Vancouver B.C. December 1, 2009: Alto Ventures Ltd. (ATV: TSX-V) is pleased to announce results of the summer field work at the Iris Zone on the Coldstream Gold Property, Ontario. The 2009 field program on the Coldstream Property was focused on generating new high quality drill targets and gaining a better understanding of the controls on mineralization.

The strong similarities to the East Coldstream Deposit, the kilometre-long IP chargeability anomalies and positive results from the very limited past drilling demonstrate the highly prospective nature of the Iris Zone. Drilling in being planned to test the new zone in this under explored area of the Coldstream Property.

Highlights of the Iris Zone:

-2009 grab samples returned up to 15.8 g/t Au

-Recently acquired claims expand the Coldstream Property northward to cover this highly prospective ground

-Mineralization shows strong similarities to the East Coldstream Deposit, located only 1.5 km to the south (non 43-101 compliant resource of 5.1 million tonnes with 234,000 ounces contained gold)

-Mineralization is associated with IP Chargeability anomalies

-Very limited drilling was completed previously with encouraging results including:

Drill Hole   From (m)   To (m)   Length (m)   Au g/t   
VAN-07-003   53.3       58.5     5.2          1.27     
VAN-07-003   65.1       70.1     5            1.28     
VAN-07-005   25.5       38       12.5         0.74     
includes     33         37       4            1.19     

The Iris Zone occurs at the northeast end of the Coldstream Property on claims that were added to the property this summer. The exploration work was completed by Foundation Resources Inc (FDN: TSX-V) which is earning an interest in the project and is the operator of the project. The Iris Zone is located only 1.5 km north of the East Coldstream Deposit.

Claims including the highly prospective Iris Zone were added to the Coldstream Property during the summer of 2009 (see Alto news release dated July 23, 2009) and a preliminary field assessment including prospecting and sampling of this new ground was carried out subsequently. Five IP chargeability anomalies have been delineated at the Iris Zone in 2007; two of these anomalies extend over 1 kilometre in strike length.

.History

The East Coldstream Deposit, with historical resources of 5.1 million tonnes averaging 1.4 g/t gold and containing 234,000 ounces of gold, was discovered by Noranda Exploration Ltd and was delineated by 37 diamond drill holes between 1988 and 1991. Noranda prepared the historical resource estimate in 1991 however no "qualified person" (as that term is defined in NI 43-101) has to date done sufficient work to classify the historical estimate as current mineral resources. The Company is not treating the historical estimate as current mineral resources (as defined in NI 43-101) and thus the historical estimate should not be replied upon. Please see Alto's November 16th news release for further details on the East Coldstream Deposit

Very limited drilling has been completed at the Iris Zone. Drilling completed in 2007 by Trillium North Minerals Ltd targeted IP chargeability anomalies trending sub-parallel to anomalies coincident with the East Coldstream Deposit. Each of the two one-kilometre long IP chargeability anomalies has been tested with only a single drill hole. VAN-07-003 was completed in the southern anomaly and returned 5.2 metres grading 1.27 g/t Au and 5 metres grading 1.28 g/t Au. VAN-07-005 tested the northern anomaly and returned 12.5 metres grading 0.74 g/t Au, including 1.19 g/t Au over 4 metres. These very positive results have not yet been followed up with additional drilling.

Quality Control

Grab samples of rock from outcrops were collected and were described in the field by Geologists from Coast Mountain Geological ("CMG"), the contractor for Foundation, as to rock types, mineralization and then bagged and brought to the

campsite where blanks and standards were inserted after every 25 sample series. The bagged samples were then placed into large rice bags and marked for delivery to the assay lab for analyses of gold and other selected elements. The staff of the CMG delivered the samples to certified ALS Laboratory (ISO 9001:2000 and ISO 17025:2005) in Thunder Bay, Ontario. The samples were weighed, crushed (70% - <2mm), pulverized (split to better than 85% passing 75 microns), and then analyzed for gold and other trace elements by the lab. Gold is analyzed by the lab for up to 10ppm upper detection limit using the fire assay procedure on a 30g sample with ICP finish. Any sample exceeding this upper limit value was then re-analyzed by the same fire assay method but with gravimetric finish.
