Crystal Lake Mining’s Discovery Team Outlines Chachi Corridor

Copper-Gold Target Area at Newmont Lake Project

June 12, 2019, Vancouver, British Columbia - Crystal Lake Mining Corporation (TSXV:

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

that a large copper-gold porphyry target area, with high-grade gold potential, has been outlined on

the eastern side of the Company’s Newmont Lake Project in Northwest B.C.’s Eskay Camp.

The northeast trending Chachi Corridor along the McLymont fault system has a current strike length

of greater than 8 km by 3 km wide as defined by an extensive review of historic data including rocks,

soils and geophysics. The entire corrido r, which features astonishing glacial retreat, is n otably

underexplored and will be one of several primary areas of focus for the 2019 summer exploration

program, now underway.

Location

The Chachi Corridor begins approximately 6 km northeast of the historic Northwest Gold zone

(“NW Zone”) and 20 km northeast of Crystal Lake’s recent drilling discovery at Burgundy Ridge

(March 7, 2019, news release), underscoring both the scale and potential of the entire 430 sq. km

Newmont Lake Project located in the heart of the Golden Triangle.

A broad and flat glacial valley ranging in elevation from 500 to 700 meters begins at the northeast

tip of the Chachi Corridor and continues in a straight direction northeastward for approximately 20

km to the Galore Creek access road west of the Bob Quinn Airstrip. Additionally, infrastructure and

access to the southern portion of the Newmont Lake Project have recently been upgraded with the

completion and power production of AltaGas’ Northwest Hydroelectric facilities, including the 66-

MW McLymont Creek power plant which sits at the southern tip of Crystal Lake’s land package 15

km northwest of Nickel Mountain.

Glacial Retreat Opens Corridor

Based on cross referencing old and new satellite imagery and orthographic photos, glacial retreat of

approximately 2 to 4 kilometers has occurred within the Chachi Corridor since parts of it were last

explored with “boots on the ground” in 2008. Widespread surface alteration, intrusive bodies and

other geological features consistent with large-scale porphyry copper-gold and associated shear vein

gold and/or carbonate replacement gold systems are apparent in the geochemical data compilation.

This plus the newly exposed prospective ground makes the entire Chachi Corridor a high-priority

target.

Chachi Corridor Additional Highlights:

• Three separate intense geochemical anomalies (copper, gold and silver), vectoring into vast

unexplored and highly altered terrain, covering an area greater than 8 km by 3 km;

• An approximate 3 km gossanous zone is adjacent to a cluster of dioritic and syenitic

intrusions (typical intrusion types to host large porphyry systems and mineral occurrences in

this region), all spatially associated with the McLymont Fault system of extensional tectonics

in the region;

• A radiometric age-dating study at the University of British Columbia (“UBC”) concluded

late Triassic ages of 203.1 ± 2.0 Ma to 214.1 ± 2.0 Ma on two sampled intrusions to date in

the Chachi Corridor, which puts a copper-gold porphyry system in the Corridor remarkably

similar in age to the Newmont/Teck Galore Creek/Copper Canyon deposits approximately

40 km to the northwest (Assessment Report #30749, B.C. Geological Survey);

• Limited historic rock sampling (late 1980’s) over a strike length of 1 km from an interpreted

epithermal area on the eastern side of the Chachi Corridor returned values ranging from

anomalous to 14.2 g/t Au, with 8 of the 28 samples grading >8 g/t Au (Assessment Report

#18450).

Richard Savage, President and CEO of Crystal Lake, commented: “The right people, the right area,

the right time - we’ve assembled an amazing team that’s planning an expansive initial exploration

program that will be systematic and discovery -driven, applying state -of-the-art exploration

technologies.”

Chachi Phase 1 Exploration Program

A team of approximately 20 people at any given time will be exploring and validating the Chachi

Corridor. A Phase 1 program consisting of extensive prospecting, lithological and alteration

mapping, airborne and ground geophysics, and geochemical and alteration vectoring using the latest

in-field mobile hyperspectral and X-ray Fluorescence (“XRF”) technology should quickly define

priority targets for drill testing this summer.
