Continuing to Significantly Extend Dumbwa System
Drilling at Dumbwa has now established strike over 3.6 kilometres
Vancouver, British Columbia, January 29th, 2026 – Midnight Sun Mining Corp.
(TSXV: MMA / OTCQX: MDNGF) (“Midnight Sun” or the “Company”) is pleased to report
assay results from 28 holes, totalling 5,247.30 metres (“m”), from its 100% owned
Dumbwa Target, located in Solwezi, Zambia . Ongoing drilling continues to
significantly extend the mineralized system at Dumbwa along strike.
Highlights of Drilling include:
• DBW-25-021 intercepted 0.89% Cu over 25m. 4 separate mineralized zones were
intercepted within the hole.
• DBW-25-030 intercepted 0.46% Cu over 50m, including 1.36% Cu over 6m.
• DBW-25-027 intercepted 0.48% Cu over 21.85m.
Midnight Sun’s COO, Kevin Bonel, states “ Similar to the nearby Lumwana Mine,
delineating basement- hosted copper systems like Dumbwa requires defining
continuous, shallow mineralization along extensive strike at surface, and these latest
intercepts continue to do exactly that. Each hit strengthens our confidence in the
Dumbwa system and further validates our thesis. Our strategy of methodically
delineating Dumbwa in 100 to 200 metre increments along strike has proven to be
the right strategy to rapidly revea l the t rue scale of this copper system. We are
advancing quickly, hitting consistent copper mineralization that mirrors what my
team encountered as we expanded Lumwana. With drilled strike length now
exceeding 3.6 kilometres with exceptional continuity, we are efficiently tracking the
system and delineating it with precision. As the strike continues to grow, each step-
out makes Dumbwa larger, stronger, and increasingly compelling.”

Dumbwa Drill Program Update
The drilling at Dumbwa has now demonstrated 3.6 kilometres of north-south
mineralized strike. To date, 122 holes have been completed with 5 holes ongoing and
a further 140 holes called for in the immediate plan to test the mineraliz ed corridor
over the next 3 kilometres of strike. This represents approximately 25,000 metres of
planned drilling.
Samples from an additional 64 drill holes have been submitted for assay, with the
remaining samples currently being cut and prepared.
Quality Control/Quality Assurance
Drilling was conducted using a conventional diamond drilling rig and drill core was
captured for the entirety of each hole and placed into plastic core trays. All drill holes
were cored in PQ until stable ground was achieved and then reduced to HQ size for
the remainder of each hole. Sampling was based on visible copper mineralization
and sample intervals honoured any important lithological boundaries. Core was then
cut in house using a diamond saw and the right half of core was placed into a 200
micron plastic bag, assigned a unique sample number, and recorded into GeoSpark
logging system. Samples always remained under the supervision of Midnight Sun
staff to maintain chain of custody. All samples were then delivered to SGS Labs
located in Kalulushi, Zambia , a fully accredited laboratory. Once received, the
samples were sorted, dried, crushed, and pulverized (SGS code PRP90) followed
by four-acid digest with ICP-OES finish (SGS Code ICP42S). Copper range of detection
is 0.01-10%. Midnight Sun follows an in- house QA/QC program that consisted of a
random insertion every 10 th sample of either a coarse blank, fine blank, coarse
duplicate, fine duplicate, or Certified Reference Material (standards).

About Midnight Sun
Midnight Sun is rapidly advancing the Solwezi Copper Project, with a focus on our
flagship Dumbwa Target. The Project is located near the town of Solwezi in the heart
of the Zambia –Congo Copperbelt, the world’s second -largest copper -producing
region. This prolific mining district is renowned for hosting multiple major copper
deposits, and benefits from excellent infrastructure, an established mining
workforce, and a long history of successful production.
The Solwezi Copper Project is surrounded by producing copper mines, including the
geologically similar Lumwana Mine just west of our project and First Quantum ’s
Kansanshi Mine, Africa’s largest copper mining complex, approximately 6 kilometres
east of the company’s recently announced Kazhiba Oxide Resource . This highly
favourable location highlights the district- scale potential of Midnight Sun’s land
package.
The Dumbwa Target hosts a robust 20 -kilometre copper -in-soil anomaly, and
ongoing drilling has demonstrated strong geological similarities to the nearby
Lumwana deposit, underscoring its potential to host a significant copper system.
Led by an experienced geological team with a proven track record of major
discoveries in the Zambia –Congo Copperbelt and globally, Midnight Sun’s goal is to
delineate Zambia’s next generational copper deposit.
