| Silver Hart Mine TM Pit Trench Sample Results Vancouver, B.C.: CMC Metals Ltd. (the "Company") is pleased to release the surface trench sample results from the TM pit. Three new veins have been identified, mapped and sampled. Surface sampling of TR08-01 occurred every 20 metres, and TR08-02 and TR08-03 occurred every 10 metres. The following are the finalized assay results:
ACME Analytical Laboratories Ltd. in Vancouver conducted sample preparation and analysis. Sample analysis was by 7AR digest, and analyzed by ICP-ES method. Silver results are by fire assay and gravimetric finish. Standard samples and blanks were used for quality assurance and quality control for sample analysis. Width is horizontal sample interval and does not take into account vein dip. Based on the historical sample data from the underground channel samples, two of the three veins were intersected 23 metres below by the underground workings. Very similar grades and thicknesses were sampled and show a strong continuity to these high grade veins. Don Wedman P.Eng., CEO and President of the Company commented "We are very please with the additional find of these new veins in the TM pit. As we are well underway to developing the TM pit, the immediate value of these high grade veins will benefit the investor's in the early start-up stage of the Silver Hart project." About the Silver Hart Mine Project CMC's 100% owned Silver Hart Mine project is for a 20,000 tonne per year mine and an 80 tonne per day mill facility to concentrate the run-of-mine ore. Mining of the TM and S zone will be on a seasonal basis (June to October) and milling will be on a year round basis. The first two years will be surface mined then continued by underground methods. There has been substantial exploration on the property since the mid-80's. Additional drilling each year occurred by the Company since 2005 to confirm past drill results and to provide the confidence in the substantial amount of historical data. A historic resource estimate (F. Smith, 1988) was determined at the end of 1987 for the TM zone and in addition to the reported historical reserves, the Company speculates an additional volume of 33,225 tonnes (36,609 tons) with an average grade of 1,755 grams/tonne (51.2 oz/ton) silver, totaling 58,310 kg (1,874,937 ounces) of silver.* These historic resource estimates were based on 50 diamond drill holes (3658m, 12,000 feet) and 673m (2208 feet) of underground workings. The Company performed infill drilling and hole twinning as a due diligence to confirm the historical data. An updated detailed mining approach and review of the geological data provided input for the economic model to assess mine dilution, cut-off grades, run-of-mine head grades, and minimum mining widths. For further understanding of the property, the Company had SGS Lakefield Laboratories Ltd. conduct a detailed metallurgical study to define the mineral recoveries, mill flow diagram, and rate of consumption mill reagents need to concentrate the ore. Based on the SGS Lakefield Laboratories Ltd. metallurgical test results, metal recoveries from the raw ore are 96.9% silver, 97.0% lead, and 80.0% zinc by flotation methods.
