Gold Intersected At Clarke Occurrence, Beardmore Area, Ontario
======================================================================
Vancouver, B.C., March 20, 2007. Alto Ventures Ltd. (ATV: TSX-V) is
pleased to provide results for holes MUD07-08 to 12 from the Beardmore
area diamond drilling program which was completed at the end of
February. 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. These new holes
tested the Clarke gold occurrence, one of several surface gold showings
on the Mud Lake project that have not been drilled previously.
These results combined with results obtained from drilling at the
Oliver Severn and Trench 6 (please see news release dated March 5,
2007) continue to provide encouragement for the Mud Lake project
(please see table below).

Because the shear at the Clarke occurrence is folded and there was some
uncertainty as to plunge directions, the five holes were spaced 25 m
apart and tested for gold along 100 m section of the shear. The
drilling has confirmed the folding and plunge directions to the
southwest and holes MUD07-11 and 12 intersected shearing, veining and
gold. In hole MUD07-11 the shear divides into two branches and both
carry significant gold including 2.11 g/t across 2.0 m and 2.35 g/t
across 1.7 m. MUD07-12 is the most southerly hole and it intersected an
impressive zone of shearing containing an 8.0 m section which assays
almost one gram per tonne gold and includes a quartz vein breccia that
assays 2.16 g/t gold across 2.0 m. Holes MUD07-08, 09 and 10 were
drilled up-plunge and did not intersect significant shearing or
mineralization.
This minimal-size 753 m drill program tested three surface gold
showings occurring along the six km Mud Lake Shear. The results have
surpassed objectives because well developed shear zones containing
quartz veins that carry significant gold, including high grades, were
intersected. The intersection of gold at each of the three areas
confirms that gold is abundant in the region and highlights the need
for more work on this under-explored property. Plans for the 2007
summer field season are being formulated.
Assay results for the Cote-Archie Lake and the Greenoaks holes are
pending and will be available for dissemination within the next few
weeks.

QualityAssurance/ 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.
