Crystal Lake Discovers Porphyry Center Extending the Footprint of

Burgundy Ridge by 2.3km: Drills 56.35m @ 0.45% Copper, 0.33 g/t

Gold, and 3.44 g/t Silver

October 09, 2019, Vancouver, British Columbia - Crystal Lake Mining Corporation (TSXV:

CLM OTC: SIOCF FSE: SOG-FF) (“Crystal Lake” or the “Company”) is pleased to announce

the discovery of an entirely\new copper-gold (Cu-Au) porphyry mineral zone at the 72’ Zone; 2.3km

northeast of the Burgundy Ridge mineralization. This represents a new copper-gold (Cu-Au) rich

porphyry on the Newmont Lake Project located at the western margin of the Eskay Rift in the Heart

of the Golden Triangle, British Columbia.

This discovery is 250 metres west-northwest of historic high-grade Cu-Au skarn-type mineralization

drilled by the previous operator and ~2km away from newly discovered analogous mineralization

on surface at the Rock Islands indicative of a potentially large porphyry system. This is the first

discovery of porphyry-type mineralization at 72’ Zone, and the system remains open to depth and

along trend both to the north and south. (See Figure 1).

Maurizio Napoli, President / CEO of Crystal Lake commented “We are excited to see our initial

drilling campaign result in the discovery of a porphyry Copper-Gold system and expansion of the

Burgundy Ridge alteration system. The 2019 program has already provided promising data to vector

into the high-grade core of these large porphyry-hydrothermal systems.”

Highlights

• New Cu-Au-Ag porphyry discovery highlighted by 56.35 metres of 0.45% Cu, 0.33 g/t Au,

and 3.44 g/t Ag from 224.88 metres – 281.23 metres in diamond drill hole STDDH19-006.

• Strong potassic alteration centre of chalcopyrite-bornite within grading 22.28 metres of

0.89% Cu, 0.71 g/t Au, and 6.65 g/t Ag from 228.00 metres – 250.28 metres in diamond

drill hole STDDH19-006.

• Widespread alteration and sulphide mineralization associated with large Cu-Au-Ag porphyry

systems in the region intercepted in all four holes.

• High-grade chalcopyrite-bornite mineralization is relatively shallow compared to other

porphyry systems in the region.

• System may be evidence for high-grade porphyry-related skarn-type mineralization observed

on surface along the entire Burgundy trend.

A total of four, widely spaced diamond drill holes tested a 700m x 300m area. All of the holes

intercepted widespread sulphide mineralization and alteration styles characteristic of large porphyry

Cu-Au systems. The third diamond drill hole into the target area (STDDH19-006) cut through stock-

work hosted and disseminated chalcopyrite-bornite mineralization (“hypogene sulphide”) associated

with a potassic alteration zone. The 56.35 metre diamond drill core interval contains 0.45% Cu,

0.33 g/t Au, and 3.44 g/t Ag. Importantly, the intercept includes a zone of intense potassic alteration

and high-grade hypogene mineralization comprising 22.28 metres of diamond drill core

intercepted 0.89% Cu, 0.71 g/t Au, and 6.65 g/t Ag. It is suggested that this intercept may be an

early indication of the large Cu -Au-Ag porphyry system underlying the Burgundy Trend that is

responsible for driving fluids that generated the high-grade skarn mineralization observed at surface

along the trend. Further hyperspectral data supports the continuation of the alteration system in these

directions. (See Figure 1).

The new porphyry system was identified through an extensive field mapping and spectral geology

program that defined a large hydrothermal system focused around a multi-stage intrusive centre and

associated hydrothermal breccias. The presence of alteration and sul phide mineralization in the

adjacent diamond drill holes suggests the presence of a sizable hydrothermal system in the area.

STDDH19-006 is the first hypogene-only mineralization intercepted at 72’ Zone to date.

holes.

Cole Evans, President / CEO of HEG commented “This obviously represents an exciting and major

development over the Burgundy trend. HEG geologists worked diligently to develop a new lithology

and alteration map of the area supported by their hyperspectral technology never before used on the

property. We focused on defining a complex intrusion, breccia, and alteration paragenesis prior to

the initial target testing. Long intercepts of strong sulphide and white mica alteration in STDDH13-

003 and STDDH13-005, located nearly 600 metres and 450 metres respectively from STDDH19-006

is good evidence for the presence of a large porphyry system. The entire technical team is extremely

excited about these results. We feel this is one of a series of mineralization centres that have never

been drilled within the Burgundy system and might be the heat and fluid source behind high-grade

Cu-Au-Ag-Zn mineralization on surface along the entire 2.3km trend.”

Crystal Lake Provides Drilling and Work Update

A total of 6,546 metres of diamond drilling has been completed to date in 2019 at the Newmont

Lake Project. Completed drilling has been focused on the Burgundy Trend, and Newmont Lake Gold

Corridor. In addition, a massive grassroots exploration program and data interpretation program is

systematically being executed across the entire Newmont Lake Project. The following tables provide

shareholders a summary of the progress made so far:

variety of new showings and recent diamond drill core. Mineral identification has been determined

visually by geologists and cross-referenced via mobile X-ray Fluorescence elemental geochemical

techniques (ThermoScientific Niton XL5 pXRF). Portable XRF data is not provided as it is not an

indicator of representative geochemistry of the entire rock mass. The reader should also note that

while relative spatial information is provided, mineralization is not necessary representative of space

between any given location and it should not be assumed that lateral continuity exists. The reader is

encouraged to exercise caution, due their due diligence, and determine their own conclusions with

the information provided.

QAQC/ Analytical Procedures

Rock samples from the Newmont Lake Project were sent to MSA L ABS’ preparation facility in

Terrace, B.C., where samples were prepared using method PRP-910. Samples were dried, crushed

to 2mm, split 250g and pulverized to 85% passing 75 microns. Prepped samples were sent to MSA

LABS’ analytical facility in Langley, B.C, where 50g pulps were analyzed for gold using

method FAS-121 (fire assay-AAS finish). Gold assays greater than 100 g/t Au were automatically

analyzed using FAS -425 (fire assay with a gravimetric finish). Rock samples were analyzed for

53 elements using method IMS -230, multi -element ICP-MS 4 -acid digestion, ultra -trace level.

Silver assay results greater than 100 g/t Ag and cobalt, copper, nickel, lead and zinc greater than

10,000ppm were automatically analyzed by ore grade method ICF-6.

Crystal Lake Mining conducts its own QA/QC program where three standard reference material

pulps, two blank reference material samples are inserted for every 100 samples when analyzing

rock samples.

Soil samples from the Newmont Lake Project were sent to MSA L ABS’ preparation facility in

Terrace, B.C., where samples were prepared using method PRP-757. Soil samples were dried and

screened to 80 mesh, discard plus fraction. Prepped samples were sent to MSA L ABS’ analytical

facility in Langley, B.C, where they were analyzed for 51 elements using IMS-131 for samples

with 20g or greater and IMS-130 for samples between 0.5g and 20g.
