Castle Minerals Limited (ASX: CDT) is an Australian-based mineral exploration company focused on the discovery and development of gold, base metals, and other critical minerals deposits. The company holds interests in several advanced-stage projects, including the Toorak Gold Project in the Eastern Goldfields of Western Australia, featuring high-grade gold intercepts from recent drilling; the Katgapana Lithium Project in Namibia, targeting lithium-bearing pegmatites; and the Surime Gold Project in Guyana, with potential for open-pit mining. Its services encompass geological mapping, geophysical surveys, reverse circulation and diamond drilling programs, and resource estimation in compliance with JORC standards. Castle Minerals operates primarily in Australia, Namibia, and Guyana, with headquarters in West Perth, Australia, and was founded in 2005.
In the past two years, Castle Minerals has advanced its exploration pipeline through strategic expansions, including the acquisition of additional tenements at the Toorak Project to consolidate its landholding in a proven gold district; a non-binding offtake term sheet with an international gold trader for future production from Toorak; and the commencement of a major drilling campaign at Katgapana following promising lithium assays. The company secured a A$3 million placement to sophisticated investors in late 2024 to fund accelerated exploration; entered a joint venture agreement for base metals potential at its Australian assets; and reported a significant resource upgrade at Surime, elevating its inferred gold ounces. These developments underscore Castle Minerals' shift toward multi-commodity exposure amid rising demand for gold and lithium, positioning it for potential production transitions.
