======================================================================= Re: News Releases - Thursday, May 20, 2010 Troymet Mobilizes Crews to Key Project ======================================================================= May 20, 2010 - Troymet Exploration Corp.

(TSXV:TYE) ("Troymet" or the "Company") reports that exploration crews have mobilized to the Companys 100% owned Key property, located 125 km southwest of Vanderhoof, British Columbia.

The strategically located 7,882-hectare project is prospective for both precious metals and volcanogenic massive sulphide (VMS) discoveries.

The exploration program, which will include diamond drilling, will initially focus on three target areas where anomalous gold values are currently recognized (News Release - April 28, 2010): The Company believes the gold mineralization on the adjoining Blackwater project (Richfield Ventures Corp.) may extend onto the Key project.

Richfield has identified a bulk gold deposit (September 25, 2009 news release) on the Blackwater project and plans a major drilling program in 2010 to define a NI 43-101 compliant gold resource (March 30, 2010 news release).

In addition, the Key property is prospective for bonanza-style, epithermal gold-silver mineralization similar to the adjoining 3Ts deposits, and the geology and geochemical signatures also have strong parallels to that of the gold- and silver-rich Eskay Creek deposit in northwestern British Columbia Tracy Hurley, P.Geo., Vice President, Exploration and qualified person as defined by National Instrument 43-101 is responsible for the technical information provided in this release.
