Minaurum Gold Inc. is pleased to announce the successful completion of its Phase I -10,000-metre (m) infill maiden resource drill programme and the commencement of a Phase II – approximately 25,000m resource expansion drill programme at the Alamos Silver Project in Sonora, Mexico.
“With Phase I of our resource-definition drilling now complete, we’re excited to move toward a key milestone — the delivery of our inaugural resource estimate,” stated Darrell Rader, President and CEO. “Once we receive assays from the Phase I programme, we will complete the resource estimate. We’re confident that the initial estimate will represent only a fraction of the project’s full potential, as numerous high-priority discoveries remain outside the resource. The 25,000-metre Phase II drill programme is specifically designed to test and expand both existing targets and additional zones toward a major resource update in 2026.”
Minaurum has identified 26 vein zones in an 11km x 6km region covering only one fifth of the Alamos project. Thirteen of the nineteen vein zones drilled returned high-grade silver intercepts demonstrating the abundant mineralisation that occurs throughout the vein zones. Only three of the thirteen discoveries will be included in the initial resource estimate.
Phase I Drilling targeted three high-grade vein zones — Promontorio, Europa, and Travesia — which will form the basis of the inaugural resource. Initial results have been released and continue to demonstrate continuity of high-grade silver mineralisation (see Minaurum news release dated October 16, 2025). Once received, the remaining assays will be incorporated into the resource model in advance of the announcement of the resource estimate.
Phase II Drilling will build on the results of phase I with a planned 25,000 metres of drilling. The programme will include step-out holes at the Europa and Travesia silver shoots, as well as additional drilling at the historic Quintera and Minas Nuevas mines and the more recent discoveries at Promontorio Sur, Cotera, Pulpito, and San Jose vein zones. Minaurum is well positioned to advance this next phase, with 263 drill pads already permitted across the project.
Europa Vein Zone
The cumulative strike length of the vein zone totals 2.8 km and is open more than 1 km along strike to the south and 0.5 km in the northern extension of the vein zone (Figure 2). Average vein thickness is 3.00 m with a grade of 454 g/t AgEq* (358 g/t Ag, 0.5% Cu, 0.6% Pb, 1.2% Zn). Drill targeting will focus on the total strike length and open to depth drilling through multiple hanging wall veins and splays (Figure 2).
Travesia, Promontorio Sur, and Quintera Vein Zones
The cumulative strike length of the vein zones totals 3.2 km and is open more than 1 km along strike which includes more than 5 sub parallel veins (Figure 3). Average vein thickness is 5.40m with a grade of 338g/t AgEq* (170g/t Ag, 0.4% Cu, 1.0% Pb, 2.0% Zn). Drilling at Travesia which is on the hanging wall of the Quintera vein system, will target a high prospectivity zone on stacked vein system as well as the parallel striking historic Quintera mine. Promontorio Sur is the structurally off-set section of the trend with a strike length of 1 km.
Minas Nuevas, San Jose, Pulpito, and Cotera Vein Zones
The cumulative strike length of the vein zones totals 5 km and all are open along strike and at depth (Figures 4-6). Drill targeting will focus on the 1.2 km strike length at Minas Nuevas at the Zambona and Purisima veins, targeting secondary veins that have reported grades through historical drilling. Testing at San Jose will focus on a 1.5 km long section where previous drilling intercepted a wide vein system with secondary veins and splays. Drilling will also test the stacked veins at the Pulpito/Cotera vein zone.
