Sydney - Thursday - July 23: (RWE Australian Business News) -
Cluff Resources Pacific NL (ASX:CFR) reports old tunnels with wooden
roof supports and backfilled with waste rock from the mining operation
have been exposed on the former Monte Christo mining lease (ML 16), on
the Bingara Diamond Field in northern NSW, beneath drillhole MCR 26.
Early this month the hole was interpreted as penetrating old
workings between 5.9m and 7.8m.
Bulk Sample Pit B MC 3 has been dug over this hole, and 11
gem-quality diamonds were recovered from a 30-tonne bulk sample.
Total weight of diamonds recovered was 2.07 carats.
Two black stones, together weighing 2.48 carats and tentatively
identified as carbonado, a finely crystalline, porous form of diamond,
were also recovered.
These stones stuck to the grease table and tested as diamonds
with the "Presidium Gem Tester", which measures thermal conductivity,
but left a red streak on a porcelain tile.
Carbonado has been previously reported from the Inverell Diamond
Fields Mine at Copeton.
Small pieces of sapphire and topaz were also recovered
