Forekomsten ligger 4 km nord for Gjersvika, mellom Tjiermejaevrieh (Kirmavannene) og Austvatnet. Området er i stor grad dekket av løsmasser og bevokst med glissen bjørkeskog. Mineraliseringen er en basemetallfattig sulfidsone. Det er tre skjerp over en lengde på 300 m langs denne sonen. EM-målinger viser at den ledende fortsetter med mindre brudd ytterligere ca. 1 km sørvestover. Den er trolig en fortsettelse av Annlia-sonen som går langs østsida av Annlifjellet (forekomst NT0307). Ca. 500 m nord for forekomsten finnes en ny leder med liknenede mineralisering. Denne er kallt Kirma vest og kan følges 250 m. Sulfidsonen er opptil 1 m mektig. Tektonostratigrafisk over denne opptrer en få meter mektig kvartskeratofyr som er intrudert av kvartsporfyr. Over denne følger lys grønnstein, mens mørk grønnstein ligger under sulfidsonen.

Abstract:
Lok. Nr. 30499, 30492. Elektrisk-magnetiske målinger ble utført i Joma og Kirma. Det ble tilsammen målt 5,5 km2 i profiler på ca. 100 m lengde. På begge steder ble det påvist en rekke gode ledere utenfor de fra før kjente malmkroppene.

Abstract:
Ore occurences of the Grong area: In the period 1910-1918 a great number of ore occurences were discovered in the Grong area. The late state geologist Steinar Foslie mapped the area in the years 1922-1931. Foslie also mapped all claims and occurences and made special field investigations in a few cases. This book presents a survey of all occurences chiefly based on the field observations of Foslie. In addition the present author has done some field work in connection with the three large deposits, Joma, Skorovass, and Gjersvik. The map, Plate 1, shows the areal geology and the location of the occurrences, numbered from 1 to 131. the ore of the occurrences is chiefly pyrite. The larger occurrences also contain some chalcopyrite and sphalerite etc. and the smaller occurrences contain ither pure pyrite with some magnetite. The Joma deposit (No. 1), contains about 15.5 mill. tons of ore. The ore zone forms an arc and is situated within a thick series of greenstones (Fig. 1). The Skorovass mine (No. 2), contains about 7,5 mill. tons of ore. The deposit is situated in a greenstone complex (Fig. 7), and is immediately surrounded by asid tuffs of quartz keratophyric composition (Table 1).
