Junior explorer Estrella Resources (ASX:ESR) has delivered significant high-grade magmatic nickel sulphide results from the T5 discovery zone at its flagship Carr Boyd project in Western Australia.
Assay results from diamond core hole CBDD030 confirm the high-grade nature of the magmatic nickel sulphides at T5 after a Down-Hole Transient Electro-Magnetic (DHTEM) survey of the hole intersected significant massive Ni-Cu (and PGE) bearing sulphides deep below the T5 discovery zone.
Results returned comprise a high-grade massive sulphide zone of 2.5m @ 3.66% Ni, 0.46% Cu, 0.16% Co, 2.09g/t Ag & 0.78g/t Au+Pt+Pd.
In addition, the combined massive and matrix sulphide zone returned grades of 3.7m @ 2.85% Ni, 0.65% Cu, 0.13% Co, 2.58g/t Ag & 0.75g/t Au+Pt+Pd.
These are located within the much broader mineralised zone returning an overall grade of 13.9m @ 1.07% Ni, 0.39% Cu, 0.05% Co, 1.56g/t Ag & 0.48g/t Au+Pt+Pd.
Grade is King and with assays returning +3.5% nickel, this is an absolutely fantastic result,” Estrella CEO Chris Daws said.
“It’s going to get interesting from here on in as we drill out this high-grade nickel discovery and test the surrounding area for further mineralisation.
“Well done to the entire team and I look forward to seeing what the future holds for us as we unlock the true potential of the T5 mineralisation.”
The results support the potential for mineralisation to be high-grade and low in deleterious elements, which is a typical feature of magmatic nickel deposits compared to many komatiite nickel deposits, Estrella noted.
Follow up diamond core drilling using two drill rigs is scheduled to begin imminently.
