AL17-007 Europa-Guadalupe (one caption for set of 5 photos. Depths are shown in metres. “Europa-Guadalupe vein, close-ups of mineralization. Vein-vein breccia is partly oxidized to chrysocolla (green). Dark grey metallic material is combination of acanthite (AgS), stromeyerite (AgCuS), chalcocite (Cu2S), and galena (PbS). The interval 534.65-542.90 m (8.25 m) averaged 1.76 kg/t Ag, 58 ppb Au, 1.60% Cu, 1.48% Pb, 2.60% Zn.”
AL17-007_NuevaEuropa_IMG_1300 - close up 274.30-274.50m – “close-up of Nueva Europa vein breccia. Note multiple phases of brecciation and quartz-carbonate veining.”
AL17-004_85.25-85.40 “Promontorio vein zone, southern part of Balvaneda vein. Mineralization is partly oxidized to chrysocolla, malachite, and azurite. The sample interval 84.95-85.70 m assayed 229 g/t Ag, 684 ppb Au, 0.55% Cu, 20.22% Pb, and 17.75% Zn.”
AL17-001_79.30-82.18 “Minas Nuevas vein zone. Red outline shows sample Interval 80.45-81.45 m, assaying 279 g/t Ag. Silver appears to be concentrated in dark grey fragments in breccia (blue arrows).”
AL19-025_Promontorio vein zone_AL19-025_463.75-466.50 – “Las Guijas vein, part of Promontorio zone. Vein zone is partly oxidized, with the presence of chrysocolla. The sample interval 463.85-464.80 (0.95 m) (red outline) assayed 1.566 kg/t Ag, 6.719 g/t Au, 4.48% Cu, 9.27 % Pb, 10.68% Zn.”
AL18-012_ Tigre vein zone_DSC_0305 – “Tigre vein zone cut by hole AL18-012. Note quartz-vein matrix of brecciated and epidote-altered volcanic host rock. Sample Interval 203.75-204.35 m (0.60 m) assayed 497 g/t Ag, 0.14% Cu, 0.56% Pb, 0.27% Zn.
AL17-007_NuevaEuropa_IMG_1304 – “Vein breccia of Nueva Europa vein zone. Note quartz-carbonate vein/vein breccia matrix cutting dark greenish-grey andesite. Sample interval 273.30-274.05 m (0.75 m) (in red outline) assayed 694 g/t Ag, 23 ppb Au, 0.34% Cu, 0.63% Pb, 1.30% Zn.”

Underground Rehabilitation and Exploration

Promontorio - Longitudinal section of Promontorio mine showing relationship of workings to January 2026 estimated inferred resource
Promontorio - Balvanera shaft hoist room. Note yellow safety railing around Balvanera shaft collar at center-right of image and gray electrical control panel in center-left background. Orange air duct leads into shaft to provide ventilation. Steel casing slanting from right to left in left foreground contains electrical cable from for lighting and welding and other tools. The wooden beam above the shaft collar is a vestige of historical hoisting equipment.
Promontorio - view down 55 m-deep Balvanera shaft. Note historical timbered shaft walls, recently installed marine ladder and ventilation duct. The ladder reaches 45 m depth and provides access to 3 lower levels at 12, 20, and 45 m.
Promontorio - Portion of Promontorio haulage level with newly installed lighting and water line.
