Crystal Lake Maiden Drilling at Burgundy
Ridge Confirms Copper-Rich New Discovery

/CNW/ -
Crystal Lake Mining Corporation
(
TSXV: CLM
, the
"
Company
" or "
Crystal
Lake
"), is pleased to announce that results from first-ever drilling last fall at
Burgundy Ridge confirm a new grassroots discovery in the footprint of approximately two dozen
showings and mineral zones at the Company's 430 sq. km Newmont Lake Project northwest of
Eskay Creek
.
Widespread surface mineralization at Burgundy Ridge extends to depth, including
2.6% copper
between 118 meters and 119.5 meters
in the fourth and final shallow hole, in a
multi-element
copper-rich porphyry-skarn system
.
Burgundy Ridge is now believed to be part of a >3 km-long northeast trending mineral corridor
situated west of a series of under-explored high-grade gold occurrences and targets, along with the
historic Northwest gold zone. Importantly, all of these mineral zones and associated host rocks are
within a graben structure bounded by the 20-km-long McLymont Fault. This makes the Newmont
Lake Project a highly favorable geological environment for new discoveries.
Reverse circulation (RC) first-pass drilling of four shallow holes totaling 550 meters was completed
from one set-up at the top of Burgundy Ridge as restrictive winter conditions set in at an elevation of
approximately 1,900 meters.

Each hole intersected copper-rich mineralization, with gold and silver, associated with intense
and widespread "skarn style" alteration of the multi-phase intrusions and immediate host rocks;
Evidence suggests that mineralization strengthens with depth;
Drilling confirmed a previously unmapped and well-endowed intermediate intrusive rock
consisting of pervasive chalcopyrite blebs and fine-grained disseminated bornite mineralization.
Richard Savage
, President and CEO, commented: "The cover has been lifted off Burgundy Ridge
with geologists fascinated by their first look at what's below surface at a dynamic target that not
long ago was completely hidden by snow and ice.
"To have hit on each hole in maiden drilling during extremely challenging conditions last fall,
confirming a new early stage discovery high in the system in this prolific district, gives us a huge
edge entering our 2019 diamond drilling program and sets the table for a potential major new find,"
Savage concluded.
High-Energy Mineralized System
Impressive surface alteration and mineralization at Burgundy Ridge, exposed by a rapidly receding
glacier, has been mapped over several hundred meters and is now known to extend to depth
following first-ever drilling. This new discovery is on trend with the '72 Zone, Telena and Andrei
targets which show similar characteristics as Burgundy Ridge based on mapping, surface sampling
and geophysics. All areas will be explored aggressively in 2019.
Multiple surface targets exist at Burgundy Ridge including a lower elevation higher-grade zone,
identified through sampling, providing ample additional discovery opportunities in 2019 as glacial
retreat accelerates and diamond drilling tests this mineralized system over a broader area and at
much greater depths.
Tight correlations between copper and silver, copper and gold, and copper and cobalt are indicative
of a coherent style of mineralization created through a systematic process, elevating the potential of
the Burgundy Ridge system. Meanwhile, the copper-gold rich skarn at the interface between
mineralized intrusions and carbonate rocks at Burgundy Ridge reflects a higher fluid-rock ratio typical
of proximal skarn along a porphyry system.
Zoned calc-silicate skarns are commonly formed
from fluids associated with very large porphyry systems.

QA/QC Statement on Assay Results
Crystal Lake
employed rigorous Quality Assurance and Quality Control (QAQC) protocols in line with
best industry standards and practices for geochemical analysis. In the field, three rotating standards
and a blank were inserted every 25th sample. Three types of standards were purchased from Ore
Research & Exploration Laboratories Pty Ltd (ORE). A common granite-gravel aggregate was used
as a blank. Additionally, MS Analytical used in-house blanks, and added two sets of duplicates to
further improve the QAQC methodology. Two aggregate blanks were analyzed before each hole to
ensure proper cleaning between sample batches. Up to six duplicates per hole were used to test
FAS-211, ICP-240 and IMS-230 assay results. Both reject and pulp duplicate tests were performed.
Samples were prepared at MS Analytical in
Terrace, BC
, using PPU-510 (Pulverize 250g to 85%
passing 75-micron) due to the lack of crushing required for RC chips. The sample pulps were then
transported to MS Analytical Laboratory in
Langley, BC
, for geochemical analysis. A FAS-211
analysis (Gold by Fire Assay and AAS finish) was used with detection up to 100 ppm with an over
limit analysis FAS-415 (Detection up to 1000 ppm). Gold is reported in parts per million (ppm)
equivalent to grams per tonne (g/t). ICP-240 analysis was used as a 33-element ore-grade
geochemistry method, therefore no over limit analysis was necessary (four-acid digestion with
ICPES finish). These analytical results are reported in percentage apart from silver (Ag), which is
reported as parts per million (ppm). Silver analysis was retested using IMS-230 to provide a lower
detection limit of 0.01 ppm to ensure accurate findings.
