La Falda – Gold-bearing banded quartz veins Lithocap Au-Porphyry (Central) Au-Porphyry (Norte) Gold-bearing banded quartz veins at La Falda. Veins similar to these host the main orebodies in the other Maricunga gold-porphyry deposits The exploration targets at La Falda are: A multi-million ounce near-surface gold-porphyry and associated high-grade epithermal gold-silver mineralisation The potential scale of the porphyry target can be extrapolated from Kinross’ Maricunga Mine, Lobo-Marte and Cerro Casale deposits; Andina Minerals’ Volcan Project and Exeter Resource Corporation’s Caspiche deposit 7

La Falda – A Panoramic View, looking south Au-Porphyry Lithocap (Central) Au-Porphyry (Norte) Jeffrey W. Hedenquist, is an independent geological consultant specialising in epithermal and porphyry Cu-Au deposits world-wide. In his February 2008 report, following a field visit to La Falda, he summarised: “ These observations indicate that the very top of the porphyry intrusions is exposed, with both Central and Norte host to banded quartz veins typical of the style of veins that are related to mineralisation in other Maricunga porphyry gold deposits; vertical intervals in these ore deposits are up to at least 300 m. As a result of this strong similarity between La Falda and porphyry gold deposits in the Maricunga district, this prospect has taken on a completely new – and positive - perspective” 9
La Falda Porphyry Norte Pole Reduced Magnetic Map A ground magnetic survey has Falda Norte Structure outlined a large (approximately 2 km by 1 km) weak magnetic high around the underlying intrusive Porphyry Central Magnetic highs (pink) are due to Underlying the presence of magnetite and Intrusive are often flanked and cut by strong magnetic lows (dark blue) Circular Feature Magnetite often accompanies gold in Maricunga gold-porphyries Magnetic lows may represent areas where later alteration has destroyed magnetite Similar patterns are observed in Falda Sur Structure other Maricunga porphyries 10
La Falda – IP – Plan of Chargeability at 4200m Elevn. An Induced Polarisation (IP) survey has revealed a 2.4 by 2 km chargeability anomaly This contains a promising target zone (approximately 2 km E-W by 600 m N-S) encompassing all of the magnetic anomaly The anomaly is probably due to sulphides It suggests a large geological feature (an intrusive gold-porphyry?) not solely epithermal gold in linear fracture zones 200 x 200 m grid 11
La Falda – IP Survey – Stacked Chargeability Sections The IP anomaly is consistent with the presence of sulphides below a depth of approximately 100m - persisting to at least 350-400m These stacked chargeability sections indicate extensive sulphides beneath both the lithocap and the porphyry intrusives Drilling will start at the Porphyry Norte sector and step out along the strike of the anomalies 12
La Falda – IP – Plan of Resistivity at 4200m Elevn . The La Falda resistivity data display anomalies characteristic of other Maricunga gold-porphyries In Maricunga gold deposits, areas of low resistivity may: • flank several sides of a typical deposit • be associated with: � a variety of geological structures � propylitic or argillic alteration Low resistivity may also be found at depth below the central gold-hosting zone Areas of higher resistivity are often associated with banded quartz veining and associated silicification 13
La Falda – IP Survey – Stacked Resistivity Sections At La Falda: A zone of low resistivity underlies the central resistive zone at depths of ~300 m Based on the resistivity data, the priority zone for gold exploration is the central resistive zone between sections 515600E and 517000E. At depth, the entire central resistive zone appears to be underlain by low–resistivity material, consistent with observations at other Maricunga deposits. 14
