Mud Lake Project, Ontario
Highlights
- Gold mineralization discovered along 6 km shear zone
- Twelve gold occurrences identified by trenching, some of the better assays from grab samples include
30.0 g/t gold from Showing #1
50.6 g/t gold from Oliver Severn Showing
19.8 g/t gold from Showing #6
8.1 g/t gold from Clarke Showing
- Drilling in 2007 intersected up to 13.9 g/t gold across 1.0 m within 6.1 m wide mineralized zone averaging 3.3 g/t gold
- A 16.9 line-km Induced Polarization survey outlined 20 anomalies that could be related to mineralization
- An 18 hole program was completed in January 2008; assays are pending
Location and Access
- Elmhirst Township, approximately 25 km northeast of Beardmore, Ontario
- North of the Brookbank Property owned by Ontex Resources and south of the Hercules Property operated by Kodiak Exploration
- Access by Secondary Provincial Highway Number 801 and old logging roads
Geology
- 6 km long shear zone (Mud Lake Shear) cutting through Archean age Coyle Lake felsic intrusive
- Alteration of sheared rock includes sericite, carbonate, silica, chlorite, pyrite, magnetite and hematite
- Gold mineralization is associated with quartz and quartz-carbonate veins that occur as shear-parallel en-echelon veins, gold also occurs associated with pyrite stringers and quartz-microveins within the shear

History
The Beardmore-Geraldton Gold Belt has historically produced over 4.1 million ounces of gold. Exploration work on the property dates back to the 1930's and consisted of mainly prospecting, ground geophysical surveying and trenching. In the late 1980's Noranda Exploration carried out an extensive program of geological mapping and trenching. Frank Houghton, a Beardmore prospector continued to prospect and trench the area until 2004 when Alto Ventures entered into an Option to Purchase Agreement with Houghton.
Alto carried out geological mapping in 2005 to better understand the distribution of the gold occurrences and controls on gold mineralization. The Company also completed line cutting and 16.9 km of Induced Polarization surveying. The geological work has confirmed the presence of 12 gold occurrences along the 6 km Mud lake Shear Zone and recognized that gold is associated with quartz and quartz carbonate veins as well as pyrite stringers within shear zones in areas where quartz veining is not abundant. The IP work has identified 20 anomalies that could be related to sulphide (pyrite) mineralization and possibly gold that is associated with the sulphides.
In February, 2007 Alto drilled 12 holes totaling 753 m to test three (Clarke, Oliver Severn and Showing #6) of the 12 showings.
A fall exploration program included trenching, sampling and diamond drilling. Diamond drilling started in late November and was completed in late January, 2008. In total, 18 holes were completed to test three of the showings not drilled before (No. 3 Showing, No. 4 Showing, and No. 5 Showing) and follow up mineralization intersected in drill holes completed during the 2007 winter program. Significant assay results obtained from the 2007 winter program and those completed in December are presented below; results from holes completed in January 2008 are pending.

2008 Exploration Programs
Additional drilling will be carried out in 2008 to test the remaining surface gold occurrences not yet drilled as well as follow-up on results from the 2007 drill programs.
