08:16 AM EDT, 03/13/2019 (MT Newswires) -- Alio Gold (ALO.TO) on Wednesday said its fourth-quarter loss widened as costs jumped despite higher gold and silver and gold production.

The company said it lost $16.84 million, or $0.20 per share, compared to a loss of $2.85 million, or $0.06, in the fourth quarter of 2017. Revenue rose 31% to $27.02 million but production costs more than doubled to $40.46 million from $16.86 million.

Alio said the rise in costs came on higher costs at its Florida Canyon mine and lower quality ores at its San Francisco mine, which pushed up processing costs. .

The company's gold sales rose 34% to 21,985 ounces.

Alio shares closed Tuesday up $0.01 to $1.12 on the Toronto Stock Exchange.
