Prior to this drilling program the mineral resource modelled in the area was not sufficient grade to be included in the ore reserve and mine plan due to wider spaced drilling in the deeper zones of this area.
Recent drilling has targeted these high-grade areas, as knowledge of the ore system's plunge-and-dip characteristics have been better defined by mine development.

Pantoro’s managing director Paul Cmrlec said these new outstanding results, combined with the recent high-grade intersections in the Anderson lode to the north of the mine, confirm the continuing high-grade nature of the Nicolsons ore system at depth.
Cmrlec said: “The results will be included in the annual mineral resource and ore reserve update to be completed at June 30, 2019 and will contribute to the ongoing growth of the mine.
“Operations in the Wagtail North underground mine continues to access new ore development faces in the Wagtail and Rowdies ore bodies and the Wagtail South open pit cutback is progressing to plan.
“With ore production increasing from both of the Wagtail mining areas and Nicolsons mine operating in steady state the Halls Creek Operations are in strong position to meet the planned 80,000 ounces per annum production rate by the middle of this year.”
New results include:
2.45 metres at 73.09 g/t gold, including 0.6 metres at 289.7 g/t;
2.95 metres at 51.47 g/t;
1.9 metres at 35.89 g/t;
1.7 metres at 11.6 g/t;
2.20 metres at 16.85 g/t; and
0.8 metres at 43.63 g/t.
The results demonstrate the continuity of mineralisation at depth in the Johnston Lode and follow the recent drill program completed in the Anderson Lode in the northern end of the mine.
