I følge Vokes & Vrålstad (1969) lå dette skjerpet lder hvor veien til Ulleren krysser elva fra Væleren. Skjerpet ble gjenfylt på slutten av 60-tallet og det finnes ingen blotninger i dag. Forekomsten ligger i kontakten til Heieren mafisk-ultramafisk intrusjon.

Abstract:
Sommerens arbeide har gitt en meget god innsikt i opptreden av de Ni-Cu førende sulfidiske forekomster i en betydelig del av Ringerikes nikkelmalmprovins. Arbeidet, som har vært av rekognoserende natur pga begrenset antall medarbeidere og tid, har ført til forståelse av forekomstmåte ved de fleste viktige gruver og skjerp. Omtalte og befarte forekomster: Grefsrud skjerp, Ertelien, Skjerpevik gruve, Kauserud skjerp, Ullentjern skjerp, Orretjern skjerp,Skog (Skaug) gruve, Tysklands gruve, Langedals gruve (inkl. Bekken og Støvern gruver), Støverntangen gruve. Fins også i BV-arkivet (DMFs database for undersøkelsesrapporter) merket BV 1345.

This pit is located at the SE extreme of the grassland near the Langdalstjønna lake. It consists of a 6H5m trench, 2-5m deep. Pyrrhotite occurs occasionally in 2-3mm large grains in the gabbro/norite rock that occurs throughout the area in minor amounts. In a small tailings heap, massive coarse pyrrhotite in 1-2cm grains was found, together with millimetre sized magnetite and traces of chalcopyrite.
