Estrella Resources extends T5 Deposit at Carr Boyd Nickel-Copper Sulphide Project in Western Australia

Estrella Resources (ASX:ESR) reports it has extended the T5 Deposit at its 100% owned Carr Boyd Nickel-Copper Sulphide Project in Western Australia with a new intersection.

The company reports the T5 Deposit continues south of a large Proterozoic Dyke without any significant structural offset at Carr Boyd, located 80km northeast of the Kalgoorlie-Boulder.

Drillhole CBDD078A has intersected 1.8m of semi-massive to globular sulphides from 929m downhole within a broader 21.2m mineralised halo.

Commenting on the results, Estrella Managing Director Chris Daws said: “Drilling at T5 has again provided our team success with a significant step out hole south of the late-stage Proterozoic Dyke, encountering significant nickel and copper sulphides.

“Drilling at T5 has again provided our team success”

DHEM will be a significant advantage as we follow the extent of the T5 Deposit.

We continue to actively explore the Carr Boyd basal contact as we know that is the most likely place to find significant accumulations of nickel and copper sulphides. It has yielded two solid discoveries so far at T5 and Broonhill.

At Gossan Hill, we are kicking off our first diamond drilling program this  week and I’m looking forward to seeing the results and updating shareholders.”

CBDD078A was targeting the down-plunge continuation of the T5 Deposit 300 metres south of previous drilling, and south of a disrupting Proterozoic Dyke.

The company reports that the drillhole intersected a 21.2-metre-long zone of disseminated to blebby nickel-copper sulphide mineralisation, including 1.8m of semi-massive and globular nickel-copper sulphides at the bottom of the interval on the basal contact.

The lower sulphide contact occurs on an offshoot from the Proterozoic Dyke, however the majority of primary mineralisation appears to remain intact and has not been remobilised.

Drillholes CBDD067A and CBDD067B were wedge holes targeting a downhole electromagnetic (DHEM) plate north of the Proterozoic Dyke generated from their parent hole CBDD067.

The wedge holes intersected remobilised nickel-copper sulphide mineralisation. The large Proterozoic Dyke has infiltrated the basal contact in this area and disrupted mineralisation.

Further drilling is warranted to identify the location of the remobilised sulphides and this work will be undertaken in due course once the regional program has concluded.

Estrella is awaiting the DHEM team to arrive on site to conduct surveys on the DHEM platform holes between the T5 Deposit and the Broonhill Deposit.

Meanwhile, the company identified Gossan Hill as a potential mirror-image to the T5-Broonhill basal contact and mapping confirmed the prospectivity of the area mid-2021.
