Estrella Resources ASX ESR intersects massive nickel copper sulphides under Carr Boyd mine
Estrella Resources is working to determine the relationship between the Carr Boyd sulphide mineralisation and the T5 discovery.

Diversified explorer Estrella Resources (ASX: ESR) has announced the intersection of two broad zones of massive and semi-massive nickel-copper sulphides below the Carr Boyd nickel mine in Western Australia.

The mineralisation was intersected in a diamond drillhole and includes a 16.96m main zone of massive and semi-massive nickel-copper sulphide from 193.9m, a 1.32m mid zone of semi-massive to matrix sulphide from 242.9m, and a 12.91m lower zone of semi-massive, matrix and disseminated sulphide from 256.1m.

Logging and geochemical analysis by the CSIRO is expected to determine the Carr Boyd sulphide’s relationship to the T5 mineralisation discovered on the Carr Boyd basal contact 1km away to the northwest, Estrella reported.

The company said the intersection provides confirmation that massive sulphide mineralisation continues below the old mine workings and coincides with a downhole electromagnetic (DHEM) response modelled from the top portion of another diamond hole that was drilled into the basal contact last October.

The mine fault has been located and work will begin to identify the mineralisation’s off-set direction and distance in order to exploit its further potential.

Determining Carr Boyd’s relationship to T5

Estrella managing director Chris Daws said in addition to drilling, the company is highly focused on determining the Carr Boyd sulphide’s relationship to the T5 mineralisation found on the basal contact.

Estrella’s main aim is to prove or disprove the concept that the Carr Boyd mineralisation was derived from a much larger pool of sulphides located on the T5 basal contact. If proven, the opportunity exists that this large pool of sulphides still exists at depth.

“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,” Mr Daws added.
