Red River Resources Limited (ASX:RVR), a mineral exploration and development company, focuses on base and precious metals projects in Australia, including copper, lead, zinc, gold, silver, and antimony deposits; it operates the Thalanga Base Metal Operation in Queensland producing copper, lead, and zinc concentrates from the Far West Mine; and the Hillgrove Gold Mine in New South Wales targeting high-grade gold and antimony resources. The company holds a 100% interest in the Thalanga project near Charters Towers, Queensland, and interests in the Hillgrove project near Armidale, New South Wales, serving markets in base metals and precious metals through concentrate production and exploration activities. Founded in 2002 and headquartered in Melbourne, Australia, with operations in Queensland and New South Wales, Red River Resources entered voluntary administration in November 2022 amid solvency concerns related to its Thalanga operations and creditor obligations, including to Trafigura; its shares were suspended and ultimately delisted from the ASX on August 29, 2023, following failed recapitalization efforts and creditor meetings that led to the liquidation of certain subsidiaries like Hillgrove Mines Pty Ltd, whose assets were acquired by Larvotto Resources Limited in late 2023 for $8 million.
