Greencastle Renews Normal Course Issuer Bid and Cancels 1,377,500 Shares

TORONTO, ONTARIO--(Marketwired - Aug. 8, 2017) - Greencastle Resources Ltd. (TSX VENTURE:VGN) (the "Company") wishes to announce that, subject to regulatory approval, it will conduct a normal course issuer bid (the "Bid"). The Bid will be for up to 3,499,272 common shares of the Company over a period of one year (the "Bid Period"), being approximately 8.4% of Company's issued and outstanding common shares and being 10% of the Public Float (as that term is defined in the policies of the TSX Venture Exchange ("TSXV")) of the Company's issued and outstanding common shares, with up to 828,423 common shares of the Company purchasable over any 30-day period within the Bid Period, being 2% of Company's issued and outstanding common shares. The Bid Period will commence on August 11^th, 2017, and will continue until the earlier of August 10^th, 2018, or the date by which the Company has acquired the maximum 3,499,272 common shares which may be purchased under the Bid.

During the period between March 30^th, 2016, and March 29^th, 2017, the Company completed the purchase and cancellation of 1,377,500 common shares under its previous normal course issuer bid at a volume weighted average price of $0.12 per share.

Management believes that the market price of the Company's common shares may not fully reflect the value of its business and future prospects, and as such it believes that purchasing its own common shares for cancellation is an appropriate strategy for increasing long-term shareholder value. The purchases will be made through the facilities of the TSXV, and the price at which the Company will purchase its common shares will be the market price of the shares at the time of acquisition. The Company has appointed Canaccord Genuity Wealth Management as its broker to conduct normal course issuer bid transactions.

The Company has 41,421,171 common shares issued and outstanding. Common shares purchased by the Company will be returned to treasury for cancellation.
