The increased production and reduced cash costs of the second quarter continue in the same positive vein as Q1 and demonstrate the sustainability of operational improvements and cost reductions introduced over recent months. Orosur’s focus on refining its geological modeling suite and optimizing ore control processes at its Arenal Deeps underground mine and in its open pits, as well as an overall reduction in costs, continued in Q2 generating further financial and operational advances.

Additional to the continued improvements in cost and operational performance, the Company is further optimizing its fleet use and is reviewing available options to reduce processing costs and therefore be capable of economically producing from lower grade ore.

ENHANCED OUTLOOK FOR FISCAL 2014

Based on the results achieved year-to-date and the consolidation of the changes introduced positively affecting the remainder of the year, the Company has:

• Increased production guidance to 55,000 - 60,000 oz, an increase of ~10% over the previously stated guidance of 50,000 - 55,000 oz
• Reduced operating cash costs guidance to US$800 - US$875/oz compared to US$850 - US$925/oz as previously stated. The updated costs target is equivalent to a reduction of ~20-27% from the US$1,093/oz operating cash costs reported for FY 2013

Production from the second half of the year is expected to come from ore from Arenal underground and Vaca Muerta open pit.

ADDITION OF 44,189oz OF RESERVES

As announced on November 13, 2013 the Company successfully added 40,000 oz of gold reserves during the quarter and received a feasibility study supporting the employment of pillar-less mining using Cemented Rock Fill at the Arenal Deeps Mine. Based on the updated mine plan, Orosur intends to start mining the first stope using the new pillar-less mining method in March 2014. Cost improvements in other areas offset the minor anticipated costs of cementing the rock fill at Arenal during Q4 2014.

At Vaca Muerta, pre-operational activities were finalized and the exploitation permit was granted on December 6, 2013 with mining scheduled to commence according to plan this current month. A total of 1,796m were drilled at Vaca Muerta during the quarter. The results of this infill drilling campaign increased the mineral reserve by 4,189 oz (from 11,642 oz to 15,831 oz). This represents a cost of approximately US$40/oz of reserve defined. The mineral reserves were optimized at a price of 1,100 US$/oz.

Ignacio Salazar, CEO of the Company commented:

“Orosur is delighted to have achieved another strong set of quarterly operating results. It is with great pride that our team continues to demonstrate the sustainability of robust operating figures realized so swiftly on the back of the focused operational and organizational improvement programmes initiated over the past half year. This performance has enabled Orosur to increase production guidance and reduce unit cost expectations for fiscal 2014. The successful results from our near mine exploration team and subsequent additions to our reserve base is in line with our intention to deliver further improvements both in the short and long term”.
