Consolidated Spire Ventures Ltd. reports Gold Mineralization Expands at the Prospect Valley Gold Project

VANCOUVER, BRITISH COLUMBIA - June 03, 2010 - Consolidated Spire Ventures Ltd. ("Spire"; TSX-V: CZS) and Altair Ventures Incorporated ("Altair"; TSX-V: AVX) are pleased to report that results from the 2010 Phase I drilling program (carried out by Altair, within the South Discovery Zone (“SDZ”) of the Prospect Valley property in southern BC) have continued to extend the strike length and width of gold mineralization.

Assays have now been received from the last 3 holes of the 11-hole program. Hole PV-10-09 was drilled up-dip from, and on section with, holes PV-10-07 and -08 and further extended the width of the gold mineralization to the southeast with an intersection of 27.95m grading 0.41g/t gold. Hole PV-10-08 (previously reported on May 19, 2010) intersected 68.69m grading 0.89g/t gold, including 32.64m of 1.32g/t gold that, in turn, included a higher grade section assaying 2.93g/t gold over 7.53m. The 68.69m interval also included a deeper section of 7.96m grading 1.44g/t gold.

Holes PV-10-10 and -11 were drilled 450m and 550m, respectively, along strike to the northeast and filled-in and extended the strike length of gold mineralization in that direction. The zone is still open along strike to the northeast. The SDZ is now known to have a strike length of more than 600m, although the central 100m - 150m may be offset to the northwest, and further work is needed to test this hypothesis. It is locally more than 90m in vertical thickness, and more than 200m wide in the middle.

“The success of the Phase I drill program is significant, not only because the continuity of gold mineralization should allow us to prepare a preliminary resource estimation, but because the intensity and extent of the mineralization and alteration in the SDZ is indicative of a strong mineralizing system. We have gold anomalies spread over 40 square kilometres at Prospect Valley, some of which are bonanza grade, and we look forward to advancing these targets over the coming summer field season” said Fayyaz Alimohamed, President of Altair.

The Phase I program consisted of 1,127m in 11 drill holes and was successful in proving the continuity of gold mineralization intersected in the SDZ in 2006 and 2007. Highlights from holes PV-10-09 to -11 are listed below and all results from the Phase I program and a map showing drill collar locations can be found on the Consolidated Spire Ventures Ltd. website at www.spireventures.com.

The SDZ occurs in the hanging wall of (above) a moderately dipping fault, with the gold grade typically increasing downward toward the fault. Lower grade rocks near surface are generally oxidized and hematized, while higher gold grades appear to be associated with increased silicification and disseminated pyrite. Rocks on the footwall side of (below) the fault are chloritized and barren of gold mineralization.

2010 Phase I Drilling Highlights

Internal higher grade portions can be up to 20m thick, often close to the aforementioned fault. On some sections, the gold grade appears to be increasing in a down-dip direction (i.e. to the northwest, down the fault) and this theory will be tested in future drilling. This is particularly significant in that the zone is entirely open in this direction.

Drilling to date has only tested the SDZ to an average vertical depth of 60m. The most recently drilled portions of the SDZ have now been defined at approximately 50m centres, which may be sufficient for the estimation of a preliminary resource. The SDZ is part of a geochemical and geophysical anomaly extending nearly 2km in total strike length and up to 400m wide. While it has the potential to host a significant low grade, bulk tonnage epithermal gold system, many other untested targets exist on the property, including bonanza grade gold-quartz veins. A summer field program is currently being designed to follow up on these other areas in order to bring them to the drill stage as quickly as possible.

The Qualified Person for the Prospect Valley Project is Mr. Warner Gruenwald, P.Geo. and VP Exploration for Altair Ventures Inc. The Prospect Valley Gold Project is only 30km south of the world class Highland Valley Copper Mine, and sits within a complex tectonic zone that is interpreted to have provided channel ways for the introduction of widespread gold mineralization.

Altair is the operator of the project and has an option to earn up to a 90% interest in the 107.9 sq km Prospect Valley Property, situated within the Spences Bridge Gold Belt, approximately 3 hours driving time from Vancouver and one hour west of Merritt, BC. The Qualified Person for the Prospect Valley Project is Mr. Warner Gruenwald, P.Geo. and VP Exploration for Altair Ventures Inc.
