Crystal Lake Drills Broad Zones of Copper, Gold, Zinc, Silver
Mineralization and Mineralized Breccia at Burgundy Ridge, in BC’s
Golden Triangle
June 22nd, 2020, Kelowna, British Columbia – Crystal Lake Mining Corporation (TSXV: CLM OTC: SIOCF
FSE: SOG-FF) (“Crystal Lake” or the “Company”) is pleased to report additional copper, gold, silver,
zinc, and lead mineralization and the first high-grade gold mineralization intersected from its maiden
diamond drill program that tested 3 target areas at Burgundy Ridge; an area within the greater
Burgundy Trend of the Company’s Newmont Lake Property in the Golden Triangle of northwest
British Columbia, Canada.
This is the first in a series of planned news releases reporting assay results and ongoing geological
and geophysical 3D modelling of multiple systems across the Company’s Newmont Lake Project.
Subsequent technical news releases will focus on providing further geological and geophysical
information outlining system connectivity and the regional project wide potential prior to our 2020
exploration programs.
Green Rock Zone
Diamond drill hole BR19-16 is the only hole to date targeting the Green Rock breccia which was
discovered late in the 2019 season where receding snow and ice allowed additional mapping .
Mineralization encountered 260 meters below and 75m offset from a high-grade surface trench
taken at the same time included:
51.38m of 0.46% Cu, 1.22% Zn, 0.17 g/t Au, 9.98 g/t Ag, and 0.16% Pb starting at 343.66m.
Including 30.33 metres of 0.64% Cu, 2.00% Zn, 0.25 g/t Au, 13.57 g/t Ag, and 0.25% Pb
The drill interval demonstrates mineralization extends under areas of receding ice and snow with
significant depth potential. Green Rock was identified as an area of interest in September 2019 from
mineralization in the previously announced trench sample BRCH19-01 that cut a continuous interval
assaying:
37.00m of 1.31% Cu, 2.97% Zn, 1.49 g/t Au, and 23.26 g/t Ag,
including 22.00m of 2.00% Cu, 4.69% Zn, 2.27 g/t Au, and 34.36 g/t Ag
Evidence at the Green Rock zone suggests a minimum of 3 mineralizing events in the area and is
characteristic of high-grade hydrothermal breccias seen in large alkalic porphyry-type deposits. Clasts
within the hydrothermal cement include k -feldspar and hematite altered syenites hosting
disseminated and stockwork chalcopyrite. This is further evidence for alkalic porphyry hypogene
mineralization underneath Burgundy Ridge pre-dating the multi-stage Green Rock breccia. BR19-16
is also the first evidence of lead in the Green Rock breccia with individual grades as high as 3.58% Pb,
1.01% Cu, 2.80% Zn, 0.21 g/t Au, and 47.48 g/t Ag over 1.16m starting at 351.35m.
Figure 1: A’-A section of Green Rock Zone on the southern edge of Burgundy Ridge. Evidence
suggests the potential for a large, high-grade, multi-element breccia; a critical component of alkalic
porphyry systems.
Ridge Zone
Diamond drill hole BR19 -13 drilled 250 metres north of Green Rock intersected an interval of
184.67m of 0.21% Cu, 0.14 g/t Au, 3.70 g/t Ag, and 0.17% Zn starting at surface with grades as high
as 8.98% Cu, 2.36% Zn, 0.62 g/t Au, 35.97 g/t Ag. Mineralization consists of disseminated and vein-
hosted chalcopyrite locally weathering to chalcocite/malachite near-surface in “skarn-like” alteration
and lithology . Intervals of high -grade mineralization are locally massive chalcopyrite with
disseminated and vein-hosted chalcopyrite, sphalerite, and pyrite thought to be distal offshoots of
Green Rock breccia mineralization.
BR19-13 is located 200m SSW from previously announced BR19-02 which intersected 91.26m of
0.38% Cu, 0.30 g/t Au, and 4.12 g/t Ag starting at 36.67m. Ridge Zone drilling outlines skarn-style
mineralization over a 600m strike length and is open in both strike directions and at depth.
37.00m of 1.31% Cu, 1.49 g/t Au, 23.26 g/t Ag, and 2.97% Zn on surface
Including 22.00m of 2.00% Cu, 2.27 g/t Au, 34.36 g/t Ag, and 4.69% Zn
Including 10.00m of 3.29% Cu, 3.75 g/t Au, 8.59% Zn, and 63.40 g/t Ag
51.38m of 0.46% Cu, 1.22% Zn, 0.17 g/t Au, 9.98 g/t Ag, and 0.16% Pb @ 343.66m
Unexplored, No Data.

Ridge from receding ice. See Figure 5 and 6 for more details.
Ridge West Zone
Diamond drill hole BR19-04 intersected 1.50m of 15.05 g/t Au and 4.03 g/t Ag starting at 149.00m
depth. These are the first signs of a potential high-grade gold system adjacent to the current target
area and is the second of two targets which were intersected underneath receding ice and snow.
Little is known about the high-grade gold mineralization at this time.
Further drilling at Ridge West successfully intersected what are thought to be additional offshoots of
the Green Rock breccia more than 400m away from the theorized epicentre. Grades as high as 1.00m
of 6.70% Cu and 55.9 g/t Ag within 2.60m of 3.64% Cu and 32.32 g/t Ag were encountered at
262.35m.
Diamond drill hole BR19-04 intersected strong k-feldspar alteration within a narrow syenite dyke
haloed by strong biotite alteration of the host volcanic rock averaging 0.41 g/t Au, 1.64 g/t Ag, and
0.07% Cu in the final 23.00m of the 438.00m deep diamond drill hole. Localized biot ite alteration
graded as high as 1.74 g/t Au, 5.04 g/t Ag, and 0.09% Cu over 4.6m. The drill hole was unable to
continue due to logistical constraints, but casing and the drill pad remain in place for re-entrance.
This intersection provides important geological data for vectoring into the centre of alkalic porphyry
mineralization at Burgundy Ridge.
Cole Evans, Crystal Lake’s CEO commented: “Drilling from the maiden diamond drill program at
Burgundy Ridge is shallow and minimal relative to the size of the property and the scale of alkalic
copper-gold porphyry deposits that we are modeling and targeting at Burgundy. Strong surface and
near surface miner alization with alteration intersected thus far confirm the presence of well
mineralized alkalic porphyry systems along the 2.3km Burgundy Trend. Our results indicate geological
similarities to alkalic porphyry deposits like Cadia/Ridgeway, North Parkes, Galore Creek, Red Chris,
Mt. Milligan, and Mt. Polley.
Part of what makes alkalic porphyry deposits rare worldwide is the time and difficulty of exploring for
them. Our team has already demonstrated its ability to find significant mineralization without any
geophysical aids to date, and to execute our work programs under challenging conditions in the area.
I am happy with the progress so far at Burgundy and the results we are seeing warrant further
exploration. Future work at Burgundy will focus on vectoring into the centres of our alkalic porphyry
mineralization.”
Geological Discussion and Photo Gallery
The 2019 maiden diamond drill program intersected mineralization in 9 of 10 diamond drill holes
characterizing several different mineralization styles and associated elements. The following is a brief
geological discussion. In-depth details will be outlined in a series of upcoming technical presentations
for Newmont Lake.
Most of the mineralization drilled thus far is adjacent to the Stikine volcanic limestone contact
providing a significant skarn component to mineralization to date. Higher grade intercepts appear to
be “off -shoots” of a heterolithic, hydrothermal breccia cemented by chalcopyrite, pyrite, and
sphalerite with significant localized biotite alteration (see Figure 3). Intercepts of this style were
observed in 9 of 10 drill holes at Burgundy Ridge of varying widths. It is hypothesized this well -
mineralized breccia is sourcing in the vicinity of the Green Rock area. Clasts within the hydrothermal
breccia are indicative of k -feldspar and/or hematite altered syenites that can host disseminated
chalcopyrite or fine chalcopyrite stockwork. Burgundy Ridge consists of a suite of porphyritic,
trachytic, and megacrystic syenites striking ~SSW dipping 55 to 75 NE. They intrude what appears to
be an earlier pseudoleucite -phyric phase. A >1.0km wide epidote -garnet +/ - diopside breccia
dominates most of Burgundy Ridge.
Figure 3: Example of strong biotite alteration associated with hydrothermal breccia mineralization
cemented with chalcopyrite, pyrite, and sphalerite at 144.86m depth in BR19-16 (9th of 9 diamond
drill holes completed at Burgundy Ridge to date) Note k -feldspar altered syenite clasts within the
hydrothermal breccia are indicators of a potassic zone at depth.
Figure 4: K-feldspar altered rock with chalcopyrite stockwork adjacent to the Green Rock
hydrothermal breccia grading 0.46% Cu, 0.53 g/t Au, 10.33 g/t Ag, and 0.32% Zn over 7.00m on
surface. Potassic alteration pre -dates the hydrothermal breccia. Zinc content is associated with
crosscutting veins of the Green Rock breccia. Winter conditions shut down trench sampling and
mineralization remains open.
New surface discoveries in 2019 highlight additional areas of interest immediately north of Burgundy
Ridge. Mineralized megacrystic to porphyritic syenites have been observed on surface for the first
time resulting from receding snow and ice in the area (see Figure 4 and 5).
Diamond drill hole BR19-04 intersected strong k-feldspar alteration within a narrow syenite dyke
haloed by strong biotite alteration of the host volcanic rock averaging 0.41 g/t Au, 1.64 g/t Ag, and
0.07% Cu in the final 23.00m of the 438.00m deep diamond drill hole. Localized biot ite alteration
graded as high as 1.74 g/t Au, 5.04 g/t Ag, and 0.09% Cu over 4.6m. This intercept has great technical
significance as it is the first sign of biotite/k -feldspar alteration that is not associated with
hydrothermal breccia activity and could be considered typical hypogene mineralization expected in
alkalic porphyry deposits.
In conclusion, the early evidence to date suggests Burgundy Ridge shares many features of a large,
silica-undersaturated, alkalic porphyry system with similar geological characteristics to both
Newmont/Teck’s Galore Creek Project located 35km northwest, and Imperial Metals’ Mt. Polley Mine
located in British Columbia’s central interior 400km north of Vancouver, Canada. The Company is
currently studying geochronology and paragenetic relationships at the University of British Columbia
Okanagan’s FiLTER Laboratory (Fipke Laboratory for Trace Element Research) in Kelowna, Canada.
