Heron Resources Limited Woodlawn Drilling Commences

Heron Resources Ltd. (“Heron” or the “Company”) is pleased to announce the commencement of the 2014 drilling program at the high grade Woodlawn Project, located in New South Wales, Australia.


Highlights:

- Significant four month drilling program underway

- 7,200m diamond and up to 5,000m RC drilling

- Targeting resource expansion, geotechnical data and metallurgical sample material

As noted in the 27 August 2014 market release, Heron has committed to undertaking a significant drilling program at the Woodlawn Project and now confirms that the first diamond drill rig has commenced on site. The second drill rig, being an RC rig, is being mobilized and expected to commence within the next few days.


014 Woodlawn Drilling Program

The Woodlawn VMS system comprises 12 known massive sulphide lenses and these are the focus of the current drilling program. The target is to delineate additional resources up and down dip in support of recommencing underground mining at Woodlawn, including the testing of the new Kate Lens, discovered in 2013.  

The drilling program consists of up to 5,000 metres of shallow RC drilling, and 7,200 metres of diamond drilling and separated into four major components:

1. Shallow RC drilling to test the up-dip extension to known lenses

2. Mid-depth diamond drilling targeting Kate Lens and other western lenses

3. Limited deep drilling targeting I, I2, D and B Lenses

4. Geotechnical drilling for the box cut and access decline

The RC drilling will target the up-dip extensions to a number of the lenses that historically lacked access and were impeded by existing mine infrastructure that was constructed prior to their discovery. With modifications to the mine layout these areas now have the potential to provide Heron with the early stage, easy access sources of high grade underground feed stock to the future processing plant.

The mid-depth drilling is centered on 350 to 400 metres below surface and well above the base of the former operations. Within this zone a key target is the Kate Lens (up/down dip and along strike from the discovery hole). In addition, there are a number of holes testing the down plunge extensions to a number of the lenses that were not extensively exploited historically. These areas also have the capacity to deliver easy access ore to the mine production early in the mine life.

The deeper drilling is designed to test the I, I2 and D lenses at depths down to 450 metres below the surface before continuing down to test extensions of the thick (often over 20 metres during previous underground mining) and high-grade B Lens position at some 750 metres to 800 metres below the surface.

An integral part of the program will be the further use of downhole EM surveying, the technique responsible for the discovery of the Kate Lens. The EM loops are being designed to fit around the existing surface infrastructure and it is expected that they can be left in place to enable rapid turnaround of results to assist with concurrent hole planning.

Geotechnical logging of the core will provide critical input data for the selection of appropriate mining methods to be applied to individual areas. This drilling program will also provide material for metallurgical testwork to commence on the Woodlawn Underground Project. Additionally, sterilization RC drilling is required in the area of the box cut and proposed plant site area. The final component to the program is the geotechnical drilling to finalise the access box cut location and design parameters.


Woodlawn Near-Mine Exploration

The current drill program has clearly defined targets, however, in the area immediately adjacent to the mine site are a number of priority areas that will form the initial step-out exploration at Woodlawn. The top priority is the structurally controlled northwest corridor (Figure 2) which forms a logical extension to the current exploration work.

The massive sulphide lenses discovered to date at Woodlawn are stacked and structurally bound by northwest trending faults. This area remains untested outside of the immediately defined mineralized footprint due to existing surface infrastructure previously inhibiting the establishment of suitable drilling locations. In addition, this structural corridor is further supported by defined EM anomalies from previous survey work. These anomalies are currently being reviewed by the Company’s geophysical consultants and will be one of numerous data-sets used to generate future targets.

Woodlawn Regional Exploration

The regional exploration setting is considered very prospective for further base metal discovery. This has been demonstrated through the previous mining operations at Cowley Hills, 2km north of Woodlawn, and Currawang, 9km northwest of Woodlawn (Figure 3). These deposits provided high grade base metal satellite feed to the Woodlawn concentrator during the former operations.

Currawang is of particular interest having produced in excess of 500,000 tonnes of ore from an underground mine between 1991 and 1995.  This ore was trucked the 10km southeast to Woodlawn and was of similar grade to the Woodlawn ore. The deposit is largely hosted by the Currawang Basalt in a higher stratigraphic position than Woodlawn. Two high priority targets have been generated in this area through a detailed review of the project in 2009.  The ore lenses at Currawang were often rich in pyrrhotite making them potential EM targets and therefore, the priority targets will be surveyed with surface EM prior to potential drill testing.
