C1 Vein, Zona Canchete

The shaft on the C1 Vein has been deepened to the 100m level. A cross cut is currently being driven to

intersect the veins to the north of the shaft. In addition, the length of the C1 Vein has been extended by

additional drifting on the 60m and 40m levels. On the 60m level, the vein has been traced for

approximately 170 meters, with consistently good grades (average 0.8 oz/t gold in 67 face samples) in the

easternmost 120 meters of the vein. On the 40m level, the vein has been traced for 110 meters with

consistenly good grades throughout (average 1.2 oz/t gold in 57 face samples). Near the east end of the

drift on the 40m level, one face sample returned a robust assay of 11.0 oz/t gold across 12.0cm

The C1 Vein has yielded consistently high assay results for a strike length of over 100 meters and for a

vertical depth of 100 meters. To date, face-sample assays and bulk-sample assays have averaged

approximately 1.0 oz/t gold and a total of 332 tonnes of bulk sample material averaging 0.97 oz/t gold has

been extracted from ongoing underground exploration development .

The C1 Vein is only one gold-bearing quartz vein located at Zona Canchete within the northern area of

the Property. There are eight main veins with an aggregate length of about 920 meters within an area

measuring 350m X 480m in Zona Canchete.
