Red River Resources Limited (ASX:RVR), an Australia-based mineral exploration and development company founded in 2002 and headquartered in Perth, focuses on base and precious metals including copper, lead, zinc, gold, silver, lithium, tin, iron ore and nickel; it previously operated the Thalanga Base Metal Operation in Queensland, featuring a 650ktpa processing plant producing copper, lead and zinc concentrates with gold and silver credits, alongside the Hillgrove Gold Mine in New South Wales and the Herberton silver-indium project in Queensland. The company targets multi-asset production primarily in Australia, serving global base and precious metals markets through concentrate sales. In late 2022, Red River and key subsidiaries including Hillgrove Mines Pty Ltd entered voluntary administration due to solvency concerns; shares were delisted from the ASX on August 29, 2023, with assets such as the Hillgrove project subsequently acquired by Larvotto Resources Limited in December 2023.
