Gullforemsten ved Sibirien i Grong kommune, Nord-Trøndelag, er knyttet til en inntil 200 meter bred og mer enn 3 km lang "sverm" av kvartsårer som skjærer gjennom prekambriske gneiser langs nordkanten av Grong-Oldenkulminasjonen. Kvartsårene fører sporadisk sulfider, i hovedsak grovkornet pyritt, kobberkis med bornitt, og lokalt blyglans. Gull opptrer som små inneslutninger og sprekkefyllinger bare i sulfidene, og selve forekomsten viser en rik, men svært lokal, sulfidanrikning innenfor enkelte av kvartsårene. Sulfidrike prøver inneholder inntil 78 ppm gull. Det er ikke funnet gullanrikninger hverken i rene kvartsårer eller i forskjellige typer sulfidimpregnasjoner i området, og heller ikke i de umiddelbare sidebergarter til de sulfid-førende årene. Omfattende undersøkelser med geologi, fastfjellsgeokjemi, løsmassegeokjemi, geofysikk (IP) og kjerneboring har vist at Sibirienforekomsten ikke er drivverdig. Blant 11 borhull er høyeste gullinnhold 0,8 ppm, regnet i gjennomsnitt over 2 m mektighet, og flere av borhullene viser ingen gullanrikning. Det er heller ikke grunnlag for å foreta videre undersøkelser i nærområdet omkring Sibirienforekomsten.
