VANCOUVER, BC, Dec. 12, 2025 /CNW/ - Soma Gold Corp. (TSXV: SOMA) (WKN: A2P4DU) (OTC: SMAGF) (the "Company" or "Soma") is pleased to announce drill results from the "Cordero Viejo" Zone, located 250 m south of the Cordero Deposit on the Bagre Project in central Colombia (Figure 1). Nineteen diamond drill holes from surface have been completed, totaling 5,587 m (Figure 2). The 2025 drill program was designed to infill historical drilling and to determine the dip and strike extent of the Cordero Viejo vein system.

The deposit extension is hosted by the El Carmen Stock, a composite intrusion comprised of coarse-grained tonalite, diorite, and gabbroic phases, which also hosts the Cordero Deposit. The quartz veins occur as laminated fault-fill veins within a sinistral brittle-ductile shear zone and are interpreted as conjugate shears within a steeply dipping, north-striking regional shear zone. This controlling shear zone also hosts the Los Mangos Deposit, located 3.0 kilometres to the north. The quartz veins at the Cordero Viejo Zone are interpreted to be the next set of en echelon vein segments south of the Atenas Zone at the Cordero Deposit.

The veins have undergone repeated reactivation and display three distinct phases of development: early barren quartz veins, sphalerite + galena + pyrite + gold mineralization controlled by microfractures; and brittle fracturing along vein margins filled with quartz + pyrite + tellurides + gold. Gold mineralization occurs during the latter two phases of vein development. The final stage of brittle fracturing and micro-breccia is commonly associated with pyrite and high-grade gold mineralisation. Subsequently, the veins are crosscut by aphanitic mafic dykes and late brittle faults. The brittle faults in the area generally exhibit dextral strike-slip displacement and offset the quartz veins from less than a metre to tens of metres. These late brittle faults commonly dismember the mineralized veins into short strike-length segments, making continuity difficult to discern from drill data.

Soma's Vice President of Exploration, Chris Buchanan, stated, "Cordero Viejo is south of the Cordero Deposit and outside the 43-101 resource released in 2023 (see news release dated January 5, 2023). The 2025 drill plan incorporated what we have learned about vein geometry and orientation patterns in the Cordero deposit and successfully delineated new veins down dip of the historical workings. We are excited to continue exploration on this vein system and to bring these new resources into the 2026-2027 mine plan."

Table 1 presents the composited assay results from eighteen of the completed drill holes at the Cordero Viejo Zone. Assay results are pending for one of the recently completed drill holes. Assays in the drilling range from below detection to a maximum grade of 23.0 g/t Au. A total of 51 samples were >1.0 g/t Au. The drilling currently covers approximately 518 m of strike length and delineates mineralised quartz veins for approximately 350 m down dip.

A long section of the drill intercepts is presented in Figure 3. The quartz veins form in multiple segments due to their geometry, cross-cutting faults, and late mafic dykes. Underground drilling is ongoing in this area to continue exploring for vein segments down dip from the current mine workings. CDVDDH-25-015 was targeted to test the down plunge extent of what appears to be a south-southeast plunging high-grade ore shoot. The hole intersected three 1.0 to 1.5 m wide quartz veins with high-grade gold values. The widest quartz vein intercept in the hole is 6.6 g/t Au over 1.5 m, including an individual sample of 19.8 g/t Au at a depth of 269.3 m (Plate 1). The true width of this vein is approximately 1.3 m. The extent of the vein segment discovered in this drill hole is currently unknown and will be the target of 2026 infill drilling as the ore shoot is delineated with additional drilling.

The Company intends to continue drilling the Cordero Viejo Mine from surface in 2026. The intent of the Phase 2 drilling will be to improve the confidence level of the resource, test the down-dip extent of the south-southeast plunging ore shoot, and explore for additional down-dip quartz veins to expand the resource.

In addition to supporting mining operations at Cordero Mine, Soma's exploration team continues to evaluate numerous small-scale mines near the El Limon Mine and Machuca Project. The Phase 1 drill program at the Colossa and Colossa 2 informal mines has been completed, and the drill rig is being demobilized to the El Bagre mill complex for preventative maintenance. Additionally, the Company is awaiting the issuance of drill permits for the copper anomaly on the Machuca Project and for the recently acquired Escondida Mine. These targets are scheduled for drilling in late December of 2025 and Q1 2026.

Soma also continues to work with the local communities across the entire property package as part of its ongoing ESG program.

The Otú fault system ("Otú Fault") extends for over 100 km, from Aris's Segovia-Remedios mines (TSX:ARIS) in the south to Nechi in the north, where it is buried beneath younger sedimentary overlap sequences. Soma's property holdings now cover more than 56 km of this regional structure. High-grade gold mineralization occurs in late-stage brittle-ductile to brittle quartz veins along the entire strike length of the Otú Fault. These quartz veins formed during the latest stages of deformation along the Otú Fault. Across the district, quartz veins typically display orientation patterns that suggest they formed in conjugate faults associated with brittle faulting on the Otú Fault. Notable deposits along this trend include: Segovia-Remedios, La Aurora, El Limon, Le Ye, Los Mangos, and Cordero. The Machuca Property is located along a critical segment of this regional fault structure and displays multiple indications of high-grade gold mineralization.

QA/QC Statement

Soma follows a comprehensive QA/QC program to ensure the reliability of assay data collected from its exploration programs. All samples are sawn, or split in half, with one half being returned to the core box for storage. The second half-core is placed in a labelled plastic bag with a tag, document, and sealed for shipment. Batches of samples are shipped to Actlabs Colombia SAS (Actlabs) in Rio Negro with security tags and a documented chain of custody.

Pulps of each sample are prepared in Rio Negro. Pulp samples are then shipped to Actlabs Canada for multi-element analysis. All samples are analyzed using package 1E3, an ICP-MS analysis that provides the concentration of 51 elements. Fire assay analysis for gold and Silver is completed by Actlabs in Rio Negro. Thirty-gram aliquots of each sample are analyzed for gold using a standard fire assay with an atomic absorption finish, package 1A2. Overlimit samples are subjected to an additional fire assay with a gravimetric finish, package 1A3-30, to determine the gold concentration.

A comprehensive QA/QC program has been implemented to monitor the reliability of assay data collected during exploration programs. The program includes the regular insertion of certified blanks, duplicates, and certified OREAS standards. Assays of the QA/QC samples are automatically compared to the certified value and standard deviations in the database.
