Heron Announces June 2016 Quarterly Update on the High Grade Woodlawn Zinc-Copper Project

Sydney, Australia, July 29, 2016 (GLOBE NEWSWIRE) --

July 29, 2016 – Sydney, Australia – Heron Resources Ltd. (TSX: HER; ASX: HRR) ("Heron" or the "Company") announces its quarterly activities for the three months ended June 30, 2016. Details of the Company's results are contained in the filing “Heron Resources Limited Quarterly Report June 2016” which is available on SEDAR at www.sedar.com and the Company's website www.heronresources.com.au

June Quarter 2016 Highlights

  • Cash and Cash Equivalents – At June 30, 2016 Heron held A$22.8M in cash (including A$0.2M in bonds) and A$1.7M in investments
  • Commodity market - fundamentals continue to strengthen for zinc, with zinc prices hitting a 12 month high in July
  • Woodlawn Zinc-Copper Project:

Feasibility Study: on 29 June 2016 the Company announced the results of the Woodlawn Feasibility Study (FS). The complete NI 43-101 Technical Report in support of the FS study was published on Heron’s website and lodged on SEDAR www.sedar.com (TSX:HER) on 26 July 2016. The key outcomes of this study include:

Attractive project characteristics

  • Initial 9.3 year mine life based upon the combined underground and tailings Mineral Reserves (“Starter Case”)
  • Campaign processing rate of up to 1.0Mtpa from underground mining, and up to 1.5Mtpa from reclaiming tailings, processed through a standard single-sulphide flotation facility
  • Steady-state (2020-2023) annual Production Target of 40kt Zn, 10kt Cu, 12kt Pb, 900koz Ag and 4koz Au contained within zinc, copper, and lead concentrates
  • Project is totally contained upon granted Special Mining Lease SML20 – Woodlawn is fully ‘permitted’ and ‘mine ready’
  • Utilising existing local and regional infrastructure to achieve significant reductions in development costs
  • Close proximity to large service and employment centres (Sydney, Wollongong, Canberra, Goulburn)
  • Strong local community and regulator support
  • Inferred Mineral Resources defined in both the underground and tailings projects demonstrate excellent potential to extend mine life to more than 11.5 years

Mineral Resources & Mineral Reserves

  • Underground mine plan focused on the shallower areas of the deposit reflecting the success of the recent Preliminary Economic Assessment (PEA) & FS drilling programs. There is a high level of confidence based on historic data for extensions to this mineralisation both at-depth and along strike
  • Two separate production sources, mining from underground and reclaiming of tailings, provides operational flexibility and reduces risk
  • 20 years of historical operational data removes ‘greenfield’ unknowns

Robust economics

  • C1 costs of US$-0.05/lb zinc and C3 of US$0.34/lb expected to place Woodlawn firmly in the lower half of the cost curve
  • Attractive capital cost metrics based on annual metal Production Targets and Reserves-based mine life
  • Life extension case (PEA equivalent mine plan) shows excellent consistency with previously published PEA
  • Significant leverage to the price outlook for zinc, which comprises approximately 48% of total payable metal value

Expedited development and financing pathway to meet market opportunity

  • The Company has commenced a structured project funding process with the assistance of Azure Capital and is targeting finalisation in the later part of 2016
  • A number of optimisation opportunities that have the potential to further enhance the project outcomes were identified during the FS program. A number of these options will be pursued in parallel to the funding and include aspects such as equipment sourcing alternatives and additional shallow mineralised positions
  • Rapid development schedule of 15 months from commencement of construction until completion of wet commissioning
  • First production targeted early 2018 to meet projected favourable zinc market conditions

Phase III Exploration Drill Program Commenced

  • A step-out drill program commenced in early July, with the first hole (WNDD0105) intersecting 1.2m of polymetallic massive sulphides in a 4.5m zone of sulphidic mineralisation from 538m depth – assays are pending. Down hole electro-magentics (DHEM) is planned to delineate potential conductors prior to further drilling. This intercept confirms the extension of the B Lens horizon in this northerly direction, and lends support to the potential for further discovery.
  • A number of holes are also planned to test for, and in-fill, shallow mineralised positions which could add to the Mineral Reserves for the early years of the production schedule

Woodlawn Zinc-Copper Project

Heron’s primary development project is the high grade Woodlawn Zinc-Copper Project located 250km southwest of Sydney, New South Wales. The project consists of both a high grade underground and a large medium grade tailings resource. The development approach envisages the construction of a single 1.5Mtpa processing plant capable of treating material from both sources. Planned production will see the generation of three separate base metal concentrates (zinc, copper and lead) with associated precious metal credits. In addition, the project is very well supported by excellent infrastructure, an existing mining lease and state government development approvals.

Woodlawn is expected to become an important Australian near term zinc producer delivering concentrates into a market with strong supply and demand fundamentals underpinning a strong commodity price.

About Heron Resources

Heron is engaged in the exploration and development of base and precious metal deposits in Australia. In addition to the high grade Woodlawn Zinc-Copper Project, the Company holds a significant property holding in the Lachlan Fold Belt of New South Wales and the Kalgoorlie Nickel Project in Western Australia.
