Midnight Sun Drills New High Grade Mineralization at Mitu
MIDNIGHT SUN DRILLS NEW HIGH GRADE MINERALIZATION AT MITU
Vancouver, British Columbia, November 7, 202 2 – Midnight Sun Mining Corp. (the “Company” or
“Midnight Sun”) (TSX -V: MMA / OTCQB: MDNGF) is pleased to release the initial results from drilling
conducted on its Solwezi Licences during 2022. The Solwezi Licences are located immediately southwest
of First Quantum’s Kansanshi Copper Mine, the largest copper mining complex in Zambia.
Exploration Highlights
• 12 diamond drill holes, totalling 2,639 metres (“m”), completed to date during 2022
• A new mineralization style intercepted, which is comparable to that at the Kansanshi Mine
• Assay results received for five drill holes. Results include:
o 4.15m @ 2.28% Cu eq (1.29% Cu & 0.13% Co & 0.09% Ni) from 113.5m
o 5.80m @ 2.41% Cu eq (1.86% Cu & 0.07% Co & 0.02% Ni) from 119.2m
o 7.3m @ 0.79% Cu eq (0.58% Cu and 0.02% Co & 0.02% Ni) from 149.0m
Overview
Midnight Sun’s 2022 exploration program was designed to validate and confirm new structural control
models for upgraded stratabound copper mineralization in different areas of known mineralization on
the Solwezi Licen ces. The new structural control models were developed in-house following a review
and re-interpretation of past exploration work and new high-resolution geophysical data over the
project area.
During the 2022 Solwezi field season, Midnight Sun has completed 12 drill holes totaling 2,639 metres of
core with two additional drill holes currently in progress. Drilling has been on the Mitu Trend and on the
Crunch Zone P rospect. The Company intends to continue field wo rk as long as weather conditions
permit. For the balance of the 2022 field season , the Company’s work will focus on gaining a better
understanding of the newly identified Kansanshi-style mineralization on the Mitu Trend.
Al Fabbro, President and CEO of Midnight Sun, stated, “The start of our 2022 program has accomplished
precisely what we hoped for, which is proof of concept. The work completed has revealed a new, prolific
style of mineralization at Mitu which is a very exciting find and adds to the already known mineralized
potential in the area.”
Targets Tested and Results
Mitu Trend
The Mitu Trend targets were developed based on the interpretation of airborne magnetic data which
highlighted a corridor of intense defor mation, about 8 – 10 kilometres wide, that includes numerous
northeast-trending structures which are also key to mineralization at the Kansanshi Mine.
Five widely spaced diamond drill holes were completed on the Mitu Trend targeting northeast-trending
mineralization settings at two localities within the wider Mitu Trend (Figure 1).
Drill holes MTDD -044 and MTDD- 045 are located approximately 500 metres apart and intersected
structurally controlled Cu-Co mineralization (Figure 1 & 2) including:
o 4.15m @ 2.28% Cu eq (1.29% Cu & 0.13% Co & 0.09% Ni) from 113.5m, in MTDD-044
o 5.80m @ 2.41% Cu eq (1.86% Cu & 0.07% Co & 0.02% Ni) from 119.2m, in MTDD-044
o 7.30m @ 0.79% Cu eq (0.58% Cu & 0.02% Co & 0.02% Ni) from 149.0m, in MTDD-045
Holes drilled to test the continuity of the historic intercept in hole MDD -17-15 which measured 4.23%
CuEq over 11.6 m (see the Company’s news release dated July 4, 2017 ) achieved a technical su ccess,
encountering sulphide minerals in fault breccia and the associated alteration zones broadly within the
target depth interval. A detailed assessment is underway to assess the complexity of the setting in which
this discovery was made.
Crunch Zone
The Crunch Zone exploration target is situated between the Kaz hiba Dome in the northwest and the
Solwezi Dome in the southeast (Figure 1) . Based on geophysical data , it appears a northeast trending
wedge of Copperbelt strata is ‘crunched’ between the domes showing interference fold pattern s that
abruptly terminate against the domal structures. An analysis of the VTEM electromagnetic survey
suggest mineralized fluids may have migrated along major faults or thrusts which occurred where the
Copperbelt strata encountered the dome structures.
An initial drill program consist ing of several drill traver ses to test for mineraliz ation as well as
determining the rock succession in the contact zones is underway at the Crunch Zone with seven holes
completed. No assays from these holes have been received yet.

Notes:
• Reported intervals are the downhole widths. M ore 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 $ 3.50/lb copper, $23.50/lb cobalt, and
$10.00/lb nickel and 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
Core s amples obtained from 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.
