The package comprises a loan, equity and stream funding package from subsidiaries of Orion Mine Finance Group ("Orion") for a total of A$129 million⁽³⁾, an equity subscription agreement with a subsidiary of existing shareholder Greenstone Resources LP ("Greenstone") and co-investment parties for A$42 million⁽³⁾, an equity subscription agreement from new cornerstone equity investor, Castlelake, L.P. ("Castlelake") for A$33 million⁽³⁾ (together, the "Cornerstone Investors"), and the receipt of commitments from various sophisticated and professional investors to subscribe for fully paid ordinary shares in the Company ("Shares") to raise approximately A$32 million ("Institutional Placement").

The issue price for all new shares under the total funding package was A$0.07 per share, and represents a 14% discount to the volume weighted average price of Heron shares traded on the ASX during the 10 days up to and including 26 June 2017.

A summary of the key terms of the Institutional Placement and the arrangements with the Cornerstone Investors, including the conditions precedent attaching to each of these commitments, is set out in the Annexures to this announcement.

Heron is also offering eligible existing shareholders the opportunity to participate in a Share Purchase Plan ("SPP") to raise up to a further A$5 million at the same price as the Institutional Placement and the equity component of the funding package with Cornerstone Investors ("Cornerstone Investor Placement").

Commenting on the funding package, Heron's Managing Director, Wayne Taylor said:

"We are pleased to have delivered a complete funding package that will enable the timely development of Woodlawn. Our operations team and our EPC lead contractor, Sedgman, are ready to commence construction of the Project immediately upon securing shareholder approval for the transaction, with the aim of commissioning Woodlawn in late 2018 and entering an increasingly supply constrained zinc market.

"We welcome Orion to the Company's share register and their nominee Director, Peter Rozenauers, to the Board. We also welcome Castlelake as a new major shareholder, and their nominee Director, Ricardo De Armas, to the Board. And we acknowledge the strong and continued support of our major shareholder, Greenstone, for their ongoing and increasing commitment to the Company's vision at Woodlawn.

"The backing of the major equity investors Greenstone and Castlelake provides a very strong endorsement of the potential for our Project. With their commitment and the support of major funder Orion, we look forward to progressing Woodlawn into production in 2018 and developing Heron into a substantial base metals company in the future."

The delivery of this complete funding package follows a number of key approvals and work programs that will allow for immediate commencement of construction works following completion of the Institutional Placement and the Cornerstone Investor Placement, including:

• Execution of the engineering, procurement and construction contract with Sedgman Pty Limited to be undertaken at a guaranteed maximum price of A$107 million (announced 4 May 2017)
• Execution of off-take agreements for all three concentrates with Louis Dreyfus Metals (announced 10 May 2017)

Equity Funding

Equity Investment Structure

The Cornerstone Investor Placement will be undertaken in two tranches:

• The first tranche will consist of approximately 104 million shares, with approximately 30 million shares allocated to Greenstone, approximately 28 million shares to Orion, and approximately 46 million shares to Castlelake.
• The second tranche will consist of approximately 1,372 million shares, with approximately 571 million shares allocated to Greenstone and its co-investment parties, approximately 380 million shares to Orion, and approximately 421 million shares to Castlelake.

The issue of Shares to Castlelake under the first tranche is scheduled to settle on or about Tuesday, 4 July 2017. The issue of Shares to Greenstone and Orion under the first tranche will occur contemporaneously with completion of the second tranche unless either Greenstone and/or Orion elect to be issued their respective Shares under the first tranche earlier.

The second tranche is scheduled to settle on the same day as completion of the Institutional Placement.

Completion of the Institutional Placement and the second tranche of the Cornerstone Investor Placement is subject to a number of conditions precedent, including the approval of Heron's shareholders at a general meeting to be held in August 2017. Heron expects to release in the coming weeks a Notice of Meeting containing detailed information about the funding package, which will also include an Independent Expert's Report. For a summary of the key terms of the Institutional Placement and the Cornerstone Investor Placement, please refer to Annexures 1 to 5 to this announcement.

Share Purchase Plan

Heron intends to undertake a SPP to allow for the participation of eligible shareholders for an amount up to A$15,000 per shareholder, at a price of A$0.07 per share (the offer price under the Institutional Placement and the Cornerstone Investor Placement). The SPP will raise up to A$5 million. An eligible shareholder is any shareholder recorded on Heron's share register at 5:00pm AEST on Thursday, 29 June 2017 with a registered address in Australia or New Zealand. Shareholder approval is not required for the SPP.

Heron reserves the right to close the SPP early and scale back applications at its absolute and sole discretion should the total demand exceed A$5 million. When determining the amount (if any) by which to scale back an SPP application, Heron may consider a number of factors, including the size of an applicant's shareholding in the Company, the extent to which an applicant has sold or bought additional shares in the Company after the SPP record date, and the date on which an application was made with earlier applications given precedence.

Eligible Shareholders will receive further information in relation to the SPP shortly.

Canadian disclosure	Greenstone is a holder of in excess of 10% or more of the issued and outstanding shares of the Company, holding 54,131,658 shares representing 13.0% of the issued and outstanding shares. As result, Greenstone is an "insider" of the Company and the participation in the Cornerstone Investor Placement by Greenstone constitutes a "related party transaction" as such terms are defined by Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101") adopted by certain Canadian Securities Administrators. In accordance with MI 61-101, the Company is required, in the absence of exemptions, to obtain a formal valuation for, and minority shareholder approval of, the "related party transaction". In the case of the first tranche of the Cornerstone Investor Placement, the Company is relying on the exemptions from the formal valuation and minority approval requirements of MI 61-101 pursuant to which a formal valuation and minority approval are not required in the event that at the time the Cornerstone Investor Placement is agreed to, neither the fair market value of the subject matter of, nor the fair market value of the consideration for, the transaction, insofar as it involves Greenstone, exceeds 25 per cent of the aggregate amount of the shares outstanding upon completion of each tranche of the Cornerstone Investor Placement and the other financings. In the case of the second tranche of the Cornerstone Investor Placement, no exemptions are required from MI 61-101 as minority approval will be obtained and an "Independent Expert's Report" will be provided to shareholders which satisfies the requirement of a formal valuation under MI 61-101. Greenstone has agreed to acquire a total of 398,496,241 shares in the Cornerstone Investor Placement for gross proceeds of A$27,894,737. Greenstone will own 452,627,899 shares representing 18.7% of the issued and outstanding shares after completion of the Cornerstone Investor Placement and the other financings. The participation in the private placement by Greenstone was approved by directors of the Company who are independent of that related party. Mr. Mark Sawyer is the nominated representative of Greenstone on the Board and he abstained from approval of this matter. The first tranche of the Cornerstone Investor Placement is expected to be completed in less than 21 days from the date of this announcement in order to provide immediate funding to the Company.
