Det befinner seg to mindre grøfter på Bjørndalsåsen. Her skal det også være en sulfidforekomst som kalles Skridua (TE 0394). Denne ble imidlertid ikke funnet. Det som regnes som hovedgruva er en 15 m lang grøft i tilnærmet Ø-V retning (308 grader). Den er 1m bred og 1-3 m dyp (dypest i vest). Det er svært lite mineralisert materiale å finne. Blokker består av drusekvarts med kun spredte korn av magnetitt. Ellers er det dels noe epidot og rødbrun granat. Om lag 80 m mot SV er en ca. 10 m lang vannfylt grøft i Ø-V retning (090 grader). Mineralisering består av enkelte små aggregater av magnetitt i tett amfibol-epidot-granat matriks. Granatene er 2-3 mm store er gule til grønne, dels euhedrale krystaller. |
