The Fire Creek prospect occurs along the northeast side of Fire Creek, 1.5 kilometres west-northwest of the confluence with the Lillooet River.

A zone of strong sericitic alteration, chalcedonic silicification and heavy pyritization is developed in interbedded andesitic tuff, feldspar crystal tuff and sericite-chlorite schist. The sequence is part of the lower member of the Early Cretaceous Brokenback Hill Formation, Fire Lake Group. Information based on drilling indicates that the alteration zone strikes northwest for 200 metres and dips steeply northeast to depths of greater than 120 metres. True thicknesses vary from 20 to 40 metres.

Mineralization consists of 20 to 40 per cent disseminated and stringer sulphides, with veins up to 20 centimetres in width. Sulphides consist mainly of pyrite and pyrrhotite, minor chalcopyrite, sphalerite and arsenopyrite, and trace bornite, acanthite, pyrargyrite and native copper. Less altered lithologies around the periphery of the zone contain up to 15 per cent in disseminated and bedded sulphides, which mainly comprise pyrite, pyrrhotite and minor chalcopyrite. The alteration zone is cored by a hydrothermal breccia exhibiting intense argillic-potassic clay alteration, containing 20 to 40 per cent disseminated and stringer pyrite. Quartz veins, up to 50 centimetres in width and containing less than 5 per cent sulphides, are found throughout the alteration zone. A chip sample taken across 2 metres contained 10 grams per tonne gold (George Cross News Letter #26, 1988).

The occurrence was discovered in 1980 after rusty pyritic boulders were seen in Fire Creek.

In 1981, Territorial Gold Placers Ltd. collected 159 rock, silt and soil samples, which outline a zone of anomalous gold, arsenic, silver, barium and lead approximately 1000 by 300 metres wide and 70 metres deep. This zone was interpreted as a sheared and regionally metamorphosed hydrothermal system (Assessment Report 09783).

In 1983, Goldbrae Developments Ltd. conducted airborne magnetometer and very low-frequency electromagnetic surveys on the Fire (Hades and Brimstone) claims. This work identified two magnetic-high features, at least one of which is associated with pyrite and gold mineralization (Assessment Report 11952).

In 1984, the property was optioned to Tenquille Resources Ltd. Airborne, who completed very low-frequency electromagnetic and magnetometer surveys, as well as an air-photo tectonic survey. Further mapping and sampling continued through 1986 and a strong gold anomaly measuring 1000 by 100 metres was outlined, with a strike trending northwest by southeast.

In 1987, Englefield Resources Ltd. carried out 850 metres of diamond drilling in nine holes on the north side of Fire Creek. The best drillcore sample assays include 5.93 grams per tonne gold and 9.4 grams per tonne silver over 1.5-metre core lengths (Assessment Report 17508, page 18).

In 2004, Platinate Minerals and Industries Ltd. collected three rock samples from access roads in the Fire 1 and 2 claims as part of a placer exploration program, the best of which returned 0.01 gram per tonne gold and 1991 parts per million copper (Assessment Report 27667).

In 2005, Cumberland Resources Ltd. acquired claims covering the Fire Creek prospect and completed a program of mapping and geochemical sampling. Base and precious metal anomalies were variably distributed across the property (Assessment Report 28141).

In 2007, Agnico-Eagle Mines Limited acquired Cumberland Resources Limited and the Fire Creek prospect.

In 2011, Jose Barquet collected 11 rock samples for Agnico-Eagle along access roads (Assessment Report 32266).

In 2012, Agnico-Eagle collected 53 rock samples. Franklin Geoscience Limited statistically analyzed and interpreted the results of this and past work on the property. Franklin Geoscience interpreted the property as a vigorous shallow-water volcanogenic massive sulphide system, with the greatest apparent potential for mineralization southwest of the sampled area. This zone has the highest coincidental gold and base metal values, as well as sodium depletion and manganese enrichment (Assessment Report 33324).
