Forekomsten består av to mindre skjerp som ligger øverst i Hendalen, øst for elva Stor-hena og ca. 600 m sør for hvor denne renner sammen med Veunda. Det er relativt mye overdekke i området. Det største skjerpet er en opptil 2 m dyp utsprengt grop på 2x2 m. 10 m øst for dette er et mindre skjerp på 1x1 m. I følge Aasgaard (1927) ble det skjerpet omkring 1913 på en svovelkisgang som er 0.5-1 m mektig. Malmsona er ca. 0.5 m bred i hovedskjerpet. Prøver fra tipphaugene viser at malmen består av massiv til semi-massiv svovelkis i kvartsrik grunnmasse og massiv magnetkis med spor av kobberkis. Den opptrer på grensen mellom relativt massiv, kvartsrik biotittskifer og finkornet amfibolitt. Området ligger rett øst for Fongen-Hyllingen massivet, og bergartene gjennomsettes hyppig av dolerittiske og trondhjemittiske ganger.

Abstract:
The occurences described in this paper form a connection between th mining districts around Røros to the south and those around Meråker to the north. The occurences lie in mountain regions partly above the forest line. The list on page 12 contains the names of all known occurrences of whatever size within the district considered. Pl. I is a geological outline map of the district, compiled from maps in the Norwegian Geological Survey. In a geological summary on pages 18-27 it is shown that no pyrite occurrences of economic importance so far have been found in an eastern zone along the Swedish boundary where the rocks consist of hard schist with sparagmites, and igneous rocks. Neither have such occurrences been found in a zone of "Stuedalsskifer" and an other zone of "Gulaskifer" towards west, both indicated on the map. The occurrences of pyrite are chiefly found in connection with fine grained, light green or gravish, partly feldspar bearing schist and in connection with green schists, mostly fine grained hornblende schists. All these zones of schist gnereally strike north and dip west. The pyrite bearing schist lie on both sildes of a large zone of igneous rocks extending from Kjølifjell in the south over Hyllingen and Melshogna to Fangen in the Meråker district in the north.
