Woodlawn Drilling Update – High Grade Results from new Lisa Lens
Heron Resources Ltd. (“Heron” or the “Company”) is pleased to report a significant intercept of high-grade massive sulphide grading approximately 18% Zn from the discovery hole drilled into the Lisa Lens.
These results form part of the highly successful 2014-15 drilling program that will delineate new Mineral Resources to contribute to the on-going Preliminary Economic Assessment (PEA) for the planned Woodlawn Underground Project.
The Phase I drill campaign has concluded with step-out holes being drilled to the north of the Kate Lens and directly to the south of the historic open-pit mine.
Woodlawn is a high-grade, volcanogenic massive-sulphide (VMS) deposit, wholly-owned by Heron and located approximately 50km northeast of Canberra and 250km southwest of Sydney, in New South Wales, Australia.
Assay Results
Assay results for diamond drill hole (DDH) WNDD0015 confirm 18.3m of pyrite dominant massive-sulphides containing a significant polymetallic intercept of:
4.2m @ 17.7% Zn, 1.6% Cu, 5.0% Pb, 1.1g/t Au, 28g/t Ag from a depth of 246m
DDH WNDD0015 targeted a position directly to the north of two historic drill holes, W089 and W145, in an area postulated to contain an additional lens of mineralisation (Figure 1). The results of the historic holes include:
4.0m @ 4.9% Zn, 2.8% Cu, 2.3% Pb, 0.8g/t Au and 25g/t Ag from a 266m depth (W089)
4.0m @ 2.0% Cu from a 234m depth (W145)
The result in WNDD0015 is highly encouraging and demonstrates the potential for Woodlawn to host relatively shallow high-grade mineralisation analogous to that historically encountered in the idled underground.
Neighbouring DDH WNDD0017 targeted the predicted up-plunge direction of the new lens as follow-up to WNDD0015, however a late-stage dolerite intrusive body has displaced the target. DDH WNDD0017 was continued and intersected the D Lens, where an interval of 9.5m of massive sulphides was intersected (assays pending).
DHEM Surveys
Down-hole electro-magnetic (DHEM) surveying of WNDD0015 has been completed and preliminary modelling indicates good potential for extensions of the mineralisation both down-dip and along strike to the north and south. At this stage modelling suggests the centroid of the lens is positioned below the DDH WNDD0015 intercept, and explains the lack of mineralisation found in DDH WNDD0017 which penetrated the up-dip position. As shown in Figure 1, the modelled lens “plate” is smaller than the Kate Lens, but the excellent grade returned from WNDD0015 supports follow-up drilling. Lisa Lens is located within 100m of existing underground development.

Drilling Program Update
Phase I drilling at Woodlawn has now concluded. In addition to DDH WND 0015, DDH WNDD0018 tested the postulated northerly extension of the Kate Lens, and WNDD0020 was drilled to test at depth below the southern end of the Woodlawn pit where historic Jododex hole W024 intersected 15.7m grading 8.7% Zn, 0.9% Cu, 2.6% Pb, 1.0g/t Au and 71g/t Ag. There is limited follow up drilling in this area. The key results for these two holes are as follows:
- WNDD0018 intersected 2.2m of semi-massive sulphides, with minor base-metal sulphides from a 370m down-hole depth, indicating a potential position proximal to the limit of the Kate Lens mineralisation in the northern direction towards D Lens.
- WNDD0020 intersected a number of zones containing VMS-related moderate to intense sericite, quartz, pyrite alteration within the Woodlawn Volcanics, including a number of narrow (>1m) zones of remobilized zinc mineralisation (sphalerite) in quartz veins.
DHEM is planned for both these holes to identify potential off-hole conductors.
The results from the drilling program support Mineral Resource modelling, providing a key input into the Preliminary Economic Assessment due to be released in the first-half of 2015.
Full details of all holes drilled and assay results to date are provided in Tables 1 and 2 at the end of this report. The total diamond metres for the first phase program was 7,613m in 20 holes. In addition, some 770m of diamond drilling in 11 holes was undertaken for geotechnical assessment of the decline access route, which has now also been finalized.

Notes: True width is an estimate of the actual thickness of the intercept based on interpreted lens orientation (approximately 80% of downhole width); grades are weighted average grades, weighted by length of samples intervals downhole, which are nominally 1 metre. No weighting was applied for differences in specific gravity. * Previously reported results.
