PRE-FEASIBILITY STUDY OF TIN MINE: A CASE STUDY OF TIN MINE IN THAILAND

Abstract

This research conducted a pre-feasibility study of a cassiterite mining project location at Bankha district, Rachaburi Province, Thailand. The main purposes of this project were (1) resource/reserve estimation, mine design and planning and mine development (2) comparison of ore transportation systems between truck-loader and belt conveyor system and (3) the project financial analysis by using cash model. The resource/reserve estimation and mine design and planning were carried out by using the software “Mincom Minescape 5.7”. The open-pit mining method was chosen and the mineable reserve was estimated at 2,795,468 metric tons. The mining capacity is 700,000 metric tons per year, and the mine life is estimated at 4 years. This resulted in the tin metal production of 2,510 metric tons for the project. The belt conveyor system was used for the main ore transportation system. The result of the project financial analysis showned that the Net Present Value (NPV) was 447,779,678 Baht, the Internal Rate of Return (IRR) was 79% and the Payback Period (PP) was 1 year and 1 month.
