At the Reliance occurrence, the mineralization occurs in northeast striking, steeply northwest dipping shear zones in green and purple volcanics and cherts of the Mississippian to Jurassic Bridge River Complex (Group). The old Reliance adit at 1100 metres elevation on Lot 7657, exposes a 2-metre wide oxidized shear zone in purple volcanics; an opencut above the adit contains 2.5 to 5-centimetre wide stibnite stringers in a calcite gangue. The Fergusson adit at 1023 metres elevation on Lot 7657, strikes east-northeast in sheared greenstone and contains a 15-centimetre wide stibnite vein in calcite and quartz with finely disseminated sulphides. A fault (also mineralized) cuts the shear after which the stibnite runs out in stringers. A 4-tonne shipment of the "richest" antimony ore is believed to have been made from the Fergusson adit in 1915, grading $10.40 gold. It is reported to have come from where a narrow tongue of diorite porphyry briefly follows the fault. The Turner adit (830 metres elevation on Lot 7659) strikes southeast following a 1.5-metre wide shear in silicified and pyritized green and purple volcanics containing stibnite veinlets and disseminated sulphides. The River adit (663 metres elevation on Lot 7660) is a crosscut to the Turner adit.

The Reliance gold property mineralization occurs as intermediate temperature gold-silver epithermal-mesothermal quartz-carbonate-pyrite stibnite-arsenopyrite-fieibergite veins within replacement ankeritic alteration related to one or more major shear zones.

The Royal shear zone hosts six showings: Diplomat, Senator, Imperial, Merit, Crown and Eagle, with each showing probably representing a pipe. The Imperial showing is the upper part of a mineralized pipe, an ellipse 30 metres long by 15 metres thick at the widest point, which plunges in a westerly direction from 50 to 70 degrees. The Crown showing, located 300 metres south and 130 metres higher in elevation than the Imperial showing, is the location of a second pipe with the same geology and erratic values as the upper part of the Imperial pipe.

The Royal shear zone is the main alteration-mineralization-shear zone and the main known mineralized portion of the Royal shear zone is called the Imperial zone. The Imperial zone has a mainly basaltic volcanic footwall and a sedimentary argillite and chert hanging wall. Overall, the Imperial gold zone is up to 80 metres or more in true width, strikes northwest and dips about 40 degrees southwest. The northwest strike and southwest 40 dip of the Imperial-Royal shear zone projects to lower elevations in the northwest corner of Claim 7651 and to higher elevations in the southern end of Claim 7498. The extensions of the zone are covered by overburden.

Proven and drill indicated reserves are 410,916 tonnes grading 5.96 grams per tonne gold (George Cross News Letter April 14, 1988).

The property consists of 19 reverted Crown-granted mineral claims and fractions including the Nemo, Omen and Eros claim groups. Its history was noted by Caimes (1943): "The Reliance is one of the older properties and has been known from the beginning as an antimony prospect. The original group of four claims was staked in 1910 by Mr. F. A Brewer, who relocated the property in 1915. By September 1915, it is reported, four tons of ore had been bagged for shipment, and the richest carried up to 1/2 ounce in gold a ton (17 grams per tonne gold).

In 1917 there was a shipment of hand-cobbed gold-bearing stibnite but no further records are available for this period. The property was reorganized by Reliance Gold Mines Limited in 1933 and development work continued until 1937. This included underground work on several adits and installation of a compressor plant. The mine workings comprised the old Reliance adit (elevation 1100 m) on the Nemo 7 Crown-granted claim; the Fergusson adit (elevation 1023 m) also on Nemo 7; the Turner adit (elevation 830 m) on Omen 1; the River adit (elevation 663 m) on Omen 2; and the Senator adit (elevation. about 790 m) on Nemo 1. Short intervals of heavy stibnite mineralization in narrow quartz veins were encountered in the adits. In 1971, Tri-Con Exploration Survey Limited carried out geotechnical surveys for T.V.I. Mining Limited outlining several electromagnetic conductors coincident with a prominent southeast -trending arsenic-antimony geochemical anomaly near the Senator workings on the west part of the property.

Menika Mining in 1984 acquired the Reliance gold property by option agreement from Karl Otting of Lillooet. Five 1985 diamond drill holes were reported on by L. Sookochoff in "Diamond Drill Report for Menika Mining", dated February 10,1986. A “discovery” hole, drilled in 1986, was drilled to a depth of 119 metres. During 1987, an extensive drilling program comprising 8,476 metres of drilling in 53 diamond drill holes was carried out. The 1988 program consisted of 3294 metres of drilling in 23 diamond drill holes. The locations of only a few of these drill holes are known to Menika Mining. There was a lapse in exploration activity until 1996 when another program consisting of 13 drill holes was carried out.

In 2003, Menika Mining Ltd conducted limited surface sampling on the Reliance property with encouraging results. They followed up in 2004 with three diamond drill holes with encouraging results, such as 33.5 metres grading 7.54 grams per tonne gold (Exploration and Mining in BC 2004, page 59).
