Estrella Resources (ASX: ESR) has intersected two ‘broad’ zones of massive and semi-massive nickel-copper sulphides below its Carr Boyd nickel mine during its latest round of diamond drilling.
Standout results from hole CBDD064 include:
- Main Zone – 16.96m massive and semi-massive Ni-Cu-S from 193.9m
- Mid Zone – 1.32m semi-massive to matrix Ni-Cu-S from 242.9m
- Lower Zone – 12.91 semi-massive, matrix and disseminated Ni-Cu-S from 256.1m
The intersection is interpreted by the company as confirming the continuation of nickel-copper sulphides below old workings, and coincides with a downhole electromagnetic (DHEM) response modelled from the top section of hole CBDD056A, drilled in October 2021.
“While our focus is very much on drilling, we are also highly focused on determining the Carr Boyd sulphide’s relationship to the T5 mineralisation found on the Basal Contact”
Addressing the results, Estrella Resources Managing Director Chris Daws said: “I am highly encouraged by these latest rounds of results from CBDD064 as it confirms massive sulphide mineralisation continues below the old Carr Boyd workings.
While our focus is very much on drilling, we are also highly focused on determining the Carr Boyd sulphide’s relationship to the T5 mineralisation found on the Basal Contact.
Through our ongoing work with the CSIRO, which includes logging and geochemical analysis, we are highly confident on determining this link which, if it exists, means a very exciting time ahead for investors as it is proof this large pool of sulphides may still exist at depth.”
Estrella notes that current work is focused on determining the link between the Carr Boyd sulphide’s relationship to the T5 mineralisation found on the Carr Boyd basal contact 1km away to the northwest.
Diamond hole CBDD064 in relation to historical Carr Boyd mine workings and T5 basal contactIf proven, Estrella believes that there is an opportunity that this large pool of sulphides still exists at depth.
Assistance with logging and geochemical analysis is being provided by the CSIRO, and hole CBDD064 was targeted across dip to provide optimal data for this work.
