Alkane is pleased to announce the intersection of further high-grade mineralisation at its Boda Prospect in Central New South Wales. Boda is a landmark porphyry gold-copper system, within the Northern Molong Porphyry Project, which the Alkane believes has the potential to be a large, tier one gold-copper project
Reverse Circulation (RC) drilling to test for shallow extensions to the high-grade breccia first identified by KSDD007, intersected significant gold and copper grades from surface with substantial assay results of:
|KSRC043||31m grading 2.94g/t Au, 0.97% Cu from surface|
|incl||9m grading 9.43g/t Au, 2.65% Cu from surface|
|KSRC042||14m grading 0.40g/t Au, 0.11% Cu from 74m|
|and||226m grading 0.35g/t Au, 0.15% Cu from 108m|
|incl||10m grading 0.72g/t Au, 0.40% Cu from 157m|
|also||9m grading 0.73g/t Au, 0.50% Cu from 290m|
Previously advised RC drill hole (KSRC038), which ended in mineralisation, was diamond core tailed (KSRC038D) to also test for up-dip and strike continuation of the high-grade breccia. The hole intersected a sulphide cemented breccia within a broad zone of gold-copper porphyry mineralisation with significant assay results of:
|KSRC038D||711m grading 0.36g/t Au, 0.10% Cu from 118m|
|incl||17m grading 0.92g/t Au, 0.03% Cu from 302m|
|also||12m grading 1.93g/t Au, 0.20% Cu from 341m|
|also||17m grading 0.91g/t Au, 0.43% Cu from 501m|
|also||1m grading 15.2g/t Au, 0.14% Cu from 756m|
A deep diamond core hole (KSDD034) with a wedge hole (KSDD034W2), tested down-dip of the high-grade breccia. KSDD034W2 intersected a possible feeder structure and conduit to the breccia with significant assay results of:
|KSDD034W2||604m grading 0.13g/t Au, 0.14% Cu from 1,146m|
|incl||61m grading 0.10g/t Au, 0.26% Cu from 1,147m|
|incl||8m grading 0.25g/t Au, 0.61% Cu from 1,157m|
|also||32m grading 0.25g/t Au, 0.20% Cu from 1,249m|
These recent drilling results indicate the high-grade sulphide cemented breccia at Boda has a vertical extension of at least 800 metres, strikes northwest and dips sub-vertically to steeply to the northeast. Ongoing drilling will continue to define its dimensions.
Results were also received from diamond core drill hole KSDD033, testing the southern extensions to the mineralisation at Boda Two. The drill hole defined a zone of extensive gold-copper porphyry mineralisation, with significant intercepts of:
|KSDD033||995m grading 0.19g/t Au, 0.12% Cu from 322m|
|incl||8m grading 1.14g/t Au, 0.30% Cu from 894m|
|also||14m grading 0.49g/t Au, 0.23% Cu from 968m|
|also||30m grading 0.39g/t Au, 0.20% Cu from 1052m|
|also||7m grading 0.55g/t Au, 0.38% Cu from 1243m|
|and||21m grading 0.36g/t Au, 0.11% Cu from 1517m|
Drilling continues at Boda, Boda Two, Boda Three and Kaiser-Duke utilising two diamond core rigs and one high-capacity RC rig onsite, testing extensions and adding definition to the identified mineralised systems.
Alkane Managing Director, Nic Earner, said, “The high-grade breccia zone at surface not only further emphasises the large vertical depth of the system, but also gives rise to considering open cut as a potential mining method at Boda.
“We’re continuing our exploration program across the Porphyry Project, and we are planning a further 60,000 metres of drilling over the coming financial year. This substantial exploration program is designed to continue defining the internal high-grade zones within the extensive lowgrade mineralised envelopes at Boda, Boda Two and Kaiser prospects, as well as testing the corridor between the Boda and Kaiser targets.
“The drilling will also help us to identify further targets to contribute to the geological and structural understanding of the 15km intrusive corridor that extends from Boda South to Finns Crossing.”
Alkane also operates the nearby Tomingley Gold Operations (‘TGO’) and is working towards its stated ambition of becoming Australia’s next multi-mine gold producer
