SOMA GOLD DISCOVERS NEW VEIN IN UPPER ATENAS ZONE OF THE CORDERO MINE
Soma Gold Corp. has released the results of surface drilling at the Cordero mine in Antioquia, Colombia. Sixteen drill holes have been completed at Atenas, totalling 1,838 m in 2026. The continuing drill program at the Atenas zone is designed to support mining operations and to extend the known extent of the quartz vein system at the upper extent of the Atenas zone.
Highlights include the following drill intercepts:
-
BASDDH-25-038: 15.3 grams per tonne gold over 6.05 metres from 86.5 m, including 60.5 g/t Au over 0.64 m;
-
UATDDH-26-008: 28.2 g/t Au over 3.0 m from 96.7 m, including 167.2 g/t Au over 0.47 m;
-
UATDDH-26-011: 20.6 g/t Au over 3.8 m from 68.75 m, including 94.5 g/t Au over 0.8 m;
-
UATDDH-26-006: 8.0 g/t Au over 3.18 m from 86.2 m, including 25.2 g/t Au over 0.58 m;
-
UATDDH-26-003: 5.9 g/t Au over 3.84 m from 92.7 m, including 16.1 g/t Au over 0.49 m;
-
UATDDH-26-010: 13.7 g/t Au over 1.58 m from 85.65 m, including 34.5 g/t Au over 0.48 m;
-
UATDDH-26-004: 4.6 g/t Au over 3.71 m from 102.9 m, including 21.3 g/t Au over 0.59 m/
Chris Buchanan, Soma's vice-president of exploration, commented: "The discovery of a new high-grade vein zone in the hangingwall of the upper Atenas zone demonstrates that continued infill and exploration drilling will add gold ounces to Cordero's mineral resource. The newly discovered vein lies about 20 m above the current conventional mining operations on the Atenas vein. The exploration team expects the continuing drill programs near the Cordero deposit will identify additional veins like the one in the Atenas zone."
Table 1 presents composite assay results for 14 completed drill holes, with assays pending for two drill holes. Assay grades range from below detection to a maximum grade of 167.2 g/t Au. A total of 811 samples were collected from the core where quartz veins or alteration were observed. Forty-seven samples were greater than 2.5 g/t Au, and 20 were greater than 10 g/t Au. Twenty-nine composites greater than 1.0 g/t Au were identified in the assay data. Composite grades range from 1.0 g/t Au to 28.2 g/t, with a maximum length of 8.55 m.
The drill holes were primarily drilled from the surface and targeted the shallow, updip extent of the Atenas zone. Composite samples plotted on the drill traces indicate that many of the 2026 drill holes intersected two mineralized structures -- the Upper Atenas (UAV) and upper Upper Atenas veins (uUAV). The structurally higher uUAV vein is a new discovery in this area of the Atenas zone. The structures are characterized by milky-white to translucent quartz veins that form as fault-fill veins up to 8.55 m wide and with a true thickness of 6.05 m. Intervals of stockwork zones 10 centimetres to 30 cm thick are also common in the structures. The stockwork zones are interpreted as linking structures between the fault-fill veins. The uUAV vein has a strike length of 175 m and is open to the north-northwest. The dip extent has been established for 30 m downdip and is currently open updip.
Historical drill holes downdip of the uUAV appear to close off the dip extent of the vein. However, a review of core photos and core from a hole immediately downdip of the UATDDH-26-011 revealed a 10-metre interval containing five- to 15-centimetre quartz veins with pyrite, sphalerite and galena that had not been sampled. This interval of sulphide-bearing veins is at the correct depth to be the downhole extension of the uUAV vein, and the hole is currently being resampled. Core photos for the remaining historical holes will be reviewed to identify other potentially unsampled intervals. Although this is not conclusive evidence of gold mineralization, the style of veining in the interval is similar to the mineralized stockwork zones observed in the UATDDH-26-011.
The Cordero deposit is hosted in the El Carmen stock, which consists of coarse-grained tonalite, diorite and gabbroic phases. The quartz veins form as laminated fault-fill veins within a sinistral, brittle-ductile shear zone. They are interpreted as conjugate shears within a steeply dipping, north-striking regional shear zone. The controlling shear zone also hosts the Los Mangos deposit, located 2.8 kilometres to the north. The quartz veins in the Cordero deposit form a series of en echelon segments that consistently step to the right along strike. The veins have been repeatedly reactivated and exhibit three distinct phases of development: early barren quartz veins, sphalerite-plus-galena-plus-pyrite-plus-gold mineralization controlled by microfractures and brittle fracturing along the margins of the veins filled with quartz plus pyrite plus tellurides plus gold. Gold mineralization occurs during the latter two phases of vein development. The final stage of brittle fracturing and microbreccia is commonly associated with the deposition of high gold grades. Subsequently, the veins are crosscut by aphanitic mafic dikes and numerous brittle faults. The brittle faults are generally dextral and offset the quartz veins by less than 1.0 m to tens of metres. The late brittle faults commonly dismember the mineralized veins into short strike-length segments, the continuity of which is difficult to discern from drill data. The Cordero deposit is informally divided into five main zones: Atenas, Cordero, Venus, Venus Gap, and Victoria Ramp zones.
The company continues to actively explore across its Colombian tenement package. At the Cordero deposit, one surface drill rig is testing exploration targets downdip of the Cordero, Atenas and Cordero Viejo zones, while an underground drill rig in the Cordero mine is focused on infill drilling to support mine planning and operations. The company's second surface drill rig continues to drill at the Escondida project. Regional exploration teams are also conducting surface geochemistry sampling programs at the El Bagre and Machuca projects.
Quality assurance/quality control statement
Drill core and underground channel samples
All drill core samples are sawn or split in half, with one-half returned to the core box for storage. The second half-core is placed in a labelled plastic bag with a tag, documented and sealed for shipment. Underground channel samples are placed in a labelled plastic bag with a tag, documented and sealed for shipment with the drill core samples. 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 at the Actlabs Medellin preparation lab in Rio Negro, Colombia. 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 undergo an additional fire assay with a gravimetric finish (package 1A3-30) to determine gold concentration. Pulp samples are then shipped to Actlabs Canada in Ancaster, Ont., for multielement analysis. All samples are analyzed using package 1E3, an ICP-MS analysis that provides the concentration of 51 elements.
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. The database automatically compares QA/QC sample assays with the certified value and standard deviations.
