Also Northern Abitibi Mining Corp (NAI)
Donner Minerals and Northern Abitibi have received assay results for the 15.7m
wide zone of massive sulphide mineralization encountered in diamond drill hole
97-96. Hole 97-96, on Donner-Northern Abitibi joint venture ground, is
approximately 200m southwest of hole 97-75 and approximately 470m west of
hole 97-67, The following analyses were completed by XRAL Laboratories, a
division of SGS Canada, of Don Mills, Ontario.

The average grade over the 15.7m interval is 1.13% nickel, 0.78% copper and
0.20% cobalt. These results, combined with the results of nearby holes 97-67 and
97-75, have significantly increased the potential for a massive sulphide deposit in
the South Voisey's Bay project area. All drilling and sample handling for the 1997
exploration program were carried out under direct supervision by Teck
Exploration personnel.
Summary of All 1997 Joint Venture Exploration Programs
The South Voisey's Bay project has now been the focus of three years of
fieldwork by the company and its joint venture partners.
Exploration during 1997 was focused on the main areas of exposed gabbroic
rocks referred to as the north and south Gabbro. Reconnaissance mapping was
completed over the entire project area and detailed grid mapping was conducted
over the north and south Gabbro. Ground magnetic and electromagnetic surveys
(242 line kilometers) were conducted over geophysical anomalies detected by
previous airborne surveys. Detailed gravity surveys (425 line kilometres) were
completed over all areas of known gabbro and a total of forty-four holes totalling
12,419m have been drilled on selected targets.
Although the gravity surveys were initially designed to directly identify areas of
sulphide mineralization, results of the first few drill holes showed that the large
anomalies defined by these surveys represent thickened parts of the gabbro
intrusions or potential feeder zones, favorable sites for accumulation of massive
sulphides. Data from the gravity surveys has defined several areas of interest.
To test the anomalies, several widely spaced drill holes were completed in each of
the areas of interest. Although economic grade mineralization was only
encountered in the west central part of the project area (Donner-Northern Abitibi
joint venture) magmatic mineralization was observed in almost all of the areas
tested. Given that these zones may be favorable sites for the accumulation of
massive sulphides, extensive additional drilling will be required to fully evaluate
their potential. |
