MIDNIGHT SUN CONFIRMS HIGH GRADE DRILL INTERCEPTS AT MITU Copper mineralisation style and grade similar to Sentinel Mine
MIDNIGHT SUN CONFIRMS HIGH GRADE DRILL INTERCEPTS AT MITU
Copper mineralisation style and grade similar to Sentinel Mine
Vancouver, British Columbia, July 25, 2023 – Midnight Sun Mining Corp. (the “Company” or “Midnight
Sun”) (TSX -V: MMA / OTCQB: MDNGF ) is pleased to provide the remaining drill results from holes
MTDD047 and MTDD048, and a summary of results from the 2022 drilling campaign on the Mitu Trend,
one of four key p rospects which comprise the Company’s Solwezi Project in Zambia. Initial laboratory
results were received shortly after the conclusion of d rilling in 2022, however the Company chose to re-
assay select drill core in order to confirm laboratory accuracy. SGS Inspection Services Kalulushi, has now
completed all assays and the Company is pleased to report that initial results were confirmed, and
significant mineralisation was encountered. Copper mineralisation intercepted at Mitu is associated with
cobalt, nickel, and anomalous gold. This suite of metals is comparable in mineralization style and grade
to those at First Quantum’s Sentinel Mine, located approximately 120 kilometres west of Midnight Sun’s
Solwezi Project.
2022 Mitu Drill Highlights Include:
• MTDD044: 11.50m @ 1.41% copper, 0.11% cobalt, and 0.03% nickel
o Incl. 4.15m @ 1.29% copper, 0.13% cobalt, and 0.09% nickel; and
o Incl. 5.80m @ 1.86% copper, 0.07% cobalt, and 0.02% nickel
• MTDD045: 7.30m @ 0.58% copper, 0.02% cobalt, and 0.02% nickel
• MTDD047: 26.10m @ 0.32% copper, 0.07% cobalt, and 0.05% nickel
• MTDD048: 22.25m @ 0.39% copper, 0.01% cobalt, and 0.01% nickel
Al Fabbro, Midnight Sun ’s President & CEO, stated: “We are very pleased to see that these final results
from Mitu are consistent with earlier drilling. Though delays are never ideal, confirming our initial
results was a prudent step toward developing a sound technical model and establishing our future plans
for this key component of our Solwezi Project. Our 2022 exploration program has accomplished
precisely what we had hoped for, which is proof of concept. This new work has revealed more insight
into the mineralisation at Mitu, and most exciting for our team is the revelation that the geology at Mitu
is consistent with that of First Quantum’s Sentinel Mine, located a short distance to the west. We have
long believed that there could be multiple large geological systems on our 50 6 square kilometre
property, and this not only establishes an analog for Mitu, but strengthens our belief that more than
one generational copper deposit may exist on our property.”
Midnight Sun completed 17 diamond -drill-holes totaling 3,559 metres (“m”) on the Solwezi Project
during the 2022 field season , consisting of 7 holes at the Mitu Trend target area and 10 holes at the
Crunch Zone target area. Initial results were announced on November 7 , 2022 . The 2022 drilling
program resulted from a review of available date and culminated in a set of drill targets that included a
‘new look ’ at existing target areas as well as newly defined targets interpreted from high -resolution
geophysical data over the project area.

Notes:
• Reported intervals are the downhole widths. More structural and orientation data is required to determine true
widths.
• Reported intervals are calculated for zones assaying > 0.1% copper or 0.01% cobalt and containing less than 2 meters
of internal waste.
• Copper equivalent values are estimated using current metal prices of $3.75/lb copper, $ 15/lb cobalt, and $ 9.25/lb
nickel. Gold has not been included in the equivalent calculation.
• Copper equivalent values are presented for ease of interval comparison only. Metallurgical recovery factors are
assumed to be 100% although the recovery factors for various metals may vary significantly.

Quality Control/Quality Assurance
Samples obtained during the diamond drilling were transported directly to SGS Inspection Services in
Kalulushi, Zambia by Midnight Sun personnel for sample preparation. There the samples were sorted,
dried, crushed, and pulped before final chemical analysis using ICP 42S method which encompasses a 3
or 4 acid digest followed by an AAS multi-element scan. All samples returning >10,000 ppm Cu were
automatically re-assayed for higher level concentrations by SGS, which is a fully accredited laboratory.
Standards and blanks were inserted regularly in the sample stream and checks were done for Cu. A
subset of pulps from MTDD044 and MTDD045 were selected and airfreight to SGS South Africa for gold
analysis by fire assay.
