  • Diamond core drilling: 17 holes for 3,225m targeting the G2 and Lisa Lens positions completed
  • G2 Lens: (14 holes for 2,411m) extension and definition program completed with significant results to date of:
  • 6.1m grading 37.2% ZnEq from 120.3m (22.0% Zn, 1.0% Cu, 7.1% Pb, 3.3g/t Au, 115g/t Ag) WNDD0138 G2HW
  • 1.9m grading 8.2% ZnEq from 138.3m (4.1% Zn, 0.3% Cu, 2.2% Pb, 0.5g/t Au, 27g/t Ag) WNDD0138 G2 Main

Peelwood: Electromagnetic anomalies (2014 airborne survey) potentially related to base metal mineralisation defined north of the John Fardy and Cordillera prospects provide walk-up drill targets, with drill approvals currently being progressed


  • Cash: Heron held A$74.3 million in cash (including bonds of A$8.77 million) and A$7.9 million in investments as at 30 June 2018
  • Debt: US$20 million senior secured facility was drawn down during the June quarter. US$40 million senior secured facility remains undrawn
