RE: COMPLETION OF CONCEPTUAL POWER STATION DESIGN AND SELECTION STUDIES
The Directors of Shumba Coal are pleased to report that the Company has concluded power station design and selection studies which were accompanied by preliminary financial modelling. Clean Coal Technologies have been used in the design to ensure that World Bank emission standards are met by the Power Station.
These studies are a follow on from the power transmission scoping study into transmission solutions describing options available to export power from the Sechaba Energy Project (“SEP”), to be sited on Shumba Coal’s Sechaba thermal coal resource, into the region, which was concluded earlier in the year.
Shumba Coal is in the process of developing a 300MW coal fired power plant (SEP). The power plant will be strategically located in relatively close proximity to the A1 national road and other important infrastructure, such as a railway line and 400kV substation for possible integration. The Company engaged global energy infrastructure engineering leaders, Parsons Brinckerhoff (Power), to provide conceptual studies for the proposed coal fired power plant development addressing site, boiler technology and plant configuration assessment, limestone consumption assessment and conceptual design and description of the power plant based on the preferred boiler technology and configuration.
Based on the study, the power plant is envisaged to be configured as a 2 x 150MW CFB coal fired power plant. The configuration was chosen as the preferred configuration primarily due to suitability of unit size to the Botswana grid and redundancy offered by the configuration.
Furthermore, the power plant is expected to consist of a subcritical non-reheat steam turbine with dry air cooled condenser technology. SOx control will be achieved by in-situ SOx capture by limestone dosing in the boiler furnace. Particulate matter control will be achieved with Electrostatic Precipitators (ESPs). NOx control is achieved inherently in CFB boilers by virtue of their low operating furnace temperatures.
Key SEP Attributes:
• The Sechaba coal resource and good qualities are well suited for power generation.
• The low sulphur Sechaba coal would reduce non-fuel power plant OPEX by 30-40% compared to other alternatives.
• The SEP project economics indicate a competitive and robust project, capable of a low electricity sale tariff.
• The SEP has an Excellent location, adjacent to:
- High-voltage power grid and grid substation
- Developed road infrastructure
- Railway lines
- Communications infrastructure
- Water sources
- Town of Palapye, with large local workforce
• The SEP is capable of supplying power domestically and regionally using existing power transmission infrastructure.
In addition to Parsons Brinckerhoff, CRESCO Project Finance conducted the power station financial modelling and Norconsult which is an interdisciplinary engineering and design consultancy, provided specialist inputs into the studies.
The Directors believe that this is an excellent outcome as it provides further support for the development of the Sechaba Energy Project as a low cost producer of power for consumption in the region.

Shumba Coal is a Botswana Stock Exchange and Stock Exchange of Mauritius listed Exploration Company whose focus is the acquisition and development of highly prospective energy exploration licenses in Botswana. Currently its flagship asset is the Sechaba Project which has approximately 1 billion tonnes of JORC compliant thermal coal resources. Due to its proximity to the A1 highway, railway line and the existence of large resources of ground water and two river basins, the project is potentially well situated for the development of a mine and a power station.
