DPM Metals Inc. (TSX: DPM, ASX: DPM) has announced expanded delineation drilling results at its Brevene Porphyry South gold-copper discovery in Bulgaria, delivering multiple high-grade intercepts including 716.60 metres grading 3.30 g/t gold equivalent from 1,357 metres downhole. The results confirm the porphyry system extends northward onto the adjacent Chelopech mine concession, meaningfully enlarging the project's development footprint. With a potassic alteration envelope exceeding 500 metres by 500 metres and more than 1,000 metres in vertical extent, investors may be watching this discovery closely as a potential Tier One growth asset.

Key Points

  • DPM Metals Inc. (TSX: DPM, ASX: DPM) released delineation drilling results for its Brevene Porphyry South discovery in Bulgaria
  • Drillhole EX_BRES_555_02A returned 716.60 metres grading 3.30 g/t AuEq, including 138.60 metres at 5.71 g/t AuEq from 1,935 metres downhole
  • Approximately 15,000 additional metres of drilling planned through year-end 2026; permitting activities advancing to convert the Brevene exploration licence to a mining concession
  • Investors may watch for further drill results from holes currently in progress and regulatory milestones under Bulgaria's permitting framework

Expanded Drilling Confirms Scale and Grade at Brevene Porphyry South

The latest results build on previously reported intercepts, with drillhole EX_BRESPO_03 now extending to 1,054 metres grading 2.49 g/t AuEq — comprising 1.20 g/t Au, 1.20% Cu, and 43.46 g/t Mo — from 1,172 metres downhole, including 465 metres grading 3.02 g/t AuEq. Multiple holes remain in progress, with EX_BRESPO_05 already returning 328 metres at 3.28 g/t AuEq and advancing through visible mineralisation. Both EX_BRES_555_02A and EX_BRESPO_03 were stopped due to technical limitations and terminated in mineralisation, meaning the system remains open at depth, according to the release.

System Extends onto Chelopech Mine Concession, Opening New Delineation Front

Drillhole EX_BRESPO_06 confirmed the porphyry system extends northward onto the Chelopech mine concession, returning 540 metres grading 1.31 g/t AuEq from 1,143 metres downhole. The disclosure states mineralisation remains open to the north, south, west, and at depth. With up to eight drill rigs dedicated to Brevene Porphyry South and approximately 15,000 additional metres planned through year-end 2026, the company is shifting drilling operations to the Chelopech concession as the Brevene exploration licence period concludes at the end of September 2026.

Preliminary Metallurgical Testwork Supports Conventional Flotation Processing

Testing at SLR Consulting's laboratory in the United Kingdom indicates Brevene Porphyry South mineralisation is amenable to conventional rougher-cleaner flotation. Open-cycle cleaner tests produced copper-gold concentrates grading between 10% and 25% copper and approximately 12 g/t to 20 g/t gold. The release states deleterious elements such as arsenic appear at trace levels and are not currently expected to reach penalty thresholds. Future testwork will evaluate the potential to produce a separate molybdenum concentrate, given the encouraging molybdenum response from composite sample MET_BSP26_03.

Permitting Progress Alongside Two-Decades of Local Operating Experience

The company submitted its final geology report — including a technical and economic assessment — to Bulgaria's Ministry of Energy in late August 2026, with regulatory review ongoing. Key milestones include recognition of a commercial discovery, submission of a mining concession application, and satisfaction of environmental requirements. The release notes DPM has more than two decades of operating experience in the Chelopech district, which the company states substantially de-risks future development and positions Brevene Porphyry South as a Tier One growth opportunity.
