Toronto, Ontario The Company has undertaken a program of preliminary test pitting across a favourable horizon of lateritic nickel mineralization at its Buena Vista Project located in Guatemala. A 3090 hectare property called "Sechol" is the first property licensed to the Company's joint venture Guatemalan subsidiary. Chesbar is funding the current US$300,000 exploration program whereby it is earning an additional interest in the project. At completion, Chesbar will vest 70% and its partner, Intrepid Minerals Corp. (CDNX-IAU) ("Intrepid") will own 30%. The Company has applied for four additional licenses in the same area, which after being granted will increase the Company's total land holding to approximately 22,000 hectares. The Company's geologists have identified extensive areas of lateritic nickel mineralization, which will be tested for economic potential in the ongoing exploration campaign.
Lateritic nickel mineralization was identified in the area by Inco subsidiary Exmibal in the early 1970's and steps were undertaken to exploit this nickel at that time but this project was shut down when the large escalation in fuel costs resulting from the OPEC oil crisis made the process then being used uneconomic. In the mid 70's and then again in the mid 90's work by Transmetales and by Cominco Ltd. respectively at the Buena Vista Project completed programs of test pits to assess an area of lateritic nickel mineralization measuring 1900 meters by 800 meters. These pits have been backfilled but some of the resulting data have been made available to the Company's geologists. This property reverted to the Guatemalan government and was acquired from the government by the Chesbar - Intrepid joint venture in 1999 as part of the "Sechol" exploration licence.
The Company's interest in the Buena Vista project is based on the rapidly developing new technology for the treatment of lateritic nickel ores using Pressure Acid Leaching (PAL) followed by Solvent Extraction and Electrowinning (SX/EW). This technology is now recognized as a revolutionary development in the nickel industry and is already being employed in several new operations, notably in Western Australia.
Work by Chesbar to date has included the digging and sampling of tests pits within the previously identified zone, to confirm the results of earlier work and to provide samples for metallurgical test work to determine the applicability of the new PAL-SX/EW process to this material. Numerous test pits are also being dug on other parts of the Sechol property where nickel bearing lateritic material has been identified by Company geologists. Test pitting is an effective method of assessing deposits of this type because, by the very nature and means of formation of laterites, they lie near surface and are relatively easy to dig.
Results of the Company's current tests pits dug at intervals along a 1500-metre length within the previously identified zone of nickel mineralization are presented in Table 1. Pits are hand dug from surface, encountering variable depths until finishing at bedrock. Sampling is conducted in one meter vertical channel samples of the pit walls during excavation. Samples are geologically described, weigh typically 2.5 kg, are tagged and then sent for sample preparation at Guatemala City with final assaying completed at XRAL Laboratories in Toronto, Ontario. It can be concluded that the broad spaced verification pits over the known nickel zone reveal significant nickel values. The average nickel content from the 4 pits just completed is 1.72% Ni.

The Company has begun a metallurgical study of the mineralogy and geochemistry of the nickel mineralization through a series of tests being conducted by Dynatec Corporation's Metallurgical Technologies Division. In conjunction with gaining a necessary understanding of the applicability of new technology at the property, Chesbar is accelerating its "Buena Vista" program of test pitting over the known nickel zones. At the earliest opportunity, the Company hopes to establish a nickel resource base calculated at the Main Zone. The additional test pitting programs conducted over other lateritic targets at the Company's properties are expected to provide significant increments to this resource. Metallurgical test work is expected to be an ongoing activity, as Chesbar will be seeking the most efficient technology for the economic extraction of the nickel contained at the Company's properties in Guatemala |
