The Company has consolidated the current management leadership to streamline and focus on the critical exploration work coming ahead as the Company gears up its Mexico exploration efforts.

Dr. Shane Ebert, Ph.D., PGeo., currently a Director of Tyler, has been appointed Vice-President of Exploration. With Dr. Ebert's hands-on knowledge of the Bahuerachi property and his wide industry experience, this appointment significantly strengthens the management team.

In other Corporate Developments, the Company is pleased to announce receipt of notice that it has been selected and has now been included in the Liberty Funds Liberty Micro-Cap Resources Index. This endorsement is a most welcome development which will allow the Company further opportunities to increase its presence and visibility to the investment community as it continues to explore for copper, gold, silver, zinc and molybdenum in Mexico.

Field Update

Drilling is ongoing on the project with two diamond drill rigs. The third rig is being mobilized to site and is expected to commence drilling in early December. Since the last update (NR 05-28, Nov. 2), two more drill holes have been completed and drilling is currently ongoing with drill holes #50 and 51. Drill hole #50 is currently testing a wide (approximately 400 meter) zone of mineralized porphyry approximately 150 meters North of section 2NE. This drill hole is designed, as part of a 3 drill hole fence, to test one of the widest areas of mineralization as outlined by surface mapping and sampling to date and will aim to demonstrate clear bulk tonnage potential for the Bahuerachi Main Zone. Drill hole #51 is the first drill hole testing a porphyry area south of the main drilling area (South porphyry/Goat Zone). Results from the drilling will continue to be released in batches as the project advances.
