The Pezinok mine, an antimony deposit mined since 1940, has yielded hundreds of specimens of some of the world's finest kermesite, excellent valentinite and stibnite, and rare species such as chapmanite and garavellite.
The rare mineral chapmanite was first described from the Pezinok mine by Polak (1983, 1988) as pale, yellow-brown, powdery aggregates on metamorphosed black shale from the Sirkova stope and the Stanislav horizon.
