HIGHLIGHTS

-- 3.07 g/t gold over 13.9 m within a 34.5 metre-wide zone averaging 1.93 g/t gold -- 4.26 g/t gold over 4.8 m within a 26.15 metre-wide zone averaging 1.09 g/t gold -- 5.47 g/t gold over 6.9 m within a 13.0 metre-wide zone averaging 3.06 g/t gold

Alto Ventures Ltd. is pleased to announce the results from the first three drill holes of the 8,000 m drill program on the East Coldstream Gold Deposit ("Deposit") located at the Coldstream Property in Ontario. The work 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 Coldstream Property.

The current 8,000 m drill program is designed to follow up on the positive results obtained from the 2010 winter drilling, increase confidence in the continuity of gold mineralization within the Deposit and to expand the existing, non-NI 43-101 compliant, historical resource. Each of the current three holes (C-10-23, C-10-24 and C-10-25) intersected wide sections of gold mineralization in both the Main and North zones; these zones lie parallel to each other and are located less than 100 metres apart. The Main and North zones were also drilled during the 2010 winter program and wide intercepts of gold mineralization, including sections with high grade gold values were reported by Alto on March 29, April 6, and April 21 2010. Gold in both zones is associated with pyrite and occurs within strongly sheared and hydrothermally altered (silica, albite, sericite, magnetite and hematite) areas of mafic to intermediate metavolcanics and quartz-feldspar porphyry intrusive rocks.

Drill hole C-10-23 was drilled at 160 degrees/-53 degrees to a depth of 267.31 metres, C-10-24 drilled at 337 degrees/-48 degrees to a depth of 252.07 metres, and C-10-25 was drilled at 334 degrees/-50 degrees to a depth of 288.65 metres. All intervals are represented as down hole core lengths, with the true widths estimated between 70-75 percent of core length.

Quality Assurance and Quality Control

Drill core processing included descriptive logging and selection of samples for geochemical analyses. The NQ2-size core was cut in two halves using a stationary rock saw at the field camp in Kashabowie, Ontario. One-half of the core was delivered to the sample preparation lab of ALS Chemex Laboratory in Thunder Bay where they were crushed and a 1000-gram pulp was prepared. The pulp was then shipped to ALS Chemex Laboratory in North Vancouver, B.C. for analyses. The gold assaying method uses a standard Fire Assay with ICP-AES technique on a 30-gram pulp material taken from a 1000g split from the submitted sample. Any sample that exceeded upper detection limit of 10 ppm or grams was re-analyzed by the same Fire Assay method but with gravimetric finish. Commercially prepared standards and blanks were inserted by Foundation every 20 samples to insure precision of the results. ALS Chemex inserted its own standards, blanks and carried out duplicate analyses on sample pulps to ensure internal lab quality control. For regular Fire Assay technique with an ICP-AES finish, the lab inserted 1 blank at the beginning, 2 standards at random intervals, and 3 duplicates were analyzed at the end of the batch of every 84 samples. For the Fire Assay method with gravimetric finish, inserting 1 blank, 2 standards, and 1 duplicate followed the same procedure on a batch of every 20 samples.

About the East Coldstream Deposit:

The 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 and was further tested by one hole (C-10-22) during the 2010 winter program. Hole C-10-22 intersected 27.46 m wide zone averaging 1.16 g/t gold, including 10.05 g/t gold over 2.1 m.

The Moss Lake gold deposit (NI 43-101 compliant inferred resource of 1.5 million ounces contained gold) adjoins the southwest end of the Coldstream Property.

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%.
