DPM Metals Announces Inferred Mineral Resource Estimates of 2.6 Million Gold Ounces and 1.9 Billion Pounds of Copper at the Rakita Camp

TORONTO, Dec. 02, 2025 (GLOBE NEWSWIRE) -- DPM Metals Inc. (TSX: DPM, ASX: DPM) (ARBN: 689370894) (“DPM” or “the Company”) is pleased to announce initial Mineral Resource Estimates (“MRE”) for the Dumitru Potok, Rakita North and Frasen prospects in eastern Serbia, all located within one to two kilometres of planned Čoka Rakita infrastructure.

Highlights

• Establishes a potential district scale platform, with a combined Inferred MRE of 84.4 million tonnes at a grade of 0.97 g/t gold and 1.02% copper for 2.6 million ounces of gold and 1.9 billion pounds of copper.
• Dumitru Potok prospect represents a significant higher-grade core of the Inferred MRE. When viewed separately, this prospect comprises 64.1 million tonnes at a grade of 1.07 g/t gold and 1.09% copper for 2.2 million ounces of gold and 1.5 billion pounds of copper.
• Significant exploration potential for continued mineral resource growth at low-cost per-ounce discovery costs, as all three deposits remain open in multiple directions.
• Initial phase of metallurgical testwork indicates high recoveries are achievable, generating a potentially saleable copper and gold concentrate.
• Pathway to low-risk execution, leveraging infrastructure designs based on successful DPM projects, underpinned by DPM’s competitive advantage of 20+ years of in-country experience, for a camp-wide development strategy that accelerates value and growth.
  

“These mineral resources demonstrate the Rakita camp’s potential as a district-scale gold-copper system. Each of Dumitru Potok, Rakita North and Frasen remain open in multiple directions and sit alongside several high-potential targets along a six-kilometre trend,” said David Rae, President and Chief Executive Officer of DPM Metals.

“Since we announced these initial discoveries only 14 months ago, these prospects have rapidly grown into a significant gold-copper Inferred mineral resource, a remarkable achievement over a short period of time which underscores the significant potential of the Rakita camp.

“Together with the result of the Čoka Rakita feasibility study, this confirms the Rakita camp as a Tier One asset for DPM, offering a rare combination of scale, grade and longevity. Further upside potential remains as we test the continuation of the system with step-out drilling on the adjacent licence.”

Inferred Mineral Resource Estimate

The Dumitru Potok, Rakita North and Frasen prospects are located adjacent to the Čoka Rakita deposit and situated on the Company’s Čoka Rakita and Potaj Čuka exploration licenses (Figure 1). The total Inferred MRE is comprised of 2.6 million ounces of gold and 1.9 billion pounds of copper contained within 84.4 million tonnes grading 0.97 g/t gold and 1.02% copper and assumes an underground mining scenario.

Table 1. Dumitru Potok, Rakita North and Frasen Mineral Resource Estimate, effective as of October 23, 2025.

Deposit	Resource Category	Tonnes (Mt)	Gold Grade (g/t)	Contained Gold (K oz.)	Copper Grade (%)	Contained Copper (Mlbs.)
Dumitru Potok	Inferred	64.1	1.07	2,206	1.08	1,535
Rakita North	Inferred	17.9	0.56	320	0.84	331
Frasen	Inferred	2.4	1.21	95	0.70	37
Total	Inferred	84.4	0.97	2,621	1.02	1,903

1. Tonnages are rounded to the nearest 0.1 million tonnes to reflect that this is an estimate.
2. Metal content is rounded to the nearest 1 thousand ounces or 1 million pounds to reflect that this is an estimate.
3. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
4. All blocks include a net smelter revenue (“NSR”) formula that utilises long-term metal prices, metallurgical recoveries, payability terms, treatment charges, refining charges, penalty charges, concentrate transport costs, and royalties.
5. Mineral Resources are reported within MSO shapes generated at a US$50/t NSR cut-off, to ensure Mineral Resources meet reasonable prospects for eventual economic extraction as per CIM Estimation of Mineral Resources and Mineral Reserves Best Practices Guidelines prepared by the CIM Mineral Resource & Mineral Reserve Committee and adopted by the CIM Council on November 29, 2019.
6. The QP is not aware of any legal, political, environmental, or other risk factors that might materially affect the estimate of Mineral Resources.

The cut-off date for the drillhole database was October 23, 2025. The data set includes a total of 194 drillholes, representing 102,550 meters of drilling. In the Dumitru Potok area, current drillhole spacing ranges from approximately 80 metres to 200 metres, while drill density in the Frasen zone ranges from 30 metres to 80 metres. Drillhole spacing in Rakita North is between 80 metres and 150 metres.

Mineral Resource domains were created within areas of logged skarn alteration, guided by economic composites generated using a 0.5% copper-equivalent cut-off value. The underlying geological relationships were honoured by lithological and structural modelling, which was used to control domain geometries and boundaries.

Parent cell block grade estimates for Au, Cu, Ag, Pb, Zn, Mo, Fe, Sb, S, and As, were generated using inverse distance squared interpolation. Mean bulk densities were assigned by lithological unit or mineralized domain. Grade capping was applied to the composite dataset to mitigate the influence of extreme grade values. Given the current drill spacing, a parent cell block size of 50 mE × 50 mN × 5 mZ was utilized, with sub-celling applied to ensure accurate representation of mineralized domain geometries and volumes. A representative cross section though the block model is shown in Figure 2.

A Net Smelter Revenue (“NSR”) calculation has been developed based on initial metallurgical testwork results combined with DPM’s knowledge of potential smelter terms, royalites, onsite and offsite costs. The NSR calculation assumes a payable copper-gold-silver concentrate will be generated, as well as a subordinate zinc concentrate for the Frasen polymetallic prospect. The NSR calculation assumes a copper price of US$4.00 per pound, gold price of US$2,600 per ounce, silver price of US$26 per ounce for all prospects as well as a zinc price of US$2,800 for the Frasen prospect.

The MRE meets the requirements of reasonable prospects for eventual economic extraction (RPEEE) by reporting only material above a US$50 NSR cut-off that falls within the optimized mineable shapes, ensuring mineralization continuity. Optimized shapes use a minimum length constraint of 50 metres, width between 5 metres and 30 metres and a vertical mining height of 5 metres. The reported mineralization exceeds a US$50 NSR cut-off. Any internal or external dilution within the mining shapes is not reported in the MRE. Oxide and transitional mineralization that constitutes the Chocolate South deposit, part of the Timok Gold Project, has been excluded from the estimate.

The MRE was classified as Inferred Mineral Resources, informed by adequate drill spacing, appropriate QA/QC controls ensuring, quality drilling and sampling data, suitable geologic continuity providing, confidence in the geological and mineralization interpretations. Further drilling is required to improve confidence in both the geologic interpretation and the continuity of mineralization.

Prospect Geology

The Dumitru Potok prospect is located approximately one kilometre northeast of Čoka Rakita. The deposit geology is comprised of a sub-vertical, causative monzodiorite intrusive body and the mineralization manifests itself as proximal magnetite-garnet-hematite ± pyroxene copper–gold skarn, along a marble-intrusive contact. The mineralization has an approximate lens-like form, with a 600-metre strike length, is up to 200 metres wide and has been traced over a 400-metre vertical extent.

Away from the intrusion, the Dumitru Potok mineralization continues as a stratabound, manto-like skarn, forming tabular Cu-Au-Ag bodies along a conglomerate-marble unconformity. Mineralization in this zone has been traced for over one kilometer strike length, up to one kilometer away from the causative intrusive with variable thickness, from 5 metres to 40 metres.

The Frasen prospect is a more distal manifestation of the same body, characterised as a tabular zone of manto-like carbonate-hosted replacement and skarn Au-Ag-Cu-Zn-Pb mineralization on the conglomerate-marble contact. The Frasen porphyry, which is not included within this MRE, cuts through the Dumitru Potok zone, hosting well-developed stockwork porphyry gold-copper veins at near surface levels.

The Rakita North prospect is a broad zone of marble-hosted copper-gold-silver mineralization on the northern flank of the Čoka Rakita deposit, located approximately 400 metres below planned underground infrastructure. The mineralization at Rakita North is a combination of manto-like skarn mineralization on the upper and lower contact, as well as more discrete stratabound skarns and structurally controlled subvertical stockwork veins, present over the entire marble lithological package. 

The geology, mineralization and metallurgical characteristics of the prospects are different from the Čoka Rakita project. It is expected to require its own separate project infrastructure for mining and processing.

Metallurgical Testwork Results

Metallurgical testing from representative 30-kilogram composite samples from the Frasen, Dumitru Potok and Rakita North discoveries were sent for testwork during 2025 (Table 2). Testing was undertaken at the Wardell Armstrong International laboratory in the United Kingdom, which is independent of DPM.

Composites BI1, DP1, DP2, DP3 and RA1 were subjected to a preliminary characterization study involving comminution testing, chemical analysis and mineralogical investigation on three size fractions before being subjected to a program of gravity and flotation testing to assess the recovery of copper and gold.   Composites DP4, DP5 and DP6 were subjected to characterization only by chemical analysis and flotation testing to assess the recovery of copper, gold and silver, as part of a subsequent phase of testing.

RA1	Rakita North Skarn	1.17	12.93	0.91	4.86	1.66

Bond ball mill Work Index test classified both the Frasen and Dumitru Potok mineralization as ‘Medium’ with respect to fine ore grinding. With work index for Frasen BI1 of 10.27kWh/t. Work index values of 11.3kWh/t for DP1, 12.44kWh/t for DP2 and 13.27kWh/t for DP3. Knelson gravity testwork showed highly variable gold and copper recoveries. Due to the copper losses and poor gold deportment in the gravity concentrates, further flotation testwork on the Knelson gravity tailings was not undertaken.

Rougher-Cleaner flotation testwork was conducted with various optimization steps employed. Table 3 shows testwork results based on a primary grind p80 of 75μm with subsequent regrind at less than 30μm before a cleaner flotation stage. Although some variability of recovery, grade and mass pull is evident, the preliminary flotation testwork on Dumitru Potok, Rakita North and Frasen composites produced saleable gold-copper concentrate grades between 18% to 39% for copper and 14 g/t to 31 g/t for gold.

DP4	2.71	37.0	21.1	229.5	21.3	60.3	36.6	53.1	61.2
DP5	4.13	39.0	27.4	349.3	10.5	84.9	80.9	73.6	84.8
DP6	4.04	32.1	30.7	176.0	19.4	79.3	72.1	72.1	78.5
RA1	4.25	22.4	14.4	59.6	19.2	82.8	63.0	53.2	49.3

The testwork shows good copper, gold and silver recoveries and significant precious metals credits, indicating that single cleaner stage concentrate would be adequate for conventional smelter marketing. Numerous areas for optimization of the testing conditions were identified during the program, which will be explored during subsequent phases of testing.

Deposits Remain Open for Further Growth Potential

The contact skarn mineralization at the Dumitru Potok prospect remains open to the north, south and partially at depth, whereas the Dumitru Potok stratabound mineralization remains open in numerous locations (Figure 3). At the Rakita North Prospect, mineralization remains open to the south and east. Additionally, at the Frasen prospect, the mineralized horizon is open to the north and south, with opportunity to infill and improve resource definition with further drilling in the main deposit. At a camp scale, DPM has identified numerous porphyry, skarn and carbonate replacement type exploration targets.

Next Steps

Drilling is currently paused on the Čoka Rakita exploration licence pending the normal course renewal of permits, and is anticipated to re-commence in the second quarter 2026. Meanwhile, active drill testing is ongoing at the neighboring Potaj Čuka exploration licence, where further geophysical surveys combined with 20,000 metres of diamond drilling are planned for 2026.

Upon renewal of the permit, the Company has planned 20,000 metres of diamond drilling at the Čoka Rakita exploration licence. A significant component of that drilling will be allocated to infilling and extending mineralization at the Dumitru Potok prospect and increasing the drilling density prior to initiating any Preliminary Economic Assessment or other economic study. Additional metallurgical testwork is planned on samples aligned with the MRE, combined with geometallurgical modelling, to better understand and classify metallurgical variability.

Ongoing Stakeholder Engagement

Consistent with the approach across all operations, DPM seeks to build and maintain strong partnerships with local communities and governments. The Company has had a local presence in Serbia since 2004 and has developed strong relationships in the region and will continue to proactively engage with all stakeholders as the Čoka Rakita project and additional exploration activities advance.

The Company’s approach to advancing the growth potential of the Rakita camp will leverage its proven track record in stakeholder engagement, project development and operational readiness, as well as its proximity to DPM operating mines with readily available access to well-established technical support functions.
