Toronto – September 17, 2026 -- Hemlo Mining Corp. (TSX: HMMC) (OTCQX: HMMCF) confirmed a temporary electrical outage on September 4, 2026, at an underground substation feeding the Alimak production area on the 9765 level of its flagship Hemlo Gold Mine in northwestern Ontario, with no injuries reported and all underground personnel safely evacuated.
A replacement substation ordered under a critical spare parts audit is due in December 2026 at an estimated cost of US$250,000
The company had pre-ordered the replacement unit before the failure occurred, a move that now shortens the repair timeline. In the interim, technical teams have installed a temporary electrical bypass that restores power to the affected zone at reduced capacity, allowing some mining to continue while development and exploration work remains constrained.
