April 2009 Update
  • The Scorpio Mining team has completed a yearly revised budget for 2009 based on the capacity and production done in the first quarter of 2009. The budget was completed along with mine planning which will carry the operation well into 2010 with the actual working areas opened and currently being mined. Balancing ore grade and lower grade material is being done in order to improve efficiency at the mill and the production of metals. Development for the month of April stands at 129.7 metres. Ore tonnage produced was 6,778 tm in the cut & fill stopes and ore moved to the mill was 9,774 tm.
  • Mexican cash operating costs for mining, milling and administration for April 2009, were US$42.62 per tonne (1) (revised budget cost were US$48.33 per tonne).
  • The new up ramp from the main Nuestra Senora Mine access ramp has broken through into the developed Candelaria Mine which is situated approximately 150 metres vertically above the Nuestra Senora deposit. The Company will now resample the high-grade Candelaria surface stock pile and calculate the contained tonnage in preparation for blending this high-grade material with the Nuestra Senora ore. In addition, various mining methods will be evaluated for extraction of ore from the various levels of the Candelaria Mine.
  • In preparation for anticipated future increases in metal prices, the Hoag Zone long hole bulk mining area of the Nuestra Senora deposit now has approximately 73,000 tonnes of ore either broken or drilled off for explosive charges which can be supplied to the mill facility as required.
  • Mill throughput in April reached 12,078 tonnes (new upgraded budget was 12,000 tonnes) for the 17 days of milling, or 710.5 tonnes per day.
  • Recoveries at the mill were 75.1% for lead (78.5% budgeted), 55.3% for copper (50% budgeted), 77.1% for zinc (79% budgeted) and 88.8% for silver (83.5% budgeted).
  • High-grade ore extracted from the Nuestra Senora mine totalled 6,778 tonnes and was mixed at a 3:2 ratio with lower-grade development ore. At month end, total stockpiled ore was 38,373 tonnes including 32,150 tonnes of development ore in stockpile #1 and 6,223 tonnes of high-grade ore in stockpile #2.
  • A total of 38,254 ounces of silver were recovered for the month in addition to lead, zinc and copper credits.
  • A total of 56,561 ounces of silver were shipped for the month in addition to lead, zinc, and copper credits.
  • On May 4th, 2009, Penoles informed the Company that it could resume shipments of lead concentrate to its smelter in Torreon, México following resolution of strike action at the smelter. Under the terms of the current contract, due to expire May 31st, 2009, Penoles and the Company have agreed that the current contract will be extended by one month and will now expire on June 30th, 2009. The Company, through its concentrate brokers, is currently negotiating with Penoles for a one year contract to smelt the lead concentrate at the Torreon facility. The Company recommenced shipments of its lead concentrate to Penoles on May 12th, 2009.
  • The Company completed its commitment to deliver 1,500 wet metric tonnes of zinc concentrate for shipment to a second smelter facility in China in April 2009.
  • The Company has finalized six month (May to October 2009) off-take contracts for its other concentrates of copper and zinc for delivery to the loading facility in Manzanillo, Mexico. These agreements are effective May 14th, 2009.
  • On March 30th, 2009, an underground diamond drilling program was initiated to better define future high-grade cut and fill stopes. These stopes are scheduled for mining in the next few months and will provide more flexibility for mixing with lower-grade stopes and/or assuring constant production when ongoing stopes reach their backfill cycle. During the month of April, a total of 531 metres of drilling was completed with one air drill working one shift per day. Although assays are still pending, the highlight of the ongoing drilling to date was the unexpected continuity of the high-grade silver vein above the current Level 8.
  • The Company continues to aggressively look at near-term development and/or operating mining assets located in Mexico for potential 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.
