May 2009 Update
  • Underground development for the month of May stands at 154.2 metres; ore tonnage produced was 9,036 metric tonnes (tm) in the cut & fill stopes and ore moved to the mill was 15,136 tm.
  • Mexican cash operating costs(1) for mining, milling and administration for May 2009, were US$37.98 per tonne (budgeted US$44.66 per tonne).
  • The Company completed a surface stockpile sampling/surveying program to evaluate the metal content and value of the stockpiled Candelaria mine development ore. Results indicate that approximately 4,200 tm of broken ore is currently available at an estimated grade of 155 g/t Ag, 0.27% Cu, 1.00% Pb and 1.96% Zn. The estimated NSR value of this material is considered similar to average mine grade. This material is expected to be hauled to the mill within the next few months and blended with the Nuestra Senora mined ore stockpile.
  • Mill throughput in May reached 15,387 tonnes (budgeted 12,000 tonnes) for the 21 days of milling, or 733 tonnes per day.
  • Recoveries at the mill were 86.7% for silver (83.5% budgeted), 69.1% for lead (78.5% budgeted), 53.3% for copper (50% budgeted) and 68.8% for zinc (79% budgeted). Modifications of the mill circuit to improve copper recovery caused slight decreases in lead and zinc recoveries. Further modifications have now been completed and recoveries for these metals have returned to normal.
  • High-grade mine ore processed totalled 11,463 tonnes and was mixed at a 3:1 ratio with lower-grade development ore. At month end, total stockpiled ore was 38,121 tonnes including 28,225 tonnes of development ore in stockpile #1 and 9,896 tonnes of high-grade ore in stockpile #2.
  • A total of 45,214 ounces of silver were recovered for the month in addition to lead, zinc, copper credits.
  • A total of 83,997 ounces of silver were shipped / sold for the month in addition to lead, zinc, and copper credits.
  • Under the existing off-take contract which is in effect until October 2009, the Company shipped 312 tonnes of copper concentrates and 414 tonnes of zinc concentrates to the loading facility in Manzanillo, México. It also delivered 352 tonnes of lead concentrate to the Peñoles smelter facility in Torreon, México under its current contract which will expire June 30th, 2009.
  • The Company, through its concentrate brokers, has concluded negotiations with Peñoles for a further one year contract to smelt the lead concentrate at the Torreon smelter. The new contract is effective July 1st, 2009 and under the terms of the contract the company will supply a minimum of 200 tonnes of concentrate per month.
  • On March 30, 2009, an underground diamond drilling program was initiated to better define future high-grade cut and fill stopes. The program was completed on May 29th and totalled 1,073 metres. Assays remain pending for most of the holes although based on visual assessments (which remain subject to assay analysis) significant additional tonnage is expected in the M-01 Zone (Level 9) and the Santa Teresa Zone (Level 9.5). Further diamond drilling will be scheduled depending on grade control and mine planning requirements at the mine.
  • The Company continues to aggressively look at near term development and/or operating mining assets located in Mexico for possible acquisition.

(1) Cash operating costs per tonne is a non GAAP measure. The Company believes that, in addition to cost of sales, cash operating costs per tonne is a useful and complementary benchmark for performance and is well understood and widely reported in the silver mining industry. However, cash operating costs per tonne does not have a standardized meaning prescribed by Canadian GAAP. Investors are cautioned that cash operating costs per tonne should not be construed as an alternative to cost of sales determined in accordance with Canadian GAAP as an indicator of performance. The Company's method of calculating cash costs per tonne may differ from the methods used by other entities and, accordingly, the Company's cash operating costs per tonne may not be comparable to similarly titled measures used by other entities. Cash operating costs per tonne is calculated as the cost of sales adjusted for change in inventories.
