Heron Commences Drilling Program at Currawang
- 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 VMS deposit, 10km from the Woodlawn site
- 50% of direct drilling costs funded by the NSW Government’s Cooperative Drilling Program
Heron Resources Limited has reported 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.
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:
- 10.1m @ 17% ZnEq
- (9.0% Zn, 0.9% Cu, 4.3% Pb, 54g/t Ag), CU054
- 8.6m @ 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
ADHEM 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.
Further updates on drilling progress at Currawang will be provided as results become available.
