The Buckeye (L.534) occurrence is located at an elevation of approximately 1220 metres on the western slope of Monte Cristo Mountain, north of the community of Rossland.

Regionally, the area is underlain by Lower Jurassic Elise Formation (Rossland Group) siltstone, argillite and hornfelsed siltstone, which is intruded by quartz monzonite of the Early Jurassic Rossland Plutonic Suite. The grey to black siltstone and argillite grades into hornfels and forms distinct layers within the volcanic breccias, and several horizons grade laterally into sandstone and breccia. Small Early Jurassic ammonitesare reported to occur in the siltstone on Ivanhoe Ridge. The Rossland Group rocks are crosscut by north-trending lamprophyre and diorite dikes hosting disseminated pyrite.

The Buckeye veins are part of the ‘North belt’ zone of discontinuous veins. On a regional scale, the veins appear to be continuous but in detail they are lenticular and offset by north-trending faults. The veins are hosted by the Early Jurassic Rossland monzonite, a biotite-hornblende-augite monzonite stock that is medium-grained, grey to green and hosts magnetite; apatite and some sphene chlorite, epidote, pyrite, and pyrrhotite. The stock intrudes siltstone, argillite, hornfels and volcanic conglomerate of the Lower Jurassic Elise Formation (Rossland Group).

Locally, two quartz and/or calcite veins, varying in width from 14 to 140 centimetres, host massive chalcopyrite, arsenopyrite and pyrrhotite.

In 1983, a chip sample (47178) from the adit assayed 22.2 grams per tonne gold, 31.5 grams per tonne silver and 3.07 per cent copper over 0.14 metre, whereas another chip sample (47184), taken a short distance north of the adit, yielded 21.0 grams per tonne gold, 7.2 grams per tonne silver and 0.30 per cent copper over 1.4 metres (Assessment Report 11846).

In 1986, a chip sample (16402E) from the adit yielded 5.3 grams per tonne gold over 0.2 metre, whereas two samples (83129 and 83130) taken from pits located approximately 200 metres to the east and northeast, respectively, yielded 0.68 and 2.19 grams per tonne gold with 0.60 and trace per cent copper, respectively (Assessment Report 15432).

The area has been explored since the late 1800s, with the Crown-granted mineral claims being staked in the early 1890s. Prior to 1915, approximately 170 metres of underground development work had been completed on the Buckeye (L.534) Crown grant.

In 1979, Cominco Ltd. completed a program of rock and soil sampling on the area. During 1982 through 1986, Gallant Gold Mines Ltd. completed programs of rock and silt sampling, geological mapping, ground geophysical surveys and seven diamond drill holes, totalling 694.0 metres, on the area as the Georgia property.

In 2018, Currie Rose Resources Inc. completed a 164.8 line-kilometre airborne magnetic survey on the area.
