Tlou Energy progresses seismic programme and core-hole drilling at Lesedi

Tlou Energy Ltd, the AIM and ASX listed company focussed on delivering power in Botswana and southern Africa through the development of coalbed methane (CBM), has provided an update on the progress of the 2D seismic programme and commencement of core-hole drilling at the company's Lesedi CBM project in Botswana.

Tlou's Managing Director Tony Gilby said: "The seismic survey is progressing very well and the analysis of the data to date has provided sufficient information for the commencement of core-hole drilling at the Lesedi CBM project. The information from the seismic programme along with the core-hole data will be key to the expansion of the company's existing gas reserves and contingent resources, which through provision of increased confidence in the project could add significantly to the inherent value of the company's assets and provide vital data for the commencement of development activities in 2018."


The seismic survey comprises the acquisition of new data over approximately 250 km of the company's CBM acreage. It is being conducted by Velseis Pty Ltd, an Australian seismic acquisition and processing company that provides a fully integrated range of seismic technologies.

The acquisition of data is expected to be completed later this month with final analysis of the data to be prepared thereafter.  The acquisition involves specially designed vehicles that are fitted with a vibrating plate that transmit acoustic signals into the ground at specified locations.  According to Tlou Energy, the quality of the data to date appears to be good, with clear imaging of the coal target section being achieved.

The data is a key input for the company's reserve certifier, SRK Consulting Pty Ltd to gain increased confidence in target coal distribution within Tlou's Lesedi and Mamba permit areas. SRK will use the new seismic data and integrate this with existing aeromagnetic data to provide a clearer picture of the sub-surface geology. The integrated data set will assist in the expansion of gas reserves and contingent resources, and has already identified the first area for core-hole drilling in advance of the first phase of project development.

The company planned a core-hole drilling programme following the acquisition of seismic data from the ongoing seismic survey over the company's Lesedi and Mamba projects.  From the data already acquired, the company, in consultation with SRK, has been able to identify an ideal location in the Lesedi project area for an initial core-hole, with drilling of this core-hole now in progress.

Not only will the drilling of core-holes confirm the coal quality including gas content, it could also provide further useful information for the expansion of the company’s gas reserves and contingent resources. The drilling of core-holes could also provide data over the areas where initial project development is expected to occur.

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 100 MW of CBM power plant.
