Trio Gold Corp.: San Ramon Yields Additional High-Grade Copper Intercepts: Hole #12 Assays 23.0% Cu and 2.02 gm/T Au Across 1.3m, within an IOCG Zone Averaging 3.03% Cu Over 17.0m

CALGARY, ALBERTA--(CCNMatthews - July 18, 2005) - Trio Gold Corp. (TSX VENTURE:TGK) (PINK SHEETS:TROOF)

Trio has completed a 15-hole, 2477 m, Phase I drill program on its 35 km2 San Ramon property located 45 km west of Copiapo, Chile. Trio's drill results confirm the discovery of IOCG mineralization with high-grade copper intercepts on the San Ramon property. Results from 9 of the 15 holes were released on June 13th, 2005. Results from the last 6 holes have been received from ALS Chemex, La Serena, Chile. These six holes were drilled on the San Ramon (holes #12, 13, 14), Paulina (#8, 9) and Lorenzo (#15) structures. A report on Phase I drill results will soon be available on Trio's website.

A grade of 1.00% Cu corresponds to 20lb /ton, 10kg/Tonne copper.

San Ramon is located 55km northwest of Phelps Dodge's Candelaria Mine which is one of the largest Iron-Oxide-Copper-Gold (IOCG) deposits in Chile, hosting 470MT grading 0.95% Cu and 0.2 gm/T Au.

All holes drilled at San Ramon penetrated mineralized hematitic-potassic alteration characteristic of IOCG mineralization. The Carmen structure is an IOCG-mineralized shear zone traced by drilling for a distance of 600m, a true width of 26m, a depth of 170m, and a weighted average grade of 0.56% Cu and 0.45 gm/T Au. Within this is a 330m long, 18m wide zone grading 0.97% Cu and 0.62 gm/T Au. The IOCG mineralization is open at depth and on strike.

The Carmen shear includes a high-grade breccia, which is 270m long, 2.9m in true width, and grades 3.83% Cu, 1.49 gm/T Au and 0.08% Co. This includes intercepts as high as 19.4% Cu across 1.0m true and 5.4% over 4.6m true. This zone is open at depth.

The San Ramon, Paulina and Lorenzo structures splay off the Carmen shear. They are similarly altered, with grades reaching up to 3.03% Cu and 0.51 gm/T Au across 17.0m (incl. 5.4m grading 8.48% Cu).

Management believes that these results warrant further drilling at depth and on strike. Trio's drilling was concentrated on exposed mineralization located between two large sand-covered chargeability anomalies. These anomalies, which are 2,900m x 1,000m and 800m x 800m in size, may represent buried IOCG mineralization, and it is Trio's intent to drill-test these large anomalies.
