Tyler posts new number for Bahuerachi (May 23, 2007)

Nine months’ drilling by Tyler Resources (TYS-V) has succeeded in increasing the resource estimate on the Bahuerachi copper project in Chihuahua state, Mexico, about three times over.

Consulting firm Associated Geosciences puts the size of the measured and indicated resource at 525 million tonnes at grades of 0.4% copper, 0.55% zinc, 0.008% molybdenum, 4 grams silver and 0.03 gram gold per tonne, based on a 0.2% copper cutoff grade. Last year, Associated had estimated an indicated resource, using drill data up to July 2006,at 135 million tonnes grading 0.49% copper, 0.08% zinc, 0.009% molybdenum, 4.3 grams silver and 0.05 gram gold per tonne.

The new resource reflects additional drilling in skarn zones around the porphyry body, where zinc is the primary metal; the contained zinc in the resource has increased by about twenty-fold. The main copper porphyry and skarn zones have also been expanded.

Tyler has engaged a consultant for pit designs and is preparing a preliminary economic analysis of the project.
