THUNDERMIN AND QUEENSTON ANNOUNCE BOUNDARY DEPOSIT DRILL RESULTS

 

December 6, 1999..........Thundermin Resources Inc. ("Thundermin") and 50% joint venture partner Queenston Mining Inc. ("Queenston") announce further results from the second phase diamond drilling program on the high grade Duck Pond base metal property.  The 11,796 hectare property, which is located in west-central Newfoundland approximately 30 km southwest of Buchans, is under option from Noranda Inc. and hosts two copper-zinc-lead-silver-gold volcanogenic massive sulphide deposits, the Duck Pond and Boundary, that contain inferred resources of approximately 6,000,000 tonnes grading 3.4% Cu, 6.4% Zn, 1.1% Pb, 61.4 g/t and 0.9 g/t Au.

The second phase drill program consisted of 2,617 m of drilling in 8 holes on the Duck Pond deposit (see News Release of November 22, 1999) and 2,508 m of drilling in 65 holes on the Boundary deposit, which is located approximately 4 km northeast of Duck Pond.  The Boundary deposit consists of two near-surface zones of massive base metal sulphides 250 m apart that, from prior drilling, are estimated to contain an inferred resource of 446,000 tonnes grading 3.5% Cu, 3.5% Zn, 0.5% Pb and 22.8 g/t Ag.  New drill information from the Boundary deposit will be used for preparing a revised resource estimate and for further open pit modeling.  The results for 28 holes recently completed on the North Zone along with the historical Noranda holes are presented in the accompanying Table and Drillhole Location Map.  Assay results for the 37 South Zone holes will be released in one week.

The Boundary North Zone is 275 m long, up to 50 m wide, has a maximum thickness of 25 m and occurs above a maximum depth of 42 m.  The relationship of the North and South Boundary Zones is unknown at the present time.

The Boundary deposit is a fairly classical volcanogenic massive sulphide deposit comprised mainly of pyritic copper-zinc sulphides with associated underlying stringer pyrite-chalcopyrite mineralization enclosed within an extensive chlorite-rich hydrothermal alteration zone.  The massive sulphides are relatively flat-lying and occur within a lapilli tuff footwall unit at the contact with an overlying quartz crystal tuff.  The hydrothermal alteration zone has a similar chemical signature to the alteration zone that underlies the Duck Pond deposit.  A similar alteration style also occurs at the South Moose Pond area where disseminated base metal mineralization has been discovered coincident with an untested electromagnetic and gravity anomaly.  This target will be drilled in the new year.

The Boundary drill program has been partially funded by the Junior Exploration Assistance Program ("JCEAP") of the Government of Newfoundland and Labrador.
