Alto Ventures News Release 8000m of Drilling Commences on the Coldstream Property, Ontario Vancouver B.C., June 10th, 2010: Alto Ventures Ltd.

(ATV: TSX-V) is pleased to announce the start of a minimum 8,000m diamond drilling program on the Coldstream Property in Ontario.

The main objective of the current diamond drilling program is to further define and expand the East Coldstream deposit.

Drilling is also planned in the Span Lake area to confirm gold-bearing zones drilled by Inco in the 1980s and to test the potential continuity of the Moss Lake gold deposit (NI 43-101 compliant inferred resource of 1.5 million ounces contained gold) on to the southern-most claims in the Span Lake area of the property.

The program is being carried out by Foundation Resources Inc (FDN: TSX-V) who is the Project Operator and is funding this exploration program to earn an interest in the project. About the East Coldstream Deposit The East Coldstream Gold Deposit, with historically reported resources of 5.1 million tonnes averaging 1.4 g/t 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 a "qualified person" (as that term is defined in NI 43-101) has not 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.

Gold mineralization starts on surface and this resource estimate was based on relatively shallow drilling at 3 zones (the Main, North, and East zones).

The historical resource does not include the gold mineralization at the Sanders Zone which was drilled by Lacana Mining Corp.

(1989) and Alto Ventures Ltd.

(2006).

The Sanders Zone is located northeast of the Main Zone and south of the East Zone. About the Coldstream Project The Coldstream Property includes 5,394 hectares of staked and patented mining claims along the Trans Canada Highway 115 km west of the City of Thunder Bay, Ontario.

The area is road accessible and has excellent infrastructure with a major power line and CN rail line passing just north of the property.

Skilled labour is readily available locally. The property is under an Option Agreement with Foundation Resources Inc.

Foundation is the operator and is funding the current exploration program to earn an initial 60% interest.

Foundation then has the option to earn an addition 10% interest.
