Epanko Metallurgical Update
Kibaran Resources Limited (ASX:KNL) is pleased to provide the following
technical update from the ongoing variability testwork being carried out as
part of the Bankable Feasibility Study (BFS) on its Epanko Graphite
Project in Tanzania. The variability flotation testwork was focussed on
evaluating whether any differences in metallurgical performance occur
across the different mineralized bodies within the Epanko graphite deposit.
Testwork carried out to date has confirmed that Epanko flake size
distribution is consistent across:
- Grade boundaries ranging from 5% to 20.3% total graphite carbon ("TGC")
- Weathered, Transition and Fresh Rock Zones
- Variable geological and mineralogical units
The variability flotation testwork results are summarised in Table 1 below.
Figures rounded to 1 decimal point. Micron (μm) and Millimetre (mm). 1mm =
1000μm and graphite carbon content determined by loss of ignition
method (LOI) and by drying at temperatures in the range of 400 °C
The figures below show the cumulative % retained charts which emphasise the
higher percent retained at each size fraction and also show a slightly
