Blackstone Minerals Limited (ASX:BSX) is an Australia-based mineral exploration and development company focused on battery metals and base metals projects in Southeast Asia and North America. The company explores and develops nickel, cobalt, copper, gold, PGE, silver, and manganese deposits; its core assets include the Ta Khoa nickel-copper-PGE project and associated Ta Khoa Refinery in northern Vietnam for producing NCM precursor products for the lithium-ion battery industry, the Mankayan copper-gold porphyry project in the Philippines, and the Gold Bridge gold-silver project in British Columbia, Canada. Blackstone Minerals operates across Australia, Vietnam, the Philippines, and Canada; it was founded in 2016 and is headquartered in West Perth, Australia.
In July 2025, Blackstone Minerals completed a $22.6 million placement to fund 50,000 meters of diamond drilling, geophysics surveys, and metallurgical studies at the Mankayan project, marking a pivotal expansion phase; the company advanced toward vertically integrated low-carbon production following its prior merger with IDM International that consolidated control of Ta Khoa and Mankayan assets.
