Zambezi Resources said Wednesday that the 2008 drilling campaign (Kangaluwi Copper Project) has been underway since May with up to 6 rigs on site and to date, 26,000 meters of drilling has been completed so far this season.
Further encouragement has been received from the first systematic RC drilling ever conducted at the Chisawa Prospect, which is located 2.5km to the south east of Zambezi's flagship Kangaluwi Prospect, it said.
New RC drillhole intercepts from Chisawa include: 14metres at 1.52% copper, 12metres at 1.36% copper, 10metres at 1.23% copper, and 14metres at 0.65%.
Further assays are awaited to confirm strong zones of visual mineralisation observed in drilling, it said.
The mineralised zone remains open down dip and along strike to the east and west.
The company said, mineralisation at Chisawa consists of chalcopyrite, bornite, malachite, azurite and secondary chrysocolla in the oxide zone.
The host sequence consists of sheared metasediments, metavolcanics and a late stage, conformable coarse grained felsic pegmatite.
Mineralisation is hosted within strongly foliated garnet-quartz-biotite-muscovite schist and feldspar-quartz-muscovite-kyanite pegmatite, it said.
Mineralisation dips moderately to the south west at 30-40 and occurs within the sheared southern limb of an overturned ESE-plunging regional synformal fold.
Initial drilling at Chisawa targeted surface malachite mineralisation coincident with a 250ppm copper in soils geochemical anomaly over a north west - south east trending strike length of 7.2km.
The significant results reported here come from the core of this anomaly which consists of a 3.1km strike length at 1000ppm copper in soils.
The soil geochemistry conforms to a mapped and interpreted lithological and structural corridor, it said.
A strong correlation between the 1000ppm Cu contour and higher grade copper mineralisation is evident in the RC drilling.
Drill testing of this zone to date is via widely spaced drill sections with a nominal distance between sections of 200-400metres.
The greater Kangaluwi project covers in excess of 28km of strike length and detailed drilling has tested only 3.5km strike length to date at Kangaluwi.
At the neighbouring Chisawa prospect, drilling has sparsely tested only 3.5km strike length.
The company said 75% of the estimated total prospective strike length of the greater Kangaluwi project remains to be drill tested.
