A 135% increase over Q1 2011 net cash from operations of $3.2 million.Mill throughput for the first quarter was 331,523 tons processed, averaging 3,684 tpd for the period as compared to 291,690 tons (3,277 tpd) in Q1 2011. This is an improvement of approximately 12.5% over the comparable period in 2011.Silver production of 324,375 ounces averaging throughput grades of 1.12 oz/ton for the period. A production improvement of 32% over Q1 2011.Copper production of 2,249,111 pounds averaging throughput grades of .40% for the period. A production improvement of 13% over Q1 2011.There were no lost time accidents reported during Q1 2012. Our MSHA calculated Incidence Rate for Q1 2012 is 2.05 as compared to a national underground average for 2011 (latest available statistic) of 2.21. As at end of March 2012, it has been 400 days, and 419,030 man hours worked since our last lost time accident.Development work continues in the north C Bed decline and production ore is expected to be accessed by August 2012. In addition, pending final state and federal agency approvals, we expect to commence I Bed development in September, 2012. Development of the I Bed mine area will take approximately two years to complete.Production for the first quarter 2012 was approximately 8% below our previously announced guidance of 4,000 tpd primarily due to availability and retrofitting of equipment as we move towards higher bio-fuel usage and meeting revised DPM (diesel particulate matter) emission standards. Lower than planned copper grades were encountered as we advanced top slicing in the C Bed area and as a result of increased lower grade production from the South Ore Body.Taking into consideration adjustments for seasonal factors, along with slight variations of our mine work plan, our 2012 production guidance of 1.4 million ounces of silver and 11.5 million pounds of copper remains unchanged.Troy Production SummaryJanuaryFebruaryMarch1st Quarter 20121stQuarter 2011Mill ProductionMill Feed (st)122,66197,506111,356331,523291,690Mill Feed Rate (stpd)4,0893,3623,5923,6843,277SilverFeed Grade - Oz/Ton Ag0.991.

The Company believes that net cash from operations is a benchmark for performance and is well understood and widely reported in the mining industry. 2. All cash costs include direct mine site costs along with smelting, refining and transportation charges. Average commodity prices used to off-set (by-product credit basis) or allocate (co-product basis) cash costs are the monthly weighted average realized prices based on invoiced shipments. Cash costs per payable ounce of silver or payable pound of copper is a non GAAP measure. The Company believes that, in addition to cost of sales, cash costs per ounce and per pound are a useful and complementary benchmark for performance and is well understood and widely reported in the mining industry. However, cash costs per ounce does not have a standardized meaning prescribed by US GAAP. Investors are cautioned that cash costs per ounce or per pound should not be construed as an alternative to cost of sales determined in accordance with US GAAP as an indicator of performance. The Company's method of calculating cash costs per ounce or per pound may differ from the methods used by other entities and, accordingly, the Company's cash costs per ounce or per pound may not be comparable to similarly titled measures used by other entities.
