Noble Helium (ASX:NHE) temporarily postponed its western margin shallow drilling program in Tanzania until February 2025 due to weather events and delay in obtaining tax clearance from the Tanzanian Revenue Authority, according to a Tuesday filing with the Australian bourse.

The clearance will allow contracted drillers, BoreXpert, to complete customs procedures and import the rig into Tanzania, the filing said.

Shares fell nearly 16% in afternoon trade Tuesday and earlier hit an all-time low.
