| مستخلص: | Geological studies undertaken between 1996 and 1998 demonstrate that both the siliceous ores at the top of the volcanics and the massive sulphides at their base exhibit a strong spatial relationship to Rhyolite B, one of four major chemostratigraphic units identified within the rhyolite succession, and to the margins of the volcanic complex. These spatial relationships, in combination with widely spaced drill intersections, indicate significant resource potential at Parys Mountain, for instance, 15 600 000 to 18 600 000 t of massive sulphide mineralisation at the Engine Zone horizon, at the base of the volcanic succession and 31 500 000 t of disseminated to semi-massive sulphides within the siliceous horizon. The overall deposit grade could be similar to that found in 1990: 1.8% Cu, 3.5% Pb, 6.6% Zn, 130g/t Ag and 1.0g/t Au. Siliceous grades intersected in 1990 averaged 0.4% Cu, 3.2% Pb, 5.8% Zn, 38 g/t Ag and 0.61 g/t Au.
