The Elanore (L.951) occurrence is located near a saddle on a ridge to the north of Monte Cristo Mountain at an elevation of approximately 1200 metres.
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 Elanore vein(s) are part of the ‘North belt’ zone of discontinuous veins. On a regional scale, the vein(s) appears to be continuous but in detail they are lenticular and offset by north-trending faults. The vein(s) are hosted by Lower Jurassic Elise Formation (Rossland Group) siltstone, argillite, hornfelsic siltstone and augite porphyry volcanics. The hornfelsed siltstone is due to thermal metamorphism related to quartz monzonite of the Early Jurassic Rossland Plutonic Suite to the south and the Middle Jurassic Trail Pluton to the north.
Mineralization consists of a mineralized shear zone, up to 3.0 metres wide, generally striking 020 degrees and dipping 55 degrees west and hosted in primarily an augite porphyry volcanic. The shear zone hosts quartz veins and veinlets with massive stringers and pods of pyrrhotite, arsenopyrite and minor chalcopyrite. The volcanic host is cut by a 3.0-metre wide feldspar porphyry dike. Fine-grained visible gold has been reported from a ‘decayed’ (oxidized?) sulphide vein.
Another area of former workings, located near the northwest corner of the Viking (L.4916) Crown grant to the northeast, comprise an adit and former trenches exposing a quartz vein or veins, up to 0.35 metre wide, in a silicified granodiorite. Mineralization comprises pyrite, chalcopyrite and galena. Chlorite is also reported to be associated with the veins.
In 1983, a dump sample from the Viking (L.4916) area adit yielded 0.2 gram per tonne gold and 10.9 grams per tonne silver (Assessment Report 11846).
In 1994, surface samples are reported to have yielded up to 249.7 grams per tonne gold (Assessment Report 25363).
In 2009, outcrop samples from the Elanore (L.951) Crown grant yielded up to 110.02 grams per tonne gold, 5.5 grams per tonne silver, 0.395 per cent copper, 0.346 per cent cobalt, 0.164 per cent bismuth, 0.056 per cent tungsten and 0.067 per cent nickel (Assessment Report 31127).
The area has been explored since the late 1800s, with the Crown-granted mineral claims being staked in the 1890s. Development work dating to this time included numerous trenches, a 17-metre long adit and at least two shafts on the Elanore (L.951) Crown grant, with other workings reported to the northeast, near the northwest corner of the Viking (L.4916) Crown grant.
In 1967, Thorpe described mineralization north of Monte Cristo (MINFILE 082FSW101) as hosting native gold and bismuth associated with arsenopyrite and magnetite in the Intermediate zone. 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. This work identified a dump containing approximately 1360 tonnes of ore of an unknown grade.
In 1994, Pacific Vangold Mines Ltd. completed three diamond drill holes, totalling 216.6 metres on the area. In 2009, the area was prospected and sampled as the Crown of Eleanor claims. In 2016 and 2017, further programs of prospecting and rock sampling were performed. In 2018, Currie Rose Resources Inc. completed a 164.8 line-kilometre airborne magnetic survey on the area.
