Mining Prefeasibility Study for Morupule Power Station, Botswana
With energy demands rising sharply worldwide, Morupule Colliery Limited (MCL) in Botswana, a division of Debswana, is planning to increase its coal production to satisfy the proposed expansion of its Morupule power station, as well as to meet the needs of the local and cross-border markets.
In May this year, SRK began a mining prefeasibility study to address this proposed expansion. The study will take place over a three-to-four month period. This is the latest in a number of projects SRK has undertaken involving Morupule.
In 2005, MCL asked SRK to take existing coal data for the Kgaswe Prospecting Lease, located in the Morupule Coalfield, and examine the geology and coal quality. The main target is the Morupule seam, which is currently mined at MCL.
In early 2006, SRK assisted in determining the quantity of the coal resource available at MCL to support the proposed expansion of the Morupule power station. To allow a greater understanding of the coal deposit, the structure and the extent of the coal resource, the team created a 3D computer model of the deposit in Minescape – a software tool particularly effective in modelling coal deposits.
The 3D model was also used to determine an exploration program. It allowed SRK to recommend the siting of 3 additional boreholes, which allowed for 50% of the Morupule seam resource at MCL to be classified as a Measured Coal Resource.
To date, drilling has been completed with SRK responsible for the supervision, logging and coal sampling. Currently, the analysed results are being built into the 3D computer model. Re-estimation of the resource is being carried out to meet an internationally recognised mineral reporting code.
This particular phase of the project is almost complete.
