TORONTO (miningweekly.com) – The TSX-listed stock of US miner Allied Nevada Gold on Thursday jumped by up to C$0.58 a share to C$4.71 apiece soon after the company released its 2013 full-year and fourth-quarter output results.

Allied Nevada said preliminary results pointed to full-year gold sales rising 59% year-on-year to 181 941 oz, compared with 114 705 oz in 2012. Silver sold in 2013 totalled 858 073 oz, up 23% when compared with the 696 144 oz sold in 2012.

For the fourth quarter ended December 31, the company sold 60 460 oz of gold, a 45% increase over sales of 41 745 oz in the same quarter of 2012.

During last year, Allied Nevada produced 190 831 oz of gold, which was 39% more than the preceding year, when output totalled 136 930 oz of gold. For the fourth quarter, gold output totalled 61 419 oz, 35% more than the 45 613 oz reported in the same quarter of 2012.

Silver output totalled 882 225 oz in 2013, 11% more than the 794 097 oz produced in 2012. For the fourth quarter, silver output totalled 377 314 oz, up 61% over the same period a year earlier, when the company reported 234 129 oz.

"Our record sales and production achieved in 2013 are a credit to the new operating team. We have now grown our heap leach operations and the capabilities of our site management team to a level of competency that gives us the ability to focus on the next phase of the expansion, processing our sulphide material,” president and CEO Randy Buffington said.

Record sales and output levels in both the fourth quarter of 2013 and the full year 2013 were the result of significantly increasing the mining rate and starting-up the company’s new Merrill-Crowe plant in October, which allowed Allied Nevada to process more solution.

In the second half of 2013, the company sold 113 173 oz of gold, just shy of the 114 705 oz sold for the full year in 2012.

Around noon on Thursday the share price had given back some of its gains at C$4.62 a share, a far cry from the C$28.14 shares traded at last January.
