Erdene Expands Mineralization at Zuun Mod Molybedenum-Copper Project
Erdene Pivots to Porphyry as Gold Mine Cash Flow Underpins Massive Moly-Copper Expansion

The February 17, 2026, news release reports drilling results from the 100% owned Zuun Mod Molybdenum-Copper project in Mongolia. Erdene completed 3,362 meters of diamond drilling (24 holes) intended to expand near-surface resources and test the Khuvyn Khar copper discovery. Key results include hole ZMD-98 which intersected 374 meters of 0.066% MoEq and ZMD-162 at the Khuvyn Khar prospect which intersected 65 meters of 0.630% Copper and 2.90 g/t Silver. Management confirmed that these results will be integrated into a Preliminary Economic Assessment (PEA) for the Zuun Mod project, targeted for delivery in mid-2026. This news follows a $25 million financing closed on February 5, 2026.
The impact is Routine - Positive. While the drilling results confirm the continuity and scale of the Zuun Mod system, they are largely in line with the significant resource update provided in late 2025 (which saw a 50% increase in total resources). - Project De-risking: The drilling successfully "ended in mineralization" in several holes (ZMD-98, 147, 148, 152, 153, 156, 157), suggesting the deposit is not yet fully delimited and holds further expansion potential. - Strategic Transition: These results facilitate the company's transition from a single-asset gold producer to a multi-asset, multi-commodity developer. The inclusion of these results in the upcoming PEA is a critical step for project valuation. - Economic Context: Molybdenum is currently viewed as a critical mineral for high-quality steel and green energy, and Zuun Mod is positioned as one of Asia's largest undeveloped resources of the metal. - Validation: The recent $25 million bought deal at $8.90 per share (higher than the current price) indicates institutional appetite for this expansion beyond the core gold mine.
Erdene is a developer/producer focused on the Khundii Minerals District in southwest Mongolia. - Flagship Project (Gold): Bayan Khundii Gold Mine. Commenced production September 14, 2025. It is a high-grade (4 g/t Au) open-pit mine operated via a 50/50 strategic alliance with Mongolian Mining Corporation (MMC). - Flagship Project (Base Metals): Zuun Mod Molybdenum-Copper Project. 100% owned. M&I Resource of 271 Mt @ 0.056% Mo and 0.064% Cu. - Strategic Location: Projects are ~200km from the Chinese border, the world's largest consumer of Molybdenum and Copper.
