Selwyn Resources Announces Improved Metallurgy for XY Central High-Grade Mineralization

Vancouver, BC, June 14, 2010 – Selwyn Resources Ltd. (SWN.TSX-V) is pleased to provide an update to investors on the projected zinc-lead metallurgical performance at the Selwyn Project. The recent testwork continues to indicate that there is good predictability of metal recovery and concentrate quality. In particular, the high-grade nature of the Selwyn zinc concentrates and their low iron content are attractive to zinc smelters.In June 2009, Selwyn engaged G&T Metallurgical Services Ltd. (“G&T”) based in Kamloops, British Columbia to assess the metallurgical performance of higher grade mineralization from the XY Central zone and develop a process flow sheet. This work was under the direction of Peter Taggart, P. Eng., Selwyn’s Independent Qualified Person for metallurgical and process testwork, who has also reviewed the content of this news release. The latest G&T testwork confirms their previous testwork program in 2007 that demonstrated good metal recoveries to high-grade saleable zinc and lead concentrates (see December 4, 2007 News Release). G&T’s 2010 testwork results will be incorporated into Wardrop Engineering Inc.’s (“Wardrop”) ongoing bankable feasibility study (see January 5, 2010 News Release).

G&T KM2427 Program Metallurgical Results
G&T’s 2010 testwork utilized a 6.6 tonne sample of XY Central mineralized material from which a composite was extracted grading 10.1% zinc and 4.02% lead. The program recommended a conventional flow sheet and a primary grind to 40 microns (80% passing). Based on the G&T testwork results, it is projected that, under operational conditions, 85% of the zinc is recoverable to a 55% zinc concentrate with low iron content; and 69% recovery of lead to a lead concentrate grading 60% (see table).

No secondary metals or minor elements of the zinc or lead concentrates are expected to attract smelter penalties, with the possible exception of a modest silica penalty in the zinc concentrates. The silica content of the zinc concentrates varies depending on grade of zinc in the concentrates – higher zinc grade corresponds with lower silica content. The concentrates contain measurable quantities of potentially valuable minor metals such as gallium, germanium and cadmium, but the grades are expected to be variable and no smelter payment is anticipated at this point in time.
