Key Points

  • TMK Energy has identified 60m of gassy coals onsite its Mongolian CSG acreage in the Snow Leopard-1 well
  • Drill rig now mobilising 5km east to prepare for spud of Snow Leopard-2
  • TMK Energy confirms high gas content ratios in SL-1 at 96% methane vs 3% average CO2

TMK Energy (ASX:TMK) has completed drilling its Snow Leopard-1 well at the company's Mongolian Gurvantes XXXV Coal Seam Gas (CSG) project in the Mongolian South Gobi Desert region. 

TMK Energy shares the project in a JV structure alongside partner Talon Energy (ASX:TPD)

The partnership intersected 60m of gassy coal in SL-1 and terminated at a total depth of 675 metres. 

Broken down, the company intersected 44.4m in the upper coal seam, and, a further 15.5m in the lower seam on-site. 


Promising results underpin project confidence 

Current desorption rates, the company states, reflect gas contents in the upper range of previous indicated estimates at 7.5m3/t to 12.5m3/t. 

A Drill Stem Test (DST) and Injection Fall Off Testing (IFOT) of targeted coal intervals has been completed and the company now awaits further results from those two tests to provide analytical certainty on natural gas reserves discovered on-site. 

Snow Leopard-1 stands as the maiden well in TMK Energy’s drill run in the Nariin Sukhair area of its Gurvantes project. 

Snow Leopard-2 to be spud next week 

The company will now proceed to drill Snow Leopard-2 using the same drill rig that spud and completed SL-1. Snow Leopard-2 is some 5km to the east of SL-1.

SL-2 is to target the same coal formations as SL-1 and is expected to take four weeks from spud to completion. TMK Energy notes it has picked up valuable experience through drilling SL-1 with regards to drilling the Gobi Desert for CSG targets, and this will optimise operations on-site the SL-2 location. 

The SL-1 drill site is to be “rehabilitated in accordance with local requirements,” the company notes, before the second well in a four-well program is spud next week.
