Global Copper Reports 9 Additional Drill Holes and Acquires Surface Right and Additional Mineral Rights at Relincho

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 30, 2008) - Global Copper Corp. (Global) (TSX:GLQ) is pleased to announce results from a further nine holes in the sulphide drilling program at its Relincho copper-molybdenum project in Chile. Results are highlighted by step-out hole RG06-217 that returned 220 meters grading 0.77% copper and 0.050% molybdenum (1.07% copper equivalent(ii)) including 76 meters grading 1.20% copper and 0.091% molybdenum (175% copper equivalent(ii)).

The latest batch of drill holes represent a mix of step-out and infill drill holes designed to expand the margins of the Las Guias zone as well as test for continuity within the defined zone of copper-molybdenum mineralization.

Copper-molybdenum mineralization occurs over wide intervals in every hole with higher grades characteristically associated with the contact zone of the porphyry intrusive at Las Guias. There is insufficient geological information to calculate true widths of drill intercepts.

The assay results from the nine new holes are shown in the table below. A map is provided to show the location of the drill holes.

(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 sulphide 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.All intervals are in sulfide mineralization
unless otherwise noted.


To date, 95 holes totaling 60,200 meters have been completed in the sulphide drill program. Four diamond drill rigs are now operating on the property with a fifth rig being mobilized to the project in May. The drill program is focused on expanding the current mineral resource, in particular, the higher grade contact zone at Las Guias. The program is forecast to continue for the remainder of 2008 and will include both exploration and infill drilling.

The 43-101 technical report, detailing the current oxide and sulphide mineral resource estimates, can be viewed on both the Global website at www.globalcoppercorp.com and SEDAR at www.sedar.com.

On April 14, 2008 Global announced that it has entered into an agreement with Teck Cominco Limited ("Teck") for Teck to acquire Global by way of an arrangement under the Business Corporations Act (British Columbia). Under the arrangement, Global shareholders will receive C$12.00 or 0.26667 of a Teck Class B subordinate voting share per Global common share, subject to pro-ration, and subject to adjustment in certain circumstances, and one share of a new company, to be named Lumina Copper Corp. Further details on Global s agreement with Teck can be found in the Global news release, dated April 14, 2008, posted on both the Global and SEDAR websites.

The Company has also entered into an agreement to acquire approximately 52,000 hectares of surface rights over the Relincho project and potential infrastructure and tailings site areas. As part of the transaction, the Company has a four year option to acquire an additional 198,000 hectares of surface rights. In addition, the Company has acquired a series of mineral rights that lie immediately to the south of the Relincho project area.

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.
