HIGH GRADE MASSIVE SULPHIDES INTERSECTED

AT DUCK POND

 

Thundermin Resources Inc. (“Thundermin”) and 50% joint venture partner Queenston Mining Inc. (“Queenston”) announce that high grade, copper-zinc-lead-silver-gold, massive sulphide mineralization has been intersected in the first two holes drilled on the 11,796 hectare Duck pond property which is located 30 km southeast of Buchans in west-central Newfoundland (See Table and News Releases dated march 2, May 6, and June 8, 1999)

The Duck Pond property hosts two, volcanogenic copper-zinc-lead-silver-gold 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 Ag and 0.9 g/t Au.  The first phase program, consisting of a minimum of 6,000 metres of drilling in 20 holes, will focus primarily on confirming and expanding the known resources in the Upper Duck Pond and Sleeper lenses of the Duck Pond deposit.  Two drills are currently in operation and the program is expected to take approximately four months to complete.  Further drilling results will be released periodically during the course of the program.

 

Holes DP-99-201 and 202 are infill holes designed to confirm the continuity and grade in the Upper duck lens where previous drilling on 50 metre centers has outlined an inferred resource of 3,880,000 tonnes grading 3.3% Cu, 6.7% Zn, 1.1% Pb, 71.0 g/t Ag and 1.1 g/t Au.  The current holes were collared in a staggered pattern approximately 25 metres from previous holes.  These holes confirm the continuity and high grade nature of the massive sulphide mineralization in the Upper Duck lens.

 

Hole DP-99-201 also intersected high grade copper-zinc mineralization over 1.55 metres in the poorly defined Sleeper lens which lies approximately 60 metres below the Upper Deck lens.  This intersection occurs 35 metres from the nearest ore grade interval in the Sleeper lens and enhances the potential for additional tonnage.  Previous drilling in the Sleeper lens has outlined an inferred resource of 676,000 tonnes grading 1.7% Cu, 8.7% Zn, 1.2% Pb, 62.5 g/t Ag and 0.5 g/t Au.
