Copper mineralization in the Rudna concessions occurs over an area of 40.0 km2. The distribution of the various lithological types of ore is controlled by the relief of the top of the White Footwall Sandstone, principally by the disposition of elevations (hills) and flats (depressions or valleys). From south to north, the main elevations are:
- Southern Rudna Elevation on the 900 m level : isometric dome with a size of 1 km by 1 km in plan view.
- Central Rudna Elevation between the 950 m and 1,000 m levels : 300 m to 1,000 m wide ridge elongated west-northwest with flanks sloping 10 degrees southeast and northwest.
- Northern Rudna Elevation on the 1,050 m level : west-northwest elongated ridge with dimensions similar to the Central Rudna Elevation.
- Tarnówek Elevation on the 1,100 m level, with a width of about 800 m.
- Zelazny Most Elevation, interpreted from drill intersections in the northern margin of the Rudna mining area.
It appears that these elevations are simply ridges between broad and flat valleys of preZechstein origin. This hypothesis is supported by wedging out of the Cupriferous Shale over the elevations.
There are fundamental lithological differences between the elevations and the flats. A typical profile for the flats contains all lithological units, such as the White Footwall Sandstone, Boundary Dolomite, Cupriferous Shale and Basal Dolomite. Profiles through the elevations, on the other hand, begin with the ........
