Snowfield Updates Bulk Sample Results

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 10, 2008) - Further to Snowfield Development Corp.'s ("Snowfield" or the "Company") (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.
