Vestre Skogen består av en rekke små drifter på kvartsganger med vesentlig pyritt og mindre mengder sinkblende og kobberkis. Gangene har generelt svært begrenset mektighet og utstrekning. Hovedgruva består av en 10 m lang og 1-4 m bred vannfylt dagstrosse. Det er en dypere synk i sørenden av skjæringen med omriss 2.5x2.5 m. Retningen på dagstrossa er nord-sør. Det er drevet på en 1.5 m bred kvartsgang som inneholder grovkrystallin kvarts med opptil 2-3 cm krystaller. Det er vanskelig å finne mineralisert materiale. Det er enkelte blokker som inneholder tynne (<= 1cm) årer av sinkblende med noe pyritt, samt spredte aggregater av de samme mineralene (Prøve BU0212.01-samleprøve). Det er aksessorisk kobberkis. Utenfor hovedgangen opptrer tynne kvartsårer i en epidotisert sidebergart som inneholder spredt pyritt og litt sinkblende (Prøve BU0212.02).

En liten grop som er 2.5 m lang, 1 m bred og 1 m dyp. Befinner seg i åpne furuskog på en stor flate. Mineralisering er knyttet til en 1 m bred kvartsgang som stryker i retning 292/80. Det er kun fattig impregnasjon og spredt pyritt og litt kobberkis i aggregater. I kvartsgangen er det ellers litt kullblende.

Innhugg i en liten ås, ca. 2 m langt, 1 m bredt og inntil 1.5 m høyt. Det er blottlagt en ca. 75 cm mektig kvartsgang med mye drusekvarts i dels 3-4 cm store krystaller og dels i kamstruktur. Det ble ikke funnet sulfider og ble derfor ikke prøvetatt.

En liten skråsynk i vestsiden av trang liten dal. Synken er vannfylt 2 m inne. Høyden er 3 m der den faller nedover, mens bredden er 1 m. Tippvolumet er 10-15 kbm, noe som viser at synken er kort. Retningen er rett mot vest parallell kvartsgangen som har vært brutt. Denne gangen er omlag 40 cm mektig ytterst, men smalner innover i synken. Det er flere generasjoner med kvarts, som dels er drusekvarts. Det er litt kullblende. Det er svært lite sulfider å finne, kun enkelte korn av pyritt og sinkblende i drusekvarts. Sidebergart er forholdsvis massiv amfibolitt.

En 3 m lang, 1 m bred og 1 m høy skjæring inn i skrent i østlig retning. Innerst i skjæringen er det to parallelle kvartsganger som begge er 30 cm mektige. Kvartsen opptrer i kamstruktur og opptrer i dels 5-7 cm store krystaller. Mellom årene er det 10 cm med massiv kvarts. Mineralisering består av svært spredt pyritt, kobberkis og sinkblende nær yttergrensen av kamstrukturene. Mot sidebergarten som er finkornet amfibolitt er det epidotisering og tynne kvartsårer.
