San Anton announces new resource estimate


    OTTAWA, ON, March 13 /CNW Telbec/ - San Anton Resource Corporation
(SNN:TSX) is pleased to announce that a new mineral resource estimate has been
prepared by Golder Associates Pty. Ltd. ("Golder") based on infill drilling on
the Cerro del Gallo deposit during 2006. Cerro del Gallo is located on the San
Anton property which is 51 per cent owned by San Anton Resource Corporation
and 49 per cent by Goldcorp Inc., and is located in the state of Guanajuato,
Mexico. The new resource is based on 57,592m of drilling in 232 holes compared
to 24,635m of drilling in 110 holes which formed the basis for the previous
estimate. The 2006 infill drilling program was largely designed to better
define the gold rich portion of the Cerro del Gallo deposit and to move a
large portion of the Inferred Resources up into the Measured and Indicated
categories prior to initiating a Pre-Feasibility Study.
    The 2006 drilling program was successful in significantly upgrading the
quality of the resource with Measured and Indicated resources increasing by
44 per cent and now accounting for 74 per cent of total resources. New
estimates were prepared assuming bulk mining and two potential processing
scenarios, conventional flotation-leach using a 0.3 g/t gold equivalent
("AuEq") cutoff grade, and conventional carbon-in-leach using a 0.4 g/t gold
only cut-off grade.
    Gregory Bowes, President & CEO of San Anton stated that "we now have a
high quality, robust resource estimate that will enable us to undertake
preliminary pit designs and scoping studies to evaluate potential development
scenarios. While the total tonnage and contained ounces declined slightly as
drilling indicated limited depth potential to the southeast, the deposit is
still open in a number of directions. We are adding a third rig in order to
step out much more aggressively in 2007 to determine the total size of the
system as well as to accelerate exploration of regional targets."
    The new mineral resource totals 10.19 million ounces of gold equivalent
at a 0.3 g/t AuEq cutoff which consists of 4 million ounces of gold,
171 million ounces of silver and 448,000 tonnes of copper. At a 0.4 g/t Au
only cutoff grade, the resource totals 3.4 million ounces of gold equivalent
of which 95 per cent is in the Measured and Indicated categories.

    Notes to Accompany Mineral Resource Estimate:

    1.  Block model with grade estimate prepared by Golder Associates Pty.
        Ltd., Brisbane Office, Queensland, Australia.
    2.  The mineral resource estimate is based on 232 drill holes to an
        average depth of 248 meters for a total of 57,592 meters of drilling.
        All drill holes have been completed since December, 2004 of which 40
        holes totaling 18,335 meters are HQ diamond core and 192 holes
        totaling 39,257 are reverse circulation face sampled holes.  Most of
        the resource is within 300 meters of the land surface and has been
        drilled on a nominal 50x50 meter spacing.
    3.  Gold assays by 30 gram fire assay with AAS finish (and gravimetric
        check on all samples containing (greater than)1g/t Au), silver and
        copper assays by multi-acid digestion with AAS or ICP finish; all
        assays undertaken by SGS Laboratories, Toronto, Canada.
    4.  In-situ bulk density ranges from 2.64 to 2.67 t/m(3).
    5.  A geological block model with block sizes of 25m X 25m X 12m was
        constructed. A bulk mining scenario has been assumed.
    6.  Au, Ag and Cu grades were estimated by parent block ordinary kriging
        within constrained geological domains.
    7.  High grade cuts were applied for each geological domain ranging from
        1.0 to 4.0g/t Au, 60 to 120g/t Ag and 0.3 to 0.9% Cu.
    8.  QA/QC checks on sampling and assaying quality are satisfactory.
    9.  Au equivalence ("AuEq") has been calculated as AuEq=Au +
        (Ag/60) + (Cu X 2.3). This formula is consistent with all previous
        mineral resource estimates to provide a basis for comparison.  It
        assumes 100 per cent metallurgical and smelter recoveries.
    10. The reported mineral resource estimate has been rounded to
        appropriate significant figures.
