Global Copper Intersects 60 Meters Grading 1.60% Copper Equivalent(ii) In Step-Out Drilling at Relincho

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 17, 2007) - Global Copper Corp. ("Global") (TSX:GLQ) is pleased to announce the results of nine additional holes from the sulphide drilling program at its Relincho copper-molybdenum project located 80 kilometers northeast of Vallenar, in Region III, Chile. The results are highlighted by hole RG06-182 that intersected 344 meters grading 0.47% copper and 0.052% molybdenum (0.78% copper equivalent(ii)) including 60 meters grading 0.70% copper and 0.154% molybdenum (1.60% copper equivalent(ii)).

With this hole and three others, Global has defined a north-south trending zone of higher grade molybdenum in the Las Guias area, extending the known Relincho mineralization to the east. Four of the six intervals comprising this zone are noted in the table below (two in hole RG06-182). The fifth and sixth intervals were previously reported for RG06-78 and graded 1.02% copper and 0.084% molybdenum (1.52% copper equivalent(ii)) over 36 metres from 38 to 74 metres and 0.54% copper and 0.171% molybdenum (1.57% copper equivalent(ii)) over 110m from 110m to 220m. This zone of higher grade molybdenum is found around structures that dip steeply to the east in the area between Relincho and Las Guias. The zone is open to the east, south and at depth to the north. Similar structures have been mapped at surface at Las Guias and will be drill tested in the near future.

To date, 35 holes totaling 13,575 meters have been completed in the sulphide drill program. The program, with two drill rigs, is forecast to continue through June 2007 when the existing NI 43-101 sulphide mineral resource estimate will be updated to include the results of the sulphide drill program. The existing sulphide resource estimate, current to December 2003, 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 has 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.

The latest sulphide drill results from the sulphide drill program are shown in the table below. To view a plan of drill hole locations accompanying this press release please click on the following link: http://www.ccnmatthews.com/docs/GlobalCopper.jpg.

(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 equals Cu% + Mo% x 6.


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.
