Orosur Mining Regulatory News (OMI)

10 Sep 2013 07:00

Orosur Mining Inc. (the "Company") (TSX:OMI) (LSE:OMI) is pleased to announce that production for its first quarter ending 31 August 2013 was 16,851 ounces of gold, significantly ahead of the Company’s previous guidance of some 13,500 to 14,500 ounces of gold.

These ounces were produced at an average cash operating cost of US$ 755 per ounce, compared to previous guidance of US$950 to US$1,000 per ounce of gold for the quarter. When compared to the same quarter last year, production is 9% higher and costs 30 % lower (Q1, Aug 2012: 15,451 ounces of gold produced at average cash operating cost of US$1,094 per ounce).

The increased production and reduction in cash costs have been achieved primarily due to operational improvements and cost reduction programmes initiated and implemented over the recent months. The Company’s focus on refining our geological modeling suite and optimizing ore control processes at the Arenal Deeps underground mine and in the open pits, as well as an overall reduction in costs, continued in the quarter generating further financial and operational advances.

The Company is optimizing fleet use, improving maintenance and availability and continues to focus on the ongoing productivity of its mines. Production of higher grade ore from the tranverse stopes of Arenal Deeps, which commenced at the end of April 2013, yielded stronger than anticipated production for the quarter, and will be key in order for the Company to sustain results of this calibre. Additionally, a stronger than expected US dollar exchange rate (12% appreciation in the quarter) helped mitigate Uruguayan pesos denominated expenditure.

The Company maintains its production forecast for FY2014 of 50,000 to 55,000 ounces of gold at operating cash costs of approximately US$850 to US$925 per ounce of gold. This is equivalent to a reduction of approximately 20% from the US$1,093 per ounce operating cash costs reported for FY2013. Should the first quarter trend continue, additional benefits may accrue from operational improvement programmes and may allow Orosur to perform above current forecasts.

Ignacio Salazar, CEO of the Company said:

“Orosur is delighted to have achieved such a strong set of quarterly operating results. It is a pleasure to see robust operating figures realized so swiftly on the back of the focused operational and organizational improvement programmes initiated over the recent months. The Company continues to strive to achieve further improvements both in the short and long term”.
