DPM Metals Inc. Announces Results from Ongoing Exploration Drilling at the Wedge Zone Deep
DPM Metals Inc. announced results from ongoing exploration drilling at the Wedge Zone Deep (‘WZD’) target, which is located within the northern flank of the Chelopech mine concession and approximately 300 metres below existing Mineral Reserves and current mine infrastructure. Highlights include:EX_WZD_210_01: 68.3 metres grading 7.42 g/t AuEq, comprised of 6.92 g/t Au, 0.30% Cu and 10.50 g/t Ag from 590.7 metres downhole, including 28 metres grading 13.41 g/t AuEq, comprised of 12.78 g/t Au, 0.39% Cu, and 17.75 g/t Ag.EX_WZD_210_01?: 48.1 metres grading 9.41 g/t AuEq, comprised of 8.99 g/t Au, 0.26% Cu and 12.23 g/t Ag from 594.9 metres downhole, including 36 metres grading 11.63 g/t AuEq, comprised of 11.12 g/t Au, 0.31% Cu, and 14.61 g/t Ag.EX_WZD_210_01B: 14 metres grading 13.41 g/t AuEq, comprised of 12.58 g/t Au, 0.51% Cu and 16.57 g/t Ag from 601 metres downhole.EX_WZD_165_01: 40 metres grading 12.40 g/t AuEq, comprised of 11.54 g/t Au, 0.53% Cu and 17.70 g/t Ag from 456 metres downhole, including 31 metres grading 14.84 g/t AuEq, comprised of 13.81 g/t Au, 0.63% Cu, and 19.83 g/t Ag. The WZD target is located within the northern flank of Chelopech mine concession and is situated approximately 300 metres below existing Mineral Reserves and current underground infrastructure. The target volume is a broad corridor of prospective ground that lies below -100m elevation and is located on the hanging wall of the Petrovden Fault, which traverses across the mine concession in an approximate east-west orientation.Deep underground exploration drilling at WZD target started in the first quarter of 2025, designed to follow up on opportunities generated by targeting initiatives with the goal of testing the exploration potential at depth within the Chelopech mine concession. The discovery of the high-grade mineralization encountered in drillhole EX_WZD_210_01 was made by following up on initial scout holes conducted in the vicinity of the WZD target. To date, 3,120 metres from four drillholes have been completed on the newly discovered target, with a further two holes ongoing. The newly discovered zone is presented as a broad interval of high-sulphidation type mineralization documented over a length of approximately 150 metres downhole. It is located within an envelope of advanced argillic alteration and hosted within diorite and phreato-magmatic breccias controlled by northwest-southeast and east-west structures that are in close-proximity of the bounding Petrovden fault zone. The mineralization manifests as wide and continuous zones of massive sulphides that gradually transition to hydrothermal breccia, and then to sulphide stockworks with disseminated and mottled pyrite and copper sulphosalts. The mineralization style is analogous to other mineralized zones found on the periphery of the mine and is expected to have similar metallurgical characteristics. The intercepted mineralization has been outlined in four drillholes to date over a strike length of approximately 110 metres. The mineralization remains open in multiple directions, both along strike as well as down and up-dip, offering strong potential for expansion. Historically, such deeper levels on the northern flank of the Chelopech mine were considered low exploration priority and were subject to very limited attention. As a result, very sparse drilling exists in this area of the Chelopech mine. This significant discovery, which was made in a relatively underexplored and deep area of the mine concession, demonstrates that the WZD target is highly prospective for additional discoveries and supports DPM’s target of extending Chelopech’s mine life to over 10 years. Given the significance of the discovery, the Company is allocating approximately $2 million to $3 million for 10,000 metres of infill and additional delineation drilling for the WZD target, which are expected to be drilled by the end of the first quarter 2026. The planned drilling will focus on assessing the geometry, grade continuity and mineral resource potential of the WZD target.Further to this, DPM is also evaluating options for the development of underground infrastructure to support exploration drilling plans in this region of the mine. Most underground exploration diamond drill holes are collared with HQ size, continued and finished with NQ. Triple tube core barrels and short runs are used whenever possible to improve recovery. All drill core is cut lengthwise into two halves using a diamond saw; one half is sampled for assaying, and the other half is retained in core trays. The common length for sample intervals within mineralized zones is one metre. Weights of drill core samples range from three to eight kilograms, depending on the size of core, rock type, and recovery. A numbered tag is placed into each sample bag, and the samples are grouped into batches for laboratory submissions.Drill core samples are shipped to the Company’s own exploration laboratory in Bor, Serbia, which is managed by SGS Minerals (‘SGS’). Quality control samples, comprising certified reference materials, blanks, and field duplicates, are inserted into each batch of samples and locations for crushed duplicates and pulp replicates are specified. All drill core and quality control samples are tabulated on sample submission forms that specify sample preparation procedures and codes for analytical methods. For internal quality control, the laboratory includes its own quality control samples comprising certified reference materials, blanks and pulp duplicates. All quality assurance and quality control (‘QAQC’) monitoring data are reviewed and signed off by an independent QAQC geologist. Chain of custody records are maintained from sample shipments to the laboratory until analyses are completed and remaining sample materials are returned to the Company. The chain of custody is transferred from the Company to SGS at the laboratory door.At the SGS Bor laboratory, the submitted drill core samples are dried at 105°C for a minimum of 12 hours, and then jaw crushed to about 80% passing 4 millimetres. Sample preparation duplicates are created by riffle splitting crushed samples on a 1 in 20 basis. Larger samples are riffle split prior to pulverizing, whereas smaller samples are pulverized entirely. Pulverizing specifications are 90% passing 75 microns. Gold analyses are done using a conventional 50-gram fire assay and atomic absorption spectrometry (‘AAS’) finish. Multi-element analyses for 49 elements, including Ag, Cu, Mo, As, Bi, Pb, Sb, and Zn, are done using a four-acid digestion and an ICP-MS finish. Samples returning over 10 ppm for Ag and 1% for Cu, Pb and Zn are re-analyzed using high grade methods with AAS. Sulphur is analyzed using an Eltra Analyzer equipped with an induction furnace.
