Zenith Minerals (ASX: ZNC) has released preliminary assay results from 4-metre composite sampling of 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.
· A 16-hole initial RC drilling program completed to test bedrock gold targets at Split Rocks;
· Gold mineralisation (>0.5 g/t Au) intersected in 12 of 16 holes completed, with preliminary 4-metre composite sampling returning several strong intersections for resampling including:
· 12m @ 1.97 g/t Au from 60m including 8m @ 2.72 g/t Au in ZDRC022 (abandoned before ultimate target depth due to water),
· 8m @ 1.41 g/t Au from 8m plus 4m @ 1.66 g/t Au from 44m in ZDRC020,
· 8m @ 1.08 g/t Au from 32m plus 8m @ 0.69 g/t Au from 72m in ZDRC021,
· 12m @ 0.71 g/t Au (EOH) from 20m in ZDRC011, and
· 10m @ 0.57 g/t Au (EOH-abandoned in old underground workings) from 32m in ZDRC017.
· One metre resamples for mineralised intersections have been submitted for assay with results anticipated in around 2 – 3 weeks;
· 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 on receipt of one metre resample results; 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 21 st March 2019 that it had executed 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 (Figures 2 & 3). 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).
