The Hendrik is a former Dutch coal mine. On its dumps one may find Gypsum, Chalcopyrite, Pyrite, Calcite, Dolomite, Aragonite and Sphalerite. A few others like Millerite are more rare. I visited the dumps several times and managed to make quite a few finds. A find I did in 2019 with Fluorite is extremely rare and not documented before. The location is becoming smaller over time as the dump is re-used. But the digging provides new opportunities.
