COPPER / GOLD PROJECT

King River Copper Limited (“King River” or “the Company”) (ASX: KRC) has a new discovery of visible surface Copper occurrences in the north eastern corner of the Speewah Dome (Figure 1).

This new prospect area will be called ‘Chapman’. It was discovered by our geologists following up the source of a broad arsenic-in-soil anomaly and spot gold-in-soil anomaly located to the west.

The numerous Copper occurrences at Chapman are located in a 1km long, north-west trending zone at the foot of a high escarpment (Figure 2), 5 kilometers north of the Greys-Hayden prospects.

Preliminary field analysis by Niton XRF indicates 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. The Niton field analyser results need to be validated by

laboratory assay, and rock samples have been dispatched from the field with results expected in two / three weeks.

The Copper mineralisation has been observed in 2 different settings at Chapman (Figure 3):

1. sub-horizontal quartz veins and breccia along the sediment-granophyre contact; and

2. hematite and quartz breccia in structure dipping 40-50° to northwest in granophyre and siltstone

One of our prime exploration target concepts is that Copper / Gold mineralisation is best developed at the intersection of favourable lithologies (such as the felsic granophyre and siltstone) with fault zones acting as conduits for mineralisation. Since the newly discovered mineralisation at Chapman is associated with the targeted felsic granophyre horizon and its contact with the overlying sediment (and is 5km north of the Greys mineralisation), it provides encouraging validation of the target concept. The structural setting, orientation and mineralogy indicates multiple mineralised structures and demonstrates the potential for further discovery in the 7.5km long, sparsely tested Greys-Hayden priority target area.

A Programme of Works has been lodged with the Department of Mines and Petroleum for drilling the soil covered areas at Greys-Hayden, Todhunter and Kings. A Programme of Works will be submitted for drilling the new Chapman target once assays are received from the 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. 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 30km long Speewah Dome where this stratigraphic-structural configuration is found.

CORPORATE

SHARE BUY BACK

On 23 July shareholders approved an extension to the share buy-back to acquire up to an additional 13.8 million shares over the next 12 months. The Directors have decided that pursuant to the planned drilling programmes that they will not purchase shares higher than 4 cents in the foreseeable future to preserve funds for these drilling programmes.
