A gold prospect measuring 1x2 m.

The main ore minerals are arsenopyrite and pyrite and comprise up til 50% of the quartz vein which has a maximum thicknes of 0,5 m.

Exploration in the Espelandsmyr-Gjerstad area.
;ARCO Norway;RAPPORT;Report; No.84-23-38;38 s. + p pages
Abstract:
The Espelandsmyr-Gjerstad area is part of the Proterozoic Bamble belt. The rocks are in amphibolite or locally granulite metamorphic facies. The orientation of rocks is northeast-southwest with a steep southeast dip. Uncertain facing evidences indicate younging towards the east. The Espelandsmyr-Gjerstad area comprises a mixed volcanic-sedimentary rock package with exhalative features and a few younger granitic and gabbroic intrusives. The mineral occurrences in the area include: a) a stratabound Pb-Zn-Ag massive sulfide deposit of exhalative origin b) stratabound graphite and disseminated Fe-(Cu)-sulfides c) an epigenic As-Au-Cu vein deposit. None of the explored mineral occurrences has been of economic size or grade. The area still has a potential for both epigenetic and stratabound Au deposits.


The actual prospect might be 4,4 m to the NW, since this is the only feature in the vicinity of the NGU coordinates that can be recognized as a hole in the ground.
