Ignacio Salazar, Interim Managing Director, commented:

"In this quarter, the Company has completed the ramp at Arenal Deeps, production and costs have been brought in line with expectations, we have identified high priority drill targets at Anillo to start drilling in May and have been re-evaluating Quebrada Pantanillo as a high sulfidation gold system to improve the economics of the project. All of this is in line with our strategy to optimise returns to shareholders".

Financial Performance

  • Cash flow from operations for the quarter was US$ 8.0 million and $US 16.6 million for the year to date, compared to US$ 6.8 million and $US 17.0 million for the corresponding quarter and year to date of the prior financial year
  • The Company's cash balance at 28th February 2013 of US$ 5.2 million compared to $US 3.8 million at 30th November 2012 and $US 11.4 million at 31 May 2012. This is in line with expectations. The Company has US$ 6.5 million of committed but unutilized lines of credit available and it is not planning to use them within the current plans of developments and gold price assumptions.

Production and Costs

  • Production for the quarter increased by 34.6 per cent year on year to 18,401 ounces (Q3 2012: 13,668 ounces). 47,822 ounces were produced during the three quarters (3Qs 2012: 38,071 ounces), an increase of 25.6 per cent.
  • Cash operating costs for the quarter were $US 999 per ounce compared to $US 1,104 during the corresponding quarter of the prior year. Year to date, costs are $ 1,093 per ounce compared to $ 1,020 in the prior year.
  • Production and cash costs have been improving and are in line with expectations this quarter despite having encountered some operational issues in the open pits which are not yet completely resolved:
    • The grade of ore mined from the Crucera pit during the quarter improved due to a more appropriate mining approach and improved ore control practices. The reconciliation of ounces produced from open pits compared to reserve models showed both positive and negative variances to plan during the quarter. To reduce this variability an experienced geologist has been recruited to fill the vacant mine geology superintendent position. Increased focus is being put on in-pit mapping, geological modeling and additional infill drilling where necessary in order to improve reconciliations and provide increased certainty on reserves.
    • Lower than planned availability of the large open pit fleet was experienced during the quarter. A number of initiatives have been taken to improve performance. The maintenance department has been restructured and commencement of the San Gregorio open pit expansion project delayed to allow time for major component changes to be completed. These initiatives have already started to show improvements. The Company also plans to purchase a new excavator for the large fleet in the first quarter of 2013/14 to improve productivity.
  • Development of the ramp at Arenal Deeps was completed during the quarter, with ore production targeted for April when level development for the initial mining levels is complete.
  • The production forecast for the full year remains on track to be in the range of 63,000 to 68,000 ounces. A stronger production from Arenal in the final quarter as development will transition from waste to ore and higher grade Arenal ore is the key to reach this target.

Exploration Chile

  • Anillo - successful completion of CSAMT (Controlled Source Audio-frequency Magneto Telluric) survey, to pinpoint the location of sub-vertical silica-bearing structures which may host economic gold-silver mineralization. The Company will commence drill testing the highest priority targets in May, 2013.
  • Pantanillo - new geological mapping and sampling has confirmed the evidence of a high sulfidation gold system under a steam heated zone at Quebrada Pantanillo. Additional activities over the last 6 months have been focused on the evaluation of new, potentially higher grade, exploration targets that lie outside of the existing mineral resource. This potential high sulfidation gold system is located approximately 4 kilometres East-Southeast of Pantanillo Norte where the Company has defined a maiden National Instrument 43-101 measured and indicated mineral resource of 47 million tonnes at 0.69 grams of gold per tonne for 1.05 Million ounces of gold. The Company is currently evaluating the next summer campaign including geophysics and drilling at the new areas is expected to start in November 2013.

Exploration Uruguay Brownfield

During the first half of 2012/13, 44 drill holes equal to 4,530 meters were completed at the Mahoma project (approximately 400 kilometres from the San Gregorio mine). This included 1,560 metres of diamond drilling and 2,970 metres of reverse circulation drilling (of which 1,830 meters were for pre-collars). Assay results received for the final 9 holes during the quarter are shown in the table below.

An NI-43-101 compliant resource is planned to be announced over the next two months with the final report expected to be lodged subsequently. Following the completion of this resource estimate, the Company anticipates the commencement of a mining feasibility study which assumes ore being trucked to the San Gregorio operation for processing.

The table below shows only the holes which had mineralized intercepts.

At Sobresaliente (6 kilometers from the mine), 14 holes for 1,444 meters of drilling were completed during the quarter with the objective of expanding resources and reserves. Drilling confirmed the existence of good grades and widths beneath the currently planned pit at Sobresaliente north. Drilling intercepts are reported in the following table.

At Argentinita (29 kilometers from the mine), 11 holes for 2,087 meters were drilled during the quarter to investigate the potential to expand underground resources. The partial (not all intercepts tested) results of 7 out of the 11 holes below show the potential for extensions to mineralization, and follow-up drilling will be required to define resources in these zones.
