Zacatecas Silver has expanded its Oso Negro project in Sonora, Mexico, mapping over 3 kilometres of gold-silver veins with high-grade assays up to 20.3 g/t gold and 3,480 g/t silver. The Prospecto and Tere veins are now drill-ready, with permitting underway for diamond drilling.

This Wire brief sits within Fusion42's coverage of Other.

◆ ◆ The Wire takeaway

You can position yourself ahead of drilling activity in Sonora by engaging with Zacatecas Silver or targeting similar gold-silver vein projects now defined with drill-ready targets. Early involvement offers access to exploration-stage opportunities in a promising low sulphidation epithermal system.
