TORONTO, ONTARIO, May 01, 2008 (MARKET WIRE via COMTEX News Network) --

Seafield Resources Ltd. ("Seafield" or, the "Company")(TSX VENTURE: SFF), is pleased to announce results from the 2007 drill program conducted by NWT Uranium Corp. on the polymetallic Picachos project in Mexico. Highlights include a 47.1 metre intercept of 83 grams per tonne (g/t) silver and 0.84% combined zinc-lead, which starts at surface. The richest silver intercept returned 509 g/t silver and 0.56% zinc-lead over 3.0 m. Significant gold and zinc-lead results included a 1.52 metre interval of 6.2 g/t gold, 348 g/t silver and 19.9% zinc-lead. The mineralized zone has been evaluated to a minimum strike length of 500 m.

"We are very encouraged by these drill results, which confirm the bulk mining potential at Los Cochis," said Marek J. Kreczmer, President and CEO of NWT Uranium, which is earning a 70% interest in the property from Seafield. "The Picachos project is in the Sierra Madre Occidental Ignimbrite Belt, which is one of the largest silicic volcanic fields on Earth, and is traditionally known for high-grade epithermal gold and silver deposits such as Tayoltita and Rosario. We look forward to additional drilling to confirm the Los Cochis orebody shape and test its extensions, as well as explore other three main mineralized zones of the Picachos property."

Results

A total of 21 reverse circulation (RC) holes, representing 3,125 m, were drilled in November, 2007. Of the 21 holes drilled, 18 targeted the main silver soil geochemical anomaly on seven lines, spaced 100 m apart, with most holes dipping to the southwest. Of particular note, holes COCH3, 6, 13 and 20 were drilled from the same location in four different directions as a preliminary shape investigation of the mineralized zone. Additionally, two holes tested an IP anomaly located 250 m east of the main zone, while one hole (COCH15) tested a gold soil anomaly. Selected analytical results are detailed in the following table:

The intercepts reported are RC mineralized intercepts. True width of the mineralized zone cannot be estimated at this stage. The targets drilled at Los Cochis tested old workings and high silver geochemistry on surface, identified through an extensive soil geochemical survey conducted in 2005. Specifically, rock-chip channel and grab samples returned individual values of up to 4,975 g/t silver, 8.61 g/t gold, 53% zinc, as well as 50% lead, as detailed in a news release in Stockwatch on Oct. 31, 2007.

The drilling intercepted mostly andesitic volcano-sedimentary rocks, with some andesitic flows and dikes, and quartz feldspar porphyritic dikes. Mineralization occurs in propylitic-altered andesitic rocks, and consists of galena, pyrite, sphalerite, tetrahedrite and chalcopyrite.

Quality control/assurance

Sampling was supervised by Michelle Robinson, MASc, PEng, who is a qualified person, as defined by National Instrument 43-101, and a consultant to NWT Uranium. Ms. Robinson has supervised the preparation of this news release.

Dry and wet RC drilling samples were routinely collected at five-foot intervals, and reduced using cyclone and Jonas splitter. Samples were transported to Acme Analytical Laboratories in Guadalajara for preparation, and pulps were sent to Acme's Vancouver office for assay (ICP-MS). Samples containing more than 0.3 g/t gold, 50 g/t silver or more than 1% base metals were reanalyzed using a 30-gram fire assay for gold-silver, and high-grade multi-element ICP methods. Blind standard pulps were inserted into the sample stream roughly every 25 samples to check for within-batch analytical precision.

As previously announced in a December, 2007, news release, 2,050 total samples were collected through the drill program. Drilling was conducted by Layne de Mexico SA.

A total of 88 drilling samples were selected from both mineralized and non-mineralized intercepts from the backup splits in camp, and sent to SGS Minerals Services in Durango, Mexico, for gold and silver analysis. Of the 88 samples, only two report significant differences between Acme and SGS.
