The Georgia (L.928) occurrence is located at an elevation of approximately 1180 metres on the southeastern side of Monte Cristo Mountain and 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 ammonites are 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 Georgia vein system consists of at least 12 individual veins and lies within the siltstone near the monzonite contact. Mineralization is part of the eastern extension of the Main vein system, and consists mainly of pyrrhotite and chalcopyrite with minor pyrite in quartz-calcite gangue. The best grades of mineralization were obtained along steeply dipping east-west veins, where grades consistently ranged between 5.14 to 8.6 grams per tonne gold over widths of 1.5 to 3.0 metres (Assessment Report 11846). Refer to the Le Roi (MINFILE 82FSW093) deposit for further details on the Rossland camp and the Main vein system.

In 1980, percussion drilling on a 200 by 100 metre area containing east-west–dipping veins of the main Georgia vein yielded intercepts with up to 1.606 grams per tonne gold over 18.0 metres, including 9.7 grams per tonne gold over 3.0 metres, in hole GP-80-8; 0.201 gram per tonne gold over 75.0 metres in hole GP-80-9 and 0.312 gram per tonne gold over 72.0 metres in hole GP-80-10 (Assessment Report 7868).

In 1982, a 1.2-metre chip sample taken across vein 11, where it was exposed in adit No.3, assayed 1.23 grams per tonne gold, whereas a second 1.2 metre sample taken across barren wallrock assayed 0.75 grams per tonne gold (Assessment Report 11846).

In 1983, three chip samples (47160, 47182 and 47292) assayed 8.5, 18.1 and 5.5 grams per tonne gold and 4.1, 7.5 and 2.7 grams per tonne silver with 0.26, 0.70 and 0.13 per cent copper over 0.25, 0.30 and 0.35 metre, respectively (Assessment Report 11846).

In 1986, a chip sample (997E) of a series of veins in silicified granodiorite from the Georgia No.1 tunnel yielded 3.8 grams per tonne gold over 0.3 metre, whereas a diamond drill hole (G86.4) yielded intercepts up to 4.5 grams per tonne gold over 0.7 metre of massive pyrrhotite vein (Assessment Report 15432).

Intermittent production over 4 years during 1933 through 1939 resulted in 49 tonnes of ore yielded 466 grams gold and 653 grams silver. In 1940, drill-indicated reserves were reported at 34 927 tonnes grading 7.80 grams per tonne gold from the 11, 11A and 12 veins (Assessment Report 11846).

In 1995, proven reserves for the Georgia property were reported at 48 983 tonnes grading 7.88 grams per tonne gold (George Cross News Letter No.139 [July 20], 1995).

The area has been explored since the late 1800s, with the Georgia (L.928) Crown-granted mineral claim being staked in the 1893. During 1893 through 1897, a series of trenches, shafts and two adits were developed on the Crown grant.

During 1937 through 1941, Gold Cup Mining Co. Ltd. completed programs of trenching and diamond drilling with underground development and production occurring on three levels.

In 1979, Cominco Ltd. completed a program of rock and soil sampling on the area. The following year, 16 percussion drill holes, totalling 705 metres, were completed.

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 2015 and 2018, Vangold Resources Ltd. completed minor programs of soil sampling and geological mapping on the area.
