Chrysalis Resources (ASX:CYS) has commenced reverse circulation drilling on its Bulala Hills copper project in south-western Zambia.
The program aims to identify potential for economic copper mineralisation within a semi-continuous 1 kilometre by 4.5 kilometre copper-in-soil anomaly containing 107 XRF values greater than 200ppm.
Drilling is targeting high grade supergene copper mineralisation beneath the highest copper-in-soil results including 1100ppm, 1066ppm, 971ppm and 818ppm from within the central parts of the anomaly.
Mapping, and interpretation of airborne magnetic data suggests that copper mineralisation is associated with a steeply dipping shear zone containing a quartz porphyry intrusive displaying strong argillic alteration and a hematite breccia unit on its northern contact.
The program is expected to be completed in 2 to 3 weeks.
Chrysalis has also recently commenced a 4,400 metre aircore drilling program on its Kabwima copper project in north-western Zambia.
This program aims to identify the potential for economic copper mineralisation within a 5.5 kilometre long, up to 1.6 kilometre wide, continuous copper-in-soil anomaly of greater than 100ppm.
The current geological model here focuses on supergene copper enrichment at 30 metres below surface near the faulted contact between carbonate and graphitic shale units.
Chrysalis also holds zinc-lead prospects in Western Australia at Gregory Range, where it recently identified historic zinc-lead intersections drilled by WMC and BHP between 1985 and 1996.
Infill drilling and follow-up drilling along strike is planned.
Chrysalis is lightly valued at under $4 million.
