Despinassy Gold Project, Val D'Or, Quebec - Phase One Drill Results

 Vancouver, BC, May 25, 2005. Alto Ventures Ltd (ATV: TSX-V) has completed the 2005 Despinassy drill program and is pleased to announce the results of the final two holes drilled on the DAC deposit. Infill drilling at DAC has confirmed the continuity of the gold mineralized zones for 100 metres(m) along strike and to a depth of 250 m at a 25 m drill spacing. Detailed results from the infill drilling program can be reviewed in Alto news releases dated February 16, 2005 and April 14, 2005. The final two holes are step-out holes on the DAC deposit along strike and at depth. DES05-82 intersected the mineralized zones for another 150 m to the west of the DAC deposit. Hole DES05-83, a step-out hole at 460 m depth, confirmed the continuity of the gold mineralized zones between prior intercepts of gold mineralization by Cameco Corporation at 300 m and 600 m depths. With these step-out holes, drilling at DAC has confirmed continuity of the mineralized zones for up to 250 metres along strike and to 600 metres depth.

The Despinassy gold project is located 75 kilometres(km) northeast of Val d'Or, Quebec. The Company is delineating gold mineralization along the Despinassy Shear Zone, a district scale, east-west trending structural break parallel to and 75 km north of the Cadillac-Larder Lake Break. This region has produced in excess of 90 million ounces of gold in prolific gold camps such as Val d'Or, Malartic, and Kirkland Lake. The results from these step-out drillholes are as follows:

This hole was collared on line 500W (150m west of the DAC deposit).

Earlier work by Cameco inferred, and Alto's drilling confirmed, that the best gold occurrences are in areas of folding. Since there are no bedrock outcrops nearby, the infill drilling has provided the necessary data to begin interpretation of the structural trends to determine plunge directions to the high-grade gold shoots. Re-logging of core from previous Cameco drilling and a compilation of all drill data is underway to gain this interpretation. Management is currently reviewing all of the drill data and will provide a summary of the entire Despinassy program upon completion of their review.

Quality Assurance/Quality Control

Core processing included descriptive logging and selection of samples for analyses. The cores selected for analyses were sawed in half and one half was delivered to a commercial laboratory and the other half retained for future reference. Gold assays were performed at ALS Chemex Laboratories in Val d'Or, Quebec. The gold assaying method uses a standard Fire Assay with AA or Gravimetric finish technique, as requested by the Company, on a 30 gram sub-sample taken from a 250 gram split of the sample submitted.

The laboratory was instructed to prepare and analyze a second 250 gram split from the reject for those samples that indicated greater than 2 g/t Au on the initial analysis. The results reported represent composites using weighted averages of all analyses performed on each specific sample. Commercially prepared standards were inserted every 25 samples to ensure precision of the results. Mike Koziol P.Geo., Alto's Vice President of Exploration, is the designated qualified person and Robert J. Tremblay, P.Geo. (Quebec) supervised the diamond drilling at Despinassy.
