Midnight Sun and KoBold Metals Join Forces

on the Dumbwa Target in Zambia

KoBold Metals, an AI driven battery metal exploration and mining company, can spend USD$15

million in exploration and make cash payments totaling USD$500,000 over 4.5 years to earn a

75% interest in the Dumbwa portion of Midnight Sun’s Solwezi Project.

Vancouver, British Columbia, February 20 , 202 4 – Midnight Sun Mining Corp. (the

“Company” or “Midnight Sun”) (TSX -V: MMA / OTCQB: MDNGF) is pleased to announce the

Company has signed an earn -in agreement (the “Earn -In Agreement”) with KoBold Metals

Company (“KoBold”) , through their respective Zambian subsidiaries, to explore the

Dumbwa Target (“Dumbwa Target” or “Dumbwa ”), located on the Company’s Solwezi

Project in Zambia.

KoBold Metals Company is a US -based, privately held, battery metal exploration and

mining company that combines geoscience, data science, machine learning, and artificial

intelligence to search for the critical minerals needed for the clean energy transition .

KoBold is backed by technology investors including Breakthrough Energy Ventures

(initiated by Bill Gates) and Silicon Valley venture capital firm Andreessen Horowitz, as well

as institutional investors such as T. Rowe Price and Canadian Pension Plan Inve stment

Board.

The Earn -In Agreement allows KoBold to earn a 75% interest in Dumbwa by incurring

USD$15 million in exploration expenditures and making cumulative cash payments to

Midnight Sun of USD$500,000 over 4.5 years.

Midnight Sun President & CEO Al Fabbro states: “KoBold has assembled one of the top

global sediment -hosted copper teams – including Dr. David Broughton – and I cannot

overstate how pleased we are to have them at the helm on Dumbwa. Their bench strength

speaks to the quality of this outstanding tier -one exploration target and the seriousness of

their approach. As evidenced by the impressive roster of keystone investors in KoBold, they

are on track to become new industry leaders using incredibly sophisticated proprietary

technology t o fast -track the discovery of critical minerals . We look forward to KoBold

applying their groundbreaking exploration approach to the Dumbwa Target and moving

this important Zambian copper asset toward development together, which we view as

perfectly timed to coincide with an upcoming phase of unprecedented global copper

demand.”

KoBold Metals Africa Chief Executive Officer, Mfikeyi Makayi, states: “KoBold is looking

forward to exploring the Dumbwa Target alongside Midnight Sun as we have long been

interested in the Solwezi Dome. The Dumbwa Target hosts intriguing copper -in-soil

anomalies and a structural setting comparable to other major deposits in the region. The

KoBold sediment -hosted copper team has decades of experience working in the African

Copperbelt, which we will combine with our library of analytical tools and proprietary

technology to aggressively explore at Dumbwa. We look forward to working with Midnight

Sun and drilling at Dumbwa in 2024.”

The Dumbwa exploration target is located in the heart of the Zambia -Congo Copperbelt,

and is one of four key prospects that comprise Midnight Sun’s 506 2 kilometre Solwezi

Project (see Figure 1) . Dumbwa is located within one of three exploration licenses held by

the Company; the Company anticipates continuing exploration on its other licenses as well

as the portions of the license within which Dumbwa is located that are not subject to the

earn-in. The Dumbwa Target area included in the KoBold agreement is 1082 kilometres.

KoBold plans to initiate a drill campaign in 2024 to begin systematic exploration of

structural targets at Dumbwa.

The remaining 398 2 kilometres of property that make up the Solwezi Project will remain

with Midnight Sun, and the Company intends to continue exploration on the other key

targets outside of the area subject to the KoBold Earn-In Agreement.

● Year 3 Anniversary of Agreement Date - USD $100,000

● Year 4 Anniversary of Agreement Date - USD $100,000

Commencement of the earn -in is subject to a number of conditions, including the re -

assignment of the license within which the Dumbwa Target is located to the Company’s

subsidiary. The Earn-In Agreement provides that if the conditions are not satisfied by June

30, 2024 (unless otherwise agreed to by the parties), the Earn -In Agreement will terminate.

KoBold has the right to extend the outside date by up to six months, in KoBold’s sole

discretion.

Formation of Joint Venture Company

Upon completion of the obligations under the Earn -In Agreement by KoBold , the parties

will form a separate company (the “JV Co”), to be held initially by KoBold and the Company

(or their Zambian subsidiaries) as to 75% and 25% respectively. The parties to the JV Co will

be subject to the terms of a Shareholder’s Agreement, a copy of which is included as an

appendix to the Earn -In Agreement. The parties have agreed that the Dumbwa Target will

be separated from the Company’s existing license into a new license, and assigned to JV Co.

The agreed form of Shareholder’s Agreement includes the following material terms:

• JV Co be governed by a Board of Directors, init ially consisting of two directors

nominated by KoBold, and one director nominated by the Company

• JV Co will propose work programs. Shareholders will have the obligation to fund

their proportionate interest, or face dilution as a result of a failure to participate

• A party diluted to less than a 10% interest will have their interest converted to a 1%

Net Smelter Royalty capped at USD$40 million

• Authority of the Board will be subject to certain matters reserved to Shareholders

• The Company will have a right to participate pro rata in future issuances of shares of

the JV Co

• The Company’s shareholding interest will be subject to drag along rights in favour of

the majority shareholder ( KoBold), and the Company will have the benefit of tag

along rights in the event of a sale by KoBold

• The JV Co will have the ability to cancel shares held by a party in the event that the

party is or becomes controlled by a sanctioned entity, and will have the right to

repurchase the shares for fair market value in certain other circumstances

Dumbwa Target Highlights

● The Dumbwa Target features a continuous high -grade copper -in-soil anomaly,

which extends for over 20 km along strike and +1 km in width, with peak values of

up to 0.73% copper.

● The Dumbwa Target features multiple stacked mineralized horizons, which are

believed to be analogous to Barrick’s Lumwana Mine, located ~40 kilometres to the

west of the Solwezi Project.

● Exploration work to date, which includes geochemical analysis and geophysics,

indicate that systematic drilling guided by structural controls is the next step toward

establishing continuity, size, and scale of an underlying system.

The Earn-In Agreement remains subject to regulatory approval as well as customary

conditions and contains representations, warranties, covenants and indemnities as are

typical for agreements of this nature.
