It was also a big day for Apollo Gas, a holder of exploration licences in NSW, which doubled its share price to 40 cents on its debut on the stock exchange. The big miners were also higher, with BHP Billiton up 45 cents at $41.10 and rival miner Rio Tinto adding 34 cents to $70.85. ''The weaker US dollar overnight and broadly higher base metal prices are also seeing our miners back in vogue today,'' Mr Peacock said. ''Whether the apparent easing of the Dubai debt situation and quietening speculation of US rate hikes is enough to reinvigorate the risk trade is yet to be determined.'' Gold stocks were also higher, with Lihir Gold up 4 cents at $3.30 and Newcrest adding 71 cents to $35.89.
