The Homsevatnet sulfide deposit is located in the north-central part of the Egersund-Ogna anorthosite about 12 km north-northwest of Egersund and is the most significant sulfide deposit in the province. Exploitation of the Ni-bearing sulphide ore took place during the early 1870s. Mining operations have left a 10-15 m long and 4 m wide incision in the anorthosite host and an 8 m deep shaft sunk into the main sulfide ore. The shaft is now filled with water.
The deposit is situated within massive anorthosite well away from the foliated and deformed margin of the body. The sulfides occur within a norite pegmatite intrusive into the Egersund-Ogna anorthosite.
A number of small and possibly related occurrences have been found in an elongated area covering 2 to 3 km2 around Bjørndalsnipa and Ualand, south of the Homse deposit.
