(KMI KMI Kerrigan Media International, Inc. KMI Koninklijk Meteorologisch Instituut KMI Key Management Infrastructure KMI Knowledge Management Institute (George Washington University) KMI Keep Me Informed ), a joint venture between Echo Bay Mines Ltd. (75%), the operator, and TVI Pacific Inc. (25%). This initial study incorporates capital and operating costs estimated to +/- 20%.

These resources at Kingking contain 2.99 billion pounds of copper and 6.6 million ounces of gold, which is a significant increase from the 1993 resource estimate by Benguet Corp. (NYSE NYSE See: New York Stock Exchange : BE) of 2.11 billion pounds of copper and 3.8 million ounces of gold.A mine based on these resources would produce 4.5 million ounces of gold and 2.3 billion pounds of copper. Operating costs for this mine have been estimated at $0.72/tonne of material for mining, $2.80/tonne to mill sulfide ore and $3.99/tonne to mill oxide ore. These results translate into operating costs of $0.69/lb of copper and $257/ounce of gold, including transportation and treatment and refining costs. Project Economics Two cases have been investigated in the initial feasibility study, one incorporating Land Based Tailings Disposal (LBTD) and the second case using Submarine Tailings Disposal (STD (Subscriber Trunk Dialing) Long distance dialing outside of the U.S. that does not require operator intervention. STD prefix codes are required and billing is based on call units, which are a fixed amount of money in the currency of that country. ). The LBTD case initial capital cost is estimated at $642 million and establishes project break even costs (un-discounted) of $0.87 per pound of copper and $340 per ounce of gold on a co-product basis (costs shared proportional to revenue). The estimated initial capital cost for the STD case is $607 million and establishes project break-even costs of $0.84 per pound of copper and $324 per ounce of gold. Submarine tailings disposal is considered the more attractive technical approach. Project Location and Property Claim Structure The Kingking project is located on the island of Mindanao, Philippines, approximately 20 kilometres by road northeast of the town of Pantukan in the province of Davao del Norte Davao del Norte, and once known simply as Davao, is a province of the Philippines located in the Davao Region in Mindanao. Its capital is Tagum City. It borders the province of Agusan del Sur to the north, Bukidnon to the west, Compostela Valley to the east, and the city of . The climate is tropical; normal precipitation is 2100 millimeters per year with temperatures ranging from 18 to 35 degrees Celsius. A Mineral Production Sharing Agreement Production sharing agreements (PSAs) are used primarily to determine the share a private company will receive of the natural resources (usually oil) extracted from a particular country. grants to Benguet Corp. (Benguet) and National Development Corporation (Nadecor) the exclusive right to explore, develop, and mine minerals within the area of the Kingking deposit. Kingking Mines, Inc. has negotiated agreements with Benguet and Nadecor to develop this deposit. Project Plan The porphyry deposit contains both sulfide and oxide copper/gold ores. Mining of the deposit would be by conventional open pit methods, using electric shovels, diesel-powered drills and trucks. The life of the mine would be 16 years at a nominal milling rate of 70,000 tonnes/day and an average stripping ratio of 1.12:1, and an average of approximately 70,000 tonnes of copper in concentrate, and 296,000 ounces of gold, would be produced annually from this operation. In the first five years, production would average approximately 87,000 tonnes of copper in concentrate and 400,000 ounces of gold. The two ore types require separate processes for optimum metal recovery. The proposed design employs standard comminution comminution (k leach, iron precipitation and low pH flotation for the copper precipitate (LPF LPF - League for Programming Freedom ). Project Optimization The work completed to date is preliminary and further work is required to optimize the project and enhance the overall project economics. The areas where this potential can be realized are listed below: The potential exists for expansion of the deposit on strike and for the area in general. There is the potential for an increase in the metallurgical recovery of copper. There is the potential to utilize the Solvent Extraction Solvent extraction A technique, also called liquid extraction, for separating the components of a liquid solution. This technique depends upon the selective dissolving of one or more constituents of the solution into a suitable immiscible liquid solvent. Electrowinning process thereby producing cathode copper which may improve project economics. Alternate infrastructure layouts may reduce capital costs. Alternate power supply options may reduce operating costs. The project would generate significant cash flows during strong metal prices. Addition of a molybdenum molybdenum (məlĭb`dənəm) [Gr.,=leadlike], metallic chemical element; symbol Mo; at. no. 42; at. wt. 95.94; m.p. about 2,617°C;; b.p. about 4,612°C;; sp. gr. 10.22 at 20°C;; valence +2, +3, +4, +5, or +6. circuit and recovering molybdenum from some of the ore may be worthwhile. The optimization of the project will be completed by the joint venture partner team over the next few months. TVI believes that the optimization process will result in a project with attractive economics at reasonably expected metal prices. It is important to note that there is potential for defining new high grade gold and/or copper zones with further drilling. Additionally, the exploration potential of the remainder of the joint venture property outside of the Kingking deposit itself is largely untested. CONTACT: TVI Pacific Inc.
