9 Oct 2023drilling result▲ GoodMajor

Terra-area well BHN23_002C intersected about 45m of net coal with moderate to high gas content, in the same formation as Nariin Sukhait about 100km west, so four more wells are added. The two earlier wells found thin coal with low gas. Lucky Fox-3 had pump problems from coal fines.

13 July 2023drilling progress report● Neutral

Pumps and drive heads are installed and all surface facilities are complete at the three pilot wells; the production test is expected to start within a week. Dewatering is now expected to take two to three months before initial gas breakthrough.

28 June 2023drilling progress report● Neutral

Surface facilities for the three pilot wells are over 80% complete, with pump installation due early July and the six-month production test now scheduled for mid-July. Sustained gas is not expected until several months after pumps start; early water flow is expected.

9 Nov 2022resource reserve update▲ GoodMajor

NSAI certified a maiden Gurvantes contingent resource of 398 Bcf (1C), 1,214 Bcf (2C) and 2,361 Bcf (3C). The 1C and 2C are all in the upper seam; the lower seam has only 3C (417 Bcf) because permeability data is lacking.
