Kookaburra Resources (TSE) is encouraged by initial results from drilling on the Tacaza copper project in southeastern Peru.
The company received results from the first five holes of a 175-hole reverse circulation program. The holes were drilled at 50-metre intervals along section 4+00S, between two areas of old underground workings. Previous mining at the Tacaza property concentrated on selectively mining sulphide mineralization grading in the region of 20% copper for processing in a 35-ton-per-day flotation plant.
The property hosts several flat-lying, high-grade copper oxide- and supergene-enriched secondary copper sulphide horizons.
The old workings are spread over four general areas, covering a strike length of more than 900 metres from sections 2+00S to 11+00S.
The first two holes of the current program missed the stratabound zone, while the third intersected 12 metres, starting from surface, grading 1.45% copper. Hole 4 intersected 16 metres grading 1.43% copper from 16 to 32 metres and Hole 5 intersected 20 metres grading 2.56% copper from 16 to 36 metres. Kookaburra hopes to outline a large copper reserve minable by open pit and amenable to solvent extraction-electrowinning.
Preliminary metallurgical tests indicate that more than 95% of the contained copper is acid-soluble.
