| Denne malmhorisonten ligger over, øst for, Varrevannsmalmen og består av malm av Tverrdalstypen med ca. 20 % Fe magn. Den kan følges over ca. 3 km lengde og er opptil 20 m mektig. Ved UTM 388650 7721900, like ved stien, er det en 15 m lang, gjengrodd røskegrøft uten tipp. Blotning i ryggen like ved mot sør av 20 - 25 m mektig finkornig kvartsbåndet magnetittmineralisering (prøve 01) med tilnærmet umineraliserte partier av amfibolitt og kvartsitt. Båndingsretning i mineraliseringens østside er 335°/50°, og i vestsiden 155°/90°. |
