Operations update for Lesedi and Mamba CBM projects

Tlou Energy Ltd, the AIM and ASX-listed company focussed on delivering power in Botswana and southern Africa through the development of coal bed methane (CBM), has reported on the progress of its 2D seismic programme and core-hole drilling operations at its Lesedi and Mamba CBM projects in Botswana. 

Tlou's Managing Director, Tony Gilby, said: "This new seismic data appears to be excellent quality and has the potential to guide us towards the delineation of further gas reserves and contingent resources and enable us to determine the optimum location for the first phase development wells planned for 2018. Velseis, our seismic consultant, is processing the remaining lines and the final data set will be supplied to SRK, Tlou's geological consultants, for interpretation and we will provide further updates regarding this in 1Q18." 


Seismic Survey

The seismic survey covered 250 km of the Lesedi and Mamba projects including part of the Mining Licence area and was conducted by Velseis Pty Ltd, an experienced Australian seismic acquisition and processing company that provides a fully integrated range of seismic services. 


The new seismic data is of excellent quality and will serve to provide a more accurate picture of the subsurface target coal horizon.   

SRK Consulting (Australasia) Pty Ltd (SRK) - Tlou's geological consultants and independent reserve certifiers - will carry out the seismic interpretation.  This will include integration of the new seismic data with existing well and aeromagnetic data sets.  A report will then follow which is anticipated in early 1Q18. 



Core-hole operations

Drilling of core-holes is well advanced in the field with three new core-holes to be completed using two drilling rigs. Drilling is steadily progressing with the first core-hole already complete and a number of coal samples taken from the target coal seam and sent for gas analysis. 

The core-holes are designed to provide additional data along with the seismic survey, to assist with enhancing the company's gas reserve and contingent resource certification. The core-hole information will also be used to plan the first phase of development drilling planned for 2018.
