A giant Japanese resources house has thrown its weight behind ASX-listed Hammer Metals in a $6 million joint venture which seeks to unlock further mineral wealth in Queensland’s highly prospective Mt Isa region. JOGMEC is looking to earn 60% of a 290 square kilometre portion of Hammer’s 2,200sqkm Mount Isa project, where the targets are massive IOCG ore bodies similar in style to the giant Ernest Henry deposit.
