Further to Snowfield Development Corp.?s (?Snowfield? or the ?Company?)
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 0.850 mm, 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.
