The Fisher occurrence is located near the headwaters of Wrede Creek on a northeast-facing slope, approximately 9 kilometres north-northwest of Johanson Lake (Assessment Report 14630). The occurrence is similar to the Quyzvhx occurrence (094D 010), 2 kilometres to the southeast.
The Fisher area is underlain by Upper Triassic volcanic rocks of the Takla group, represented by felsic to intermediate volcanics and clastic sedimentary rocks. In order of abundance, the rock types are; andesitic tuffs, lapilli tuffs, agglomerates and flows (Assessment Report 14630). The sedimentary rocks are predominantly dark grey to black argillites intercalated within the volcanics. The general strike of the sedimentary rocks is east-west, dipping approximately 30 degrees to the north (Assessment Report 14630). These rocks are intruded by hornblende diorite and hornblende biotite diorite dykes and sills. The dikes and sills are 0.5 to 8 metres in thickness (Assessment Report 14630).
Shearing has developed near the contact of the sedimentary and volcanic rocks with the dykes and sills. Alteration haloes are relatively thin and typically extend 1 metre from the intrusive contacts (Assessment Report 14630). An alteration zonation is present; the rocks close to the intrusions are clay and silica altered and further from the intrusions, the rocks exhibit chlorite and epidote alteration (Assessment Report 14630). Alteration within the intrusion is primarily uralitization and chloritization of the mafic minerals, with lesser sericitic and epidote alteration.
The Fisher vein is a 5- to 10-centimetre-thick white quartz vein traceable for 35 metres. The vein strikes 160 degrees and dips 52 degrees to the southwest (Assessment Report 14630). The quartz vein is vuggy, fractured and cuts hornblende porphyritic flows and altered epidote and silica altered tuffs. Mineralization consists of chalcopyrite, galena, with minor malachite and azurite and associated pyrite. A grab sample from this vein assayed 1.371 grams per tonne gold (Assessment Report 14630).
Stratigraphically below the Fisher vein, some of the fragmental andesites are silicified and contain stringers of fine-grained chalcopyrite and pyrite. The unit is anomalous in gold, containing 0.36 gram per tonne gold locally (Assessment Report 14630). The volcanic rocks are intruded by a 1-meter-wide diorite dike which contains disseminated chalcopyrite and malachite, but is not anomalous in gold or silver.
WORK HISTORY
The historic Inge claims covered the QUYZVHX showing which was first staked in 1948 by A.B. Goodridge and O.C. Chayer and later acquired by Golden Rule Resources Ltd. in April of 1980.
Between 1980 and 1984, Golden Rule Resources Ltd. carried out VLF-EM and Magnetic geophysical surveys, geological mapping, prospecting and geochemical sampling activities. The Solomon gold-quartz vein was discovered in the fall of 1983 yielding up to 101.13 grams per tonne gold over one meter, and a grab sample reportedly returned 272.13 grams per tonne gold (Assessment Report 21358).
In 1985, the claims were optioned by Suncor Inc. who carried out geological mapping and prospecting over most of the property as well as detailed mapping and sampling in selected locations. This led to the discovery of the Fisher vein, a 5-10-centimetre-wide quartz-carbonate vein containing up to 0.67 gram per tonne gold within shear zones (Assessment Report 21358).
In 1986, Suncor’s option was passed on to Ritz Resources Ltd. who conducted grid VLF-EM and magnetic surveys, geological mapping, and further sampling of the QUYZVHX and Solomon veins. The Solomon vein assayed up to 97.57 grams per tonne gold and the QUYZVHX vein returned a maximum assay of 0.37 gram per tonne gold (Assessment Report 21358).
Ritz continued working the property until 1989 carrying out further geophysical surveys, including a DIGHEM airborne survey which identified a number of short electromagnetic conductors as well as a long magnetic anomaly underlying the central valley (Assessment Report 21358; Assessment Report 17409).
In 1990, Ritz Resources carried out a soil sampling program comprised of two lines, collecting 73 soil samples over the two aeromagnetic anomalies detected in 1988. Soil line 1 determined 5 samples (out of 36) to be weakly to moderately anomalous in gold, and soil line 2 determined 12 samples (out of 37) to be weakly to moderately anomalous in gold, with gold values ranging between 20 and 50 ppb (Assessment Report 20109). In the same year, Golden Rule Resources Ltd. carried out geological mapping over 25 hectares and excavated 8 trenches over 245 metres, targeting the Solomon Vein, QUYZVHX Vein, and the Sheba Vein. During this program 92 rock samples were collected, however, none carried economic grades of gold or silver.
In 2007, Serengeti Resources Ltd. carried out a geophysical survey over the Fleet claims which included: airborne EM, magnetic, and radiometric surveys over 434 km. The radiometric survey highlighted an area of high potassic/low thorium count in the extreme north of the claim block which could be indicative of potassic alteration. A number of magnetic highs were also outlined which are generally indicative of intrusive bodies. The survey covered the following MINFILE showings (Assessment Report 29768): Wrede Creek (094D 009), QUYZVHX (094D 010), Wrede Creek Chromite (094D 026), Red (094D 034), (NIK (094D 109), Shred (094D 111), Fox (094D 156), Hound (094D 157), Hat (094D 158), Midas (094D 159), Fisher (094D 160), Inge (094D 161), Redgold (094D 162), Grapes (094D 163), 04PSC-94 (094D 186). The magnetic survey showed a sharp linear gradient trending northwest through the southern-central portion of the survey block, indicative of a fault contact between intrusive rocks on the east and Takla volcaniclastics on the west. A linear northwesterly trending magnetic high is seen to the west of the northwesterly trending fault. The Shred, Hound, Fox, Wrede Creek and possibly Fisher showings appear to be related to it, at least spatially.
In 2008/2009, a limited induced polarization (IP) and magnetic survey was conducted on the Nik and the Fleet claims on behalf of Serengeti Resources Inc. Although the results on the Nik were complicated by the strike direction three zones of higher chargeability were observed generally trending northwesterly across the lines, while a wide zone trending in the same direction was detected on the Fleet (Airborne Magnetic Survey Maps (Fleet Project), Assessment Report 31136). The Midas occurrence and some of the headwaters of the creek were covered by the geophysics survey completed on the Fleet property.
In 2015, on behalf of D.L. Cooke, a survey of linear features mapped from satellite remote sensing data was completed (Assessment Report 35425). The purpose of the study was to identify geological structures which may be associated with gold and/or copper occurrences several of which occur in the area of interest: Wrede Creek (094D 009), Red (094D 034), Bird (094D 101), Shred (094D 111), Hat (094D 158).
In 2018 to 2019, Intact Gold Corp. held the Little Phoenix Property which covered the following mineral occurrences: Hound (094D 157), Fox (094D 156), Shred (094D 111), QUYZVHX (094D 010), Fisher (094D 160), and Inge (094D 161). Precision Geo Surveys Inc. completed a 349-kilometre magnetic airborne survey on behalf of Intact (Assessment Report 38448).
In 2021, Wedgemount Resources Corp. completed a program of geochemical (rock and soil) sampling and spectral analysis on the area surrounding area as the regionally extensive Cookie property.
