Crystal Lake Intersects 15.11 g/t Gold over 8 Metres at Newmont Lake Project, BC

Drill Results

Crystal Lake Intersects 15.11 g/t Gold over 8 Metres

at Newmont Lake Project, BC

September 18th, 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 intersection of shallow high -grade gold mineralization at Crystal Lake’s Newmont

Lake Gold Corridor. The new results are crucial as they provide evidence of a thick unit of unusually

high-grade gold mineralization within a broad envelop of continuous low-grade gold mineralization.

This discovery is important as it demonstrates that the mineral zone actually increases in both width

and in grade in areas where previous models indicate a narrowing of the mineral zone. Additionally,

a second deeper horizon has been intersected in an area without gold mineralization in previous

models adding to the exploration potential of the Newmont Lake gold corridor along the western

flank of the Eskay Rift in NW BC.

The first diamond drill core assay results from ongoing drilling at the NW Zone underscore the

potential for higher grades and increased continuity of grade which can result in significant

expansion of the historic mineralization while brand new high-grade domains are targeted elsewhere

along the gold-bearing McLymont Fault and numerous associated splay faults.

Highlights:

• The second of three drill holes, building on the northern extension of the Northwest zone,

intersected 15.1 g/t Au over 8.03 metres (106.32 metres to 114.35 metres), including 76 g/t

Au over 1 metre, in addition to an even shallower high-grade intercept of 7.6 g/t Au, 23.1 g/t

Ag and 1.03% Cu over 5.30 metres starting just 82 metres downhole (including 26.1 g/t Au

over 1.3 metres);

• These two shallow high grade gold zones form a thick continuous intercept of 44 metres (82

metres to 126.13 metres, approximate true width) grading 4.03 g/t Au, 4.06 g/t Ag and 0.29%

Cu, in addition to a deeper wide interval of disseminated gold mineralization (77 metres @

0.29 g/t Au) starting 157 metres downhole which points to the potential for new discoveries

including more high-grade mineralization at depth;

• Ongoing drilling of this significantly upgraded portion of the NW Zone Historic Resource*

has encountered visually similar mineralization in the third hole completed along section

with an estimated down-dip step out of approximately 22 to 30 metres. Assays are pending.

• The fourth hole on section in the Newmont Lake Gold Corridor is ongoing.

Dr. Peter Lightfoot, Technical Adviser to Crystal Lake, commented: "The western flank of the

Eskay Rift is endowed with significant high-grade mineralization styles that fit with a wide range

of deposit models, and require very efficient pathways for fluids and magma to migrate from depth

to the surface and form ore deposits. The gold mineralization developed along the western flank

of the Newmont Lake graben is part of this wider mineral system, and Crystal Lake is aggressively

developing an understanding of how the high-grade gold mineralization relates to the McLymont

fault, its subsidiary faults and associated hydrothermal breccias.”

Qualified Person

The technical information in this news release has been reviewed and approved by Mr. Maurizio

Napoli, P. Geo., VP Exploration for Crystal Lake Mining, a Qualified Person responsible for the

scientific and technical information contained herein under National Instrument 43-101 standards.

Quality Assurance/Quality Control

Drill core samples from the Northwest Gold Zone were sent to MSALABS' preparation facility in

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

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

to MSALABS' analytical facility in Langley B.C., where 50g pulps were analyzed for gold using the

FAS-211 method, fire assay AAS finish. Core samples were analyzed for 53 elements using the

IMS-230 method, multi-element ICP-MS 4-acid digestion, ultra fine 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 progr am where five standard reference material

pulps, five blank reference material samples, and two field duplicates are inserted for every 100

samples when analyzing core samples.
