Trigon Metals Mobilizes Drilling Campaign at Addana Project, Morocco

TORONTO--(BUSINESS WIRE)-- Trigon Metals Inc. (TSX-V: TM; OTCPK: PNTZF) (“Trigon” or the “Company”) announces that its inaugural exploration drilling campaign at the Addana Project (“Addana” or the “Project”) in southern Morocco has been mobilized. The program follows the planned work outlined in the Company’s press release dated October 22, 2025.

Highlights

• Twelve (12) diamond drill holes planned for up to 2,100 metres in total
• Target depth per hole: 150–200 metres
• GeoSond Maroc contracted to conduct the drilling
• Core shack to be built and field team identified
• Five holes planned at Antenna Hill and seven holes at Addana Southwest

The Addana Project comprises seven exclusive prospecting permits covering approximately 112 km² in the Addana Mountains, within the province of Tata in southern Morocco. Located near Akka, roughly 300 km southeast of Agadir, the Project is easily accessible via the Agadir–Tata highway and benefits from established local infrastructure. Addana was selected as Trigon’s flagship Moroccan project due to its potential for near-surface, high-grade silver-lead polymetallic mineralization, supported by historic artisanal mining and extensive surface sampling.

Dr. Andreas Rompel, Chief Exploration Officer of Trigon Metals, commented:

“We are excited to turn the conceptual potential of Addana into real drill results. The structural setting and vein geometry suggest there is room to expand vertically and laterally, and this initial drilling campaign is designed to deliver key vectoring information and confidence in continuity at depth.”

Morocco continues to strengthen its position as a mining-friendly jurisdiction with modern infrastructure, clear regulatory frameworks, and a growing profile in precious metals. As global silver prices remain robust, driven by industrial and energy-transition demand, Addana is well-positioned within a region that hosts Africa’s largest silver mine and is emerging as a key destination for new silver discoveries.
