The takeover rumour mill is working overtime as speculation about the size of Harmony Gold’s Wafi-Golpu deposit increases. Harmony has already been forced to share the planet’s potentially third largest gold and copper mine with Australia’s Newcrest Mining, selling 50% of the project for $525m three years ago. Now, as the value of Wafi-Golpu climbs - Deutsche Bank recently put it at $9.9bn – and predictions of development cost reach $5bn, other suitors may be lining up for the assets. M&A activity in the gold sector is at a 10-year high and top takeover candidates are Harmony’s South African peer Gold Fields, Canada's Barrick Gold, Newmont Mining and partner Newcrest itself.

Baotou Steel Rare Earth (Group) Hi Tech Co, the world's largest rare earth producer, will consolidate 35 local miners this month and further unify the distribution and processing of the 17 elements. The Inner Mongolia autonomous region, the site of 97% of China's reserves, has drafted a plan to concentrate all resources under Baotou. The move follows the announcement last week that the state-owned firm will set up the country's first rare earth products exchange to further regulate the market.

Indian traders on Saturday sent gold prices higher amid the Indian wedding season and firming overseas trends and silver snapped its three-day losing streak. On global markets on Friday Gold for August delivery added $9.70 to $1,542.40 an ounce after US economic data showed job growth slowed to a crawl in May. The weak dollar and the spectre of a return to recession in the US on top of a European debt crisis have buoyed the gold price this year and long term fundamentals – buying in India and China – remain strong. India remained the top purchaser of gold buying 291 tonnes in the first quarter while China added 93 tonnes of bars and coins from January to March, more than double the 2010 level and jewellery demand increased 21% from a year earlier to a record 143 tonnes.

At the other end of the scale prices have also been rising at a rapid rate. Demand for one carat and smaller stones from India and China pushed the International Diamond Exchange's polished diamond index to a new record in May surpassing the previous record level achieved in the pre-recession summer of 2008 and up 12.5% so far this year.
