Zenith Minerals (ASX: ZNC) has reported final 1m assay results from a 16-hole RC drilling program at its Split Rocks project in Western Australia. This initial program of approximately 2000m successfully confirmed bedrock gold targets beneath the currently operating Dulcie Heap Leach Gold Project (DHLGO) – held by a 3rd party.
· Initial RC drilling program returned significant bedrock gold mineralisation at Split Rocks, with gold mineralisation (>0.5 g/t Au) intersected in 12 of 16 wide spaced drill holes;
· Final 1m resample results confirm and upgrade the initial preliminary 4-metre composite sampling results, previously reported to ASX on 21 October 2019.
· New 1m-results from 3 separate drill areas over 2.6km of strike, include:
· 10m @ 2.20 g/t Au from 60m including 6m @ 3.32 g/t Au in ZDRC022 (abandoned before ultimate target depth due to water),
· 5m @ 3.23 g/t Au from 8m plus 4m @ 1.48 g/t Au from 44m and 1m @ 3.79 g/t Au from 124m in ZDRC020,
· 5m @ 2.04 g/t Au from 34m incl 2m @ 3.94 g/t Au plus 2m @ 0.89 g/t Au from 75m in ZDRC021, and
· 2m @ 2.56 g/t Au from 32m and 3m @ 0.57 g/t Au from 38m (hole abandoned in old underground workings) in ZDRC017.
· Although several holes were abandoned prematurely due to historic workings and water, the drill program has successfully confirmed the presence of significant bedrock gold mineralisation below the widespread gold in surface laterite. A follow-up drill program will be designed shortly; and
· Dual purpose program provided an initial wide spaced drill test of bedrock gold targets and lithium pegmatite bodies identified in the historical drilling in this highly prospective Forrestania lithium belt.
Zenith announced on the 21st March 2019 an option agreement with the owners of the DHLGO whereby the Company has an exclusive right to explore for bedrock gold mineralisation beneath the large laterite rich gold cap currently being mined and treated on leases located contiguous with Zenith’s Split Rocks project licences, located in the Forrestania greenstone belt, Western Australia.
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.
Highgrade 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.
