Work History
The Elephant cl 1-14 (YA86794) were staked in April 1985 by G. Lee and optioned to Noranda Exploration Company Ltd, which staked Elephant cl 15-20 (YA96415) and performed mapping, trenching and geochemical sampling in 1986 and 1987.
B. Harris staked the Rag 25-26 cl (YB46562) to the southwest in December 1993. In October 1993, the Elephant claims and Rag cl 25-26 were optioned to La Rock Mining Corp. In December 1996, La Rock filed for assessment credit on the Elephant claims for a soil survey carried out on the Glen claim located immediately to the north.
Northern Freegold Resources consolidated the claims in 2006 as part of their Golden Revenue property and performed a property wide VTEM and magnetic airborne survey, including the Elephant occurrence.
Triumph Gold acquired Northern Freegold Resources in 2015 and the property that includes the Elephant occurrence is now termed the Freegold Mountain Project.
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). The claims cover a pendant of Paleozoic hornblende-biotite-feldspar gneiss and schist within Jurassic monzonite directly to the north and Cretaceous Casino monzonite to the south (AR 092113).
Mineralization & Results
A number of gold-silver-arsenic soil geochemical anomalies range up to 2,200 ppb Au, 5.8 ppm Ag and 2,560 ppm As, but no mineralization has been found in situ.
Grouping regulations allowed La Rock to claim assessment credit for work performed on the Glen claims (MINFILE occurrence 115I 121).
