Erdene Resource hits first Gold & $30M cash flow

Erdene Resource Development Corporation CEO Peter Akerley joined Steve Darling from the Vancouver Resources Investment Conference to share news about the company’s significant milestone of achieving first gold production and entering the startup cash flow phase. Akerley highlighted that after over two decades of work, reaching this point has delivered a strong sense of achievement for the team, especially with the company now generating substantial early cash flow. "We generated about 30 million US in cash flow in that startup phase," Akerley said, referring to the initial months of production at the Bayan Khundii deposit in Mongolia. Strategically, the production success enables Erdene to unlock the broader potential of what Akerley calls a "great gold district." Exploration efforts are already underway with expansion potential west of the current pit and as far as 2.5km north, where a high-grade surface discovery has been made. Akerley emphasized the company’s community-first approach, operating in a low-population, nomadic region of Mongolia. The company’s partnership with Mongolian Mining Corporation, a 50/50 joint venture, has strengthened relationships with both government and local stakeholders, ensuring a respectful and sustainable approach to development. Looking ahead, Akerley pointed to ongoing drilling at the Dark Horse prospect, a PEA for the My Molybdenum project, and significant infrastructure developments, including access to roads and power to support expanded operations. #proactiveinvestors #erdeneresourcedevelopmetcorporation #tsx #erd #otcqb #erfcf #vric2026 #MongoliaMining #JuniorMining #GoldStocks #MiningNews #MiningInvestment #CashFlow #OTCQX #BayanKhundii
