Blackthorn Resources Limited (ASX:BTR) is pleased to advise that final copper assay results have been received from the Phase 5 drilling program at Mumbwa, Zambia. Copper assay results have been received from drill holes S36-037, S36-039 and S36-040.
The Phase 5 drilling program commenced in August 2011 and completed drilling of 21 holes for a total of 10 934.31 meters.
Sampling and assaying of the drill core collected follows a standard site protocol with samples of half core being submitted to the AH Knight Laboratory in Kitwe, Zambia for preparation and copper analysis. A representative sample split is taken from each batch and sent to ACME Analytical Laboratories in Vancouver, Canada for gold analysis.
A cut-off grade of 0.25% Cu was applied when delineating the drilled thickness intervals of mineralisation, with weighted average grades reported. True-widths are not quoted as further work is required to determine the geometry of the mineralisation. No upper limit has been applied to copper or gold grades in these exploration results.
