Kalumbila pit in-fill drilling shows good results confirming strike and dip
continuity
The Board of Kiwara, the Zambian based exploration and mine development Company,
is pleased to announce the first results of its in-fill drill programme at
Kalumbila, which continue to report thick intersections of copper at or above
base model grade.
Highlights:
* In-fill drill programme results demonstrating continuity from near surface to
target depth;
* Borehole ("B/H") L57 intersected 20.4m grading 0.94% Cu from 12.8m and 45.6m
also grading 0.94% Cu from 167.6m;
* B/H L47 intersected 49.2m grading 0.89% Cu from 218.6m;
* B/H L56 intersected 59.6m grading 0.69% Cu from 254.4m, including 19.4m at
1.06% Cu from 289.3m;
* B/H L60 intersected 58.0m grading 0.75% Cu from 139.0m including 16.1m grading
1.10% Cu from 157.7m.
Colin Bird (Chairman) says: "This in-fill drilling programme is designed to
advance the project to feasibility study. In so doing the key issue to address
is continuity, both strike and dip. I am pleased that these results confirm such
continuity and also show good widths of significantly higher grade than the base
pit model. We are continuing to aggressively drill the pit area with a view to
optimisation and possible extension, which these results appear to support."
Background:
On 5th October 2009 the Company announced that Snowden Mining Consultancy had
been engaged to advise on a pre-feasibility study at Kalumbila; the initial
focus of the study would be on the open-pittable mineralisation has been
identified by Snowden to contain an Inferred Resource of 340 million tonnes at a
grade of 0.78% copper (using 0.55% total Cu reporting cut-off) on which the
objective would be to raise the resource from Inferred to Indicated with an
in-fill drilling programme, and that additional drilling would be undertaken
both to the northeast and southwest of the pit target to seek extensions.
The current phase of the infill drilling programme is designed to get the
necessary confidence to optimise pit design at a stripping ratio of not greater
than 4.5 1. The results are demonstrating this continuity from near surface to
prescribed target pit depth.
Kalumbila Drilling Results:
B/Hs L46 - L47 and L56 - L60 are diamond core boreholes: B/H L47 is 400m east of
the Company's previously reported B/H L27, B/H L56 is down-dip of L27. B/H L57
is 200m west of L27 and B/H L60 is 200m up dip of L57; these B/H are within the
open-pittable target delineated by Snowden. B/Hs L58 and L59 are 100m and 500m
respectively to the east of the pit target; L46 is 2,400m west of pit target.
The selected length weighted mineralised intersections for which a cut-off grade
of 0.30% Cu was applied, are summarised in the table below:
