KING River Copper has developed two exploration models to explain high grade copper, gold and silver surface results at Speewah Dome in Western Australia. The models will be used to direct drilling in May with a new portable diamond core rig arranged for this program.

The Chapman, Catto and Greys prospects are thought to be controlled by the intersection of flat dipping sulphidic quartz veins with the target horizons and major sub-vertical faults.

Certain aspects of the geology at Speewah match criteria for development of an iron oxide copper gold deposit. These include evidence of deep ultramafic activity on a regional scale, potassic alteration associated with major structures and mineralization, and associated minerals containing silver, bismuth and light rare earth elements. Such bodies often form pipe like bodies of brecciated material with strong hematite/magnetite alteration and associated high grade mineralization.

Of particular interest is Chapman deposit where high grade copper (39%) and gold (4 grams/tonne) mineralization with elevated bismuth and uranium are associated with a hematite breccia on the edge of a circular feature.

Prior to the drilling helicopter reconnaissance programs were undertaken in April with the targets including extensions to faults identified over the Chapman outcrops; Todhunter South and West; primary Todhunter and Pentecost fault intersections; Eiffler Hills; Eiffler North anomaly; and several untested potential litho-structural targets within the Speewah Dome.

King River’s exploration in 2014 has been divided into two phases. Phase 1 has been costed at $444,000 while phase 2 will cost $1 million. Under the first phase, exploration will target copper-gold-silver mineralization at specific, shallow, litho-structural positions.

The company will drill 11 diamond holes at Chapman, Catto West, Eiffler North, Todhunter Main and Todhunter South using a portable diamond drilling rig that allows early access to seasonally restricted project and drilling in steep/difficult terrain. About 250 rock chip samples will also be taken to test areas for copper-gold mineralization at major structural intersects in known prospective lithologies.

Subject to the results from phase 1 drilling, phase 2 will extend any mineralization intersected as well as complete drilling at Chapman Flats, Catto West, Catto East, Chapman Flats North, Eiffler North, Todhunter North and Todhunter South. Phase 2 will consist of 2500 metres of shallow rotary air blast/reverse circulation drilling, 85 deeper targeted reverse circulation holes totalling 1000 metres and between 5 and 10 diamond holes.

The company will also acquire 2000 soil samples and 400 reconnaissance rock chip samples. These will be carried out in areas of known prospectivity and untested areas, especially south of Todhunter.
