Rockinghorse Property, Nunavut

------------------------------

(Tahera / Kennecott Joint Venture)

Tahera Corporation and Kennecott Canada Exploration Inc. (a member of the Rio Tinto group of companies) have mobilized the Rockinghorse Property exploration program. A minimum budget of C$1.5 million has been approved for the exploration program, although the budget may be increased substantially if further positive results are returned.

Ground geophysical surveys (gravity and EM) are underway in the area where the highly diamondiferous Anuri kimberlites are located. A drilling program will follow to further delineate the Anuri kimberlites, and to explore for additional kimberlites in the immediate vicinity. The Anuri kimberlites are situated near the head of an extensive kimberlite indicator mineral train. The broad extent of the kimberlite indicator mineral train coupled with its mineral chemistry indicate that additional diamondiferous kimberlites may exist in the immediate area. Approximately 25 kimberlite targets will be drilled in the Anuri orbit (area within 20-kilometre radius of the Anuri kimberlites) as part of the 2002 exploration program.

The Rockinghorse Property is located in Nunavut's emerging Coronation diamond district, approximately 450 kilometres northeast of Yellowknife, Northwest Territories. The highly diamondiferous Anuri kimberlites were discovered in the summer of 2001 near the centre of the Rockinghorse Property. An aggressive land acquisition program was completed following the discovery of the kimberlites. The Rockinghorse Property now encompasses approximately 150,000 hectares (370,000 acres).

Kennecott is the operator of the joint venture, and holds an option to earn a 62.5% interest in the property by funding all costs up to a mine development decision.

Kevin Kivi, Principal Geologist, North American Diamonds for Kennecott Canada Exploration Inc. is the qualified person for the project.

Jericho Claims

--------------

As previously announced, the Jericho Claims exploration program was mobilized in early March 2002. Priority kimberlite target areas have been outlined in close proximity to the Jericho pipe where diamondiferous kimberlite float was discovered in 2001, and in the Bird Lake and Contwoyto areas, where several unresolved kimberlite indicator mineral trains have been identified in previous exploration campaigns. Ground-based geophysical surveys (EM, mag and gravity) are underway over the target areas. At least 20 kimberlite targets will be tested following completion of the geophysical program. A minimum budget of C$1 million has been established for the program, although the budget may be increased substantially if further positive results are returned.

Kennecott is the operator of the program. Pursuant to a Letter of Understanding, Kennecott has the option to incorporate Tahera's Jericho Claims into the existing joint venture between the two companies by September 2002.
