  Cadillac Ventures Inc. (TSX VENTURE: CDC) ("Cadillac" or the "Company") is pleased to report that a recently completed updated resource estimate by P&E Mining Consultants Inc. for the former Thierry mine consists of an Indicated Resource of 6,228,000 tonnes containing 1.92% Cu and 0.2% Ni and an Inferred resource of 8,379,000 tonnes containing 1.79% Cu and 0.16% Ni using an NSR cut-off of C$46/tonne.

1.  Mineral resources which are not mineral reserves do not have
demonstrated economic viability. The estimate of mineral resources may
be materially affected by environmental, permitting, legal, title,
taxation, socio-political, marketing, or other relevant issues.
2.  The quantity and grade of reported inferred resources in this estimation
are uncertain in nature and there has been insufficient exploration to
define these inferred resources as an indicated or measured mineral
resource and it is uncertain if further exploration will result in
upgrading them to an indicated or measured mineral resource category.
3.  The mineral resources in this press release were estimated using the
Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM
Standards on Mineral Resources and Reserves, Definitions and Guidelines
prepared by the CIM Standing Committee on Reserve Definitions and
adopted by CIM Council December 11, 2005.
4.  The 2 year trailing average US metal prices used in this estimate were
$2.75/lb Cu, $7.62/lb Ni, $14.75/oz Ag, $945/oz Au, $1,350/oz Pt and
$308/oz Pd. The C$US$ Exchange rate was 0.95.
5.  Overall payable metal in the NSR calculation were 84% Cu, 13% Ni and 37%
for Ag, Au, Pt & Pd.
6.  Costs used to determine the C$46/tonne NSR cut-off value are as follows:
mining C$28/tonne, processing C$13/tonne and G&A C$5/tonne.

The resource statement was prepared at the request of Cadillac using the additional data generated by drilling 20 holes in 2007 and 2008 by the former operators of the property as well as the drilling used in previous NI 43-101 resource estimates. In all, 1,180 surface and underground drill holes were utilized on 15 metre drill sections in the resource estimate. Block model grades were determined with inverse distance squared (1/d2) interpolation. The Thierry mineralization has a strike length of 1,300 m and a down dip distance of 1,600m.

Cadillac is the sole owner of the former Thierry Mine which sits on approximately 4600 hectares of leased land outside the Town of Pickle Lake in Northern Ontario. This resource statement was prepared by P&E Mining Consultants Inc. under the supervision of Eugene Puritch P.Eng in a manner which meets the guidelines of National Instrument 43-101. A technical report will be filed within 45 days of this press release.

Cadillac is pleased by the significant increase in the resource evident when the June 2010 resource statement in Table 1 is compared against the September 2006 statement in Table 2 below. Drill results incorporated into the updated June 2010 statement include intersections at a vertical depth of greater than 900 metres, and several holes which encountered mineralization in previously untested areas of the deposit.
