Barrick Mining has filed a Form S-11 with the US Securities and Exchange Commission to spin out its North American gold assets into American Barrick Gold Corporation, targeting a New York Stock Exchange listing under the ticker ‘ABGC’. The new vehicle will hold Barrick’s US joint-venture interests within Nevada Gold Mines and the high-grade Fourmile discovery in Nevada, plus its stake in Pueblo Viejo, with net IPO proceeds to be upstreamed to Barrick and returned to shareholders. CEO Mark Hill, appointed in August to lead the unit, has cautioned the IPO may slip into January due to regulatory formalities.

Price volatility in lithium, copper, nickel and other critical minerals is causing 23% of otherwise viable projects to be deferred or cancelled and is a dealbreaker for a further 12% of developers, investors and miners in DLA Piper’s 550-respondent survey. More than half see volatility as a major constraint, with 28% unable to secure bankable long-term offtake, 27% postponing investment decisions and 26% facing higher cost of capital, particularly in the UK and US. In response, 37% of developers and 32% of producers are pursuing vertical integration from mine to recycling, while many favour component-linked pricing or long-term fixed contracts with periodic resets over spot benchmarks.

Gunnison Copper has confirmed a high-grade copper-zinc zone at the Strong & Harris deposit in Arizona, with drill hole SHM-2 cutting 94.8 metres at 1.39% Cu and 2.29% Zn from 160 metres depth, including 12.2 metres at 5.15% Cu, 11.99% Zn and 16.38 g/t Ag. The company will run flotation tests on sulphide material to determine recoveries and economics for potential copper and zinc concentrates, as an alternative to the current heap leach–SX–EW flowsheet in its March PEA. Gunnison is already producing copper at nearby Johnson Camp using Rio Tinto’s Nuton leaching technology under an $8 million demonstration agreement running to 2029.
