uranium values of up to 0.013 per cent. An unoxidized middle gravel, 1 to 4 metres thick, contains uranium values up to 0.0165 per cent. An oxidized upper gravel, immediately underlying the basalt, is represented by an exposure of a 10-centimetre-thick rusty semi-consolidated pebble conglomerate with 0.02 per cent uranium (Assessment Report 6923). The uranium is present as the oxide zeunerite.
The nearby alaskites of the batholith are the likely source of the uranium. See also Ruby Creek placer occurrence (104N 028) located 430 metres north, for placer gold information.
In 1978, prospecting, sampling, and mapping was conducted on behalf of Granville Square Joint Venture.
In 2002, prospection was done by William B Wallis on the B&B and B&W 1&2 claims, who is the owner of these claims as well.
In 2016, two holes were drilled by Global Drilling Solutions on behalf of Zinex Mining Corporation on the Ruby Creek Property, targeting native gold.
In 2017, Global conducted extensive geochemical sampling on this property, as well as further drilling and ground geophysics. In 2018, Global carried out further geochemical sampling on the property, and in 2019 they continued work in this region, in the form of prospection, geochemical surveying and a ground geophysical survey.
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.
