ORETERRA METALS (TSXV: OTMC)

Oreterra Metals Corp. (CSE: OTMC) is a British Columbia focused copper gold exploration company advancing the Trek South porphyry copper gold target in BC’s Golden Triangle, immediately adjacent to Teck and Newmont’s Galore Creek district infrastructure. The company’s strategy centers on drilling a large, newly exposed, never drilled porphyry system that management believes has the scale and geological signature to support a major discovery. Trek South is defined by a roughly 1.6 kilometer by 1 kilometer target area with extensive bare bedrock exposure, strong porphyry style alteration, abundant visible copper minerals, and widespread copper, gold, silver, tungsten, molybdenum and tellurium values at surface and in nearby mineralized boulders. The core investment thesis is built around the coincidence of multiple large scale exploration vectors, including an at least 850 meter long by 500 meter wide IP chargeability anomaly extending to more than 650 meters depth, a coincident resistivity low, an approximately 850 meter by 850 meter magnetic high, and a deep running magnetotelluric anomaly interpreted to extend to at least 2 kilometers depth. These features sit below exposed alteration and mineralization, suggesting potential for a deeper potassic core that could host higher grade copper gold mineralization, similar in concept to other alkalic porphyry systems in the region. The project also benefits from strategic location, with Trek South situated only a few kilometers from Galore Creek access infrastructure, including partially completed road, bridges, camp and heavy equipment areas, and approximately 12 kilometers from the proposed Galore Creek mill site. Management has direct relevant experience in the region, including CEO Kevin Keough’s prior involvement with GT Gold, whose Saddle North copper gold porphyry discovery in the Golden Triangle was ultimately sold to Newmont for C$456 million. Near term catalysts center on Oreterra’s 2026 Phase 1 drill program, which contemplates 4,650 meters in eight widely spaced angled core holes targeting the prominent magnetic high and coincident IP chargeability anomaly beneath intense porphyry style alteration and copper, gold and silver values in bedrock, with a Phase 2 program of 4,600 additional meters contingent on Phase 1 success. With approximately C$8.3 million in cash, no debt, a recently completed financing, a tight capital structure, 100 percent ownership of Trek South subject to a 2 percent NSR, and a drill ready target in one of Canada’s most prolific mineral belts, Oreterra offers investors leveraged exposure to a potential new copper gold porphyry discovery in the Golden Triangle.

Oreterra Metals Corp. (CSE: OTMC)

A British Columbia focused copper gold exploration company advancing the Trek South porphyry copper gold target within BC’s Golden Triangle. The company’s strategy is centered on testing a large, drill ready, never drilled porphyry target that management believes has the geological, geochemical and geophysical signatures of a potentially major copper gold discovery. Oreterra is positioning Trek South as a high impact discovery story with district scale upside, strong infrastructure proximity and a management team with prior Golden Triangle porphyry success.

Market Focus

Oreterra operates within the Canadian copper gold exploration market, with a focus on large scale porphyry systems in BC’s Golden Triangle. The company is positioned in one of Canada’s most important mineral belts, adjacent to the Teck and Newmont Galore Creek joint venture, a major copper gold district currently advancing through development studies. Oreterra’s market exposure is driven by copper, gold and silver demand, exploration success, and investor appetite for major discovery potential in tier one jurisdictions.

Platform and Strategy

Oreterra’s operating model is built on three core pillars.

• Drill test Trek South as a large scale copper gold porphyry discovery target with coincident surface mineralization, alteration and geophysical anomalies.

• Leverage the strategic location beside Galore Creek infrastructure, including partially completed roads, bridges, camp facilities and proposed development corridors.

• Use experienced technical leadership, historical district knowledge and modern geophysical interpretation to identify the deeper potassic core of the system where higher grade porphyry mineralization may be concentrated.

Asset Base and Development

• Trek South copper gold porphyry target located in BC’s Golden Triangle.

• Target scale of approximately 1.6 kilometers by 1 kilometer.

• Oreterra owns 100 percent of Trek South, subject to a 2 percent NSR.

• Project located adjacent to the Teck and Newmont Galore Creek joint venture.

• Trek South is approximately 2 to 3 kilometers from Galore Creek infrastructure, including partially completed road, bridges, camp and heavy equipment areas.

• Project is approximately 12 kilometers from the proposed Galore Creek mill site along the same access route.

• The target is positioned outboard to the Trek Fault, a structural setting also associated with known porphyry style mineralization at Trek North.

• Trek North, located about 3 kilometers north of Trek South, previously returned strong copper gold silver porphyry style drill results, including 46.6 meters grading 1.49 percent copper, 0.77 grams per tonne gold and 17 grams per tonne silver.

Operational Advancement

• Oreterra completed a NI 43 101 technical report on the Trek property dated January 20, 2026.

• Trek South has advanced from early mapping and sampling to a drill ready target.

• Field work has identified extensive bare bedrock exposure, allowing direct visual confirmation of alteration and mineralization across a large target area.

• Surface work has outlined intense epidote alteration, red garnet epidote skarn veins and bands, a more than 1,000 meter wide quartz pyrite stockwork and locally mineralized biotite porphyry dykes.

• Visible copper minerals have been identified across the exposed bedrock and in up ice boulders, including chalcopyrite, chalcocite, bornite, malachite and azurite.

• Stockwork sampling returned widespread copper, gold and silver enrichment, with approximately half of samples assaying 0.2 to 1.7 grams per tonne gold, 0.1 to 1.83 percent copper and 2.3 to 257 grams per tonne silver.

• Skarn sampling also returned copper tungsten values, including chip sampling of 4.61 meters grading 0.37 percent WO3 and 0.24 percent copper.

• Mineralized boulders have assayed up to 8.8 grams per tonne gold, 46 grams per tonne silver and 2.8 percent copper.

Exploration and Growth Pipeline

• Trek South has never been drilled.

• The main target is defined by a large, strong IP chargeability anomaly measuring at least 850 meters long by 500 meters wide and extending to more than 650 meters depth.

• The IP anomaly is coincident with a resistivity low, suggesting a large volume of sulphides below the surface alteration.

• A strong magnetic anomaly measuring approximately 850 meters by 850 meters underlies the alteration and surface metal values.

• A deep running magnetotelluric anomaly is interpreted to extend to at least 2 kilometers depth.

• The company believes the magnetic and geophysical signature may indicate a deeper potassic core, which in alkalic porphyry systems is commonly associated with higher grade copper gold mineralization.

• Phase 1 drilling is planned to include 4,650 meters in eight widely spaced angled core holes.

• Phase 1 will target the magnetic high and coincident IP chargeability anomaly beneath intense porphyry style alteration and copper gold silver values in bedrock.

• Phase 2, contingent on Phase 1 success, would include an additional 4,600 meters of drilling in eight widely spaced angled core holes.

• The combined Phase 1 and Phase 2 drill plan totals approximately 9,250 meters with an estimated combined budget of about C$6.8 million.

Partnerships and Strategic Positioning

Oreterra is strategically positioned beside one of the most important copper gold districts in the Golden Triangle. Trek South’s proximity to the Galore Creek joint venture gives it unusual infrastructure relevance for an early stage discovery target. A discovery at Trek South could potentially benefit from nearby access routes, proposed development infrastructure and district level attention from major mining companies already active in the area. The company also highlights that Trek South is located in terrain with limited vegetation, broad exposed bedrock and moderate drilling topography, which may reduce early exploration complexity relative to many BC mountain projects.
