Bench scale pressure leach tests have confirmed the amenability of Birch Lake flotation concentrates to the proprietary Platsol(R) process. High metal extractions were obtained for all of the significant metals of interest except for gold, which yielded a lower recovery than anticipated. These results have been reviewed by Mr. Al Hayden, EHA EHA European Hematology Association EHA Economic History Association EHA Emmanuel Hospital Association EHA Education for All Handicapped Children Act of 1975 EHA Empty Homes Agency EHA English Hockey Association EHA Electrohydrostatic Actuator Engineering Ltd, Toronto. Mr. Hayden is an independent consulting metallurgist to Franconia and an appropriately qualified person under NI 43-101. The Platsol(R) process was developed at Lakefield Research by International PGM Technologies Ltd.

Franconia President Brian Gavin said: "We are very pleased by the positive results of the pressure leach (Platsol(R)) tests. These results confirm that, at the bench scale, flotation methods can be used to produce a concentrate potentially suitable for hydrometallurgical hy·dro·met·al·lur·gy n. The treatment of metal or the separation of metal from ores and ore concentrates by liquid processes, such as leaching, extraction, and precipitation. processing, which further strengthens our belief in the potential economic viability of the Birch Lake project." The results of the flotation and pressure tests will permit more definitive planning of production plant design, metal recoveries, and capital/operating costs. On the basis of these results Franconia intends to re-estimate the resource at Birch Lake (to NI 43-101 standards) and then commission a NI 43-101 compliant independent Preliminary Economic Assessment. This report will include a "scoping-level" economic evaluation, including a cash flow analysis, of the potential viability of the project prior to any eventual preliminary feasibility study. In January of this year Franconia authorized SGS SGS Société Générale de Surveillance SGS Symantec Gateway Security (appliance) SGS School of Graduate Studies SGS Subgrid Scale SGS Singapore Government Securities SGS Shell Global Solutions Lakefield Research of Lakefield, Ontario to proceed with a series of metallurgical tests including flotation and hydrometallurgical tests on a composite sample of more than 200-kilograms of drill core from twelve diamond drill holes at Birch Lake. The composite sample approximates the average grade and mineralogy mineralogy Scientific study of minerals, including their physical properties, chemical composition, internal crystal structure, occurrence and distribution in nature, and origins or conditions of formation. of the estimated 51 million tonnne inferred resource at Birch Lake. Currently the 51 million tonne inferred resource at Birch Lake is estimated to have a grade of 0.675% copper; 0.211% nickel; 0.01% cobalt; 0.216 grams per ton (g/t) gold; 0.972 g/t palladium and 0.46 g/t platinum, at a cut off grade of $25.35 per ton net smelter return (based on hydrometallurgical treatment) using prices of $450/ounce (oz) platinum; $400/oz palladium; $800/oz rhodium rhodium (rō`dēəm), metallic chemical element; symbol Rh; at. no. 45; at. wt. 102.9055; m.p. about 1,966°C;; b.p. 3,727±100°C;; sp. gr. 12.41 at 20°C;; valence +2, +3, +4, +5, or +6. ; $0.90/lb copper; $3.00/lb nickel; $8.00/lb cobalt; $280/oz gold and $4.50/oz silver, generally well below present prices (see NI 43-101 technical report by Roscoe Postle Associates of Toronto, January 2004, available at www.sedar.com).
