01:26 PM EDT, 09/10/2018 (MT Newswires) -- RNC Minerals (RNC.TO) more than doubled in heavy trading after the company said on Monday as single 130-tonne sample from its Beta Hunt Mine in Australia yielded 9,250 ounces of gold and said it is now mulling a sale of the company.

The company said the sample, a single, 44 square-meter cut from the mine's 15 level, produced to equivalent of 2,200 grams of gold per tonne, while its gold is expected to sell for $15 million.

"Recovering 9,250 ounces of high grade coarse gold from a single cut on the 15 level at our Beta Hunt mine, including specimens which could rank among the largest ever discovered, underlines the importance of this discovery," Mark Selby, the company's chief executive, said in a statement. "Just 8 weeks earlier, at the end of June 2018, 1,500 ounces of high grade gold were recovered from other sediment structures on the 14 and 15 levels. These discoveries highlight the high-grade gold potential of Beta Hunt."

RNC said it is considering putting itself sale to maximize the value of the mine and has ended talks with a single would-be buyer.

"Given the significance of this discovery to the exploration potential and value of Beta Hunt, RNC has decided to consider all alternatives, including a sale, to maximize the value of Beta Hunt for RNC shareholders," it said in a statement.
