Midnight Sun Announces Significant New Targets at Kazhiba

Recently completed surveys identify significant sulphide and oxide copper

targets with drill testing to commence in Q2 2025

Vancouver, British Columbia, February 27th, 202 5 - Midnight Sun Mining Corp. (TSXV:

MMA / OTC: MDNGF) (“Midnight Sun” or the “Company”) is pleased to announce that results

of the recently completed 2024 geochemical and geophysical exploration programs have

defined significant new sulphide and oxide targets on Kazhiba. Exploration drilling is set to

commence in early Q2 and is designed to concurrently test these new sulphide and oxide

targets.

Partial Ionic L each geochemistry has identified a strong copper anomaly extending over

four kilometres that aligns perfectly with high chargeability, low resistivity stratigraphy as

exposed by the i nduced polarization (“IP”) survey. This new sulphide copper anomaly

directly overlays a subtle, historic geochemical anomaly, and is situated in geology

consistent with the majority of deposits within the Zambian Copperbelt. In addition to this

new sulphide target, the partial leach geochemistry has also revealed three new copper

anomalies that share a very similar geochemical signature to the known Kazhiba oxide

copper occurrence, which was drilled in late 2024 (see news release dated January 29, 2025).

Midnight Sun’s COO, Kevin Bonel, stated: “We are incredibly pleased with the results and

brand-new targets generated by the Partial Ionic Leach sampling and IP survey. Taking the

coincidence of a well-defined copper anomaly, in the ‘right geology’ with an underlying high

chargeability, low resistivity, IP reactive unit, the geological team’s confidence is high that

the unexposed unit is a copper mineralised stratigraphic unit. Not on ly do we now have a

potential sulphide source for the high -grade oxide copper mineralization at Kazhiba, but

we also have additional targets for more oxide copper mineralization to explore and

hopefully add to our Cooperative Explorative Plan with First Quantum. The results simply

could not have been better at this stage of exploration on our Kazhiba Target.”

The New Kazhiba Targets Detailed:

In late 2024, Partial Ionic Leach sampling and an IP Survey were conducted on the

Company’s Kazhiba Target as part of the 2024 Exploration Program. Both produced positive

results and generated several significant targets. The Partial Ionic Leach sampling produced

a new copper-in-soil anomaly, which extends for approximately 4 kilometres on strike. The

geology of this new target is interpreted as Katangan sediments onlapping onto older

basement lithologies of the Kazh iba Dome, itself interpreted from geophysics as an

unexposed, shallow, basement inlier within the Kazh iba inlier. This is the classic Zambian

Copperbelt setting.

Concurrent with the partial leach geochemical sampling program, an IP survey over

“Kazhiba Target 2” was undertaken, designed to test for an unexposed sulphide

mineralised stratigraphic unit overlying the interpreted Kaz hiba Dome. This target is

proposed as a possible source of the transported oxide-copper blanket recently tested by

exploration drilling.

The IP Survey has indicated a chargeable unit in the stratigraphy that is strongly correlated

to the overlying Partial Ionic Leach copper anomaly. In addition, IP is indicating that the unit

has very low resistivity, which is a strongly favourable characteristic.

The combination of a subtle historic geochemical anomaly, coinciding with a brand -new

copper-in-soil anomaly, all of which correlate with a high chargeability, low resistivity, IP

reactive unit in favourable geology, has produced a very strong target for the discovery of a

new copper mineralised stratigraphic unit.

Exploration drilling is now planned for early Q2, designed to test Kazhiba Target 2 for the

discovery of a new copper sulphide minerali sed stratigraphic unit within the Kaz hiba

licence. Drilling is also planned to extend the initial oxide copper footprint delineated in

recent drilling (see news release dated January 29, 2025) as well as test three new partial

leach copper anomalies for additional oxide occurrences.

About Midnight Sun

Midnight Sun is focused on exploring our flagship Solwezi Project, located in Zambia.

Situated in the heart of the Zambia -Congo Copperbelt, the second largest copper

producing region in the world, our property is vast and highly prospective. Our Solwezi

Project is surrounded by world -class producing copper mines, including Africa’s largest

copper mining complex right next door, First Quantum’s Kansanshi Mine. Led by an

experienced geological team with multiple discoveries and mines around the world to their

credit, Midnight Sun goal is to find and develop Zambia’s next generational copper deposit.
