NEWS RELEASE
October 17, 2017 Symbol:-TSX-V: CLM
Geological Update
Vancouver, BC – Crystal Lake Mining Corporation (the “Company ”) is pleased to announce a
property review based on outcrop and drill core samples at the EL1 mining patent optioned by
Crystal Lake Mining Corp. The technical review was undertaken by Dr. Peter C. Lightfoot of
Lightfoot Geoscience Inc.
Drill core and surface samples from the EL1 propert y contain disseminated through semi -massive
magmatic-textured pyrrhotite, pentlandite, and chalcopyrite mineralization hosted by gabbro . The
semi-massive sulfide mineralization and mafic inclusions comprise a magmatic breccia with in a
broader unit of gabbr o with disseminated sulfide . These geological relationships are commonly
encountered in magmatic sulfide ore deposits and support the importance of effectively testing the
rocks developed above the contact of the intrusion beneath the EL1 mineralization.
Mineralized gabbros have been encountered at depth below EL1, but exploration has not yet
defined the lower contact of the intrusion, and has not tested the potential development of massive
sulfide mineralization that often occurs in depressions and/or fe eders at the lower contact of
intrusions and in association with wider halos of disseminated sulfide mineralization.
Dr. Peter Lightfoot, technical advisor for ELDC, the geological contractor to Crystal Lake Mining is
ramping-up a program of exploration to identify electrically conductive target zones that may
correspond to high grade mineralization adjacent to and beneath the historic mineral resource. The
concentration of nickel in the sulfide portion of samples derived from the near -surface historic
resource (i.e. the Ni tenor of the sulfide) is between 3 and 4 wt% Ni in 100% sulfide, and this
encourages a search for high grade massive nickel-rich sulfide at depth on the EL1 patent property.
The exploration strategy is designed to test this target, and will include a combination of s diamond
drilling coupled with borehole and surface electromagnetic methods designed to focus exploration
in a search for mineralization with elevated Ni, Cu, Co and precious metal concentrations.

1.2m interval from NQ drill hole A04- 15 grading 2.29%Ni, 0.24% Cu, and 0.15%Co. The
association of magmatic breccias with nickel sulfide mineralization is a recognised feature of
many world-class magmatic sulfide ore deposit.
