Gravity West Mining Corp.: VTEM Aerial Survey Commences on Sibley Properties

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 25, 2007) - Gravity West Mining Corp. (TSX VENTURE:GRW) -

Mr. Livio Susin reports

Gravity West Mining Corp. has commenced a detailed airborne magnetic and electromagnetic survey over its Sibley basin uranium properties. The goal is to generate drill targets for an aggressive drilling program.

The 100-per-cent-owned Sibley basin properties comprise two blocks in the Lake Nipigon area, north of Thunder Bay, Ont., totaling 50,680 acres - the Gull Bay properties and the Voltaire Lake properties.

GeoTech Ltd. of Aurora, Ont., will be flying the survey using its latest VTEM technology - the B-field VTEM system. The survey covering the two properties will consist of 1,379 line kilometres.

The survey will be used to search for basement conductors and resistivity lows that may reflect alteration of the type commonly associated with unconformity-style uranium mineralization.

The Sibley basin is a Proterozoic sedimentary basin that is of the same general age as, and exhibits geological parallels to, the Athabasca basin of Saskatchewan, with its prolific and very-rich uranium deposits.

Gull Bay block

The Gull Bay blocks include a 10-kilometre length of the Black Sturgeon fault, a major structure that runs through the entire basin and divides it into east and west sectors. The fault was active before, during and after deposition of the Sibley basin sediments. The Black Sturgeon fault, as a controlling structure in the basin, is an important target for uranium exploration. All the major uranium deposits of the Athabasca basin show an association with fault structures, which are believed to be the channelways that introduced mineralizing solutions.

Most of the length of the Black Sturgeon fault lies within a provincial park; the Gull Bay property covers one of the few areas where it crosses land that is available for mineral exploration activities. No prior exploration for uranium is recorded in the property area.

The company's acquisition of the Gull Bay blocks was announced in Stockwatch on April 19, 2007, and is subject to its acceptance for filing with the TSX Venture Exchange.

Voltaire Lake blocks

A preliminary prospecting program carried out during the summer of 2006, confirmed the presence of favourable rock types and alteration in exposed basement rocks near the west end of the Voltaire property.

The prospecting program covered an area of exposed basement rocks outside the margin of the Sibley basin, around the west end of the property. Despite extensive overburden cover, this work confirmed the existence of graphitic bands and magnetite-bearing iron formations in the basement rocks. Graphite-bearing rocks are known to be favourable hosts for unconformity-type uranium mineralization in the Athabasca basin of Saskatchewan, and iron formations have been confirmed to be related to uranium mineralization in the Sibley basin. In addition, hematite alteration was found, which is interpreted to have been caused by oxidizing solutions originating in the Sibley sediments.

The area covered by prospecting was deemed to be prospective for the subunconformity variety of uranium mineralization.

On its Black Sturgeon uranium property just to the south of Gravity West, RPT Uranium Ltd. announced in Stockwatch on April 2, 2007, the results of the first phase of a winter diamond drilling program. RPT reported intersections of 4.68 per cent U3O8 over a core length of 0.72 metre in one hole and 0.362 per cent U3O8 over a core length of 0.3 metre in a second drill hole. These drill holes were drilled on the same section as a previously reported hole which intersected a uranium grade of 2.99 per cent U3O8 over a core length of 1.55 metres. Based on these results, RPT announced the commencement of a further 21-hole drilling program totaling approximately 3,000 metres.

Livio Susin, president of Gravity West, states, "Based on our newly completed land package and RPT Uranium's drill results near the Black Sturgeon fault, we feel the timing is now right for our exploration program to commence."
