Further High Grade Results at Alto's Despinassy Gold Deposit

 Vancouver, B.C. May 31, 2006. Rick Mazur, President & CEO of Alto Ventures Ltd. (ATV: TSX-V) is pleased to announce that the Company and Commander Resources Ltd. (CMD: TSX-V) have continued to receive further high grade results from the recently completed, Phase Two drill program at the Despinassy gold project near Val d'Or, Quebec. Significant gold mineralization has been intercepted in the final six holes as extensions of multiple veins along strike or down plunge within the DAC deposit.

An independent evaluation by Hubacheck Consulting Geologists following Alto's Phase One drill program (see news release dated November 28, 2005), indicated that the DAC deposit may contain between 303,000 and 670,000 tonnes grading 6.8 to 7.8 grams gold per tonne (g/t). The Phase Two drill program was designed to enhance the definition of the mineral resource at the DAC deposit to be compliant with NI 43-101 standards. A summary of all results and further development plans for Despinassy will be reported following integration of the current drill information with past data.

The Phase Two drill program, comprising 5,106 metres (m) in nineteen holes has significantly extended the area of gold mineralization within the DAC Zone and confirms continuity and grade of the individual veins. Assays from the final drill holes include gold intercepts of 14.3 g/t over 2.1 m, 19.5 g/t over 0.7 m and 13.2 g/t over 1.0 m within wide, lower grade alteration envelopes containing grades up to 2.3 g/t over 8.0 m and 0.9 g/t over 27.9 m.

Principal results for Holes DES 06-97 to 102 are summarized as follows:

Due to the angles of intersection of the zones by the drill holes, the approximate true thickness of the mineralized veins is estimated to range from 80% to 90% of reported down-hole intercepts. For results in previous holes see news releases dated February 27, March 20, March 29, and April 12, 2006.

Quality Assurance/Quality Control

Core processing included descriptive logging and selection of samples for analyses. The drill core 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. Sieve metallic assays are performed as required.

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.

The Despinassy Gold Project is a joint venture between Alto Ventures Ltd. (70%), as operator and Commander Resources Ltd. (30%). Robert J. Tremblay P.Geo (Quebec) supervised the drill program. Mike Koziol, P.Geo, P.Eng and Alto's Vice President, Exploration is the Company's Qualified Person and has reviewed and approved the content of this release.
