Perth-based Bardoc Gold Limited (ASX: BDC) has reported further results from ongoing diamond drilling at the cornerstone Zoroastrian deposit within its namesake Bardoc Gold Project near Kalgoorlie in WA, indicating potential to grow inventory and mine-life.
Multi-lode system at Zoroastrian extends at depth
The company’s ongoing drilling at Zoroastrian is aimed at extending mineralisation at depth and along strike, while increasing confidence in material outside of current reserves.
“These results support our view that there is immense potential to grow the inventory and mine life at Zoroastrian”
Bardoc’s extensional drilling has now confirmed that mineralisation extends for more than 150m below the existing resource at both the Blueys South and Zoroastrian South lodes, which form the basis of the current Zoroastrian underground ore reserves of 98,000oz @ 3.6g/t, with 530,000oz @ 2.2g/t in the indicated and inferred mineral resource categories.
The drilling also extended the known mineralisation along strike at the Blueys and Royal Mint lodes.
These latest extensional drilling results include a number of key strikes:
- Hole KND210001: 6m @ 2.44g/t Au from 460m
- Hole KND210003: 1m @ 11.7g/t Au from 466m
- Hole KND210007: 4.5m @ 3.53g/t Au from 102m
Bardoc Chief Executive Robert Ryan said: “These results support our view that there is immense potential to grow the inventory and mine life at Zoroastrian through extensions to the known mineralization at depth and in new areas.
The diamond drilling program we commenced in August has already confirmed the presence of mineralisation 150m below the current Resource envelope, providing strong evidence for what we have long suspected – that the multi-lode system at Zoroastrian extends at depth.”
Higher-than-expected grades from infill drilling
The company reports that resource definition drilling returned grades which exceeded those in the resource model, highlighting the potential for increases in the Zoroastrian ore reserve. Results included:
- Hole KND210007: 5.2m @ 4.97 g/t Au from 379m; including
- 1.69m @ 14.1 g/t Au from 381.62m
Importantly, the resource definition program has targeted mineralisation sitting in the inferred category, with drilling potentially providing confidence to upgrade the mineralisation to indicated status, and thus included in ore reserves.
Moving ahead to updated MRE
After completion of the current drilling program by late 2021, Bardoc expects to complete an updated mineral resource model in early 2022.
This upgraded area may include additional indicated material as well as depth extensions to the known resource, leading to increased ore reserves and mine life.
The company also reports that the drilling program has deployed an extra drill shift to ensure the timely completion of the program.
