Midnight Sun Drills 4.23% Copper Equivalent Over 11.6 Meters
Midnight Sun Drills 4.23% Copper Equivalent Over 11.6 Meters
Vancouver, British Columbia, July 4, 2017 - Midnight Sun Mining Corp. (the "Company" or "Midnight
Sun") (TSX-V: MMA) is pleased to announce initial assay results from its spring 2017 Mitu drill program.
The focus of this drill campaign wa s to expand and further define the extent of the previously
announced ore-shale type copper -cobalt discovery at the Mitu area of the Solwezi Properties , Zambia
(see news release dated January 12, 2017 ). Drill hole MDD -17-15 stepped out 3.72 kilometers (“km”)
southeast from discovery hole MDD -16-01, and reported 3.44% copper, 0.067% c obalt, 0.058% nickel
and 331 parts per billion (“ppb”) gold (4.23% copper equivalent) over 11.6 meters (“m”).
“This was an ambitious program, with wide step out holes both along strike and down dip from known
mineralization. Our aggressiveness was rewarded with the best hole we have drilled to date. ” said
Robert Sibthorpe, President and CEO. “The fact that we continue to encounter strong copper and
significant cobalt reinforces our belief that Mitu is worthy of our excitement . With the advancement in
prices and increase in demand for cobalt, this project appears to be as important a cobalt discovery as it
is a copper one.”
The results from the first eight diamond drill holes receiv ed as well as significant results from Air Core
drilling are presented in the Table below.

Notes;
• MDD-17-02 did not report any significant results.
• True widths were estimated using cross-section analysis.
• Copper equivalents were calculated using current metal price ratios and are presented only for ease of interval
comparison. Rec overy factors were assumed at 100% although the recovery factor for various metals may vary
significantly. Metal prices used were $2.54/lb copper, $26.54/lb cobalt, $4.03/lb nickel and $1251/oz gold.
• *Denotes near surface oxide mineralization.
To date, the 2017 work program at Mitu has comprised 37 line-km of natural source audio magneto
tellurics (“NSAMT”) geophysical surveying, air core and diamond drilling , and soil sampling. The NSAMT
survey indicated the presence of a conductive anomaly over a strike length of approximately 17 km. This
conductive anomaly is believed to be associated with ore-shale, the typical host rock for copper
mineralization in the Zambia-Congo Copperbelt . Midnight Sun has taken 648 in -fill and step -out soil
samples and First Quantum Minerals has continued soil sampling and geochemical work covering the
Solwezi Properties as part of a larger regional program , of which the results are reported to Midnight
Sun on a timely basis (see news release dated August 18, 2016). Prior to diamond drilling, using air core
drills, the Company drilled 4,755 m in 119 shallow drill holes to bedrock for indications of ore-shale
covering the conductive anomaly indicated by the geophysical survey. This air core drilling confirmed the
ore-shale’s correlation to the geophysical anomaly, extending the known strike length by more than 10
km, and assisted in collaring the diamond drill holes.
Qualified Control/Quality Assurance : Samples obtained during both core a nd AC drilling were
transported directly to Genalysis Laboratory Services in Chingola, Zambia by Midnight Sun personnel for
sample preparation. Samples were sorted, dried, crushed, and pulped before being sent to Perth,
Australia for final chemical analysis using ICP -OE methods. All samples returnin g >10,000 ppm Cu were
automatically re-checked by Genalysis which is a fully accredited laboratory . Standards and blanks were
inserted regularly in the sample stream and checks were done for Au and Cu.
