TORONTO, Ontario (May 3^rd, 2007) -- GlobeStar Mining Corporation ("GlobeStar" or the "Company") (TSX: GMI) is pleased to announce results from its latest drilling program at the Cerro de Maimn development project in the Dominican Republic.  In January 2007, the Company completed a 24 drill hole program (totaling 2580 meters) in and around the measured and indicated resources at their Cerro de Maimn open pit mine project.  The goal of the program was to improve confidence in existing areas of the resource, test for extension of the massive sulphide at depth, and provide samples for metallurgical testing.  Results for four holes were disclosed on February 19, 2007 (http://www.globestarmining.com/press/pdf/gmi114_2007feb19.pdf) and this release presents summary results of the remaining 20 holes (see table below), which completes the program. 

⁽¹⁾ Intercepts were calculated allowing 5 meters of internal dilution and using a 1% Cu cut off grade.

⁽²⁾ Hole CM-184 targeted the upper oxide cap, average grades are based on down the hole compositing using a 1 grams /tonne Au cut-off grade and 5 meters of internal dilution.

⁽³⁾ Hole CM-186 was temporary abandoned at 52.2 meters in massive sulphide mineralization. The hole was continued and is waiting for assays.

"These results confirm the high grade nature of the Cerro de Maimn deposit," commented Bill Fisher, CEO of GlobeStar. The Company is committed to its Copper exploration program, both at the mine and with the follow-up of the recently completed EM/Mag airborne survey. This complements our Nickel exploration program, which has already completed 27 holes of the 67-hole infill program in the Cumpi Hill and Loma Mala areas.

Seventeen out of the twenty drill holes returned intercepts of massive and semi-massive sulphide mineralization (see the table above) including holes CM-170 and CM-180 that intersected 7.8 and 9.4 meters of massive sulphide lenses (true thickness) with average grades of 8.4 % Cu and 11.1 % Cu, respectively. These results confirm the high Cu grade continuity of the Cerro de Maimn mineralization and the thickness of the main ore body. The Cerro de Maimn open pit reserve model will integrate the new assay data with past drilling to update the ore resources this summer.

This in-fill drilling program also seeks additional information to characterize the overburden, the weathered zone, completion of a 3D geological model, and establishing the final criteria for the detailed life-of-mine mining plans.  In addition, SGS Lakefield will use these samples to perform further metallurgical tests in order to optimize recoveries and improve concentrate grade in the later years of mine life.  The metallurgical test program will also seek to determine if process enhancements can optimize saleable product in either copper or zinc concentrates.

William Fisher P.Geo, CEO of GlobeStar Mining Corp. who is the Company's Qualified Person for purposes of National Instrument 43-101 prepared this press release. All core samples were split and prepared for shipment at the Cerro de Maimn mine site under supervision of the Company's geologists.  The samples were shipped to SGS Lakefield in Canada where sample preparation and assays were completed. SGS Lakefield carried out chemical analyses. Gold was analyzed by fire assay, copper by XRF for samples > 0.1% Cu and by AA for samples below 0.1% Cu, whereas silver and zinc were analyzed through ICP.

About GlobeStar

GlobeStar Mining Corp. is a well funded mine development company, developing the permitted Cerro de Maimn copper/gold project, currently anticipated to be due for completion in summer 2008.
