Global Copper Intersects 255 Meters Grading 1.01% Copper Equivalent(ii) in Step-Out Drilling in the Las Guias Zone at Relincho, Chile; Drill Program Expanded

VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 9, 2007) - Global Copper Corp. ("Global") (TSX:GLQ) is pleased to announce the results of twelve additional holes from the sulphide drilling program at its Relincho copper-molybdenum project located 60 kilometers northeast of Vallenar, in Region III, Chile. The results are highlighted by step out hole RG06-189 in the Las Guias zone that intersected 255 meters from 364 meters grading 0.67% copper and 0.057% molybdenum (1.01% copper equivalent(ii)) including 26 meters from 574 meters grading 1.46% copper and 0.125% molybdenum (2.22% copper equivalent(ii)). Hole RG06-183, also a step out at Las Guias, intersected 418 meters grading 0.43% copper and 0.027% molybdenum (0.59% copper equivalent(ii)) from surface.

The results from the latest 12 drill holes are shown in the table below:

(i) Diamond drill holes have been drilled from the bottom of previously
drilled RC holes (pre-collars). For that reason the number of the pre-
collar is not the actual order in which these holes were drilled as part
of the sulphide program. The first column indicates the sequence in which
the sulphide holes were drilled.

(ii) Copper equivalent is calculated for primary intervals using US$1.00/lb
Cu and US$6.00/lb Mo and is not adjusted for metallurgical recoveries as
these remain uncertain. The formula used is as follows:
CuEQ = Cu% + (Mo% x 6)


The deeper intersections of higher grade copper and molybdenum mineralization at Las Guias are related to the Relincho porphyry which has been intercepted by recent holes and was previously unknown in this area. The Relincho porphyry is the main driver of mineralization at Relincho and intersecting it at Las Guias suggests that the area of copper-molybdenum mineralization in this area may be significantly larger than previously thought.

The current objective of the sulfide drill program is to continue to step out eastwards, extending the Las Guias zone towards the previously drilled Marja zone to its west. Should the two connect, a large zone of continuous copper and molybdenum mineralization will be defined between Relincho and Marja, a distance measuring approximately 2.5 kilometers.

To date, 50 holes totaling 24,259 meters have been completed in the sulphide drill program. In June a third rig was mobilized to the project and the program is now forecast to continue until at least September 2007. On completion of the drill program the current NI 43-101 sulphide mineral resource estimate will be updated to include the results of the sulphide drill program.

The existing sulphide resource estimate, calculated in December 2003 prior to the current drilling program, delineated Measured and Indicated Resources of 174 million tonnes grading 0.59% copper and 0.024% molybdenum (0.73% copper equivalent (ii); 2.3 billion pounds copper; 97.4 million pounds molybdenum) and Inferred Resources of 100 million tonnes grading 0.51% copper and 0.017% molybdenum (0.61% copper equivalent(ii); 1.1 billion pounds copper; 37.9 million pounds molybdenum) at a 0.4% copper cutoff.

In addition, a NI 43-101 compliant copper oxide resource estimate was completed earlier this year after the completion of the oxide drill program. That resource estimate delineated Indicated Resources of 107 million tonnes grading 0.33% copper (778 million pounds copper) and Inferred Resources of 13 million tonnes grading 0.27% copper (77 million pounds copper) at a 0.2% copper cutoff.

The technical reports for the oxide and sulphide resource estimates can be viewed on both the Global website at www.globalcoppercorp.com and SEDAR at www.sedar.com.

Leo Hathaway, P.Geo., is the Qualified Person as defined by National Instrument 43-101 for the Relincho Project. The quality assurance/quality control program is monitored by independent consultant Dr. Bruce M. Davis, Chief Geostatistician for Norwest Corporation and managed on site by Patricio Valenzuela, a Chilean geologist with over 24 years of experience. Logging and sampling are completed at Global's secure facility located at the project. The drill cores are mechanically split on site and samples securely transported to the ACME's facilities in Santiago, Chile for sample preparation and analysis. Total copper content is determined by three-acid digestion with atomic absorption finish. Global inserts standards, blanks and duplicates selected on a random basis into the sample stream and sends 5% of the sample pulps to check laboratories in Santiago, Chile.
