Forekomsten ligger i nordlia av Lille Ulvskollen, om lag 500 m sørøst for enden av skogsveien. Tursti på vei mot Ulvskollen går gjennom gruveområdet. Det er her grøfter og en del dype dagskjæringer over en lengde på over 400 m i NØ-SV retning. Hovedgruva er lengst sør og består av en 36 m lang dagstrosse, ca. 1 m bred og inntil 6-7 m dyp. I sørenden er det en større åpning med bredde ca. 3 m og den er vannfylt. Det er her en sprekkesone og pegmatitt som går i Ø-V retning. Sør for denne er det en ny fyrsatt skjæring, ca. 5m dyp som er 20 m lang. Også denne stopper mot en pegmatittgang. Det er røsket litt i overflaten 15 m videre sørover. Malmsonen er dessverre ikke blottlagt i gruva og det er svært vanskelig å finne prøver med mineralisering på de dels overgrodde tipphaugene. Det finnes enkelte stuffer med tynne årer og små aggregater av magnetitt i epidot og omgitt av kvarts. Ellers opptrer en god del mørk hornblende og noe rødlig granat. Om lag 40 m mot NNØ fra det som betegnes som hovedgruva er det en ny dagskjæring /strosse som er minst 8 m dyp i sørenden. Den er ca. 44 m lang og dreier mot nord i de nordligste metrene. Bredden er 0.75-1 m. Heller ikke her er det blotning av malmsonen. Malmsonen forskyver seg tydeligvis mot øst videre nedover lia og neste skjæring er 20 m vest for den ovenfornevnte. Denne er opptil 10 m dyp, 20 m lang og gjennomsnittelig 1 m bred. Ingen ting tilgjengelig er blottlagt. Det er en rekke grunnere, men lange grøfter/skjæringer videre nedover lia. Disse er typisk 1-5 m dype og 10-30 m lange. Antakelig er det gjennomskjærende pegmatitter flere steder som gjør at det ikke er en kontinuerlig grøft hele veien. Helt lengst nord ser mineraliseringen ut til å tynne ut og består kun av tynne forgrenede kvartsårer med noe magnetitt omgitt av epidotomvandling. Her har det nok kun vært røsket og ingenting er produsert. Årenettverket har en NNØ retning (ca. 25 grader) og har et steilt vestlig fall.
