Midnight Sun Mining Corp. Announces Initial VTEM Interpretation
Vancouver, British Columbia, March 4, 2019 -- Midnight Sun Mining Corp. (the "Company"
or "Midnight Sun") (TSX -V: MMA) is pleased to announce initial interpretive results from a
3,889 line-kilometre Versatile Time Domain Electromagnetic airborne geophysics (“VTEM”)
survey conducted on the Solwezi Licences in Zambia (the “Property”).
The VTEM survey has provided anomalous responses in several areas, providing the
Company with previously unknown exploration targets as well as expanding the size of
known targets.

“This survey and subsequent interpretive work is invaluable in my opinion . Combining the
VTEM survey with existing drill and exploration data, we can now: 1) better understand why
previous drill holes did or did not encounter mineralization , 2) see that the known
mineralized targets are even larger than we had expected, and 3) identify well-defined
anomalous zones in previously untested and unexplored sections of the Property. By
combining the VTEM interpretations with existing data we can now gain a better
understanding of the geology and controls for potential mineralization on the Solwezi
Licences” states Al Fabbro, Lead Director & Acting CEO.
The following illustrates and summarizes, by target area, the initial interpretations from the
VTEM.
Mitu
To date, drilling and other work at Mitu has encountered what appears to be only one of the
anomalous target areas, M1 , which was the initial Mitu discovery zone. The identified M1
conductor is approximately 1km in strike and 500m in dip. The VTEM interpretation has
delineated 5 other (6 in total) discrete conductors which occur near or within the favourable
Upper and Lower Roan contacts and 2 of these other anomalous zones appear considerably
larger than M1.

“The original discovery at Mitu, which was made based on a subtle geochemical anomaly, is
a remarkable testament to the early work of our technical team. Seeing the collection of
even stronger anomalies that continue down the Mitu trend has the Midnight Sun team
very excited for the next exploration campaign” stated Wayne Moorhouse, COO.
Western Flank
Approximately 15km northwest of Mitu , the VTEM survey has identified the largest
continuous conductive trend on the Property, with approximate dimensions of 5km strike by
2km dip. This conductive trend represents a potential new discovery and occurs in the same
geology as that surrounding the neighbouring Kansanshi Mine.
“We were very surprised to see this prominent anomaly in the VTEM data, as the Western
Flank represents a brand new target area on the Solwezi Licences. Very little historical work
has been performed here by previous operators, and the massive siz e and scale shown by
this interpretation makes it clear that appropriate investigation and attention is warranted”
said Mr. Fabbro.
22 Zone
Two anomalies in the 22 Zone area have been identified by the VTEM survey , neither of
which have been directly drill tested. The northern anomaly (A) indicates a strike length of
1.2 - 1.5km and the profile suggests a deeper conductor.
The southern anomaly (B) is within what appears to be a large dome which was previously
unmapped and unidentified. The VTEM suggests a thicker anomalous zone, on trend with a
major fault.

Early time conductor VTEM response and geology.
The response is indicative of doming in this area, similar to that which is associated with Kansanshi.
Mr. Moorhouse commented, “Anomalies A and B around the 22 Zone represent an
important step in the understanding of the mineralization in this area and will play a

significant factor in the exploration plan to follow up on the high grade oxide intercepts
drilled in 2013 -2014. Identifying what appears to be a previously unrecognized dome
validates speculative theories that the 22 Zone could be a Kansanshi analogue and makes us
very eager to get back to work in the area.”
Kifubwe
The VTEM survey identified what appears to be a chain of several discrete conductive zones
located around the Kifubwe area, all of which appear to be shallow and located in
favourable geology. The anomalies in this area correspond well to a 6km geochemical
anomaly previously identified by Midnight Sun.
Dumbwa
Despite the fact that this area represents the largest and strongest geochemical copper
anomaly reported in the country, it is located in a geological environment unlikely to
respond to the VTEM system, and as such t here does not appear to be a correlation
between known mineralization and a VTEM con ductor or spectrometer response in the
Dumbwa area. However, the information from the VTEM survey data has helped identify
and delineate the complex structures in this area which are believed to be the controls
necessary for potential mineralization.
About the VTEM Survey
The helicopter-borne VTEM ™ Plus B-field Horizontal Gradiometer and Radiometric
Geophysical survey was conducted by Geotech Airborne Ltd. of Aurora Ontario. The survey
covered 3,889-line kilometres covering the entirety of the Property. The survey was flown
using a combination of 100 and 200 metre spacings between June 20 and July 29, 2018.

As per Geotech Airborne Ltd.’s web site “VTEM ™ generates currents that diffuse into the
earth and, similar to water, always ta ke a path of least resistance. Conductive material
absorbs the currents and releases a secondary field that the VTEM ™ system measures. A
strong conductor absorbs and releases more or all the VT EM™ signal. A weak conductor
absorbs and releases some or none of the VTEM™ signal.”
By analysing the data generated by the VTEM survey a trained technician can identify
conductive zones within favourable geology. The VTEM interpretation was prepared by
Stephen Balch, P.Geo. of Balch Exploration Consulting Inc. The strong VTEM anomalies are
thought to be caused by conductive, graphite -rich shale units that are often the host to the
disseminated copper deposits that occur along the Zambia-Congo Copper Belt.

About the Property
Midnight Sun has earned a 60% interest in the Solwezi Licences with the potential to acquire
the remaining 40%. The Solwezi Licences are comprised of two individual exploration
licences totalling 506 square kilometres, situated in the North -Western Province of Zambia,
adjacent to First Quantum’s Kansanshi Mine; Africa's largest copper mining complex, on the
prolific Zambia-Congo Copper Belt.
