MELBOURNE, July 28 (Reuters Breakingviews) - BHP (BHP.AX), (BHPB.L) boss Mike Henry is making his own point. He’s avoiding major acquisitions read more in “future facing commodities” such as copper and nickel because of surging commodity prices. Instead, the miner will take a chance on smaller explorer Noront Resources, which has a big claim on Canada’s captivating but undeveloped Ring of Fire. At just C$325 million ($258 million), its proposed deal is hardly indicative of a wild shopping spree. Yet $184 billion BHP is offering a 69% premium to where the shares closed on Monday and 129% more than the price in May before mining magnate Andrew Forrest’s Wyloo Metals unveiled an unsolicited offer. Henry could wind up in a bidding war. Sceptical shareholders erased some $3 billion from BHP’s market value. The sizeable investments required to build roads or rail to reach Noront’s promised deposits have held up development. Projects are further complicated by negotiations with local First Nations. It seems all BHP’s options for new supplies will come at a steep price for the foreseeable future.
