Zenith Minerals (ASX: ZNC) has recommenced drilling at its Split Rocks project in Western Australia to follow-up significant bedrock gold mineralisation identified in Zenith’s maiden 16-hole RC drilling programme completed in September – October 2019.
The initial drill programme of approximately 2000m successfully confirmed bedrock gold targets beneath the currently operating Dulcie Heap Leach Gold Operation (DHLGO) – held by a 3rd party*.
In addition, the company has reported that further 1m resample assay results from that initial drill programme have expanded two of the previously reported gold mineralised intervals in holes ZDRC022 and ZDRC017.
- RC drilling recommenced at the Split Rocks Project in WA to follow-up significant bedrock gold mineralisation identified in Zenith’s maiden drill program completed in late 2019 beneath the Dulcie Heap Leach Gold Operation (DHLGO);
- New 1m resample results have expanded two previously reported gold mineralised intervals:
- ZDRC022: 11m @ 2.08 g/t Au from 59m depth, incl. 6m @ 3.32 g/t Au and
- ZDRC017: 4m @ 2.05 g/t Au from 30 m depth,
- in addition to previously reported results;
- ZDRC020: 5m @ 3.23 g/t Au from 8m depth,
- ZDRC021: 5m @ 2.04 g/t Au from 34m depth incl. 2m @ 3.94 g/t Au,
- Gold mineralisation is open and untested along strike and down dip with evidence of multiple stacked lodes, and mapped historic underground shafts and stopes;
- Drilling is planned to be completed in January with assay results anticipated to be received in February 2020.
Historical exploration reports on the area of the DHLGO leases highlight that high-grade gold mineralisation is predominantly hosted by moderately west dipping BIF units. High-grade historic drill results include: 6.0m @ 16.91 g/t Au, 2.0m @ 32.73 g/t Au, 2.0m @ 16.5 g/t Au, 2.0m @ 15.40 g/t Au, 5.0m @ 4.73 g/t Au, 4.0m @ 4.90 g/t Au and 9.0m @ 2.20g/t Au, presenting several high-priority target zones for follow-up by Zenith.
Historic holes were drilled either vertical or at -600 east. Assuming moderate west dipping gold mineralisation then the intersection widths will be close to true widths, however there is insufficient drill density to be confident that all gold zones are dipping west and therefore caution must be applied regarding the widths of reported gold zones.
Most historic drill holes have only focused on the near surface laterite rich gold zone with the average drill hole depth for the project area only 19.7m (1,777 historic shallow holes).
