Table 18-44 Administration Costs Avalon Rare Metals Inc. – Thor Lake Project 1,000 tpd C$ pa 2,000 tpd C$ pa Labour 1,495,333 1,796,391 Services 3,761,957 5,454,931 Warehouse Labour 339,498 485,958 Freight and Expediting 156,000 300,000 Total 5,752,788 8,037,280 Cost per tonne $15.76 $11.01 Catering at the Thor Lake site is included in the administration costs and is estimated to cost C$41.24 per man day in the camp and the annual caterings costs are C$1.6 million at the 1,000 tpd rate and C$1.8 million at the 2,000 tpd rate. Property taxes are included in the administration costs. Crew transportation costs are included on the basis of Yellowknife as the point of hire for Thor Lake personnel with two charter flights per week between the site and Yellowknife using a Twin Otter aircraft to carry freight and personnel. There is also an allowance for the transportation of some staff to and from locations in southern Canada. Sales and Marketing Sales and marketing costs cover the sales manager and personnel to manage the loading and handling of product in Hay River. There are allowances for sales related travel and activities and an estimate for the cost of freight from Pine Point to a port in China. Product freight costs are based on truck haulage to Hay River and then rail shipment to Vancouver or Chicago. Shipments bound for China would be re-handled in Vancouver and loaded from box cars into containers for shipment by sea. The product shipping cost estimate details are shown in Tables 18-45 and 18-46. Technical Report 43-101 – March 13, 2011 Page 18-125 Prepared by Avalon Rare Metals Inc.
Table 18-45 Sales and Marketing Costs Avalon Rare Metals Inc. – Thor Lake Project 1,000 tpd C$ pa 2,000 tpd C$ pa Administration Staff incl.O/H 220,580 285,191 Travel and Communications 318,000 318,000 Warehouse Staff incl. O/H 169,749 169,749 Freight 3,755,120 7,183,579 Total 4,463,449 7,956,519 Cost per tonne $12.23 $10.90 A summary of the product shipping costs is shown in Table 18-46. The costs are based upon the average concentrate tonnages planned to be generated from the plant at Pine Point. The costs are based on shipping by truck to Hay River where all products will be transferred to rail cars for shipping to either Vancouver or Chicago by rail. Chicago is considered to be one of the delivery points fro this analysis. Products shipped to Vancouver will be repackaged in containers for shipment by sea to China. For the purpose of this study it was assumed that he ZrO 2 would go to Chicago and the REO products will go to China. The REO, niobium and ZrO 2 will be packaged in plastic supersacks while the tantalum will be packaged in 205 l steel drums. All products will be palletized at Pine Point. Rail shipping costs are based on CN quoted rates from Hay River to either Chicago or Vancouver. There is no plan to re-establish the rail line connecting Pine Point and Hay River. Load limits are applicable to the northern section of the rail line in the summer season. In the summer the allowable load per rail car is estimated to be 63.9 t while in winter this rises to 85.7 t for an annual average of 73 t per rail car. The load limits are summarized in Table 18-47.
