March 18, 2019, Vancouver, British Columbia – Crystal Lake Mining Corporation (the “Company” or “Crystal Lake”) is pleased to announce the following corporate developments:

Hard Dollar Private Placement Increased To $3.5 Million

Due to investor demand, Crystal Lake has increased its recently announced non-brokered hard dollar private placement financing (“Unit Private Placement”) from $3.0 million to $3.5 million (please refer to March 15, 2019, news release). Subscription agreements have been received for $3,465,500 (15,402,220 units @ $0.225 per unit) and official closing of this private placement is expected in the next several days. Each unit consists of one common share in the capital of the Company and one share purchase warrant. Each warrant will entitle the holder to purchase one share of the Company for a period of 24 months from the closing of the offering at an exercise price of $0.35 per share.

The Unit Private Placement is subject to an acceleration provision that states that in the event that the closing price of the Company’s shares on the TSX Venture Exchange (the “TSXV”) (or such other exchange on which the Company’s Shares may become traded) is $0.75 or greater per share during any fifteen (15) consecutive trading day period at any time subsequent to four months and one day after the closing date, the warrants will expire at 4:00 p.m. (Vancouver time) on the 30th day after the date on which the Company provides notice of such accelerated expiry to the holders of the warrants.

$500,000 Flow-Through Financing

The previously announced non-brokered flow-through private placement (“FT Private Placement”) for up to $500,000 at $0.35 per unit (refer to March 15, 2019, news release), which included a full warrant exercisable at $0.45 per share for a period of 24 months from the closing of the FT Private Placement, has been replaced by a $500,000 flow-through private placement at $0.32 with no warrant. Subscription agreements have been received for $470,000 (1,468,750 flow-through shares) and the full $500,000 is expected to officially close shortly.

Finder’s fees will be paid to qualified parties. All securities will be subject to a four-month hold period from the closing date. The private placements are subject to the approval of the TSXV.

Proceeds from the Unit Private Placement will be for general working capital purposes and to complete the first phase of Crystal Lake’s 2019 drilling and exploration program (at least $3 million) at the Newmont Lake Project in the Eskay region, optioned from Romios Gold (RG: TSXV), starting in Q2.

Proceeds of the FT Private Placement will be used to further advance the Company’s projects in Northwest British Columbia and Northwest Ontario.
