Heron Commences Drilling Program at Currawang

Sydney, Australia, July 31, 2017 (GLOBE NEWSWIRE) -- Heron Resources Limited (ASX:HRR TSX:HER, “Heron” or the “Company”) is pleased to report a drilling program has commenced at its wholly owned Currawang prospect located 10km from the Company’s Woodlawn Zinc-Copper Project in New South Wales, Australia.

• Diamond drill program commenced at the Currawang Prospect
• 2,150m planned in four holes testing down-plunge and along strike extensions to known mineralisation
• Potential for the discovery of a satellite high-grade volcanogenic massive sulphide "VMS" deposit, 10km from the Woodlawn site
• 50% of direct drilling costs funded by the NSW Government’s Cooperative Drilling Program

Currawang Prospect

The Currawang mine produced approximately 0.5Mt of high-grade polymetallic VMS ore from an underground operation in the early 1990s that was processed at Woodlawn.  The attraction of Currawang is its potential to provide an additional high grade production source to supplement Woodlawn underground.  The VMS ore at Currawang is similar to the high grade polymetallic ore at Woodlawn, however, is hosted by the overlying Currawang Basalt unit with the lenses forming as replacement bodies within a hydrothermally altered basaltic breccia unit.

A number of significant historical intercepts that occur outside the mining stopes have been identified, including:

• 1m @ 17% ZnEq^[1] (9.0% Zn, 0.9% Cu, 4.3% Pb, 54g/t Ag), CU054^[2]
• 6m @ 16% ZnEq (8.8% Zn, 0.8% Cu, 5.2% Pb, 34g/t Ag), CU056

These drill holes are in the northern part of the former mining areas and at the time of their drilling were not followed-up.  A detailed review of the underground geology and historical DHEM (down-hole electromagnetic) surveys has been undertaken and a drill hole program designed to test the down plunge extensions of these intercepts.

A DHEM anomaly will also be targeted below a narrow, but high grade massive sulphide intercept in the north of the area (Figures 2 and 3) as well as a deeper DHEM anomaly in the south.

The four proposed holes will provide coverage of some 500m of strike along and below the Currawang deposit and provide an important platform for DHEM surveys.

Combined with a high-powered DHEM survey, this program has the potential to identify new extensions to the Currawang mineralisation.  The initial program of four diamond drill holes for 2,150m has received a NSW Government New Frontiers Cooperative Drilling grant which provides for reimbursement of 50% of the direct drilling costs.

About Heron Resources Limited:

Heron’s primary focus is the development of its 100% owned, high grade Woodlawn Zinc-Copper Project located 250km southwest of Sydney, New South Wales, Australia.  In addition, the Company holds a significant high quality, gold and base metal tenement holding in central and eastern New South Wales.

^[1] ZnEq % used in this release refers to the calculated Zn equivalent grade based on the Zn, Cu, Pb, Au and Ag grades, the formula for which is provided at the end of this report.

Compliance Statement (JORC 2012 and NI43-101)

The technical information in this report relating to the exploration results is based on information compiled by Mr. David von Perger, who is a Member of the Australian Institute of Mining and Metallurgy (Chartered Professional – Geology). Mr. von Perger is a full time employee of Heron Resources Limited and has sufficient experience, which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the “Australasian Code for Reporting of Exploration Results and “qualified person” as this term is defined in Canadian National Instrument 43-101 (“NI 43-101”). Mr. von Perger has approved the scientific and technical disclosure in the news release.

Zinc equivalent calculation

The zinc equivalent ZnEq calculation takes into account, mining costs, milling costs, recoveries, payability (including transport and refining charges) and metal prices in generating a Zinc equivalent value for Au, Ag, Cu, Pb and Zn.  ZnEq = Zn%+Cu%*3.12+Pb%*0.81+*Au g/t*0.86+Ag g/t*0.03.  Metal prices used in the calculation are: Zn US$2,300/t, Pb US$ 2,050/t, Cu US$6,600/t, Au US$1,250/oz and Ag US$18/oz.  It is Heron’s view that all the metals within this formula are expected to be recovered and sold.
