DPM Metals Extends Mineralization At Dumitru Potok With High-Grade Intercepts

DPM Metals Inc. reported intercepts from drilling at the Dumitru Potok and Rakita North copper-gold-silver prospects, located on the Coka Rakita exploration licence. Drilling extends the marble-hosted intrusive skarn mineralization approximately 90 metres west and 100 metres southwest (drillholes BIDD253 and DPDD037A) and returned encouraging results 300 metres to the north of the Mineral Resource (DPDD039A), indicating further expansion potential at shallow levels. Results demonstrate further growth potential at Dumitru Potok and Rakita North, with mineralization open along strike, laterally and at depth, including priority extensions to the west and southwest of the existing Dumitru Potok Mineral Resource, and to the north and east at Rakita North. These results improve the Company’s understanding of mineralization geometry and indicate mineralized tonnage may be greater than previously modelled. DPM is expanding the 2026 drilling program by an additional 12,000 to 15,000 metres, increasing planned drilling for the year to approximately 32,000 to 35,000 metres. The drilling program will focus on expanding the existing Dumitru Potok Mineral Resource estimate, infill drilling and target testing across the Coka Rakita exploration licence. An updated Dumitru Potok Mineral Resource estimate is expected to be complete by the end of the first quarter of 2027, which will form the basis of a Preliminary Economic Assessment targeted to be complete by the end of 2027. Selected intercepts include: BIDD253: 246 metres grading 1.36% CuEq, comprising 0.67% Cu, 0.69 g/t Au and 4.21 g/t Ag from 1,377 metres downhole, including 26 metres grading 2.07% CuEq, comprising 0.76% Cu, 1.33 g/t Au and 4.48 g/t Ag. BIDD254: 30 metres grading 1.56% CuEq, comprising 0.85% Cu, 0.68 g/t Au and 5.92 g/t Ag from 761 metres downhole, and 29 metres grading 1.29% CuEq, comprising 0.70% Cu, 0.57 g/t Au, and 4.96 g/t Ag from 843 metres downhole. DPDD041: 84 metres grading 2.06% CuEq, comprising 0.71% Cu, 1.37 g/t Au and 4.88 g/t Ag from 1,085 metres downhole, and 51 metres grading 2.17% CuEq, comprising 0.87% Cu, 1.30 g/t Au and 6.20 g/t Ag from 1,320 metres downhole. DPDD042: 50 metres grading 3.68% CuEq, comprising 2.18% Cu, 1.36 g/t Au and 21.75 g/t Ag from 761 metres downhole, including 21 metres grading 5.44% CuEq, comprising 3.80% Cu, 1.33 g/t Au and 37.63 g/t Ag from 772 metres downhole. RADDGTH009C: 76 metres grading 2.66% CuEq, comprising 1.76% Cu, 0.88 g/t Au and 7.30 g/t Ag from 623 metres downhole, including 33 metres grading 3.51% CuEq, comprising 2.40% Cu, 1.07 g/t Au and 9.68 g/t Ag from 655 metres downhole. The intensive exploration program at the Coka Rakita licence, which was initiated in the second quarter of 2026 following the ordinary course renewal of the exploration permit, is proceeding according to plan. The 2026 drilling program is focused on further delineating the full extent of the Mineral Resource reported in late 2025, as well as infill of the high-grade area of the western contact-skarn extension of the known mineralization domain. Results received to date demonstrate potential to expand mineralization along strike and laterally beyond the existing Mineral Resource, while the infill drilling results align well with existing interpretations. Holes BIDD253 and DPDD037A intersected mineralization approximately 90 metres west and 100 metres southwest, respectively, of the existing Mineral Resource. BIDD253 was designed to target marble-hosted mineralization between the Frasen and Dumitru Potok quartz monzodiorite intrusions. The drillhole returned 33 metres grading 1.42% CuEq from 1,003 metres downhole, 52 metres grading 1.61% CuEq from 1,252 metres and 246 metres grading 1.36% CuEq from 1,377 metres downhole, which includes 25 metres of stratabound mineralization at 2.38% CuEq from 1,429 metres downhole, and 26 metres of contact-skarn mineralization at 2.07% CuEq from 1,594 metres downhole. At shallow levels, copper mineralization is dominated by chalcopyrite, with bornite becoming more abundant toward the Dumitru Potok intrusion and locally transitioning to digenite, chalcocite and trace native copper. Near the Frasen intrusion, intensely altered marble hosts mineralization in stockwork veins and karst features, while deeper garnet skarn is strongly replaced by goethite, calcite and silica. Further downhole, drillhole BIDD253 supports a northwest-trending feeder structure at depth that separates iron oxide-hosted mineralization in the hanging wall from bornite-chalcopyrite-chalcocite carbonate replacement-style mineralization in the footwall. To the southwest, DPDD037A intersected several intervals of marble-hosted skarn mineralization, highlighted by 30 metres grading 1.18% CuEq from 701 metres and 21.4 metres grading 0.75% CuEq from 795 metres downhole. These intervals are located approximately 100 metres southwest of the existing Mineral Resource domain. The hole encountered repeated intervals of marble and quartz monzodiorite. At similar depths, drillhole DPDD045, located east of DPDD037A, intersected quartz monzodiorite, suggesting an east-west-trending fault structure between the two holes. The structure is interpreted to have normal and dextral displacement of the intrusion. Additional drilling is planned to refine the geological interpretation in this area. DPDD041, the first infill drillhole to date, was completed on an approximately 50-metre spacing between DPDD026 and DPDD032. Consistent with nearby drillholes, the hole intercepted two zones of skarn mineralization, with an upper interval of stratabound mineralization returning 84 metres grading 2.06% CuEq (0.71% Cu, 1.37 g/t Au, 4.88 g/t Ag) from 1,085 metres downhole, and a lower interval of contact-skarn mineralization returning 51 metres grading 2.17% CuEq (0.87% Cu, 1.30 g/t Au, 6.20 g/t Ag) from 1,320 metres. Drillhole DPDD042 confirmed the northward extension of Cu-Au-Ag stratabound-manto mineralization along the upper marble contact, previously intersected by DPDD028, which returned 36 metres grading 1.50% CuEq (1.13% Cu, 0.29 g/t Au, 8.57 g/t Ag) from 752 metres downhole, with mineralization hosted in dominantly garnet-altered skarn. In contrast, DPDD042 returned a longer and higher-grade intercept of 50 metres grading 3.68% CuEq (2.18% Cu, 1.36 g/t Au, 21.75 g/t Ag) from 761 metres downhole, including 21 metres grading 5.44% CuEq (3.80% Cu, 1.33 g/t Au, 37.63 g/t Ag) from 772 metres. Mineralization consists of chalcopyrite and bornite hosted in garnet, iron-hydroxide, calcite, and silica-altered skarn, with elevated Au and Ag values present in strongly oxidized skarn where primary garnet is intensively replaced by a goethite-calcite assemblage.
