Rubix Resources Limited (ASX:RB6) is an Australia-based mineral exploration company engaged in the acquisition, exploration and evaluation of resource projects targeting base metals, precious metals and battery minerals. The company holds interests in multiple projects including the Paperbark copper-zinc-lead project near the Gulf of Carpentaria in northwest Queensland; the Redbeds copper-cobalt project northwest of Mount Isa at the southeast end of the Termite Range Fault; the Lake Johnston nickel-copper-PGE-lithium property in the Archaean Lake Johnston greenstone belt in Western Australia; the Etheridge gold project in the Georgetown Inlier of north Queensland; and the Ceiling lithium project in James Bay, Quebec, Canada. It explores for copper, cobalt, nickel, lithium, zinc, lead, gold and platinum group elements across these assets located in proven districts of Australia, Canada and prospective regions in Central Africa. Founded in 2021 and headquartered at Level 11, 216 St Georges Terrace, Perth, Western Australia, the company operates primarily in the metals and mining sector with a focus on critical minerals in tier-1 jurisdictions.
In recent developments, Rubix Resources completed drilling at the Paperbark project and received promising assay results highlighting potential for large-scale copper and lead-zinc systems in the northern Mount Isa Inlier, supported by a A$275,000 government grant. The company signed a non-binding agreement in September 2025 to acquire 100% of prospective bauxite exploration licences in Cameroon (Bangem and Fontem areas) and Congo (Kouyi and Kibangou regions covering 3,000 square kilometres), involving staged payments of A$1.2 million cash and 10 million shares plus performance rights tied to resource definition milestones. These moves strengthen its diversified portfolio with entry into major bauxite regions and ongoing exploration across its Australian and Canadian assets.
