Cadillac Updates Thierry Underground Resource

TORONTO, ONTARIO--(Marketwire - Feb. 23, 2012) - Cadillac Ventures Inc. (TSX VENTURE:CDC) ("Cadillac" or the "Company") is pleased to announce that the underground resource at the Thierry Mine Project has been revised, based upon the operating costs of conceptually combining the operations of the Thierry underground and the K1-1 open pit deposits. The conceptual combination of operations has resulted in a decrease to the NSR cut-off of $5.30/tonne for the underground resource. The impact on the Resource calculation is illustrated below.

February 2012 Updated Resource Estimate at a C$41/tonne NSR cut-off

Class	Tonnes	Cu %	Ni %	Ag g/t	Au g/t	Pt g/t	Pd g/t
Measured	3,233,000	1.65	0.19	4.6	0.03	0.03	0.09
Indicated	5,582,000	1.66	0.19	3.8	0.05	0.05	0.14
Meas&Ind	8,815,000	1.66	0.19	4.0	0.05	0.04	0.13
Inferred	14,922,000	1.64	0.16	6.4	0.10	0.07	0.21

(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
(4)	The January 31, 2012 two year trailing average US metal prices used in this estimate were $3.72/lb Cu, $10.15/lb Ni, $28.18/oz Ag, $1,419/oz Au, $1,663/oz Pt and $639/oz Pd. The C$US$Exchange rate was 0.99.
(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$41/tonne NSR cut-off value are as follows: mining C$30/tonne, processing C$9.50/tonne and G&A C$1.50/tone (Processing and G&A costs were developed on a shared basis with K1-1)

"The impact to the existing resource statement of the lowering of the conceptual combined operating costs for both the Thierry Mine underground and the K1-1 Open Pit deposits, while not resulting in significant additional tonnage at this time, will be positive for project economics and broadens the range of underground material which, may, one day, be economically mined from Thierry underground, should a production decision be made," stated Norman Brewster P.Geo, President and CEO of Cadillac.

Mr. Brian H. Newton, P.Geo, of Billiken Management Services Inc., on behalf of the Company, and Mr. Eugene Puritch, P.Eng. of P&E Mining Consultants Inc. are "Qualified Persons" pursuant to NI 43-101 and have both reviewed and approved the contents of this press release.

About Cadillac

Cadillac is a development-focused copper company currently advancing its 100% owned Thierry Property, near Pickle Lake, Ontario. The Thierry Property consists of the past producing Thierry Mine and hosts two NI 43-101 compliant resources: Thierry Mine and K1-1.

Thierry Mine Deposit

The Thierry Mine is a past producing mine with a current resource estimate consisting of 8.8 million tonnes Measured and Indicated grading 1.66% Cu, 0.19% Ni, 4 g/t Ag, 0.05 g/t Au, 0.04 g/t Pt and 0.13 g/t Pd and 14.9 million tonnes Inferred grading 1.64% Cu, 0.16% Ni, 6.4 g/t Ag, 0.10 g/t Au, 0.07 g/t Pt, 0.21 g/t Pd using a cut-off NSR of C$41/tonne. The deposit remains open at depth and to the west.

K1-1 Deposit

The K1-1 is an open-pit, large tonnage, low grade deposit located approximately 3 km from the past producing Thierry Mine. The Inferred mineral resource estimate for K1-1 within a Whittle pit shell consists of the following: 53,614,000 tonnes grading 0.38% Cu, 0.10% Ni, 1.83 g/t Ag, 0.03 g/t Au, 0.05 g/t Pt, and 0.14 g/t Pd at an NSR cut-off of $41/tonne.
