Resource Expansion

Vancouver – September 24, 2026 -- OceanaGold Corporation (TSX: OGC) (NYSE: OGC) reported new drill results from its Wharekirauponga project in New Zealand, including an intercept of 6.3 metres grading 97.2 g/t gold, among the highest-grade results returned to date at the deposit.

Sixteen new holes confirm high-grade continuity at Wharekirauponga's East Graben Vein

The 16 holes, completed since an April 1, 2026 update, targeted the East Graben (EG) Vein and adjacent Hanging Wall (HW) structures. Results included 8.5 m at 41.5 g/t gold from 399.0 metres depth, 9.6 m at 18.5 g/t gold from 401.0 metres, and 6.6 m at 24.0 g/t gold including a 1.2 m section at 107.7 g/t gold. The company said the intercepts extend the southern high-grade zone up-dip and along strike, an area currently outside reported reserves.

Nevada – September 21, 2026 -- i-80 Gold Corp. has completed a feasibility study for its Granite Creek Underground project outlining initial proven and probable mineral reserves of 556,500 ounces of gold at 7.87 grams per tonne across 2.20 million tonnes.

Measured and indicated resources jump 229% versus March 2025 preliminary assessment

The updated mineral resource estimate shows measured and indicated resources rising to 3.73 million tonnes grading 7.17 g/t gold, containing 859,500 ounces, a 229% increase from the PEA published in March 2025. Inferred resources fell 38% to 0.89 million tonnes at 7.06 g/t gold (202,800 ounces) as infill drilling converted material into higher-confidence categories. The estimate incorporates roughly 36,470 meters of drilling from 164 core holes completed between 2023 and the end of 2025.

Tonopah, Nevada – September 21, 2026 -- A2Gold Corp. (TSXV: AUAU) (OTCQX: AUXXF) (FRA: RR7) reported the highest-grade gold assay to date at its Eastside Gold-Silver Project, with drill hole CAC-007 returning 141.10 g/t gold over 0.9 metres roughly 53 metres below surface.

Drill hole CAC-007 delivers 141.10 g/t gold, the strongest result yet at Eastside

The intercept, recorded at 75.9 metres downhole within the existing Castle mineral resource, is tied to an interpreted northeast-striking structural zone where Tertiary volcanic rocks meet Paleozoic sedimentary basement. The result sits along the same structural trend as previously reported high-grade surface samples at Black Rock, which returned 10.50 g/t Au over 0.26 metres and 5.63 g/t Au over 0.28 metres. A2Gold flagged the roughly 400-metre corridor between Black Rock and CAC-007 as incompletely tested and a priority for follow-up drilling.

London – September 19, 2026 -- ACG Metals Limited (LSE: ACG) has more than quadrupled the post-tax net present value of its Gediktepe mine to approximately $1.2 billion, up from $265 million in 2024, following an updated Competent Person's Report prepared by SRK Consulting.

Ore Reserves jump 43% as copper content rises 34%

Total Ore Reserves increased to 26.5 million tonnes from 18.5 million tonnes in the 2024 CPR. In-situ reserves now contain 176kt of copper, 381kt of zinc, 535koz of gold and 20moz of silver, representing gains of 34%, 1%, 19% and 16% respectively versus the prior estimate.

Average annual output set to climb 60% to 36kt copper equivalent

Between 2027 and 2031, Gediktepe's average annual production is projected to reach approximately 36 kt CuEq, up from an original 20-25 kt target. Over an initial 11-year mine life, the operation is expected to produce a total of 352kt CuEq.
