ST PETER PORT, GUERNSEY--(Marketwired - Aug. 20, 2015) - Greenstone Resources L.P. is pleased to announce that its affiliate, Greenstone Management (Delaware) LLC, acting in its capacity as general partner of Greenstone HRR Holdings LP ("Greenstone"), has completed its stage 1 AUS$6.8million investment in Heron Resources Limited ("Heron" or "the Company") announced to the market on 24 July 2015 (the "Placement").

The Placement was priced at AUS$0.126 per share (approximately C$0.122 based on an exchange rate of C$0.9668:AUS$1.00, the Bank of Canada noon rate as of 17 August, 2015) and represents a premium to the trading price of Heron equities at the time the transaction was announced.

Pursuant to the Placement, Greenstone acquired ownership and control of 54,131,658 ordinary shares (the "Shares"), representing 13.04% of the issued and outstanding ordinary shares of the Company. The Placement has been made within the Company's 15% placement capacity pursuant to ASX Listing Rule 7.1. Greenstone is now Heron's largest shareholder with a 13.04% interest. As noted in Heron's release on July 24, 2015, the agreed arrangements also envisage a potential additional investment by Greenstone of AUS$13.2 million (or such amount as would take Greenstone's interest to up to 19.9% of Heron shares) as a contribution towards the equity funding component of the staged construction of the Company's Woodlawn Zinc-Copper Project ("Woodlawn Project") located in New South Wales, Australia. Any such additional funding is subject to the Company making a decision to proceed with the staged development of the Woodlawn Project, and with Greenstone being satisfied with the proposed terms of any such fundraising.
