Tlou Energy Ltd provides an operations update for Lesedi and Mamba CBM projects

Tlou Energy Ltd, an Australian company focussed on developing gas-to-power projects in Botswana and southern Africa through the development of coal bed methane (CBM) natural gas, has provided an update on the progress of its operations at the Lesedi and Mamba CBM projects in Botswana, Africa.

Tlou's Managing Director, Tony Gilby, said: "The lower Morupule coal seam intersected in the two recently completed core-holes appears to be of similar thickness and quality to other core-holes previously drilled by Tlou.  The drilling programme has been very well managed by our operations team and we are delighted to have two core-holes completed. The information from the drilling programme, along with the recently completed seismic survey, is being sent to our independent reserve certifiers with the objective of expanding the existing Gas Reserves and Contingent Resources in early 2018."


Core-hole Drilling

The company planned a core-hole drilling programme to follow the recently completed seismic survey over the company's Lesedi and Mamba projects. In consultation with SRK Consulting (Australasia) Pty Ltd (SRK), Tlou's geological consultants and independent reserve certifiers, the company identified a series of locations using the newly acquired seismic data, for further evaluation by drilling of new core-holes. Two new core-holes have now been completed in the Lesedi project area. This work has been conducted on budget and completed safely within the terms of the company's approved Environmental Impact Statement.


Following coring, desorption samples were taken and placed into desorption baths in the field with readings being taken and sent to Weatherford Laboratories in Brisbane.  Once this analysis is complete, the physical samples will be sent to Weatherford for further analysis.  


Key benefits of the core-hole drilling programme include:

  •   Confirming coal quality, thickness, and gas content in a previously undrilled area of the Lesedi project.
  •   Providing new information to SRK to facilitate the expansion of the company's Gas Reserves and Contingent Resources. An increase in the Gas Reserves and Contingent Resources could significantly increase the company's valuation.
  •    The additional data will be used to determine the optimum location for initial project development as well as high-grading additional areas for further development both within the Lesedi and Mamba project areas.  This provides the company with additional future optionality.  

Initial project development is planned to commence in 2018, subject to the results of the company's application to the Government of Botswana to develop up to 100MW of CBM fuelled power generation.

Results of the desorption testing are expected in 1Q18 and will be taken into account by SRK for expansion of the company's Gas Reserves and Contingent Resources. The company is planning a further core-hole in the Mamba project area and an initial dual lateral development pod for early 2018 with the location to be determined following consultation with SRK.
