Work History

P.F. Guder the Revenue Copper in 1950, re-staked it as Revenue Copper cl 1-8 (67180) in September 1953 and tied on Addition cl 1-2 (68060) to the south in January 1954. Between September 1967 and March 1968, 25 Inca, Revenue, Rev and Add claims were added to the fringes of the property. A new company, Yukon Revenue Mines Ltd, was formed in 1968 to develop the property. Yukon Revenue changed its name to YKR International Resources Ltd in 1996.

In 1999, ATAC Resources Ltd optioned the Revenue claims from YKR and tied on Nuc cl 1-7 (YC09279) to the north in February 1999. At the same time, ATAC purchased the adjoining Nucleus claims (MINFILE occurrence 115I 107) from the W4 Joint Venture consolidating a total of 151 claims in the area to form a single contiguous claim group, which they named the Golden Revenue property.  

The Golden Revenue property was further consolidated in 2006 by Northern Freegold Resources. Northern Freegold Resources performed a property wide VTEM and magnetic airborne survey in 2006. In 2011, Northern Freegold drilled 7 diamond drill holes at WAu Bx.

Triumph Gold acquired Northern Freegold Resources in 2015 and the property is now termed the Freegold Mountain Project. Triumph carried out diamond drilling at WAu Bx between 2017 and 2020, as well as a ground magnetic survey, ground IP survey and soil sampling in 2018.

Regional & Property Geology

The occurrence is partly underlain by Yukon-Tanana Terrane (YTT). The rocks of the YTT in this region consist of Early Mississippian metamorphic rocks separated into meta-sedimentary and meta-igneous suites. The meta-sedimentary suite consists of micaceous quartz-feldspar gneiss, schist and quartzite. The meta-igneous package is comprised of biotite-hornblende feldspar gneiss and coarse-grained granodiorite orthogneiss with lesser amphibolite.

The YTT basement rocks are cut by numerous plutonic and volcanic events from the Mesozoic (Murray & Friend, 2018), including:
1. Early Jurassic Long Lake monzonite to syenite plutonic suites;
2. Mid-Cretaceous Mount Nansen Suite andesite to diorite;
3. Mid-Cretaceous Whitehorse granodiorite, quartz monzonite and granite;
4. Late Cretaceous Casino quartz monzonite;
5. Late Cretaceous Prospector Mountain syenite; and,
6. Quartz feldspar and feldspar hornblende porphyry dykes and plugs.

The major structural feature in the area is the Big Creek Fault with steeply-dipping, northwest-trending dextral faults parallel to the more regional Tintina and Denali faults (AR 097175).

Mineralization & Results

The WAu Bx prospect was first identified in 2017 and is a steeply plunging hydrothermal breccia hosted in granodiorite to the immediate east of the Revenue tuff breccia (MINFILE occurrence 115I 042). It predates the emplacement of the Revenue breccia and postdates earlier porphyry-style mineralization. The WAu breccia is associated with elevated tungsten, lead, and zinc that give an epithermal signature to the breccia. Mineralization consists of variable amounts of chalcopyrite, molybdenite, galena, sphalerite, bismuthinite, and visible gold in a set of late quartz-carbonate veins (Triumph Gold Corp., Technical Report, 2020).

Drilling in 2017 by Triumph Gold intersected 0.971 g/t Au, 7.38 g/t Ag, 0.218% Cu and 0.014% Mo over 58.65 m in RVD17-12 at WAu Bx. In 2018, drilling intersected 0.64 g/t Au, 2.1 g/t Ag, 0.17% Cu and 0.037% Mo over 128 m in RVD18-08. In 2019, drilling intersected 0.73 g/t Au, 6.9 g/t Ag, 0.23% Cu, and 0.025% Mo over 400.5m, not including the deep potassic zone, in RVD19-02 (Triumph Gold, News Releases, 19 Oct/2017; 31 Jul/2018; 12 Sep/2019).

The WAu drilling results have been incorporated into the Revenue deposit (MINFILE occurrence 115I 042) NI 43-101 compliant resource/reserve estimate published in 2020.
