Erdene Expands Mineralization at Zuun Mod Molybedenum-Copper Project

Core Viewpoint - Erdene Resource Development Corporation announced positive drilling results and updates on technical and economic studies at its Zuun Mod molybdenum-copper project, indicating improved mineralization and resource continuity, which will be included in a Preliminary Economic Assessment (PEA) expected in mid-2026 [2][3][10]. Drilling Results - A 3,362-metre drill program was completed, consisting of 24 holes, with significant results from the upper 150 metres of the Zuun Mod deposit, including multiple intersections of high-grade molybdenum and copper mineralization [4][5]. - Notably, hole ZMD-98 intersected nearly continuous mineralization over 374 metres, averaging 0.066% MoEq, and ended in mineralization at a depth of 450 metres [6][8]. Resource Update - The recent drilling results are expected to enhance the mineral resource estimates for the Zuun Mod project, building on the previous update from October 2025, which reported Measured and Indicated resources of 271.1 million tonnes grading 0.056% Mo and 0.064% Cu [7][19]. - The updated resource model will be utilized for the upcoming PEA, which will also include mining studies and metallurgical testwork [9][10]. Infrastructure and Market Conditions - Improved infrastructure in the Khundii Minerals District and strong demand for molybdenum and copper are favorable for the development of the Zuun Mod deposit [3][10]. - The PEA will consider current market conditions and the long-term outlook for molybdenum and copper, with completion targeted for Q3 2026 [9][10]. Khuvyn Khar Copper Discovery - The company is also developing drill targets for the Khuvyn Khar copper discovery, which is part of the same porphyry system as Zuun Mod, indicating potential for further resource expansion [3][11].
