Dpm Metals Announces Discovery of High-Grade Gold-Copper Porphyry Mineralization At Brevene South Porphyry Target
DPM Metals Inc. announced a major new discovery of high-grade, gold-copper porphyry mineralization at the Brevene South Porphyry (BSP) target, located in the southeastern part of the Company’s Brevene exploration licence and contiguous with the Chelopech mine concession. Initial results from drilling program at BSP demonstrate potential for scale and continuity with broad, continuous intervals of high-grade gold-copper porphyry mineralization. Selected intercepts include: EX_BRESPO_03: 713 metres grading 2.52 g/t AuEq, comprising of 1.31 g/t Au and 1.16% Cu from 1,172 metres downhole, including 398 metres grading 3.00 g/t AuEq, comprising of 1.48 g/t Au and 1.45% Cu from 1,487 metres downhole (hole ongoing). EX_BRES_555_02: 95 metres grading 0.93 g/t AuEq, comprising of 0.43 g/t Au and 0.48% Cu from 1,250 metres downhole. EX_BRES_555_02A: 37 metres grading 1.19 g/t AuEq, comprising of 0.53 g/t Au and 0.63% Cu from 1,357 metres downhole (hole ongoing). The BSP is located approximately one kilometre from existing Mineral Reserves and contiguous to the Chelopech mine concession. A large phyllic alteration envelope exceeding 1,000 metres by 1,500 metres indicates a substantial hydrothermal system, with the BSP target remaining open for expansion. Drilling continues with the aim of expanding known mineralization, with five high-capacity drill rigs dedicated to the target and up to 15,000 metres planned through the end of 2026. As part of an intensive exploration program aimed at expanding the mineral resource inventory of the Chelopech mine, deep drilling commenced earlier this year in the southeastern part of the Brevene licence. The current drilling phase follows an internal target-generation initiative that re-evaluated existing data from previous exploration campaigns, including all deep exploration drillholes below and proximal to the existing orebodies. By integrating exploration geochemistry datasets, hyperspectral mineralogical data and geophysical models with geological observations, vectors toward a porphyry center were identified and the BSP target area was defined. Alteration data further outlined a large phyllic alteration envelope exceeding 1,500 metres by 1,000 metres, which has been traced from the southeastern part of the Chelopech mine concession into the southern part of the Brevene exploration licence. Drillhole EX_BRESPO_03 intersected high-grade gold-copper porphyry mineralization from 1,172 metres downhole depth, approximately 1,000 metres vertically below surface at an elevation of -380 metres, on the southeastern flank of the Chelopech mine. At the time of this news release, EX_BRESPO_03 has returned an interval of 713 metres at an average grade of 2.52 g/t AuEq (1.31 g/t Au and 1.16% Cu) from 1,172 to 1,885 metres downhole. The hole remains in progress and has now reached a depth of 2,031 metres downhole, continuing in strongly altered and intensely mineralized intrusive rock. The mineralization is hosted by a strongly altered porphyritic intrusion and is associated with a high density of quartz-dominated stockworks and sheeted veins, locally resulting in “brain rock”-style replacement textures. Early-stage potassic alteration and quartz veining are overprinted by a chlorite-mica-magnetite-quartz-anhydrite assemblage. Both stages host abundant chalcopyrite-pyrite mineralization, occurring in quartz-sulphide-magnetite veins and as disseminations in the groundmass. Drillhole EX_BRES_555_02 was designed to test the northern part of the target area from an underground location within the Chelopech mine. Below 1,100 metres, drilling intersected a transition from high-temperature advanced argillic alteration into a more phyllic-type assemblage marked by the presence of paragonitic muscovite. From approximately 1,250 metres depth, the interval becomes strongly silica-flooded, with trace potassic alteration and stockwork quartz-pyrite-chalcopyrite-bornite bearing veins. Assay results from this zone returned 95 metres of porphyry-style mineralization grading 0.93 g/t AuEq, comprising 0.43 g/t Au and 0.48% Cu. The hole was stopped before reaching its planned depth due to technical limitations related to drill rig capacity. EX_BRES_555_02A was designed as deeper extension of EX_BRES_555_02 and is being drilled as a re-entry using a higher-capacity drill rig. At the time of this news release, the hole has reached 1,443 metres downhole, equivalent to approximately -600 metres elevation, and continues to intersect the same prospective geological environment encountered at the end of EX_BRES_555_02. Drilling remains in strongly silicified diorite, locally with weak, patchy chlorite alteration, and cut by a network of anhydrite veins and locally intense quartz-pyrite-chalcopyrite veining. Mineralization is characterized by disseminated chalcopyrite and pyrite, with rare bornite-pyrite-clay nests observed in the groundmass. Assay results to date have returned an interval of 37 metres grading 1.19 g/t AuEq (0.53 g/t Au and 0.63% Cu) from 1,357 to 1394 metres downhole. Drillhole EX_BRESPO_04A, designed to test the eastern part of the target area, has now been completed at 1698.5 metres downhole. The hole ended in phyllic alteration, with no visible evidence of potassic alteration observed. Assay results are pending. These results confirm the presence of a significant porphyry system immediately southeast of the Chelopech mine, distinguished by relatively high gold-copper grades for porphyry-style mineralization. The scale of the alteration footprint, the presence of potassic alteration and stockwork veining, and the downhole continuity of mineralization collectively supports the interpretation of a large and vertically extensive porphyry target at BSP. The target remains open and continues to demonstrate strong potential for further expansion. Its proximity to existing Chelopech mine infrastructure highlights its potential to support future mine life extension. Preliminary interpretation of logged alteration assemblages and newly received drilling results, together with existing geophysical data, suggests that the footprint of the BSP target is significantly larger than initially anticipated and continues to expand as drilling progresses. To further define the extent of mineralization at BSP, DPM has planned up to 15,000 metres of additional drilling in 2026 to further appraise the target. In addition to ongoing drilling at BSP, DPM currently has seven additional drill rigs deployed across the Brevene licence area to test multiple target areas. Current work is focused primarily on the Vozdol and Krasta Northeast epithermal targets, as well as the Sharlo Dere porphyry target, located in the northern and northeastern parts of the licence.
