| ABSTRACT: | Heron Resources Limited (ASX:HRR, “Heron” or the “Company”) is pleased to report the June 2019 Mineral Resource and Ore Reserve estimates at its wholly-owned Woodlawn Zinc-Copper Project, located 250km south-west of Sydney, New South Wales, Australia (Figure 1). The estimates incorporate recent drilling in the G2 Lens area and some modifications to estimation parameters; however neither the Mineral Resource or Ore Reserve have materially changed since previous reports. The underground Woodlawn Volcanogenic Massive Sulphide (VMS) mineralisation is hosted in Late Silurian deep water marine mudstones and volcaniclastic debris flows associated with a rhyolitic volcanic centre within the Goulburn Basin. The Woodlawn deposit comprises 12 known sulphide lenses (Figure 2) which form three mineralised horizons locally disrupted by faulting. The Zinc, Copper and Lead (Zn, Cu and Pb, respectively) mineralisation occurs as massive and stringer sulphide lenses, interpreted to have formed both on the sea floor and as replacement mineralisation developed within coeval mudstones and volcanic breccia flows. The mineralisation is derived from hydrothermal fluids which emanated from the adjacent rhyolitic volcanic centre and is associated with an aerially extensive, zoned alteration envelope. The Mineral Resource at Woodlawn is defined by both historic and more recent Heron diamond drilling, as well as underground mapping from prior operators. | |
