Hillgrove Resources Limited (ASX:HGO) has provided underground drilling updates from its Kanmantoo copper mine in South Australia, with the final nine holes of a 37-hole program delivering a 166m copper intercept.
Highlights include:
- Hole KTDD208: 166.3m @ 0.9% Cu, 0.13 g/t Au from 332m, including:
- 30.25m @ 1.32% Cu, 0.08 g/t Au from 332m, and
- 106.3m @ 0.95% Cu, 0.17 g/t Au from 392.0m, including:
- 9.0m @ 2.19% Cu, 0.17 g/t Au from 332m,
- 8.25m @ 2.16% Cu, 0.07 g/t Au from 354m,
- 29.55m @ 1.39% Cu, 0.46 g/t Au from 392m,
- 10.0m @ 2.16% Cu, 0.11 g/t Au from 443m,
- 17.7m @ 1.55% Cu, 0.09 g/t Au from 468m
- Hole KTDD203_W5: 7.1m @ 0.53% Cu, 2.3 g/t Au from 790.6m including:
- 3.0m @ 1.11% Cu, 5.02 g/t Au from 794m
“drilling results continue to demonstrate the opportunities for growing the underground resource at Kanmantoo”
Drilling expands footprint at Kanmantoo
Hillgrove reports that drilling during the June-August period has continued to expand the Cu-Au mineralised footprint at Kanmantoo, with hole KTDD208 extending the wide zone of Cu-Au intersections previously reported in May. The beginning of the wide zone encountered by hole KTDD208 sits ~70m south of the 170m-wide Cu mineralisation previously reported in hole KTDD205.
Additional drill holes at adjacent Spitfire and South-West Kavanagh systems have encountered further mineralisation including:
- Hole KTDD206_W2: 7.5m @ 1.87% Cu, 0.08 g/t Au from 328.5m
- Hole KTDD206_W4: 4.6m @ 3.71 g/t Au from 410m, including:
- 2.0m @ 8.26 g/t Au
The company reports that every hole drilled since its previous June update has encountered Cu-Au mineralisation, further strengthening underground opportunity at the project.
Management comments
Hillgrove Resources CEO and Managing Director Lachlan Wallace said: “The multiple high-grade Cu-Au intersections in hole KTDD208 which aggregate to over 166m at 0.9% Cu and 0.13 g/t Au are an exciting confirmation of the large volume of mineralisation intersected in the earlier KTDD205 drill hole. This is a major breakthrough in the scale of the possible underground opportunity and justifies the continued drilling to better define the mineralised zones and their Cu-Au endowment. Overall, the drilling results continue to demonstrate the opportunities for growing the underground resource at Kanmantoo and are an exciting development which, coupled with the rising copper price, provide opportunities to expand the potential mining inventory and optimise the existing plant and tailings storage capacity at the Kanmantoo site.”
