Mineraly wolframu to ferberyt, hubneryt i wolframit, który należy do grupy wolframitów. Celem tych badań byla ocena potencjalu skal do występowania wolframu. Mineraly te znalazly zastosowanie w przemyśle do produkcji stopów i uzbrojenia, węglików spiekanych, narzędzi odpornych na zużycie, elektrod spawalniczych, biżuterii, urządzeń elektrycznych i stopów metali ciężkich. Na podstawie obserwacji terenowych stwierdzono, że glównymi litologiami tego obszaru są lupek i granit z dużymi intruzjami kwarcytu. Intruzja kwarcytu zawiera mineraly wolframu. XRD ujawnilo cztery fazy mineralne: kwarc, ferberyt, magnetyt i kolumbit. Badania petrograficzne wskazują na obecnośc kwarcu w zakresie od 25 do 30% w lupku, od 65 do 70% w granicie, od 60 do 90% w litologii kwarcytu, wedlug oceny wizualnej i od 50 do 55% biotytu w lupku. Stężenie pierwiastków śladowych w kwarcycie pokazuje, że W wynosi 331371,85 ppm w stosunku do Cv wynoszącego 1 ppm, co wskazuje na wysoką mineralizację wolframu w tym obszarze. Zaleca się zatem uwzględnienie badań SEM w przyszlych pracach w celu rozszyfrowania struktury i mineralogii rudy.
