Midnight Sun Terminates Letter of Intent and Term Sheet to Acquire Remaining 40% of Partnership

VANCOUVER, October 1, 2018 - Midnight Sun Mining Corp. (the ''Company'' or ''Midnight Sun'') (TSX-V: MMA) announces the termination of the previously announced letter of intent and term sheet with Kam Chuen Resource Holdings Inc. (''Kam Chuen'') to acquire the remaining 40% interest in Zambian High Light Mining Investment Limited (See news release dated February 20, 2018 for more details).

ZHLMIL holds the two large scale exploration licenses collectively known as the Solwezi Licenses. Midnight Sun and Kam Chuen will continue to operate as partners in ZHLMIL with Midnight Sun holding a 60% interest and Kam Chuen holding a 40% interest as contemplated in the original property option agreement dated July 30, 2013.

The Company's President and Chief Executive Officer, Brett Richards stated: ''The acquisition of the remaining 40% of Zambian High Light Mining Investment Limited no longer makes sense in the context of the current market, and we are happy to move forward with Kam Chuen as partners on the Solwezi Licences.''
