The Mabini, Batangas Geothermal Service Contract was awarded to the Company on July 10, 2008. The contract area is approximately 32.5 square kilometers and covers the Calumpan Peninsula. The contract period for exploration is 5 years, and was extended up to 2015, subdivided in 3 Phases. Sub Phase 1 (Years 1 and 2) and sub phase 2 (Year 3) minimum work commitments include geological, geophysical and geochemical works that are designed to identify a drilling location and assess the geothermal potential of the contract area. The Company has the option to drill a well or return the Service Contract to the Department of Energy in case there is no technical justification to drill a well.
The Company has secured the commitments of the Local Government Units which indicated support to the project. The Certificate of Non Coverage was issued by the Environmental Management Bureau on March 25, 2009 and the Certificate of Non Overlap from the National Commission on Indigenous People was issued on April 15, 2009.
The Company has conducted the first stage of the exploration program consisting of geophysical and geological surveys covering 3,481 hectares in the Calumpan Peninsula, Mabini, Batangas. A Controlled Source Magneto-Telluric Survey covering the area had been conducted and completed on March 8, 2010.The data obtained from the survey had been processed by a Japanese consultant, with the objective of establishing the geothermal resource and the exploration drilling site in the area.
The Company has completed due diligence studies and preliminary technical data collection, collation and re-evaluation as part of its commitment under Sub Phase 1 (Years 1 and 2) of the work program committed with the DOE. Initial assessments disclosed that the area has a good potential for a 20-megawatts capacity and could be developed within a 2-year period considering the existence of adequate infrastructure, adjacency to transmission lines and a strong power demand in the area.
For this service contract, the work program is currently on Sub-Phase 3 which involves the drilling of one (1) exploratory well by 2015. Estimated costs for this work program is Php166 Million. Trans-Asia Energy Corporation has committed to a 10% participating interest in this project, with an option to increase up to 40% participating interest, subject to the results of a gravity survey which it will undertake. Discussions are on-going with prospective drilling contractors and project management service providers.
