Denne mineraliseringen er i hovedsak blottlagt i en 10 m lang, grunn røskegrøft ca 1 km opp fra elva i Mosvassdalen. Mineralseringen består av striper av dels rik pyritt-impregnasjon, lokalt anriket i sinkblende i kvarts-sericittskifer. ASPRO prøvetok over hele grøftas lengde og over 4 m ble det analysert 0.49 % Zn, 0.32 % Cu, 0.06 % Pb, 23.3 g/t Ag og 0.2 g/t Au, hvorav 1 m med 1.19 % Zn, 0.17 % Cu, 0.14 % Pb, 47.2 g/t Ag og 0.9 g/t Au. Totalt kunne mineraliseringen følges over 500 m lengde langs strøket. Det ble sprengt ut prøver på ytterligere 6 lokaliteter langs strøket i sericittskiferen over 285 m, hvorav en prøve i grop 2, 95 m mot vest viste 4.36 % Zn, 0.67 % Cu, 0.17 % Pb, 32.1 g/t Ag og < 0.1 g/t Au over 0.5 m mektighet. Dette var i en foldeombøyning. De andre prøvene viste 0.05-0.40 % Zn, 0.03-0.22 % Cu, 0.02-0.07 % Pb, 2.0-7.7 g/t Ag og <0.1-0.2 g/t Au. Kvarts-sericittskiferen er en omvandlet felsisk metavulkanitt (kvarts-keratofyr) som kan følges mot nordøst til området sørøst for Brunreinvann. Dette er samme vertsbergart som forekomstene ved Raudvatnet, Brunreinvann og Svarthammeren.
