Company Announcement: Ground EM Survey Commences at Springfield
This article has been supplied.
Talisman Mining Ltd is pleased to advise that ground-based Fixed Loop Electromagnetic surveys (FLEM) have commenced over two high-priority electromagnetic target areas identified recently at its 100%-owned Springfield Copper-Gold Project.The targets, which are located within the Kink Prospect of the Southern Volcanics, were identified from a recent Versatile Time Domain Electromagnetic (VTEM) survey.The identification of these late-time EM responses has opened up an exciting new front for exploration at Springfield. Late-time channels are those typically assessed for massive-sulphide style mineralization and may reflect bodies with stronger conductive characteristics.
The FLEM surveys at the Kink have been designed to test for bedrock conductors that are possibly associated with massive sulphide copper-gold mineralisation over the target areas at VTEM-2 and VTEM-3 and to help better define targets for subsequent drill testing.
“The Kink” Prospect
At the Kink Prospect, three anomalies have been identified that warrant follow up. These priority targets (VTEM-1, VTEM 2 and VTEM-3), are summarised below:
VTEM-1 is a clear late time anomaly persisting to channel 43 on several lines, but with a relatively discrete core (200-300m) which may indicate the presence of multiple layered conductors. A direct RC drilling programme is currently being planned to test this anomaly;
VTEM-2 is a strong, but broad cluster of late-time anomalies apparently associated with paleo-drainage, but with a discrete "hot-spot" over a strike length of 500-600m. Recent geochemical drilling returned maximum bedrock copper values to 1,140ppm Cu in the vicinity of VTEM-2; and
VTEM-3 is another strong, but broad cluster of late-time anomalies located immediately north of VTEM-2 along an interpreted NNW trending fault structure which also has elevated bedrock copper geochemistry in nearby shallow drilling.
The Wedge Prospect
Several mid-late time VTEM anomalies have been also identified at the Wedge Prospect, which is coincident with several coherent zones of elevated copper mineralization along the Goodin Fault zone with copper values up to 1,240ppm Cu (see ASX Announcement – 25 March 2013). Anomalies VTEM-9 to 11 at the Wedge are discrete, linear mid-late time features associated with the Goodin Fault and appear to cluster near the confluence of the Goodin Fault within a prospective mafic-sediment volcanic sequence. Detailed mapping and soil sampling (1,600 samples) has been recently completed at the Wedge to test for surface indications of copper-gold mineralization over these anomalies and along the length of the Wedge volcanic sequence to further refine possible future drill targets.
