Table 18-49 REO Shipping to Chicago Avalon Rare Metals Inc. – Thor Lake Project C$/t Pine Point to Hay River 5.00 Load in Hay River In operating costs Rail to Chicago 126.56 Bags 12.00 Pallets 12.00 Cost per tonne of product to Chicago 155.56 For tantalum the shipping is planned to be in 205 l steel drums. The costs of the drums is C$150 per tonne of tantalum product and it is estimated that there will be five pallets per tonne for a cost of C$60/t product. The total shipping cost of the tantalum is estimated to be C$931 per tonne of product as shown in Table 18-50. Table 18-50 Tantalum Shipping to China Avalon Rare Metals Inc. – Thor Lake Project C$/t Pine Point to Hay River 5.00 Load in Hay River In operating cost Rail to Vancouver 91.47 Barrels 750.00 Pallets 60.00 Transfer in Vancouver 10.00 Sea Freight 15.00 Cost per tonne of product 931.47 Scott Wilson RPA notes that these costs are subject to revision as sales contracts are made and as rates for shipping are negotiated with suppliers. Power – Thor Lake Power for the Thor Lake site will be generated with diesel units, the operating costs are based on the generation of 0.27 kW-hr of electrical power per litre of fuel and the installation of power factor management facilities to run a power factor near unity. The annual power generation operating costs are shown in Table 18-51. With six engines installed and their use rotated, Technical Report 43-101 – March 13, 2011 Page 18-129 Prepared by Avalon Rare Metals Inc.
there will be no overhauls in the initial two years. Operating costs include an allowance for the average annual overhaul costs starting in the third year.

Summer Freight The details of the annual summer freight costs are shown in Table 18-52. This cost area includes the annual barge charters for both the docks at Pine Point and Thor Lake, the tug and barge charters for hauling material and the materials handling costs for goods and concentrate at Pine Point and Thor Lake. Materials at Thor Lake will be offloaded and then moved up to the plant site. Technical Report 43-101 – March 13, 2011 Page 18-130 Prepared by Avalon Rare Metals Inc.
