Tenajon's Moly Brook Metallurgy Test Results Confirm High Recovery Rates
Cleaner tests of the high grade composite produced a concentrate averaging 53% Mo
VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 16, 2009) - Tenajon Resources Corp. ("Tenajon" or the "Company") (TSX VENTURE:TJS) is pleased to provide the results of a metallurgical study completed on its Moly Brook Molybdenum Property, located near Grey River, Newfoundland. The purpose of the study, carried out by an independent consulting metallurgical firm, was to:
- Conduct a series of batch rougher and cleaner flotation tests to establish baseline flotation conditions and estimates of metallurgical recoveries; and
- Determine the essential characteristics of the ore composites including the chemical composition and the ore hardness.
The metallurgical study was completed on high and low grade composites of mineralization using core collected from the 2008 drill program conducted at the Moly Brook Zone. The composites respectively weighed 148.1 and 280.2 kilograms. Each composite was stage crushed and screened to pass 6 mesh and split into representative 2 kg charges. Sub-samples were removed from each composite and assayed. The average grades of the composites are summarized below.
------------------------------ Composite Mo (%) Cu (%) ------------------------------ High Grade 0.094 0.045 ------------------------------ Low Grade 0.063 0.019 ------------------------------
The cleaner tests for the high grade composite produced a concentrate averaging 53% molybdenum containing 85% of the molybdenum in the feed. The test work on the low grade composite produced results that were slightly lower compared to the high grade composite. On average about 82% of the molybdenum in the feed was recovered into a flotation concentrate assaying 52% molybdenum. The rougher concentrates were ground to a nominal K80 18 microns prior to two stages of cleaning.
A Bond Work Index test was carried out on the high grade composite and it was found to have a work index of 16 kWh/tonne.
The metallurgical program was carried out by G&T Metallurgical Services of Kamloops, BC under the supervision of Peter Taggart, P.Eng. of Peter Taggart and Associates Ltd., a qualified person as defined by NI 43-101. Mr. Taggart has reviewed this news release and agreed to its contents.
The Moly Brook Property is located on the south coast of Newfoundland, 2.5 km from the hamlet of Grey River, less than 4 km from a deep water, ice free, navigable fjord. The community is serviced daily by provincial ferries.
The Moly Brook Zone, currently the focus of exploration, is located at the north end of a 2.5 km long trend of sheeted quartz veining, stockwork and fracturing in which molybdenum +/- copper +/- silver occurs. Three zones, Moly Brook, Wolf and Chimney Ponds have been outlined in the trend to date. Drilling has traced the Moly Brook Zone along strike for 750 metres depths to over 350 metres below surface. The zone is open to the north and south. Width is variable to 500 metres.
The work at Moly Brook is completed under the supervision of Dave Visagie, P. Geo., a Qualified Person as defined by NI 43-101.
