Alto Ventures Ltd.: Gold Intersected at Greenoaks, Beardmore-Geraldton Area

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 3, 2007) - Alto Ventures Ltd. (TSV VENTURE:ATV) is pleased to announce results from the 2007 drilling on the Greenoaks and Cote-Archie Lake projects in the Beardmore-Geraldton Gold Belt. The Beardmore-Geraldton Gold Belt is renowned for its high grades averaging almost 0.4 oz/ton (13.7 g/t) gold from historical production which has exceeded four million ounces. The Greenoaks project is located seven kilometres northwest of the Company's Mud Lake property where drilling earlier this year intersected prominent shear structures carrying significant gold (see Alto News releases dated March 6 and March 20, 2007).

Greenoaks Project

Five holes, totalling 331 metres (m) were completed at Greenoaks in 2007. Two of the five holes intersected visible gold with assays including 12.5 g/t gold across 0.4 m and 7.08 g/t gold across 0.8 m. Historical surface work resulted in the discovery of four zones along a 400 m segment of a west-northwest trending shear where gold-bearing quartz veins have been emplaced. Previous drilling, dating back to the 1960's, focused only on Zone 1 and intersected high grade gold mineralization including 1.2 ounces per ton (41 g/t) gold across 5 feet (1.5 m). Zones 3 and 4 were not drilled prior to this program.

The 2007 drilling has confirmed the mineralization in Zone 1 and indicates that more drilling is required to evaluate Zone 1 as well as Zones 3 and 4. The results presented in the table below are very encouraging.

GRN07-05 61.8 63.0 1.2 0.11 Zone 1, deepest

intersection on the
property
---------------------------------------------------------------------------


Hole GRN07-05 intersected Zone 1 at 50 m vertical depth and this is the deepest test of this zone. The zone was intersected from 61.8 m to 63.0 m downhole and it consists of solid quartz vein containing 5% sulphide minerals including pyrrhotite and chalcopyrite. The vein is visually impressive but since no visible gold was observed in the drill core, the gold assays are lower.

Cote-Archie Lake Project

The project is located 5 km north of the Town of Beardmore and is road accessible year-round. Previous work by Alto has identified a new major shear structure (Cote Shear) with gold mineralization at several locations along the shear, locally up to 11.2 g/t across one metre chip samples. The Cote Shear trends parallel to the shear that is host to the gold-bearing quartz veins mined at the former Leitch Mine which is located 5 kilometres southwest of Alto's property. The Leitch Mine was one of Canada's highest-grade gold mines and produced 860,000 ounces of gold at a grade of 0.92 ounces per ton prior to closing in 1968.

Drilling of two holes was attempted but only one was completed and the other was terminated before reaching its target. COT07-01 was drilled to test the Cote Shear and it intersected the target, a well developed and altered shear zone that is twenty metres wide and contains variable quartz veining including a 2.4 m wide quartz vein/vein breccia that contains minor amounts of sulphides. Although the assay results obtained from this first hole are not economic, the intersection of strongly sheared rocks that contain auriferous quartz veins is very encouraging for a first-pass drill program (please see table below).

Hole COT07-02 attempted to test the same structure as COT07-01 but 50 m west along strike. The hole was terminated at 44 metres and well short of its target due to logistical problems related to water shortages caused by the very cold snap during the drilling of this hole. A weakly developed shear with 1 to 3% sulphides was intersected halfway down the hole and it too contains anomalous gold.

Summary

Nineteen holes totalling 1,245 m were drilled on Alto's three projects in the Beardmore-Geraldton area in 2007. The drilling tested new targets and in addition to intersecting gold-bearing quartz veins within major shear zones, encouraging assay results were received from each of the projects including high grade values at Mud Lake (13.9 g/t gold/1.0 m within a wider zone containing 3.39 g/t gold/6.1 m) and at Greenoaks (12.5 g/t gold/0.4 m and 7.08 g/t gold/0.8 m). Additional work is planned for the summer months and will include trenching and mapping then followed by diamond drilling.

Quality Assurance/ Quality Control

Core processing included descriptive logging and selection of samples for analyses. The NQ-size cores selected for analyses were sawed in half and one half was delivered to a commercial laboratory by Alto staff for analyses and the other half retained for future reference. Gold assays were performed at Accurassay Laboratories in Thunder Bay, Ontario. The gold assaying method uses a standard Fire Assay with AA finish technique on a 30 gram sub-sample taken from a 500 gram split from the submitted sample. Commercially prepared standards were inserted by Alto every 25 samples to ensure precision of the results. The laboratory ran internal check assays every 10 samples to ensure lab quality control.
