Zacatecas Silver Reports High-Grade Gold and Silver Surface Sampling Over 2 km Strike Length at Oso Negro, Sonora

Zacatecas Silver tests high-grade epithermal veins at Oso Negro as permitting nears and cash burn demands near-term capital.

By The Northwire Desk — AI Analysis Jun 09, 2026 · 06:30 ZAC · 0.08 Zacatecas Silver Corp.
Executive Summary
  • Zacatecas Silver Corp. released high-grade gold and silver surface sampling results from its newly acquired Oso Negro project in Sonora, Mexico.
  • Sampling covered a 2 km strike length across three outcropping low sulphidation veins, returning up to 14.8 g/t Au and 2,340 g/t Ag.
  • 39 of 134 vein samples exceeded 1 g/t Au, and 35 exceeded 100 g/t Ag. Eleven samples also showed >1% combined lead and zinc.
  • Geological interpretation indicates samples were collected above the boiling zone of the epithermal system, suggesting higher-grade mineralization remains intact and untested at depth.
  • The company plans to submit a drill permit application to SEMARNAT by the end of June 2026 and will conduct follow-up sampling guided by new multispectral satellite imagery.
  • This follows the definitive option agreement announced on June 8, 2026, to acquire the Oso Negro, Cumaro, La Lola, and Ejutla properties from Heliostar Metals.
Material Impact
  • The sampling results validate the high-grade epithermal potential of the Oso Negro property, which was a cornerstone of the Heliostar portfolio acquisition.
  • The discovery of high-grade intercepts above the boiling zone is a standard but positive geological indicator for epithermal systems, implying upside potential if drilling confirms the model.
  • The news is incremental and expected, serving as a follow-up to the April 16 sampling program and the June 8 option agreement. It does not introduce new financial terms or alter the strategic thesis.
  • The primary material takeaway is the upcoming drill permit submission deadline (end of June 2026), which sets the stage for the next exploration catalyst.
