MORE POTASH ASSAY RESULTS RETURNED
AND SCOPING STUDY UPDATE
South Boulder Mines Ltd (ASX; STB) is pleased to report that significant
preliminary potash assays have been returned from drilling conducted
within the current JORC/43-101 compliant Mineral Resource estimate area
in holes Col-006 and 007. The results continue to confirm previous visual
field estimates of mineralisation and provide encouragement that an
economic open pit mine can be developed. Extensive mineralisation has
been defined to date as detailed in the ASX release dated 19th January
2011.
In addition significant potash mineralisation has been intersected in new
diamond drilling to the southeast of the current resource (Figure 1). Drilling
is continuing as part of a 5,000m exploration program designed to define
and extend known resources. The results will be incorporated into the
current engineering scoping and feasibility studies.
Hole Col-006 intersected a total thickness of 24.49m of potash with a
combined 17.55% KCl including;
?? 0.77m of sylvinitite @ 23.40% KCl from 48.00m and;
?? 3.44m of sylvinitite @ 34.31% KCl from 51.12m and;
?? 1.04m of carnallitite @ 20.19% KCl from 54.56m and;
?? 7.16m of carnallitite @ 11.53% KCl from 70.60m and;
?? 9.73m of kainitite @ 18.90% KCl from 77.76m.
Hole Col-007 intersected a total thickness of 16.81m of potash with a
combined 16.44% KCl including;
?? 0.39m of sylvinitite @ 19.35% KCl from 24.98m and;
?? 7.10m of carnallitite @ 13.65% KCl from 38.29m and;
?? 9.32m of kainitite @ 18.43% KCl from 45.39m.
The best intervals of new potash mineralisation intersected outside the
current resource are as follows;
Hole Col-021B intersected a total thickness of 29.19m of potash including;
?? 16.47m of carnallitite from 84.94m and;
?? 12.72m of kainitite from 101.41m.
Collar details and potash mineralisation intersected for all new drill holes
are shown in Table 1. Geological details of previously drilled holes with
assays outstanding are available in the December quarterly report lodged
with the ASX on the 31st of January 2011.
