Kisgruva ligger ca. 220 m SSØ for Kobbergruva og består av en vannfylt synk med sidevegger på 12 x 4 m på østsiden av en brattskrent med massiv grønnstein. Tippmateriale er svært forvitret, men ser ut til å domineres av svært finkornet, massiv pyritt i chert-matriks. Tippen er stor og har et volum på ca. 2.500 m3.
