Fyfe Lake Property
Fyfe Lake is a brand new discovery in south-central Yukon. The main target is a >9-km long package of steam-heated, oxidized, brecciated volcanics faulted against Triassic augite-phyric basalt, indicative of a fully preserved epithermal system. The property has strong potential to host porphyry mineralization like the adjacent Catch Property, where diamond drilling intersected 116.60 m of 0.31% Cu & 0.30 g/t Au by option partners Cascadia Minerals Ltd, and where new outcropping 1,065 g/t gold mineralization will be drill-tested in Q2 2025 at the Amp Zone.

-
Strongest geochem associated with a Triassic-Jurassic unconformity similar to the fertile "Red Line" Stuhini-Hazelton contact in BC
-
Boiling textures (quartz after calcite) near mapped structural intersections indicative of feeder system at depth.
-
Excellent geology broadly similar to British Columbia's Toodoggone District & Golden Triangle
Project Summary
-
The 50 sq. km, 100%-owned Fyfe Lake property is located 120 km north of the capital city of Whitehorse & 25 km from highway and grid power in south-central Yukon.
-
The project is accessible via floatplane or helicopter and lies within the Traditional Territory of the Little Salmon Carmacks First Nation.
-
The claims were staked in 2022 based on extensive research and a similar geologic environment to the adjacent Catch property, discovered by Burke in 2020.
Regional Geology
The Property lies within the Stikine Terrane, adjacent to a large flexure along the 1,000+ km long Teslin-Thibert fault. The Teslin-Thibert’s southern extension terminates near the Kemess-Toodoggone porphyry-epithermal district. The Stikine is characterized by Late Triassic to early Jurassic volcanic-plutonic arc complexes host to porphyry-epithermal systems including the Red Chris, Schaft Creek, Kemess-Toodoggone, KSM and Galore Creek deposits and mines.
Property Geology
-
The Fyfe Lake Project contains a central zone, currently 3 km long, consisting of steam-heated, altered and locally brecciated felsic tuffs and mudstones with localized fuchsite alteration. These rocks unconformably overlie pervasively altered Triassic basalts along faulted strands and splays of the Teslin-Thibert fault.
-
Structural intersections on the property represent escape conduits of deep-seated faults in the area.
-
The faulted unconformity between the volcanic tuffs and intrusive basalts is a compelling untested epithermal exploration target that is very similar geologically to the recent AuRORA discovery by Amarc Resources Ltd. in the Toodoggone district of British Columbia.
Historical Exploration
No previous work has ever been conducted on the property. Fyfe Lake represents a brand-new grassroots discovery in an underexplored prospective northern extension of the Stikine Terrane. Burke first began prospecting near the shores of Claire Lake in 2020, discovered abundant copper-gold mineralization, staked the Catch Property and performed additional exploration for the next two seasons. The Catch Property is now under option to Cascadia Minerals Ltd. and is being explored for copper gold porphyry and high grade epithermal mineralization. The Fyfe Lake property lies 8-km east of the Catch Property and was staked in 2022 using the same methodology that resulted in the discovery of Catch, and has again resulted in a grassroots discovery, speaking to the mineral potential of the area.
Modern Exploration
Several extensive exploration programs have been conducted yearly on the Fyfe Lake Property including claim staking, geochemical surveys, and geological mapping, resulting in:
-
Discovery of a high-level epithermal system and potential for a nearby associated copper-gold-molybdenum porphyry system
-
Discovery and expansion of the central steam heated lithocap with localized structurally controlled zones of fuchsite alteration in volcanics and feldspar porphyry.
-
Delineating the prospective unconformable contact via geological mapping for over 3 km in length, which remains open
-
Outlining a prominent geochemical anomaly within the lithocap and definition of structural intersections and boiling textures, suggestive of a fully preserved system at depth
Mineralized Zones
-
The Fyfe Lake Project currently contains a 3-km central zone of coherent arsenic, antimony, mercury, thallium and selenium geochemistry with localized gold, and secondary molybdenum copper geochemical anomalies.
-
Strongly brecciated, altered and vuggy silicification of felsic volcanics and mudstone is found throughout the entirety of the lithocap, with localized zones of bladed quartz indicating boiling of hydrothermal fluids.
-
Hyperspectral analysis indicates pervasive kaolinite alteration with localized zones of dickite and sericite alteration, suggesting hotter upwelling zones within. Two 98th percentile gold-in-silt anomalies are present in the creek immediately downslope of this area, suggesting gold potential of the lithocap at depth.
Future Work
Future work recommendations in the central portion of the property include a drone magnetic survey, geological mapping, and induced polarization surveys. Results of this work would lead to diamond drilling of the most compelling targets on the property.
Additional exploration on the western and eastern portions of the property to identify any potential associated porphyry mineralization is also recommended.
