Alto Confirms High Grade Gold Trend Over 2 km at 100% Owned Oxford Lake Property, Manitoba
Vancouver, B.C., May 8, 2012. Alto Ventures Ltd. (ATV: TSX-V) is pleased to announce the results from six diamond drill holes that were completed in 2012 on its 100% owned Oxford Lake property located in central Manitoba.
- 22.5 g/t gold over 0.5 m, 16.5 g/t gold over 1.0m and 11.7 g/t gold over 1.6 m intersected approximately 2 km east of the Rusty Zone
- Drilling also confirms gold mineralization at the Rusty Zone which hosts Historical Resources* of 800,000 tonnes averaging 6 g/t gold, containing approximately 154,000 ounces of gold
- Property is interpreted to lie along a major regional structural corridor that hosts the Monument Bay Gold Deposit operated by Mega Precious Metals
Drill hole RUS12-03 intersected two zones of high-grade gold mineralization:
Drill hole RUS12-03 was drilled 2.2 km east along strike from the Rusty Zone to test the historical Blue Jay Zone. This hole intersected better gold values than the historical drilling (up to 10 g/t over 2.0m) and encountered multiple zones of gold mineralization (Table 1). The mineralization is open at depth and potential for further deposits occurs along a 30 km trend of aeromagnetic "Highs" that are under-explored on Alto's 30,000 hectare property.
- Zone One - 2.7 m averaging 6.7 g/t gold including 22.5 g/t gold over 0.5 m
- Zone Two - 6.8 m averaging 5.7 g/t gold including 11.7 g/t gold over 1.6 m and 16.5 g/t gold over 1.0 m.
Drill holes RUS12-01 and 02 were drilled at shallow depths to confirm the ground location of the historical Rusty Gold Zone (Historical Resources* of 800,000 tonnes averaging 6 g/t gold to a depth of 600 metres) and to obtain samples of the mineralization as cores from the 1980's drilling are not readily available. The two holes were spaced 200 m apart on strike and each intersected the mineralized zones at their predicted locations (Table 1).
Results from drilling at Oxford Lake are most encouraging confirming gold mineralization for over 2 km along strike and the potential for high gold grades along this trend. The Rusty trend was traced by Alto's 2011 VTEM and aeromagnetic surveys for 30 km along strike but only a few holes were drilled in the past along this trend.

**The widths reported are down-hole lengths as there is insufficient drilling density to determine the true widths. Mineralized zones generally start at 0.1 g/t gold and assay averages may include minimal intervals of waste material. No top cuts of assays were used.
Drill Holes OMA12-01 to 03 tested airborne electromagnetic (VTEM) conductors associated with aeromagnetic "Highs" at the south end of the property. These conductors occur in a separate, east trending band that is located approximately three kilometres to the south of the Rusty Gold Zone. Each of the drill holes intersected iron formation and sulphides and drill hole OMA12-03 returned anomalous gold of 1.75 g/t gold over 1.15m. Results from the OMA holes indicate that this second trend also has potential to host significant gold mineralization.
In total, Alto drilled 1,029 m in six holes in 2012 during a rather difficult warm winter drill season. Pre-drilling preparation work consisted of 100 line kilometres of line cutting followed by Max Min HLEM and ground magnetometer surveying that was completed in February, 2012.
About the Rusty Gold Zone Deposit
The Rusty Gold Zone hosts a Historical Resource* of 800,000 tonnes at an average grade of 6 g/t and contains approximately 154,000 of gold. The mineralization was drilled to a depth of 600 metres by Noranda and is open along strike and to depth. The resource was estimated in 1990 and a Qualified Person (QP), as defined by NI43-101, has not done sufficient work to classify this historical estimate as current mineral resources. Alto is not treating the historical estimate as current mineral resources, as defined by NI43-101, and thus the historical estimate should not be relied upon. The Rusty Gold Zone is associated with a banded iron formation (BIF) and is one of several significant gold occurrences associated with a regional trend of aeromagnetic "High" anomalies. This aeromagnetic trend, which extends for 30 km in the northern half of Alto's Oxford Lake property, is interpreted to be the geophysical signature of the BIF that hosts gold mineralization.
About the Oxford Lake Project
The 30,000 ha Oxford Lake gold property is located in central Manitoba, approximately 150 km southeast of Thompson. Geologically, the property lies in the Oxford Lake-Knee Lake greenstone belt near the west end of the Superior Province of the Canadian Shield. The Western Superior has proven potential for hosting large gold deposits, including the Musselwhite Mine with past production and reserves of over 5.7 million ounces of gold hosted in a BIF. The Oxford Lake property lies along a major regional structural corridor that hosts the pre-development Monument Bay Gold Deposit near the eastern end of this corridor. The Monument Bay Deposit hosts reported resources of 1.04 million ounces of gold in the Indicated and Measured categories plus 1.72 million ounces in the Inferred category (see Mega Precious Metals Inc website) and is located approximately 150 km east of the Oxford Lake project. This corridor is relatively under-explored and could be an early stage analogue to the large gold-producing Destor-Porcupine or Larder-Cadillac corridors in Ontario and Quebec.
Quality Assurance/ Quality Control
Core processing included descriptive logging and selection of samples for analyses. The BTW-size cores were sawed in half and one half was delivered to a commercial laboratory. The samples were delivered to the SGS Mineral Services laboratory in Red Lake, Ontario where they were crushed and a 250 gram pulp was prepared. The pulp was then assayed for gold. The gold assaying method uses a standard Fire Assay with AAS finish technique on a 30 gram aliquot taken from the 250 gm pulp. Commercially prepared standards were inserted by Alto at predetermined intervals to ensure precision of the results. The laboratory performs routine repeat check assays on pulps of selected samples to ensure internal lab quality control.
The laboratory was instructed to prepare and analyze a second 250 gram pulp from the reject for those samples that indicated gold values of greater than 1 g/t on the initial analysis. The gold assaying method on the re-split uses a standard Fire Assay with Gravimetric finish technique on a 30 gram aliquot.
