APPENDIX A: MINERAL PROJECT 1. Property Description And
APPENDIX A: MINERAL PROJECT 1. Property Description and Location (a) The Appia uranium-REE property (the “Property”) comprises a group of 100 unpatented staked mineral claims located in Buckles, Bouck, Beange, Bolger, Gunterman, Joubin and Lehman Townships and near the town of Elliot Lake in north-central Ontario. Elliot Lake is located on Highway 108 approximately 26 km north of Highway 17, also known as the Trans-Canada Highway. The area is situated in UTM zone 17. The geographic co-ordinates of the town of Elliot Lake are 46o23’N latitude and 82o39’W longitude. The Property totals 12,545 hectares (31,000 acres) encompassing five mineralized zones called Teasdale, Banana Lake, Canuc, Bouck Lake and Buckles Lake. The claims have not been surveyed. (b) Appia has a 100% interest in the mineral rights, having initially acquired 61 claims from Canada Enerco Corporation (“CEC”), a related company, under the terms of an agreement dated November 1, 2007. CEC originally staked the claims in accordance with the Mining Act of Ontario. Two claims were transferred to Denison Mines Inc. (“Denison”) in order to permit the construction of a new tailings infrastructure; in exchange Appia acquired the right of access onto claims held by Denison in the Elliot Lake area as well as the right to use former Denison mine workings to facilitate the exploration and development by Appia. Denison granted Appia a 3% net smelter return royalty on any production from the two claims transferred by Appia. Appia purchased 6 claims from Dan Patrie Exploration Ltd. (“Patrie”) in February 2008 and subsequently staked an additional 35 claims. -

Canadian Experience with Uranium Tailings Disposal By: Kb Culver
CANADIAN EXPERIENCE WITH URANIUM TAILINGS DISPOSAL BY: K. B. CULVER - RIO ALGOM LIMITED ay INTRODUCTION; No matter what we produce or manufacture in this world, be it food, clothing, metals, petroleum products or energy, waste is produced as a by-product. The disposal of the waste product may be as technically simple as garbage collection from your household and burial in a land-fill site or as politically complex as irradiated fuel bundles from a nuclear power generation station. In the mining industry this waste product is called tailings, which in simple terms represents finely ground rock from which a large percentage of the economic mineral product has been removed. Unfortunately, the mxneral content of a ton of rock is generally low, so that large quantities of rock must be treated to meet society's requirements. TRANSPARENCY 1 For instance, the Lornex mine, a large open pit copper producer in B.C. recovers 7.5 pounds of copper from each ton of rock. Thus, for each 2,000 pounds milled they must dispose of 1992.5 pounds of rock, or tailings. Since they only recover 90% of the copper, the tailings contain 0.83 pounds of copper. Lornex is currently milling in excess of 80,000 tons/day. A typical gold mine will recover 0.29 ounces of gold per ton of rock treated and disposes 1999.93 pounds of tailings. At the uranium operations in Elliot Lake, approximately 1.6 pounds of uranium are recovered per ton of rock treated and 1998.4 pounds of tailings are disposed. Since only 94% of the uranium is recovered, the tailings contain 0.11 pouiA': . -
