GURVANTES XXXV SOUTH GOBI NATURAL GAS PROJECT
PROJECT
OVERVIEW
The Gurvantes XXXV Project is an exploration project for Coal Seam Gas (‘CSG’) covering approximately 8,400km2 of the South Gobi basin of Mongolia.
Within the Project area multiple very thick (>50m) high quality, bituminous rank, coal seams outcrop at the surface and extend along an east-west strike for approximately 150km. Within the Project area there are six active coal mining operation, twenty six coal mining leases and numerous coal exploration licenses which combined have defined a very large coal resource.
TMK is focused on the responsible development of the Gurvantes XXXV Project and establishing itself as a key supplier of cleaner energy to support Mongolia’s development and address the significant domestic issues around energy security, reliability, and independence.
The Gurvantes XXXV Project is strategically located less than 20 kms from the Chinese border and close to existing gas infrastructure in northern China, presenting a significant advantage to supplying the world’s largest energy market.

TMK Energy continues to achieve major milestones at its flagship Gurvantes XXXV Coal Seam Gas (CSG) Project in Mongolia. In January 2025, gas production commenced from three newly drilled pilot wells, bringing the total to six wells now flaring gas. As water levels are gradually reduced in the new wells (LF-04, LF-05, LF-06) in line with the reservoir management plan, gas breakthrough occurred and total field production more than doubled. These flows are considered “pre-desorption” and are not yet commercial but represent a strong technical validation of the project.
In December 2024, TMK signed a binding Memorandum of Understanding with Jens Energie LLC (JEL) for the offtake of early-stage gas from the pilot wells. JEL will convert the gas into electricity and supply it to local customers, enabling productive use of the initial volumes generated during the pilot phase. This early commercial pathway supports TMK’s long-term vision of building a sustainable energy source for Mongolia.
Earlier, in June 2024, the Gurvantes XXXV Project received a significant regulatory boost with approval of its Detailed Environmental Impact Assessment (DEIA) by Mongolia’s Ministry of Environment and Tourism. This approval allows TMK to conduct extensive drilling and appraisal activities through to 2029. It followed months of consultation and reflects government support for natural gas development as part of Mongolia’s broader energy transition goals.
The project’s foundations were laid in 2022–2023, beginning with TMK’s acquisition of Telmen Energy and the Gurvantes XXXV Project. That year, TMK also achieved a maiden 2C Contingent Resource of 1.2 TCF, the largest CSG resource recorded in Mongolia. This was followed by a 2023 pilot well program which resulted in first gas to surface from LF-01, LF-02 and LF-03. These achievements have collectively de-risked the project and positioned TMK to advance toward commercialisation.
