Gypsum industry news

Australia: Mining corporation Rio Tinto has blocked a bid by Australian billionaire Len Buckeridge to win control of its gypsum deposits near Carnarvon, Western Australia by announcing it is restarting its ancillary operations at its mine.

Buckeridge, who is worth an estimated US$2.5bn and runs an integrated industrial empire that is one of the biggest homebuilders in Australia, wrote to the State Government in March 2012, demanding that Rio Tinto either restart its operations in Lake MacLeod near Carnarvon or hand over the gypsum rights to him under state agreements, which demand that companies 'use or lose' their deposits. Buckeridge's company supplies about 7% of the subdued Eastern States plasterboard market and more than half of Western Australia's needs, with CSR the other big producer.

Managing director of Rio's Dampier Salt subsidiary, Denise Goldsworthy, said that it had shuttered its Lake MacLeod gypsum operation because it was not financially viable, but booming demand in Asia, and Buckeridge's approach, had caused a rethink.

"Based on the company's projections of medium-term trends for gypsum, primarily in South-East Asia and Australia, Dampier Salt has decided to commence working through the State Government approvals process to resume its own gypsum mining operation targeted at these markets," Goldsworthy said. Dampier Salt gave no deadline for when gypsum would be mined again at the site.
