VANCOUVER, BRITISH COLUMBIA (TSX VENTURE: SNO) news release of
March 3, 2008 (NR 08-08) reporting results from a 1,044kg sample of
concentrate from its Mud Lake kimberlite complex, processed at the
Saskatchewan Research Council's ("SRC") lab in Saskatoon, it is the
Company's intention to carry out additional testing on this
sample.
Snowfield believes that diamond recovery may have been hampered
by the coarse crush size as well as the presence of hematite that
is known to occur throughout the kimberlite. If the diamonds were
not fully liberated from crushing, or covered with a hematite
coating, it is possible they would report to the reject fraction.
It is Snowfield's intention to audit a portion of the concentrate
from both the x-ray accepts and rejects using caustic dissolution
to determine if there were diamonds that were not recovered due to
insufficient crushing or the presence of hematite material coating
the diamonds. Recent sample results (NR-08-08) reported a bottom
sieve size of 0.850mm, however the lower cutoff during the initial
kimberlite processing was 1.4mm, possibly explaining the paucity of
finer stones recovered.
The balance of the concentrate yielded from the initial 100
tonnes processed by DeBeers Canada Exploration Ltd. (DeBeers) at
their Grande Prairie, AB, Dense Media Separation (DMS) Plant is
still in custody. Kimberlite processed through the DeBeers DMS
circuit was crushed to a top size of 12.5mm. Snowfield will discuss
the possibility of a secondary crush to a smaller size fraction
with DeBeers. This secondary crush would assist in the liberation
of any diamonds missed in the initial procedure. A routine audit of
a portion of the DMS "floats" or reject material from the DMS
circuit will also be undertaken by a separate DMS facility, yet to
be determined.
Snowfield has now moved their delineation drill to the Mud Lake
kimberlite and drilling has commenced to further test the
kimberlite that has been identified on three separate horizons.
Split core samples will be collected under chain of custody from
each of the horizons and treated by caustic dissolution to
determine if there are variable diamond populations between the
kimberlite sheets.
Exploration drilling at the Ticho Project continues and further
updates can be expected. The 2008 exploration program is under the
supervision of Jennifer Burgess, P. Geol., a qualified person under
NI 43-101.
