Mt Ida is located 200 km north-west of Kalgoorlie-Boulder, 125 km from the Davyhurst Processing Plant and hosts the high-grade underground Baldock deposit (Mt Ida).
GEOLOGY & MINERALISATION
The Mt Ida Project area is in the northern-most part of the Mt Ida (or Ularring) greenstone belt containing an extensive sequence of mafic and ultramafic rocks with interbedded (volcanogenic) sediments and felsic to intermediate volcanics. In the Mt Ida area the greenstone belt is folded into a southerly plunging antiform called the Kurrajong Anticline which has the Copperfield Granite at its core.
Historically some 306,000 ounces of gold have been mined from the various mines in the Copperfield / Timoni area with most of this coming from the Timoni mine. The Timoni mine commenced in the late 1950 and was mined for several years extracting some
265,000 Ounces of Gold at an average head grade of 16.3 g/t Au.
The two main mineralised shears are the Timoni and Dave lode systems which are parallel mineralised shear zones within amphibolite (Timoni) and anorthosite (Dave) on the western flank of the Kurrajong Anticline.
The mineralised shears range in width from 0.75 – 2 metres with gold associated with quartz veining, sulphides, and biotite-chlorite alteration. There is also a strong association between gold and copper mineralisation within the Dave lode.
The recent focus has been on exploration and development of the Dave lode which hosts the current Whinnen, Meteor and Baldock resources.

The company is primarily focused on exploring and developing the high-grade Dave lode and extensions to the Timoni lode. Other advanced targets include:
Bombay: The anomaly has a strike-length of approximately 3.5 km defined by irregular auger geochemistry and RAB drilling. There appears to be immediate potential to define a supergene resource within the prospect, and targeted deeper drilling may intersect higher grade bedrock shoots.
West Nell: West Nell prospect was originally identified as a 500m long N-S trending +20ppb gold in auger anomaly with associated anomalous copper. Historical RAB drilling of this auger anomaly identified significant gold in weathered sheared anorthosite including 8m @ 2.6g/t & 10m @ 1.5g/t. Mineralisation is associated with quartz veining and ex-sulphides within sericite-fuchsite schist with biotite alteration.
