Silver Grail & Teuton Identify Large Silver Target On Tonga

Silver Grail Resources Ltd. (“Silver Grail”) and Teuton Resources Corp. (“Teuton”) have identified a large, attractive silver target on their jointly owned Tonga property by integrating results from a recently completed, Aeroquest EM and Magnetometer survey with all prior work completed on the project. This 40 square kilometer property is located in the southern portion of the prolific Stewart-Eskay Creek silver-gold camp, just west of the Kitsault River silver mining district.

Anomalous geophysical responses obtained during the survey have outlined a primary target area measuring 800 by 1,800 meters. This area overlaps and extends a previously defined target marked by soil, stream and talus fine geochemical samples, many of which were highly anomalous in silver. The source of the anomalous geochemical and geophysical responses remains unknown, but based on data in hand may arise from mineralized sedimentary exhalative horizons underlying the target area.

Approximately 1 km to the south, two strong, discrete EM anomalies were also detected.These anomalies are parallel to, and lie within, a magnetic low trending at right angles to the strike of geological units on the property.

Company geologists, in collaboration with Aeroquest’s geophysicists, will be selecting priority targets for drilling on the Tonga in 2006.

Dino Cremonese, P.Eng., president and CEO of Silver Grail and Teuton, stated: “The Aeroquest geophysical survey has materially enhanced our understanding of the Tonga property and its potential for hosting mineral deposits. We look forward to drill testing these exciting targets in the summer months”.

Silver Grail and Teuton have also recently completed Aeroquest surveys on their Silver Bell, Bay Silver, Silver Crown, Silver Cloud, Bud and Ram properties, all situated within the Stewart-Eskay camp. Also complete is a survey over the Clone gold property, currently under option to Canasia Industries Ltd. Results from these surveys are expected within the forthcoming weeks.

K. Mastalerz, Ph.D., is the Qualified Person in charge of the 2006 program on the Tonga property.
