EXPLORATION UPDATE – MT TURNER PROJECT
The Mt Turner property is under option to
- A Phase 1 total of 31-line km of IP has been completed over the Mt Turner porphyry complex. The lines were spaced at 400 m with readings at 100 m along the lines (See Figure 1).
- The IP program has successfully identified a number of significant high-intensity chargeability anomalies indicative of sulphide mineralisation within a large felsic, porphyry style mineralising centre (see Figure 2) with strike lengths of up to 1.6 km and widths of up to 1.2 km. The largest anomaly remains open to the north.
- Coincident with and spatially related to the chargeability anomalies, detailed mapping has discovered a number of altered sub-volcanic and high-level volcanic intrusives, as well as an elongate, extensively altered, volcanic centre.
- Strike continuous chargeability anomalies have been identified in four main geological settings (See Figure 3):
- A flat-lying high chargeability zone at a depth of between 100 - 150 m on the eastern flank of the altered volcanic centre.
- Sub-horizontal and vertical deeper anomalies associated with the Mt Turner-type volcanic intrusives.
- Additional vertical anomalies associated with a NE trending western structural corridor.
- Anomalies associated with vertical altered sub-volcanic intrusives.
- The eastern flat-lying zone is characterised by a +40 millivolt/volt anomaly currently traced for a strike of 1.6 km (open to the north) with a width of up to 1.2 km. Initial interpretation suggests this anomaly could represent a secondary sulphide blanket or mineralisation associated with overlying impervious flat-lying volcanic units and underlying coarser units and flat granite fractures above vertical feeder structures — a classic trap site for hydrothermal fluids. The anomaly represents a previously unknown, significant near surface drill target.
- The sub-horizontal and associated vertical anomalies are associated with the annular Mt Turner and Mt
Turner East intrusive centres and provide important new data in defining significant porphyry drill targets at Mt Turner. Detailed field mapping has confirmed the contact of the intrusive and granite host is often occupied by annular hydrothermal and collapsed breccias intruded by late-stage pebble dykes. The clasts are rounded indicating transport and cemented in places by drusy quartz and gossan and display open space texture. In addition, quartz veined mineralised clasts within the breccia indicate that hydrothermal fluids have brought deeper mineralisation to the surface (See Figure 4). These hydrothermal breccias may have transported deeper porphyry style molybdenite mineralisation to the surface which has been identified in previously reported soil anomalies. Decompression breccias indicative of a porphyry environment have also been observed. - The western NE striking zone varies from 100 to 200 m wide and is currently 1.2 km in strike. Several zones of quartz veined gossanous breccias associated with fault slices of schist and altered granite intruded by rhyolite dykes are evident at surface. A significant (+40 millivolt/volt) vertical chargeability anomaly is coincident with a gold in soil anomaly on IP Line 3 and 5. Supergene copper mineralisation has been located at lower elevations associated with quartz veining. Several rock chips of surface mineralisation have been submitted for assay.

The Mount Turner Property lies in the western portion of the Georgetown Inlier, which constitutes the bulk of the proclaimed
The Proterozoic rocks have been intruded by Siluro-Devonian age granitic rocks during a period of subduction and underplating that is thought to have occurred during the Tabberabberan cycle of the Tasman Orogen (ca 430-380 Ma).
The Georgetown Inlier subsequently experienced a period of felsic intrusion and accompanied sub-aerial volcanism during the Carboniferous to Permian period (ca 350-230 Ma) associated with extension and rifting that developed during the Hunter-Bowen cycle of the Tasman Orogeny. This magmatism is termed the
The Permo-Carboniferous Mt Turner intrusive complex, which is centred within the property, consists of multiple phases of rhyolite to micro-granodiorite dykes, stocks and associated breccias, hosted by the Meso-Proterozoic Mount Turner Granite and metasediments of the Palaeo-Proterozoic Lane Creek Formation.
The property was initially examined under special Department Reserve during the 1975-78 field seasons by geologists of the Australian Government's
The subsequent report (Baker & Horton, 1982) described the intrusive complex as a porphyry copper- molybdenum system with zoned polymetallic mineralisation. The report was based on 11 widespread, shallow vertical drill holes, <100 metres in depth and four diamond holes, only one of which was located near the intrusive centre. None of the drill holes were assayed in their entirety.
A portion of Mt Turner was held by
Essex currently owns 100% of the Mt Turner property.
