The Helena mining district was the most productive mining area at the end of the 19th century. Above 900 m elevations, rich wulfenite ore was mined between 1878-1951. The transportation adit to Helena district at 784 m leads to the well-known localities for calcite and wulfenite such as Doroteja, Barbara East, Rišperk and Christmas tunnels. Probably the most attractive II. General Level (900 m) with splendid calcites and the Doroteja Level (925 m) with famous bipyramidal wulfenites can be accessed through the inclined shaft from the main Helena adit.

One of the best-known finds of wulfenite in Helena was made at the end of the 1960s by the miner Erich Podojsteršek from Podpeca. The pocket measured several meters in length and produced hundreds of superb specimens, among which 20-40 cm plates covered with large truncated bipyramidal wulfenites and greyish calcite crusts were quite abundant. Because of small interest for mineral collecting in Slovenia at that time, most of these specimens found their new home in collections abroad.

In 2005 a research expedition encountered a new 3 m long pocket, which contained 27 cases of excellent carrot orange bipyramidal wulfenite specimens with snow-white coatings of fine crystalline calcite. These specimens are now on display in the Mining Museum in Mežica.
