| Description |
| Kleppe-forekomsten ligger 350 m SV for Smørknatt. Den er drevet med en synk og en rekke grunnere skjæringer over en lengde på ca. 90 m i hovedsakelig NØ-SV retning. Synken er drevet ned i kanten av en høy skrent, er 3x4 m i omriss og vannfylt. I følge gammel bergarkivsrapport skal den være 25 m dyp med noen tverrslag i bunnen. Den overgrodde tippen utenfor synken har et volum på 3-400 kbm. I synkveggen er det pegmatitt med enkelte, spredte korn med molybdenglans. Det enkelte linser/lag med lys amfibol-biotittskifer og det kan se ut som mest molybdenglans er tilknyttet disse. Det er for øvrig lite å se her. |

| Description |
| I dette området er det laget en rekke grøfter og grunne røsker over et område på ca. 30 x 30 m i utstrekning. Det er også to dypere hull (5-6 m?) som er dels gjenfylt av sprengt materiale. Også her ser det ut til at molybdenglans i hovedsak ligger på eller nær kontakt mellom amfibol-biotittskifer/-gneiss og pegmatitt, typisk sammen med kvarts. Det er også enkelte spredte korn inne i pegmatitten. |
