Guyana Goldstrike Inc. Closes Final Tranche of Oversubscribed Non-Brokered Private Placement

In aggregate with the closing of the first and second tranche of the Placement, announced February 17th and March 16th, 2021 respectively, the Company has now issued 27,112,500 Units, for gross proceeds of $2,711,250.

Each Unit consists of one common share of the Company (a "Common Share") and one Common Share purchase warrant (a "Warrant"), with each Warrant entitling the holder to purchase an additional Common Share at a price of $0.15 per share for a period of thirty-six months following the closing of the Placement.

In connection with the closing of the final tranche, arms-length agents received an aggregate cash fee of $2,400. In addition, the Company issued to agents 24,000 broker warrants (the "Broker Warrants"). Each Broker Warrant will entitle the holder thereof to purchase one Common Share at an exercise price equal to $0.15 for a period of thirty-six months following the closing of the Placement.

In aggregate with the closing of the first and second tranche of the Placement, arms-length agents received a cash fee of $12,800. In addition, the Company issued to agents 128,000 Broker Warrants.

Proceeds from the Placement will be used to pay liabilities, accounts payable, and for general working capital. The securities issued pursuant to the final tranche of Placement are subject to a statutory hold period until August 16, 2021.

In aggregate with the closing of the first and second tranche of the Placement, certain insiders of the Company acquired 1,365,070 Units. This participation by insiders in the Placement constitute a "related party transaction" as defined under Multilateral Instrument 61-101 Protection of Minority Security Holders in Special Transactions ("MI 61-101"). However, the Company considers such participation would be exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 as neither the fair market value of the Units subscribed for by the insiders, nor the consideration for the Units paid by such insiders, exceeds 25% of the Company's market capitalization.
