Interview with Peter Akerley, CEO & Kelly Clure, Advisor of Erdene Resource Development Our previous interview: https://www.cruxinvestor.com/posts/erdene-resource-developments-tsxerd-undervalued-investment-series-with-peter-akerley-10566 Recording date: 1st September 2026 Erdene Resource Development Corp. (TSX:ERD; MSE:ERDN; OTCQX:ERDCF) has moved from mine-builder to self-funded explorer. The company's Bayan Khundii Gold Mine, operated as a 50/50 joint venture with Mongolian Mining Corporation, delivered 11,709 ounces of gold in Q2 2026, a 37% increase quarter-on-quarter, generating $53 million in gross revenue. Feed grade rose 25% to 2.4 g/t gold, with recoveries of 96%, ahead of plan. That cash flow is now being redeployed into a materially more aggressive exploration program across the company's broader Khundii Minerals District, discovered by Erdene in Mongolia's southwest. Management has committed 12,000 metres of drilling to Bayan Khundii's western expansion, targeting the corridor between the current pit and the newly resource-defined Ulaan deposit. In parallel, the company is testing porphyry copper potential beneath all three of its main hydrothermal systems, Bayan Khundii, Altan Nar and Zuun Mod, none of which has been drill-tested below roughly 700 metres, despite kilometre-scale surface alteration footprints comparable to major regional discoveries like Oyu Tolgoi. Zuun Mod, a wholly-owned molybdenum-copper porphyry, is the standout near-term catalyst: the deposit ranks in the upper 15th percentile globally on grade-tonnage terms, and a preliminary economic assessment is on track for mid-H2 2026, backed by a newly contracted deep geophysics (IP/MT) program aimed at both Zuun Mod itself and the adjacent Khuvyn Khar copper target. Altan Nar, holding roughly 500,000 ounces of gold along a 5-kilometre trend, is next in line for 2027 capital, with management weighing a CIP tie-in to the existing Bayan Khundii plant against a standalone flotation-concentrate build. Early metallurgical work favours the CIP route, potentially adding five years of mine life for a fraction of the estimated $140 million standalone capex. A complementary heap leach study, covering oxide material at both Dark Horse and Altan Nar, could add a further ~100,000 ounces of lower-cost production. A smaller, earlier-stage option property, Tereg Uul, sits roughly 10km south of Oyu Tolgoi; a maiden drill program confirmed anomalous gold, silver and native copper along a 1.5-kilometre structure, and the option was extended in July 2026 with a $400,000 payment. Underpinning the exploration push is a policy tailwind: Mongolia's mining ministry announced in June 2026 that it would reopen exploration licensing after roughly a decade of restricted issuance, a development management believes favours first movers with existing geological databases, including Erdene. Financially, the company holds $26 million in corporate cash earmarked for its wholly-owned project pipeline through 2027, and is running an active share buyback (up to 4.9 million shares, ~10% of public float, with 94,400 shares already repurchased at an average $5.21). Key near-term catalysts for investors to track include the Zuun Mod PEA, deep geophysics results expected later in Q3 2026, and progress on Mongolia's licensing reopening.
