Varglibusta består av to mindre skjerp i form av vannfylte skråsynker. De ligger begge på skoggrensen noen få hundre meter over setrene på Prestvollen. Det øverste skjerpet ligger lett synlig like over tregrensen og består av en vannfylt skråsynk med åpning 5x4 m og faller i vestlig (265°) retning med fall som omgivende bergarter. Tippvolumet er ca. 40 m³. Mineralisering består av mm- til cm-tykke årer og linser av magnetkis, kobberkis og noe pyritt. Årene/slirene opptrer parallelt foliasjonen i bergarten og inneholder sulfider i form av spredte streker til semimassive årer av vesentlig magnetkis. Bergarten er kloritt-kvarts- sericittskifer med hyppige mm-store "gryn" av lys gul feltspat.

Skjerp II ligger ca. 150 m NØ for nr. I, like nedenfor skoggrensen. Den vannfylte skråsynken har en åpning på 4x2 m og faller slakt mot vest (retning 245°). Tippvolum ca. 60 m³. Det er gjengrodde små røsker 7-8 m unna på hver side av synken. En annen røsk 1 x 0.5 m og 0.5 m dyp finnes 45 m SV for synken. Mineralisering består av uregelmessige slirer opptil 1-3 mm tykke, parallell foliasjonen av kobberkis og stedvis noe magnetkis i sericittisk kvarts-klorittskifer. Ved synkåpningen opptrer svært klorittrik skifer med streker av kobberkis og lokalt anrikning av mm-store granater.
