Extensional drilling in 2019 has increased the plunge by more than 100% and the northern-most drilling shows shallow mineralisation is thicker and continues to deliver consistent high grades along strike.
These results lie within a sub-audio magnetic (SAM) target and highlight the potential for other similar targets in the Myhree Boundary Corridor.
SAM targets 1 and 2 were also drilled during April 2019 with results pending.
Black Cat managing director Gareth Solly said: “The potential for Myhree to become a near-term open pit is improving with Myhree already a robust, high-grade near-surface resource located on a mining lease and only 30 kilometres from Kalgoorlie.
“The extensional drilling shows that thickness and grade continue at depth with the northern-most line of drilling intersecting the best results from Myhree to date, with thick high-grade mineralisation in shallow positions.
“The challenge now is to determine just how big Myhree is and we are looking to fast-track the next round of RC drilling to mid-May 2019 with an updated resource at Myhree to be released in July 2019.”
High-grade results include:
- 28 metres at 5.06 g/t from 4 metres, including 9 metres at 6.64 g/t from 4 metres and 10 metres at 7.55 g/t from 20 metres;
- 10 metres at 4.24 g/t from 77 metres;
- 6 metres at 4.67 g/t from 82 metres;
- 3 metres at 4.13 g/t from 121 metres; and
- 1 metre at 13.9 g/t from 213 metres.
Myhree remains open towards Boundary to the north, now only 640 metres away.
Infill drilling to upgrade the resource to indicated has also begun. Results are consistent with previous results and include:
- 3 metres at 7.89 g/t from 16 metres; and
- 3 metres at 7.06 g/t from 37 metres.

Infill drilling will continue during the next drilling campaign and an updated resource at Myhree is expected to be released in July 2019.
