Excellent progress was made towards this objective with secondary copper intersections noted in almost all of the holes that were drilled within the central mineralized zone (see map at Website).

Drilling in the Corriente Copper Belt over the last twenty months by Corriente has totalled approximately 28,000 metres in 125 diamond drill holes. Exploration in the region to date has identified four prospects with significant total copper resources and in addition, numerous drill targets remain to be tested in the Belt. Development of the project over the next period will include evaluation of copper resources from the Warintza area together with two nearby project areas in the north part of the Corriente Copper Belt (Panantza and San Carlos San Carlos (săn kär`lōs), residential city (1990 pop. 26,167), San Mateo co., W Calif.; inc. 1925.
