Cascadia Continues to Demonstrate Expansion Potential at the Carmacks Copper-Gold Project, intersecting 42.88 m of 1.19% Copper with 0.34 g/t Gold
Drilling and Project Highlights
- Drilling at the Carmacks Deposit continues to demonstrate sulphide resource expansion potential, strong grade continuity and the predictable nature of mineralization;
-
Seven of the eight remaining holes intersected sulphide mineralization,
including broad intercepts such as 87.44 m of 0.63% copper with 0.15 g/t gold, 2.7 g/t silver, and 248 ppm molybdenum (0.88% CuEq) in hole CD-25-040 (Figure 3);
-
Multiple holes returned high-grade cores of over 1% copper, including 42.88 m of 1.19% copper with 0.34 g/t gold in CD-25-037, 21.27 m of 1.25% copper with 0.28 g/t gold in CD-25-040, and 25.20 m of 1.36% copper with 0.25 g/t gold in CD-25-035 (Figures 3-5);
- Planning is underway for a 15,000 m drill program in 2026 that will continue resource expansion at the Carmacks Deposit and evaluate adjacent targets including Zone 14, where drilling in 2007 returned 16.37 m of 1.04% copper in WC-140, and the
Gap Zone , where drilling in 2024 returned 29.75 m of 0.50% copper in CRM24-027 (Figure 1); - Regional exploration will test additional targets throughout the 177 km2 property, including Zone A, 11 km north of the Carmacks Deposit, where drilling in 1980 returned 22.86 m of 2.27% copper with 2.20 g/t gold in 80-18 (Figure 6); and,
- All significant intercepts returned grades above the cut off grade for the 2023 Preliminary Economic Assessment, highlighting the potential to increase tonnage of the deposit.
"These excellent results reinforce our confidence in the scale and growth potential of the Carmacks Deposit. With mineralization remaining open in multiple directions across all zones, we see a clear path to materially expanding the resource base at the

Carmacks Drilling Summary
Eleven holes totalling 3,847.95 m were completed at the Carmacks Deposit in fall 2025. All holes targeted expansion of sulphide resources through step-outs or by testing significant gaps in drilling within the sulphide block model. Mineralization was encountered in ten of the eleven holes. Results from holes CD-25-030, 031 and 033 in Zone 147 were previously reported (see news release dated

The Carmacks Deposit is located in the northern part of the Stikine Terrane, which extends into
The deposit comprises a series of 5-100 m wide 'rafts' of variably migmatized xenolithic meta-sedimentary and meta-volcanic rocks hosted within the coarse crystalline granitoids of the Granitoid Mountain Batholith suite. The 'rafts' generally trend NNW-SSE over 3 km of strike length and form three distinct zones of mineralization. Sulphide mineralization is confined to the metamorphic 'rafts' and is found as chalcopyrite-bornite foliation parallel stringers as well as net-textured clots, interpreted as evidence for later sulphide melts. The contacts with the intrusive phases of the granite mountain batholiths are sharp and unaltered. The Carmacks property geology and deposit model are thought to be similar to the nearby Minto Deposit, with past work suggesting that the system is the result of an alkalic porphyry deposit that was metamorphosed up to the point of partial melting at depths of up to 25km, followed by rapid uplift to near surface.
The deposit is in an area of central
With the success of the 2025 drilling, planning is underway for a significantly expanded 2026 exploration program, targeting a minimum of 15,000 m of diamond drilling. Continued drilling at the Carmacks Deposit will test further expansion of the three current zones. Drilling in 2026 will also advance multiple near-deposit targets that lie outside the current resource, including Zone 14, where drilling in 2007 returned 16.37 m of 1.04% copper in WC-140, and the
A broader regional program is planned to evaluate numerous historical targets across the 177 km2 Carmacks property, which covers a significant portion of the Minto Copper Belt (Figure 5). A key priority will be follow-up work at Zone A, where drilling in 1980 encountered high-grade copper and gold over a 350 m strike length, including 13.72 m of 3.18% copper with 2.01 g/t gold (80-09) and 22.86 m of 2.27% copper with 2.20 g/t gold (80-18).
Zone 147 Drilling
Holes CD-25-030, 031, 033, and 037 were drilled at the Zone 147, testing sulphide mineralization at depth in the northern part of the Carmacks Deposit. Holes CD-25-030, 031, and 033 were previously reported.
Hole CD-25-037 targeted a gap in drilling between holes CD-25-030 and CD-25-033. It returned 42.88 m of 1.19% copper with 0.34 g/t gold, 3.9 g/t silver, and 88 ppm molybdenum (1.52% CuEq), including 23.10 metres of 1.61% copper with 0.44 g/t gold, 5.1 g/t silver, and 117 ppm molybdenum (2.05% CuEq). This hole demonstrates the continuity of sulphide mineralization at depth and indicate that mineralization remains open further down dip. This drilling also confirms consistently elevated gold grades are present at Zone 147 compared to other areas of the deposit.
Zone 2000S Drilling
Holes CD-25-039 and 040 were drilled at Zone 2000S to step out on previous drilling and test different drill orientations at depth. Both holes intercepted long intervals of mineralization in a series of subvertical zones hosted in metamorphosed mafic volcanic rocks, with higher grade cores returning 17.37 m of 1.09% copper with 0.31 g/t gold, 3.6 g/t silver, and 227 ppm molybdenum (1.46% CuEq), and 21.27 m of 1.25% copper with 0.28 g/t gold, 5.8 g/t silver, and 171 ppm molybdenum (1.60% CuEq), respectively. Mineralization in the 2000S Zone is characterized by a near vertical zone and is more enriched in molybdenite compared to Zone 147.
Zone 1213 Drilling
Holes CD-25-032, 034, 035, 036, and 038 were drilled at Zone 1213 to test for extensions of sulphide mineralization at depth and within large gaps in historical drilling. Sulphide mineralization in this zone is more shallowly dipping and closer to surface compared with the two zones to the north. Mineralization at this zone also exhibits a comparably higher amount of hypogene bornite in addition to chalcopyrite.
CD-25-032 was drilled in the southern part of Zone 1213 to test the down dip extent of known mineralization in an area with very limited shallow previous drilling. This hole was drilled beneath metamorphosed volcanic rocks and did not intercept mineralization.
CD-25-034 was drilled to test the down dip extent of mineralization in the middle of Zone 1213 where only shallow drilling has been previously completed. This hole returned 15.11 m of 0.40% copper with 0.10 g/t gold, 1.6 g/t silver, and 30 ppm molybdenum (0.51% CuEq), extending mineralization 50 m beyond previous drilling.
CD-25-035 tested a significant step out at depth in the core of the zone. This hole intercepted a high-grade core returning 25.20 m of 1.36% copper with 0.25 g/t gold, 4.8 g/t silver, and 169 ppm molybdenum (1.67% CuEq) within a significant broader zone of 60.12 m of 0.84% copper with 0.16 g/t gold, 3.0 g/t silver, and 98 ppm molybdenum (1.03% CuEq).
CD-25-036 was drilled to test a gap in historical drilling in the core of Zone 1213. This hole intercepted a shallow, broad zone of sulphide mineralization returning 95.10 m of 0.63% copper with 0.14 g/t gold, 1.9 g/t silver, and 114 ppm molybdenum (0.80% CuEq), consistent with historical drilling. Mineralization remains open at depth in this area.
CD-25-038 was drilled to test the down dip extent of mineralization along the northern part of the 1213 Zone in an area of relatively sparse historical drilling. This hole intercepted a high-grade core returning 12.79 m of 1.48% copper with 0.24 g/t gold, 6.4 g/t silver, and 520 ppm molybdenum (1.95% CuEq) within a shallow, broad zone of sulphide mineralization returning 95.94 m of 0.53% copper with 0.12 g/t gold, 2.0 g/t silver, and 272 ppm molybdenum (0.76% CuEq). Mineralization remains open at depth in this area.
Carmacks Project Overview
Cascadia's 177 km2
The Carmacks Main Deposit has a Measured and Indicated Resource containing 651 Mlbs of copper and 302 koz of gold (36.3 million tonnes grading 0.81% copper, 0.26 g/t gold, 3.23 g/t silver and 0.01% molybdenum) or 1.07% copper equivalent, and an Inferred Resource containing 38 Mlbs of copper and 13 koz of gold (2.9 Mt grading 0.60% copper, 0.16 g/t gold, 2.34 g/t silver and 0.02% molybdenum). A 2023 preliminary economic assessment demonstrated positive economic potential, with a
The Carmacks Main Deposit is comprised of three zones, 147, 2000S and 1213, all of which remain open to expansion in multiple directions. Historical drilling at the deposit focused primarily on oxide copper mineralization, and numerous holes were ended when sulphide mineralization was encountered. Zone 1213 in particular hosts very shallow sulphide mineralization that has seen limited drilling.
