What happened
GMK Jeotermal Araştırma ve Geliştirme Sanayi ve Ticaret A.Ş. is proposing a geothermal exploration campaign involving five boreholes in Balıkesir province. The work would take place within the boundaries of Altıeylül and Kepsut districts.
The proposed sites are in the Çandır, Ovaköy and Aslıhan neighbourhoods of Altıeylül, plus Osmaniye in Kepsut. The scheme is linked to licence ARA.10.00.2023.JEO.2 and access number 3437494. Its reported estimated value is about TRY 99 million.
Each borehole would be drilled to a maximum depth of 750 metres. GMK intends to use drilling to obtain scientific information on geological and tectonic conditions below ground, while characterising the geothermal fluid’s chemical and physical properties.
For readers monitoring geothermal development, the immediate next step is to follow any disclosed drilling results, particularly temperature, flow-rate and other technical measurements. Those findings are the stated basis on which GMK will consider the future-use potential of individual wells.
Why it matters
The proposal concerns resource exploration, not a confirmed geothermal operating project. Its purpose is to establish whether the locations contain a resource with a potential future application, using evidence generated during the drilling programme.
Temperature and flow-rate data will be central to that assessment, alongside other technical results and fluid-characterisation work. The available information does not identify a drilling timetable, a start date or a decision on how any successful well might subsequently be used.
The project also illustrates the early technical work required before a geothermal resource can be evaluated. At this stage, GMK has specified the number of wells, their locations, maximum depth and the types of data it expects to collect, but not the outcome of the exploration.
What to watch
Any future update would need to clarify whether drilling has begun and report the findings from the five sites. Relevant disclosures would include the measured temperature and flow rate, the fluid’s physical and chemical characteristics, and GMK’s resulting view of each well’s future potential.
Until such data are available, the planned activity should be treated as an investigation of geothermal conditions in the licensed area rather than evidence of a developed resource.
