Forekomsten ligger vel 100 m øst for gården Ruene på toppen av brattskrenten ned mot Glomma i øst. Arbeidene består av en 25-35 m lang og 3-4 m bred dagskjæring med opptil 6-7 m høye vegger. Den har retning 355 grader og i den sørlige enden finnes en vannfylt synk. Ifølge Rekstad (1921) skal det ha vært to synker og malmen inneholdt omtrent 1,5 % nikkel. Gruva ble drevet av Glørud interessentskap fram til 1876, ned til ca. 15 meters dyp hvor malmen tok slutt. Sulfidmineraliseringene domineres av uregelmessig disseminasjon og aggregater av magnetkis, kobberkis og pyritt i middels- til grovkornet metagabbro. I tillegg er det i nordveggen synlig en 20-30 cm bred sulfidsone med massiv til semi-massiv magnetkis middelskornet metagabbro. Rett øst for inngangen til skjæringen finnes flattliggende granittisk gneis og det ser ut til at sulfidmineraliseringene opptrer langs kanten av metagabbro mot kontakten til sidebergarten. Tippen er spredt nedover brattskråningen mot Glomma og det er vanskelig å anslå volum, men det er klart at det har vært ganske betydelig drift i denne lokaliteten. Ifølge Norges Bergverksstatstikk produserte Glørud interessentskap nesten 2.000 tonn nikkelmalm i perioden 1875-77, trolig fra flere forekomster i området (f.eks Glørud). Fire prøver av representativ mineralisering innsamlet i 2025 inneholder 0,5-3,6 % Ni.

Abstract:
The territory is situated in south-eastern Norway to the east of the Oslofjord. It is an inland district which at no place reaches the sea. Glomma is the chief river which runs through the country in a southerly direction. The rocks occurring here are gneiss, granite, gabbro and schistose amphibolite, all of them of Archean age. Gneiss occupies a large area of the region. The rock has a varied appearance. Partly it is rich in mica (mica gneiss), partly it contains hornblende (hornblende-gneiss), partly it is coarse-grained and of granitoid texture. This latter form embraces also granite which has been deformed by powerful mechanical forces. This granite is intermixed with the gneiss in such a way as to make it impossible to separate them on the map. For the most part there is no distinctive demarcation between them, but the one passes into the other. The gneiss is mostly stratified, with well defined strike and dip. The granite intermixed is younger than the gneiss, but it belongs to the oldest known granites of Scandinavia. The gneiss is for the most part of igneous origin. Gabbro and amphibolite occur as numerous lenses injected into the gneiss. Connected with the gabbro here occurs nickelferous pyrrhotite. The greatest of these occurrences is at Romsås.
