King River Copper claims new Speewah Dome discovery
THE DRILL SERGEANT: King River Copper (ASX: KRC) has claimed discovery of visible surface copper occurrences on the company’s projects located in the north eastern corner of in the Speewah Dome in Western Australia.
The new prospect area, which the company has named Chapman, was discovered by its geologists while they were conducting follow-up work on the source of a broad arsenic-in-soil anomaly and spot gold-in-soil anomaly.

The company said numerous copper occurrences appear at Chapman, which are located in a one kilometre-long, north-west trending zone at the foot of a high escarpment, five kilometres north of the Greys-Hayden prospects.
Preliminary field analysis by Niton XRF has indicated these Chapman occurrences host a similar suite of mineral elements to that of the Greys-Hayden area, including copper, silver, lead, arsenic, antimony, bismuth, scandium, mercury and tin.
King River explained the need for the Niton field analyser results to be validated by laboratory assay, and to that end rock samples have been dispatched from the field.
The company anticipates those results will be available in two to three weeks.
King River said it has observed copper mineralisation has been observed in two different settings at Chapman: the first being sub-horizontal quartz veins and breccia along the sediment-granophyre contact; with the second being a hematite and quartz breccia in structure dipping 40 to 50 degrees northwest in granophyre and siltstone.
The company has lodged a program of works with the Department of Mines and Petroleum for drilling the soil covered areas at Greys-Hayden, Todhunter and Kings targets.
It will also submit a programme of works for drilling the new Chapman target once assays are received from a recent field survey and after further mapping and sampling is undertaken to define drill targets.
“The Directors are very excited by the discovery of this new copper prospect,” King River Copper said in its ASX announcement.
“Its location on the edge of the Speewah Dome associated with the targeted granophyre-sediment contact, with iron oxide rich breccia structures in the granophyre that have not been previously observed at Speewah, has opened up the potential for further discoveries of copper / gold mineralisation around the 30 kilometre-long Speewah Dome where this stratigraphic-structural configuration is found.”
