VANCOUVER, B.C.--(BUSINESS WIRE)--March 2, 2000

Canabrava Diamond Corporation (CDNX:CNB.) and Navigator Exploration Corporation (CDNX:NVR.) are pleased to announce that over 16,000 hectares of claims have now been staked in the immediate vicinity of Monopros' Victor Pipe in the James Bay Lowlands, Ontario. This staking constitutes the first phase of a significant ground acquisition program by the partners as part of a major diamond exploration initiative on the Superior Craton.

The Superior Craton has recently become a focus for new diamond exploration in Canada, following the news that Monopros (the Canadian arm of De Beers) commenced a 10,000 tonne bulk sampling program on the diamondiferous Victor pipe in early January 2000. The 18-hectare Victor kimberlite is the largest of 16 pipes that comprise the Attawapiskat cluster. Published reports confirm that 14 of these pipes are diamondiferous.

Canabrava and Navigator have acquired over 1,000 claims in the area immediately adjacent to the Attawapiskat kimberlites, covering more than 30 circular airborne magnetic anomalies identified from a regional magnetic dataset. In addition, five high interest magnetic anomalies have been identified and staked in an adjacent area. The next stage of exploration on the Severn Project will include detailed airborne geophysical surveying of the claimed areas.

Preliminary results for the 204 samples collected in Canabrava's 1999 reconnaissance sampling program have recently been received, and results are positive beyond expectation. The program was designed to test an extensive area of prospective terrain on the Superior Craton by careful consideration of the sampling medium in relation to the regional glacial geology. Abundant kimberlite indicator minerals including pyrope garnet, chromite, picro-ilmenite, chrome diopside and olivine, have been recovered. Analysis of results is ongoing.

Under the terms of the agreement, Navigator can earn a 50% interest in the Severn Project by spending $1.75 million over two years, with a firm commitment to spend $1 million within the first year. Navigator is the operator of the project. Once Navigator has earned its 50% interest, exploration expenditures will be jointly funded on a pro-rata basis.

Canabrava Diamond Corporation is actively exploring for diamonds in Brazil and Canada both independently and through major joint ventures with Kennecott Canada Exploration Inc., SouthernEra Resources Limited, Paramount Ventures and Finance Inc. and Navigator Exploration Corp. Canabrava is 54.2% owned by Southwestern Gold Corporation (SWG-T).

Navigator Exploration Corp. is currently exploring for gold and diamonds in Northern Canada and gold and base metals in Ireland.
