Trojarova Antimony-Gold Mine
Several historical resources have been calculated using the Soviet-style classification of mineral deposits:
The first was in 1989 based on initial drilling program, where they defined blocks of 1.665 million tonnes @ 2.77 % Sb & 0.81 g/t Au*
The second resource was calculated in 1992 based on previous results and infill drilling: 0.831 million tonnes @ 5.645 % Sb & 0.676 g/t Au*
The most recent historic resource estimation from 1995 reflected the data obtained from the underground exploration by the Trojarova adit. Exploration was prematurely terminated before drill-verified rich ore was accessed and therefore the reserve estimate is more pessimistic: 0.415 million tons @ 0.162 % Sb and 1.148 g/t Au. The exploration project was also primarily aimed on Au-As ore rather than Sb-rich ore.

At the top right can be seen the adit entrance which stretches nearly to the Antimony lens/resource at the bottom left.
