The rock contains pseudomorphs after olivine-I, laths of mica and large (2-3 mm) picroilmenite grains which, according to the microprobe analysis, are chemically identical to earlier identified kimberlitic picroilmenite. Coarsely bladed quartz pseudomorphs after calcite in veins and in the breccia matrix is suggestive of a boiling zone, typically associated with low sulfide epithermal gold mineralization. The most attractive of these prospects is the Dolnoseltsi prospect where a two-metre wide vein exposed in a recent trench exhibits strong epithermal textures including bladed carbonate pseudomorphs, crustiform-colloform banded veins and massive chalcedony. |
