Zacatecas Silver Boosts Esperanza Gold Resource by 21%

Event summary

  • Zacatecas Silver updated its Mineral Resource Estimate for the Esperanza Gold Project, increasing Measured & Indicated resources by 21% to 1.15 Moz AuEq.
  • The project's grades (0.79 g/t AuEq) now exceed global heap-leach averages, positioning it in the upper quartile of comparable operations.
  • Highest grades are concentrated near the surface, supporting a low-capex, open-pit heap-leach development model with 75% gold recovery.
  • P&E Mining Consultants has been engaged to commence a Preliminary Economic Assessment (PEA) for the project.

The big picture

Zacatecas Silver's resource update positions the Esperanza Gold Project as a high-grade, low-cost development opportunity in Mexico's competitive mining landscape. The project's near-surface mineralization and scalable resource base align with industry trends favoring low-capex, oxide heap-leach operations. If the upcoming PEA delivers favorable economics, Esperanza could emerge as a key growth asset for Zacatecas Silver amid rising demand for gold projects with strong development potential.
