These new results significantly expand the gold-copper exploration potential of the project and show excellent opportunity for discovery of a deposit similar in style to the nearby Marte-Lobo (6 million ounces gold resources) or Refugio (5 million ounces gold reserves and resources) deposits. Mogote is located along the Argentina-Chile border between the prolific Maricunga and El Indio mineralized belts. Geologic and alteration mapping suggest the presence of a very large, high-level, gold-copper porphyry system on the Mogote property. Detailed mapping, rock chip sampling, and talus-fines sampling have defined two large, intersecting target areas at Mogote which are defined by coincident >100 ppb gold and >500 ppm copper in talus-fines sampling and have been confirmed by rock chip sampling. Filo Central measures 4,000 metres by 800 metres and trends north-northwest; it includes two higher-grade (>200 ppb gold) cores measuring 1,400 by 400 metres and 900 by 250 metres. Filo Este is 2,000 metres by 700 metres in size and trends east-west; within this zone a core of >200 ppb gold in talus fines measures 1,200 by 250 metres. Alteration in the area of these zones is clearly indicative of the uppermost portions of a porphyry system and includes a central core of widespread potassic alteration (biotite, potassium feldspar, and quartz-magnetite veining), quartz veining and stockwork in porphyry and surrounding sediments, a halo of disseminated pyrite, and an outer zone of propylitic alteration (chlorite, pyrite, epidote). All of these alteration styles are overprinted by argillic alteration. The >100 ppb gold contour in talus fine sampling has been previously used, with documented success, to define several large gold-copper deposits in the Maricunga belt. The anomaly at Filo Central is much longer and more continuous than that defined during the early stages of the Refugio discovery; the Filo Este anomaly approximates the size of the early talus fines anomaly at Lobo. Neither of these targets have been drill tested or trenched. The exploration work at Mogote was carried out by Linus Keating, D.Sc. under the supervision of Lindsay Bottomer, P.Geo., IMA's Qualified Person for the project. ON BEHALF OF THE BOARD /s/ Gerald G.
