Cadillac Mining Corporation: West Cadillac Project; Arntfield Drilling Results

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 20, 2007) - Cadillac Mining Corporation (TSX VENTURE:CQX) announces the results from its three-hole, 1997-meter winter drilling program on the Arntfield #2 Mine area situated within the Norcoeur Option claims, west of Rouyn-Noranda, Quebec.

Core holes CM07-21 and 22 were drilled south at -60 degrees to intersect the Arntfield-Francoeur shear up- and down-plunge from a strongly mineralized zone cut in early 2005 by drill hole DDH RO05-04 that returned 3.3 meters averaging 18.45 g Au/tonne. This structure consists of a broad NE-plunging zone that remains open down-plunge. CM07-23 was collared about 200 meters east of CM07-22, and drilled southward at -60 degrees to test the down-dip extension of the deepest ore zone in the Arntfield #2 Shaft workings.

DDH CM07-21 cut the target structure between 245 and 249 meters (down-hole), and returned 4.3 g Au/t over 4.0 meters within a broad zone of strongly pyritic mineralization which averages 3.00 g Au/t over 10.0 meters (all true widths). The pierce-point is situated about 40 meters up-dip from the earlier intercept in RO05-04.

DDH CM07-22 cut the Arntfield structure at 393 meters depth where it assayed 5.08 g Au/t over 1.0 meter. This intersection is situated approximately 150 meters down-plunge of the RO05-04 intercept.

These two Cadillac Mining intersections are bracketed by significant drill intercepts in several holes completed between 1986 and 1989. The area of known mineralization measures about 200 meters by 100 meters in plan, and is open to the northeast.

DDH CM07-23 intersected the Arntfield shear at 580 meters depth, about 200 meters down-dip from the deepest workings of the Arntfield #2 Mine. However no economic values were returned.

The above results are tabulated below, along with a number of unanticipated gold intercepts in the upper portions of all three holes. These intersections, situated north of most of the historical work, lie along an east-west trend parallel to the Arntfield structure. This raises the possibility of a previously unrecognized mineralized zone. Gold values are low but notable, in that two of the intercepts are exceptionally broad. Further work is needed to assess the significance of these results.

Drill Hole From(m) To(m) Interval(m) Grade Au
CM07-21 22.8 24.2 1.4 4.9 g/t
240.0 250.0 10.0 3.0 g/t
Includes 245.0 249.0 4.0 4.3 g/t
CM07-22 176.0 190.0 14.0 335 ppb
393.0 394.0 1.0 5.08 g/t
CM07-23 253.0 279.0 26.0 417 ppb

Cadillac has completed a digital compilation of its 2005 - 2007 drilling results, and all available historical Arntfield data (including extensive underground workings and a large number of surface drill holes). This information will be used to generate a comprehensive 3D model which will facilitate the analysis of all data produced since the early 1930's.

The Norcoeur option, negotiated with Richmont Mines Inc. in 2004, requires the Company to expend $2.2 million on exploration in stages by November 2008. Since November 2004 approximately $400,000 has been spent on the option in qualifying expenditures.

The West Cadillac project is under the direct supervision of Andre J. Audet, P.Eng., Vice-President, Exploration, a Qualified Person under NI 43-101.

In addition to the ongoing work on gold projects related to the Cadillac Break in western Quebec, management is currently considering several new opportunities that will diversify the Company's exploration focus.
