Denne gruva ligger nær vannkanten om lag en kilometer nord for Haukaneset og Storåker som er enden av veien på østsiden av Varaldsøy. Det går en traktorvei nesten fram til gruva som nok dels har vært den gamle gruveveien. Gruva består av en 36 m lang stoll i vestlig retning. Det er to grunne synker mot sør henholdsvis 5 m og 15 m innenfor stollåpningen. Bergarten i området er en grønnskifer med hyppige kvartslinser. Malmsonen er blottlagt i stollveggen og i taket og er inntil 7-8 cm mektig ved den ytterste synken, ellers 1-3 cm. Den kan også følges ca. 30 m ned på strandblotningene foran stollen før den kiler ut. Mineraliseringen består av svært finkornet kobberkis med litt magnetitt og pyritt som dels opptrer i slirer og årer sammen med kvarts i mørk grønn kloritt. Ved den ytre synken er det også en foldet linse med massiv kobberkis. Foliasjonen i grønnskiferen er 100/30, og malmsonen følger denne foliasjonen.

Abstract:
When Steinar Foslie suddenly passed away in november 1951, he had finished the geological map here presented: "Kisdistriktet Varaldsøy-Ølve i Hardanger", based on field-work during 1942-49. Furthermore his M.S. contained a thorough petrological description of the rocks (p. 1f.) and the history of the copper-mining in the Ølve-district "Christiansgaves (Lilledale) kobberverk" from the two periods 1642-73 and 1759-85, holding a lot of items based on the study of records (p. 55 f.). These M.S. are printed unaltered, introduced by the author's own preface. The paper as a whole must be looked on as a basic draft only: An obviously planned section treating the ore deposits and their mineralogy has not been worked out, yet the facts presented may throw light upon general problems connected with the pyrite-deposits of Norway. As appears from the map the predominant rock in the pyrite-district is greenstone, more or less schistose. The term "greenstone" is here used for basic lavas and tuffs only, while the designation "the greenstone formation" is used by Foslie in the same sense as for the widely extended pyrite-bearing group in the Trondheim-district.
