Mineral exploration firm Talisman Mining has intersected visible nickel-copper sulphides at Kerba prospect within its Livingstone project in Western Australia.
Strong nickel-copper enrichment in weathered rocks above sulphide-bearing host rocks was encountered, with a best assay of 6m at 0.47% nickel from 6m depth and 4m at 0.45% nickel from 18m.
The first-pass reverse circulation drilling also intersected high-magnesium ultramafic-mafic rocks with potential to host magmatic nickel-copper-platinum (Ni-Cu-Pt) sulphide mineralisation.
Recent phases of exploration at the Springfield project have been completed as part of an ongoing, multi-pronged strategy targeting volcanogenic massive sulphide and structurally controlled copper-gold mineralisation.
Coherent copper anomalism associated with a major north-west fault zone was identified by in-fill aircore drilling across the Lovejoy prospect on the Jenkins Fault Zone.
An ultra-detailed gravity survey has been completed over the Homer Volcanic Corridor to assist in defining key target horizons directly along strike from the DeGrussa mine, while processing and interpretation is currently underway.
The Livingstone project covers an area of 208km² about 130km north-west of Meekatharra.
The company has completed a detailed fixed-loop electromagnetic (FLEM) survey over the Kerba prospect in order to test highly conductive anomalies possibly associated with accumulations of massive nickel-copper-platinum group elements (Ni-Cu-PGE) sulphides within the Kerba ultramafic intrusive body.
Talisman Mining said three priority EM targets were identified, which were in part coincident with a coherent Ni-Cu-Pt in-soil anomaly and lie above the ovoid Kerba mafic-ultramafic intrusion.
An initial 4-hole RC drilling programme for 983m has been completed at Kerba to test for the presence of nickel sulphide mineralisation as well as to establish a platform for deeper down-hole electromagnetic (DHEM) surveying.
Drill holes LVRC001, LVRC002 and LVRC003 were drilled to intersect three FLEM plates with associated Ni-Cu-PGE soil geo chemistry, while LVRC004 was drilled down-dip of LVRC002, to provide a platform for DHEM at depth beyond the resolution of the FLEM survey data.
