Defiance Silver Receives Approval for up to 172 Drill Sites at Espiritu Copper Target, Sonora
Defiance’s SEMARNAT permits for 172 drill sites at Espiritu advance its Green Earth portfolio.
Defiance Silver Corp. (DEF) received environmental authorization from Mexico's SEMARNAT for the Espiritu target at its Green Earth Project on August 5, 2026. The Informe Preventivo approval permits exploration drilling and infrastructure construction for approximately 60 months. Authorized activities include constructing up to 172 drill platforms and related access roads.
This development follows a pattern of securing permits for other Green Earth targets, such as the Victoria target approved in February 2026.
Defiance Silver Corp. (DEF) has secured a standard regulatory approval, a routine milestone for an exploration-stage company operating in Mexico. This permit unlocks the ability to execute the planned work program at the Espiritu property, aligning with the company’s stated exploration roadmap.
The approval does not alter the fundamental financial outlook, valuation, or risk profile of the company. There is no immediate revenue or cash flow impact, as Defiance Silver continues to burn cash on exploration and corporate overhead. Consequently, the market reaction is likely to be muted, as permitting is a prerequisite rather than a value-creating event in itself.
Defiance Silver Corp. (DEF) is a Canadian exploration and development company focused on silver, gold, and copper assets in Mexico.

Management is led by Executive Chairman and CEO Chris Wright, with George Cavey, P.Geo., serving as Vice-President of Exploration and Qualified Person. The company’s strategy involves consolidating 100% ownership of core assets, advancing exploration drilling programs, and delivering updated mineral resource estimates to unlock shareholder value.
