Det er svært lite å finne i NGUs Bergarkiv om forekomsten. Den skal være oppdaget før 1885. Forekomsten ble ikke funnet under malmregistreringen i 2007. I følge lokale folk er det gjort svært beskjedne arbeider på lokaliteten. Koordinatene er foreløpig lagt på tømmerhytta nede ved veien som skal være like ved forekomsten. Fra Dons 1963: Forekomsten ligger ca. 300 m øst for gården Aa i Høydalsmo. Den ligger like ved veien hvor det nå er en tømmerhytte. Det er bro over hovedelven like ved. Mineraliseringen skal i følge Dons (1963) bestå av kobberglans (spor) i en 0.5 m bred kvartsgang i porfyrisk grønnstein. I en gjenfylt kabelgrøft ble det funnet en rekke kryssende kvartsganger.

Abstract:
The ore fields and individual deposits which are mentioned in the text are shown on the map, figure 2. For those areas where the deposits lie so close together that they cannot be shown separately on this map, detail maps have been drawn on larger scales. In the descriptions there will also be found special maps covering the most important molybdenum areas. An index of the deposits which are mentioned is arranged both alphabetically and according to the numbers on the map. The majority, including the most important, of the ore deposits in Southern Norway lie within a marked zone, which is shown on the map, figure 3. At varying periods of time different metals have characterised the long zone of ore deposits: titanium in the southwest, then molybdenum in the area from Gursli to Knaben, copper and molybdenum in Telemark, silver, zinc and lead from Kongsberg eastwards, and further to the east, molybdenum again. From the map, figure 4, it can be seen that the most important groups of deposits are situated to both sides of the granite-gneiss area of the mountanious region of Southern Norway and that they lie in migmatised gneisses along the southwest side and in the schists and quartzites of the Telemark supracrustal suite along the northeast side.
