Gold Intersected At Greenoaks, Beardmore-Geraldton Area
======================================================================
Vancouver, B.C., April 3, 2007. Alto Ventures Ltd. (ATV: TSX-V) 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 0.8m.
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
1960s, 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.
Table of Significant Results from Greenoaks
Hole From (m) To (m) Width (m) Au (g/t) Zone
GRN07-01 13.2 13.6 0.4 12.5 Zone 1, Visible Gold
GRN07-04 12.0 12.5 0.5 2.1 Zone 4, Visible Gold
GRN07-04 21.9 22.7 0.8 7.08 Zone 3, Visible Gold
GRN07-05 61.8 63.0 1.2 0.11 Zone 1, deepest
mineralized 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.
Table of Significant Results from Cote-Archie Lake
Hole From (m) To (m) Width (m) Au (g/t) Zone
COT07-01 70.6 76.6 6.0 0.35 Cote Shear
includes 74.6 75.6 1.0 1.13 Quartz vein
80.6 89.0 8.4 0.5 Cote Shear
includes 80.6 83.0 2.4 1.35 Quartz vein
COT07-02 19.1 22.0 2.9 0.52 Weak shearing in front
of Cote Shear
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/1.0m 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.
