Dette er den største påviste forekomsten på Transtaulhøgdi. Enkleste adkomst er via en bomvei fra Tveitgrendi nordvest for Kviteseid. En sti fra denne fører fram til Johnsli seter som ligger ca. 450 m SØ for gruva. Forekomsten ble påvist midt på 1880-tallet og ble sporadisk drevet fram til 1910. Siste driftsperiode skal ha vært fra 1916-19. Ca. 20 m lavere enn dagskjæringer på øvre nivå går det inn en stoll med retning 18º. Ut i fra denne stollen går det tverrslag ca. Ø-V som følger mer forskifra soner i bergarten. Totalt er det ca. 5-600 m3 tippmasse. Ved inngangen til den nedre stollen finnes en finkornet, amfibolitt med foliasjon 271º/30º, mens massiv, lys grågrønn intermediær? metavulkanitt dominerer ovenfor i blotninger mellom arbeidene. Mineraliseringene ser ut til å være knytta til deformasjonssoner i denne bergarten. Den forskifra sonen inne i stollen har orientering120º/50º, mens en skifrighetssone ved de øvre skjæringene har retning 170º/70º. Det er imidlertid vanskelig å få et godt inntrykk av malmsonen utbredelse og dannelse. Det er ikke en kvartsgang forekomst som er mest vanlig ellers i området. Kraftig arsenkis disseminasjon opptrer i metavulkanitt med amfibolnåler og i kvartsittisk bergart. Kobberkis er mer vanlig i grønnskifer. Mineraliseringen er tidligere også beskrevet som uregelmessige, med mektigheter fra 0,15-1 m (Bugge & Foslie 1922).

Abstract:
Approximately 115 mines and claims have been examined in the years 1941-1961 during regional geological mapping of the Kviteseid quadrangle. The map area covers a part of the "Thelemark-Sætersdal ore province" established by prof. J.H.L. Vogt in 1886. The oldest mine in the area, opened in the year 1524, was worked for silver bearing chalcopyrite and bornite. Other mines have been worked for gold, native copper and silver, molybdenite, galena, arsenopyrite, bismuthinite. All the mines have long since been abandoned and most of the surface workings are overgrown and difficult to find. The 15 native copper and silver deposits (which also contain vanadium minerals) form a separate group. They are all situated along the contact between a sandstone and an overlying basalt, the ore being confined to the sandstone. Most of the other deposits are of Quartz vein type. In quartzites which cover the greatest part of the map area, most of the quartz veins are barren. The great abundance of ore minerals in quartz veins in basic lavas and basic sills may be due to favourable pH conditions in these rocks. The galena deposits are found within a limited area close to a penetrating granite. The ore mineral paragenese in some of the deposits may have been formed under hypothermal to mesothermal conditions whereas other possibly originated at lower temperatures.
