I mange deler av Heilhorngranitten (Nordgulen og Schouenborg 1988) finnes duktile skjærsoner med utvikling av granittiske mylonitter. Disse kan følges opptil 1 km langs strøket som er NNØ-SSV til NØ-SV. Forekomsten ble funnet av Ø. Nordgulen under hans regionale undersøkelser av intrusiver i Bindals-batholitten. Den omfatter flere lokaliteter med sulfidmineraliserte mylonitter i fjellsiden ned mot nordbredden av Sørfjorden. Den mektigste av disse finnes langs Horndalen (ca. 70 moh.)som munner ut ved Osen på kbl. Austra (hovedforekomst). De andre lokaliteter finnes langs Østre og Vestre Nordelva på kbl. Terråk (1825-3). Horndalenforekomsten omfatter en 3 m bred sone av mylonittisk granitt som i de sentrale deler glir over i en serisittrik fyllonitt med disseminasjon og sulfidbelagte skjærplan av svovelkis, litt magnetkis, arsenkis og sannsynligvis vismutglans ifølge analyser. Sonen inneholder også skjærdeformerte kvartsganger med sulfidbelegg på skjærplan og tverrsprekker. Tilsvarende mylonittsoner, kvartsganger og mineraliseringstyper finnes også langs Nordelva , men disse har vanligvis mektigheter på 0,1-0,5 m, og inneholder vanligvis bare disseminasjon av svovelkis |
