Larsen (1993) beskriver den som kvartsganger med stedvis små mengder sulfider i en basalt som grenser mot syenitt, og at kvartsganger og svovelimpregnasjon i syenitten opptrer umidellbart nær grensen mot basalten. Videre er det funnet kvarts, kalkspat, kopperkis, svovelkis, sinkblende, blyglans og malakitt. I følge Larsen (1993) ble forekomsten funnet rundt 1885 og mutet i 1886 av kjøpmann A. C. Darre i Skien. Skjerpingsarbeidet ble trolig forestatt i perioden 1885-1890: En mindre dagstrosse og to synker.

Abstract:

On the map accompanying this paper all the mines and ore deposits of Southern Norway are collected for the first time.The material has been gathered from printed and unprinted sources, communications from mining engineers and geologists, and through personal visits. Included are all mines and ore deposits of former, present and future importance. Among the 1407 deposits on the map, there are furthermore included all of doubtful value and many which are quite unworkable, but of geological interest, or those which mark the distribution of ore bearing formations. For this reason it has been necessary to mark the deposits with signs of different size. The object is only to facilitate a comprehensive view of the map, and is not an effort of economic classification, which for most of them would be quite impossible. The sizes refer to the presumed importance of the ore deposit, and has nothing to do with the extent of the mining operations. Mines and deposits out of work during the period 1913-1923 have been separately marked (see the legend), also deposits which were formerly of much greater importance than now. For the smallest mines and deposits no distinction has been made in these respects. Among them are represented partly those, which are in reality unworkable, partly those which are little investigated.
