To mindre stoller er drevet ca. 775 moh., rett øst for enn en sti som fører fra hyttefeltet og nordover opp langs Geiteryggen. De ligger i rødlig, svakt foliert, porfyrisk granitt med molybdenglans sammen med biotitt langs cm-tynne, pegmatittiske kvarts+feltspatårer. Denne mineralisering er en av mange mindre molybden-mineraliseringer som er beskrevet fra Reinshommen-området hvor bare mindre skjerping og prøvedrift er utført (Smith 1934, Bugge 1963).

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.

Abstract:

Rapporten beskriver resultatene etter en befaring, og omtaler geologi, malmens karakter, gehalt og forekomsttype, samt gir en beskrivelse av gruvefeltet. Malmhorisontens utstrekning anslås til mye over 1 km etter strøket og minst 600 m i bredde. Rapporten konkluderer med at "Reinshommen molybdenfelt gjør krav på energisk oppfaring".
