The Purple Rose occurrence is located at the headwaters of Cracker Creek which drains eastward into the north end of Surprise Lake, about 24 kilometres northeast of the community of Atlin.

The primary lithology in the area is that of a coarse grained to porphyritic alaskite to quartz monzonite belonging to the Late Cretaceous Surprise Lake batholith (Surprise Lake Plutonic Suite). These rocks have intruded sedimentary sequences, composed of quartzite and limestone, of the Mississippian to Triassic Kedahda Formation (Cache Creek Complex), and greenstone of the Upper Mississippian to Permian Nakina Formation (Cache Creek Complex). Upper Mississippian to Permian Cache Creek Complex variably serpentinized ultramafic rocks (peridotite) have also been intruded by the Surprise Lake batholith in the Cracker Creek area.

The showing is associated with a northwest trending shear zone that is near the boundary of, but hosted entirely within, the alaskite to quartz monzonite body, near its contact with the sediments. The shear zone and associated mineralization has been traced over 500 metres. The alaskite is strongly "kaolinized" near the shear zone and the degree of alteration decreases away from the shear. Within the strongly altered alaskite, on the footwall of the shear zone, the uranium mineral zeunerite is found. This zone yielded the highest values of 0.075 per cent uranium and 0.011 per cent thorium oxide. Other minerals associated with the zeunerite are autunite, arsenopyrite, tetrahedrite, pyrite, galena, minor fluorite and vuggy quartz. One sample also assayed 1.06 per cent copper (Minister of Mines Annual Report 1955, pages 7 to 9).

In another area where the alaskite body comes in direct contact with limestone, the limestone is metamorphosed to a tremolite-garnet skarn with patchy magnetite and copper staining of malachite and azurite.

In 1954, the Purple Rose and Fisher claim groups were located to cover uranium showings discovered by O. Olsen and N. Fisher, of Atlin, while prospecting for K.J. Springer, of Toronto. During the summer of 1955, Barymin Company Limited completed surface stripping on showings on both groups.

In 1976, Union Oil Company of Canada Limited conducted prospecting, completed a scintillometer survey and collected rock - and silt samples.

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 2017, Global Drilling Solutions on behalf of Zinex Mining Corporation conducted extensive geochemical sampling on the Ruby Creek property, as well as 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. Rock sample 1893052 returned 0.22 grams per tonne gold, 7.4 grams per tonne silver, 0.007 per cent copper, 0.14 per cent lead and 0.07 per cent zinc (Assessment Report 39048).

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.
