Overview:

To date, C$3.8 million has been expended on exploration of the Carat property including airborne and ground geophysics, extensive till sampling, mapping and diamond drilling. During the winter of 2001, the CT-55 kimberlite was discovered and two diamonds were recovered from the caustic fusion of 242 kilograms of crater facies. The chemical analysis of chromite grains recovered from the drill core indicates a substantial portion originated within the diamond stability field.

In May 2004, 10 priority airborne anomalies were investigated with detailed ground geophysical surveys. These targets were selected from previous exploration programs conducted over the Carat Property, which included airborne Mag/EM, extensive till sampling and diamond drilling. During the summer of that same year, detailed till and geochemical sampling were carried out over the property in order to follow up 23 geophysical anomalies identified during previous programs. A total of 68 till samples and 74 soil gas samples were collected during this program. In addition, 519 enzyme leach samples were recovered in the area surrounding CT-55, as well as 10 other prospective geophysical anomalies.

The interpretation of sample results from 2004 exploration programs, along with a review of the previously conducted geophysical surveys undertaken on the property since 1998, led the joint venture partners to approve a drill testing program during the third quarter of 2005. The drill program was conducted in July and August. In all, five targets were tested with a total of 740 metres of diamond core drilling. All targets were selected from nominated geophysical anomalies, although one target had a coincident soil gas anomaly. No kimberlite was intercepted.
