Midnight Sun Mining Provides Corporate Update

Solwezi Licenses Option Agreement Vesting

Midnight Sun has satisfied all of its obligations under the Option Agreement with Kam Chuen Resource Holdings Ltd. ("Kam Chuen") and has earned a 60% interest in the Solwezi Group of Exploration Licences (the "Licences") (See November 29, 2013 news release titled "Midnight Sun Signs Definitive Option Agreement for Exploration Permits in Zambia").

The Licences consist of two individual exploration licences, 21509-HQ-LEL (formerly 14039-HQ-LPL) and 12124-HQ-LEL (as shown below in Illustration 1.0 - Solwezi Group of Licences), covering over 506 km² of surface area. The Licences are located in northern Zambia, adjacent to Africa's largest copper producer, the Kansanshi Mine, on the prolific Zambia-Congo Copper Belt. Having satisfied all obligations under the option agreement, the Company is now in the process of formalising a shareholders and governance agreement with Kam Chuen to govern the further exploration and operation of the Licenses as a joint venture.

2018 Exploration Program

The Company is planning a comprehensive exploration program for 2018, beginning in April, immediately after the rainy season in northern Zambia.

Initially, Midnight Sun will conduct an airborne geophysical survey [Heli-borne Versatile Time Domain Electromagnetic ("VTEM")] over the three main targets: Mitu, 22 Zone and Dumbwa (north and central), and the additional prospective targets of Khaziba and Kifubwe.

Once completed, the Company will prepare a comparative interpretation utilizing the new data from the VTEM survey and the known drill data from its 2016 and 2017 drilling campaign to determine primary and secondary drill targets on the 3 main mineralized areas, with a principle focus on Mitu.

The Company's President and Chief Executive Officer, Brett Richards stated: "This year, Midnight Sun is going to increase capacity in almost every area of its business. We are going to increase our presence and activities on the ground in Zambia and will be ramping up with multiple geological teams to quickly and efficiently understand the prospective targets than have been located and proven from our campaign last year. We intend to initiate the forthcoming season starting with an airborne geophysical program over the licences, followed by a ground geo-physical program and an aggressive drilling campaign on each of the targets identified: Mitu, 22 Zone and Dumbwa (North and Central)."

2016 and 2017 Exploration Work

The focus of the 2016 and 2017 exploration programs and drill campaigns was to expand and further define the extent of the previously announced ore-shale type copper-cobalt discovery at the Mitu area of the Solwezi Licences. These programs included drill hole MDD-17-15 which stepped out 3.72 kilometres ("km") southeast from discovery hole MDD-16-01, and reported 3.44% copper, 0.067% cobalt, 0.058% nickel and 331 parts per billion gold (4.23% copper equivalent) over 11.6 meters (see news releases dated January 12, 2017; February 10, 2017; May 3, 2017; and July 4, 2017).

A secondary focus of the 2016 and 2017 joint campaign was to understand the mineralization and lithology of the two other regional targets on the Licenses, identified as 22 Zone and Dumbwa (north and central).
