Metalex-WSR-Arctic Star Joint Venture Intersects 131.9 Meters of Semi-Massive to Near-Massive Sulphides in Hole 5.01-09, Under Hole 5.01-06, on Anomaly 5.01, James Bay Lowlands, Ontario

KELOWNA, BRITISH COLUMBIA--(Marketwire - June 16, 2008) - Metalex Ventures Ltd. (TSX VENTURE:MTX) ("Metalex"), WSR Gold Inc. (TSX VENTURE:WSR) ("WSR") and Arctic Star Diamond Corp.'s (TSX VENTURE:ADD) ("Arctic Star") Joint Venture Project along the Ring of Fire, 45 kilometers north of Noront's Eagle One discovery encountered another significant width of Volcanic Derived Sulphides (VDS) mineralization in hole number 5.01-09. This property, of 65 hectares, is one of 113 joint venture claim blocks under option by WSR, whereby WSR can earn up to a 50% interest in the property by spending $20 million over four years thereby diluting Metalex to a 45.75% interest and Arctic Star to a 4.25% interest. Currently Metalex has a 91.5% interest and Arctic Star has an 8.5% interest. Within the option agreement covering approximately 21,400 hectares, there are numerous other high priority targets throughout the area.

To date, on the 5.01 discovery 10 holes have been completed totalling 1903.5 meters. Hole 5.01-06, reported in a previous press release dated June 4, 2008 on Section 1+50 East was followed by three additional holes on the same section. Hole 5.01-10 was a 50 meter step out east of 5.01-09 on Section 2+00 East. The zone dips steeply north below the Precambrian surface which is overlain by approximately 15 - 20 meters of gravel and Paleozoic sedimentary cover. The VDS mineralization has been delineated thus far on sections 1+00 East and 1+50 East (50 meters apart) down to a vertical depth of 200 meters. On a 3rd section (2+00 East) the first hole completed (5.10-10) failed to intersect the zone at its targeted vertical depth of 150 meters.

Hole number 5.01-07 was drilled in a southeasterly direction to check for a north easterly - south westerly strike direction and encountered only minor iron sulphide mineralization.

Hole number 5.01-08 drilled southerly, across the assumed east - west strike direction encountered only sparse mineralization at shallow depths over the top of the main mineralization.

Hole number 5.01-09 drilled southerly, 50 meters down dip below hole 5.01-08 encountered the main zone from 103.5 meters to 235.4 meters (103.5 meters in total) in the drill hole and is similar in visible sulphide content to Hole number 5.01-06.

Hole number 5.01-10, a 50 meter step out to the east of hole 5.01-09 and along strike intersected only minor sulphides.

Hole number 5.01-11 currently being drilled is designed to test for the main mineralization down the steep easterly plunge, 50 meters below hole 5.01-10 on the same north - south cross section (2+00 East).

The following table summarizes the recent drilling on 5.01 with significant visual sulphide mineralization:

The anomaly 5.01 Project is managed and operated by Metalex for the Joint Venture partners under supervision of Dr. Charles Fipke, Chairman of Metalex. Dr. Fipke and John Harvey, P.Eng, a consulting geologist for WSR, prepared this release.

Metalex believes that the recent drill results, with the presence of visible copper, zinc and lead sulphides being observed on site by the project's geologist are very encouraging and could be of significant importance to the Joint Venture partners if the assay results pending are favourable. Notwithstanding the foregoing, visible observations are estimates only and pending assay results may not confirm visual observations in whole or in part. The widths given above are core widths only and do not represent true widths which cannot be determined at this time.

John Archibald, P.Eng. and a Qualified Person, has reviewed the drill core and confirms the visual descriptions described herein. Assay results are pending for all holes completed to date.

The TSX Venture Exchange has not reviewed and does not accept responsibility for the adequacy or accuracy of this press release.
