Skarn iron ores. This locality has produced many classical dipyramidal smoky quartz (morion) up to 6-7 cm , amethysts, calcites and fluorite specimens.
Already in production in the 16th century but due to lack of manpower and equipment to keep the mine drained it was very intermittently operated until 1741. From then on it was mined continuously until 1865.
Note: Hesselkulla is the older spelling for the locality. Sometimes also called "Västra Hässelkulla" (Western) to distinguish it from the Hässlkulla copper mine.
