Alto Ventures Ltd.: Summer Program Started at Miner Lake, Beardmore-Geraldton Gold Belt, Ontario

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 23, 2011) - Alto Ventures Ltd. (TSX VENTURE:ATV) is pleased to announce that its summer exploration program has started at Miner Lake in the Beardmore-Geraldton Gold Belt. The objective of this surface work is to better define targets for a diamond drilling program scheduled to start in July. The surface work includes geological mapping, outcrop washing and saw-cut channel sampling.

Mike Koziol, President & Director of Alto, states, "Exploring the Miner Lake property has been very exciting. The recognition that gold occurs in wide sulphide-bearing shear zones and breccias rather than in narrow quartz vein settings is encouraging as this style of mineralization is favourable for the formation of large deposits. We are looking forward with great anticipation to the drilling program that will follow in July."

Gold mineralization at Miner Lake is associated with extensive zones of shearing and areas of hydrothermally altered breccias in a quartz-diorite to a diorite intrusive plug and the surrounding volcanic rocks. Pervasive sulphide mineralization of pyrrhotite, pyrite and chalcopyrite occurs throughout the intrusive, including some zones of mineralization that exceed 60 m in width. Surface sampling by Alto in 2009 and 2010 has confirmed the widespread distribution of gold including wide zones up to 19 m averaging 1.78 g/t gold and 0.11% copper in saw cut channels and up to 25.2 g/t gold in grab samples (see Alto News Release dated May 26, 2010). The size potential of the shear and breccia zones is not yet known but the intrusive body that hosts the gold has surface dimensions of 2.5 km by 1km and gold mineralization has been found at numerous locations within the intrusive, and recently near its boundaries (to see figure please click on: http://media3.marketwire.com/docs/atv623.pdf).

The Miner Lake property had been subject to sporadic exploration work prior to Alto's 2010 program and the areas of gold mineralization have not been drilled previously. The property is located only 50 road kilometres from the Town of Beardmore and is easily accessible to drilling and other exploration work all year-round.
