General Minerals Corporation-Monitor Porphyry Copper-Silver Target, Arizona Update: Further Encouraging Results.

VANCOUVER, British Columbia -- General Minerals Corporation (TSX: GNM) ("GMC") is pleased to announce continued encouraging results from the Monitor copper-silver property located in Pinal County, Arizona. The property is situated approximately 5 kilometres northeast of Grupo Mexico's (Asarco) Ray porphyry copper complex.

Initial results reported in January (GMC PR 04-02 January 27, 2004) led to the delineation of an area of approximately 2 square kilometres with characteristics suggestive of an underlying porphyry copper occurrence. Subsequent work consisting of additional mapping and sampling has continued to develop and enhance this target.

Continuing work on the property has identified a much larger area which is approximately 2 by 2 kilometres in size that displays characteristics typical of porphyry copper systems with limonite development after sulfide minerals. This area is characterized by fractured Dripping Springs quartzite with hematite, jarosite and goethite developed on the fracture planes. GMC has completed a wide spaced reconnaissance soil grid over approximately two thirds of this area with a total of 170 samples taken. Soil results show elevated metal values, which include anomalous values in copper, lead, zinc and iron over the majority of the area of limonite occurrence. These results are suggestive of a local metal source and further support the potential of an underlying porphyry copper system.

Continued rock chip sampling by GMC has produced results including 0.67% copper and 178 grams per ton silver over 36.6 meters from an open cut in an area located 850 meters south of any results reported in the previous press release. This area is known as the Silverado Zone and is characterized by copper and silver mineralization hosted within fractured Dripping Springs quartzite. Investigation of the outcrop suggests that the area contained primary mineralization of predominantly chalcopyrite which has subsequence  been oxidized. With the identification of the Silverado Zone, GMC has now outlined significant mineralization in the following areas which are located within an area of 1500 x 1000 meters:

These results suggest an oxide copper/silver target is present, hosted within the Precambrian sedimentary sequences and located at shallow depths.

GMC has recently applied for seven additional State of Arizona Exploration leases which have been approved. These leases cover an additional 1,035 hectares and are located to the south and west of the existing property under the control of GMC. The new leases to the west are located within 1400 meters of the Ray Mine complex and add to the overall potential of the Monitor property. The Ray Mine is the second largest producing copper mine in Arizona and last year produced 272.0 million lbs. of copper which was exceeded only by Phelps Dodge's Morenci Mine.

Efforts are continuing to secure a joint venture partner for the further development of the Monitor property. The property has been shown to a number of interested parties.

General Minerals' rock samples were analyzed by ACME Laboratories in British Columbia. ACME is a fully ISO 9002 certified facility. Analyses were carried out by ICP. Mr. Ralph Fitch, President of General Minerals Corporation, is the Qualified Person on the Project as set out by the Toronto Stock Exchange Disclosure Standards and National Instrument 43-101. Mr. Fitch was assisted by Mr. Randy Moore, Professional Geologist number, WA RPG # 1390 also a Qualified Person, and Dr. Jacob Skokan, consulting geophysicist.
