Trifecta Gold Announces ZTEM and Magnetic Results from Mt. Hinton Project, Yukon and
Describes Ongoing Research Studies
October 1, 2024
• New exploration results provide strong evidence that mineralization at Mt Hinton is related
to a previously unidentified, Reduced Intrusion Related Gold System (“RIRGS”).
• Geophysical surveys delineated a 2,000 x 500 metre magnetic low that coincides with an area
of high resistivity in an overburden covered area that has seen no trenching or drilling.
• Prospecting discovered granitic rocks near the geophysical anomalies, further validating the
RIRGS model.
• Mineralogical studies are underway at Simon Fraser University to better characterize the
known vein system and determine its relationship to other mineralization in the Tombstone
Gold Belt.
October 1, 2024 - Trifecta Gold Ltd. (TSX-V: TG) (OTCQB: TRRFF) (“Trifecta” or the “Company”)
announces results from its multifaceted 2024 exploration campaign at Mt. Hinton . The Mount Hinton
Project (the “Project”) is ideally located less than 4 km from Hecla Mining Company’s Keno Hill mine and
mill complex, within a belt of Reduced Intrusion Related Gold Systems (“RIRGS”) that includes current
and former producers and major new discoveries such as Banyan Gold’s AurMac deposit, 20 km to the
west, Sitka Gold’s RC deposit, 80 km to the west, and Snowline Gold’s Valley deposit, 180 km to the east
(Figure 1).

Geophysical target delineated
A 440-line kilometre, ZTEM (“Z-Axis Tipper Electromagnetic”) and magnetic survey s, flown over the
southeastern portion of the Project, have delineated a 1.9 by 1.2 km magnetic high and flanking 2.0 by 0.5
km magnetic low that corresponds with an outstanding, strong resistivity anomaly (the “GC target”) (figures
2 and 4). These features are commonly associated with the RIRGS model, which typically exhibits a
magnetic low directly over a reduced intrusion, flanked by magnetic highs within a surrounding hornfelsed
aureole. High resistivity readings are often observed over the hornfelsed rocks but can also be found over
strongly silicified zones within the intrusion. The geophysical features at the GC Target are indicative of a
hornfelsed aureole overlying a buried intrusion, which may come to surface in the valley floor, within the
central magnetic low.
The target is located on a glacial till and talus covered valley floor, directly east of the mouth of the Granite
Creek Basin (Figure 3). Placer miners operating at the mouth of the Granite Creek Basin often encounter
upwards of 10 m of glacial till above productive placer channels, precluding the use of soil geochemistry
to evaluate the target. First-pass prospecting in 2024, within the GC target, successfully identified abundant
coarse-grained granitic rocks in float (Figures 5 and 6) , providing direct evidence that an intrusive body
located on the southeastern portion of the Project could be the driver to mineralization found elsewhere on
the Project.

Prospecting
Prospecting within a previously identified soil anomaly to the southwest of the GC target returned 2.07 g/t
gold. The mineralization in this area is hosted in narrow veinlets cutting quartzites (Figure 7). This is the
first mineralization reported from that part of the Project.

quartzite, yielded 2.07 g/t gold.
Drilling
As announced September 5, 2024 , Trifecta ’s drill program was limited to one hole due to a series of
equipment issues. Hole MH-24-038 targeted the down dip projection of the 85 vein where prospecting had
discovered vein material grading 273 g/t gold with 284 g/t silver and 138.5 g/t gold with 57.5 g/t silver.
MH-24-038 encountered two unmapped faults and did not return any significant results for gold. Drill roads
and pads were constructed at the SW Zone and No. 5 Vein in order to facilitate future drilling of the western
extensions of these prominent structures. Highlights from previous drilling include:
• 6.44 g/t gold and 2.51 g/t silver over 12.14 m in hole MH-20-22 (SW Zone);
• 3.86 g/t gold and 182 g/t silver over 9.75 m in hole MH-20-18 (SW Zone);
• 128.91 g/t silver over 3.05 m in hole H-4, no assays for gold (No. 5 Vein); and,
• 78.88 g/t silver over 7.62 m in hole H-13, no assays for gold (No. 5 Vein).
Mapping
Geological mapping at Mt. Hinton was performed as part of a multi-year research program in the Keno Hill
District, undertaken by the Yukon Geological Survey (“YGS”), Simon Fraser University, the University of
Alberta and partner companies. This work is intended to better characterize the styles of mineralization at
Mt Hinton and other projects within the Keno Hill District and to determine its context within the broader
Tombstone Gold Belt. During a site visit relating to this program a rock specimen with blades of visible
gold was collected by Patrick Sack of the YGS from the Granite North Zone (Figure 8). Many high-grade
rock samples have been collected from the Granite North Zone with assays up to 2,340 g/t gold , while
drilling in 2020 returned several highlight intercepts:
• 6.74 g/t gold and 186 g/t silver over 7.25 m, including 1.77 m grading 22.7 g/t gold and 514 g/t
silver, in hole MH-20-019 (Granite North Zone);
• 17.00 g/t gold over 1.56 m, in hole MH-20-032 (Granite North Zone); and,
• 9.57 g/t gold over 1.47 m , including 0.52 m grading 25.8 g/t gold, in hole MH -20-023 (Granite
North Zone).
