| Forekomsten er kjent som Tupajervi eller Stuevann-stollen og ligger like ved veien gjennom Porsangmoen skytefelt. Det er drevet en 20m lang stoll med korte tverrslag innerst til begge sider. Den ble undersøkt i detalj i 1967 (Juve 1968, Røsholt 1969). Forekomsten er muligens av samme type som "Algascåkka" FI0061. |
