Drill hole YO-07-05, targeting the El Indio System, collared into a previously unrecognized zone of silver-gold mineralization including a 0.50 metre interval which returned 2.08 g/t gold and 345 g/t silver. The El Indio vein system was intersected over a width of 4.10 metres, at a down hole depth of 24.60 metres, and is cored by an interval which returned 2.66 g/t gold and 267 g/t silver over 1.15 metres. Eight holes totalling 2,474 metres were completed during the Phase 1 drill program.

The Yoquivo Project covers the entirety of the historic Yoquivo Mining District and is located 40 kilometres southeast of Agnico-Eagle's Pinos Altos gold-silver development project in the heart of the Sierra Madre Belt. Historically reported production grades from the San Francisco mine on the Yoquivo Project averaged 10.90 g/t gold and 1,120 g/t silver.

West Timmins Mining is the operator of the Yoquivo Project. Subject to an Option Agreement dated May 31, 2006 Gold Mountain may earn an initial 50% interest in the Yoquivo Project by making cash payments of US $200,000, issuing 1,000,000 common shares to West Timmins, funding US $1,000,000 in exploration expenditures on the Project over a 24 month period and making all cash payments required by West Timmins to the underlying property vendor.

Quality Control and Assurance

Geochemical results reported herein are from halved drill core samples collected from the Company's Yoquivo Project. Core sampling is conducted on site by trained personnel and sealed samples are transported to ALS-Chemex's preparation facilities in Chihuahua, Mexico by employees of consulting firm Minera Cascabel S.A. de C. V. on behalf of West Timmins Mining Inc. The remaining half of the drill core is stored in a secure facility on the project site.

All samples were assayed for gold by standard fire assay-ICP finish with a 50 gram charge. Samples additionally underwent 34 element ICP-MS analysis. Gold values in excess of 3.00 g/t were re-analyzed by fire assay with gravimetric finish for greater accuracy. Silver, zinc, copper and lead values in excess of 100 ppm, 1%, 1% and 1% respectively were also repeated by fire assay. For quality control purposes blank and analytical control standards were inserted into the sample sequence at regular intervals - no discrepancies are reported. Mr. Darin Wagner (M.Sc., P.Geo.), the Company's President, has acted as non-independent qualified person for this news release. The qualified person has not independently verified the drill results.
