SAINTE-FOY, QUEBEC -- (MARKET WIRE) -- 06/28/06 -- Plexmar Resources Inc. (TSX VENTURE: PLE), is pleased to announce results from its Bolsa del Diablo property. Results from 160 samples were received from ALS Chemex, in Lima.

Channel, chip and composite samples were taken on the Angolos concession, Santa Rosa de Suyo and Molinetes 2004 concessions where local miners have recently uncovered new vein type structures in highly altered volcanic and intrusive rocks.

VEINS

Channel samplings taken in the newly discovered veins vary from 0.5m to 1.0 m in width and are taken at an average depth of 1m. Results are encouraging and the most significant values are tabulated below:

The SAM and VPRM series of samples were taken from newly uncovered veins and from the intrusive and volcanic units in an area located in the northwestern part of the Angolos concession some 150 meters north of the results published in the last press release dated June 1(st) 2006. The area is close to a contact between the intrusive and altered volcanic unit.

Guy Bedard, president says: "Theses are the best values encountered so far on the Bolsa del Diablo project and are obviously first rate drill targets. They confirm the high potential to find a large disseminated gold orebody with high grade gold veins".

Geologists continue to map and refine the geological model. Trenching and sampling is ongoing and will remain so even during the geophysical surveys.

The airborne magnetic and radiometric survey has been awarded to Fugro Geophysical services out of Lima. Over 1865 line Kms will be flown and will cover the whole property (220km2). The induced polarization ground survey will be awarded this week.

All samples are analyzed by ALS Chemex in Lima. Guy Bedard, president, acted as the QP for the preparation of this news release.

On Bolsa del Diablo

Plexmar controls over 220 km2 of land in Northern Peru near the border with Ecuador. At the present, over 250 artisan miners are pulling gold on a daily basis from trenches or pits located in an area measuring approximately 6km2 roughly centered within Plexmar's main claim block. The zone is characterized by low to intense silica and clay hydrothermal alteration. All the volcanic rocks in the area of interest show pervasive argillic alteration and have developed very intense stockwork structures. Gold mineralization occurs partly as fracture fillings in the stockwork and also as dissemination throughout the rock. Limonitization is pervasive throughout the rock. This intense stockwork was observed in numerous places on the property.
