(Krzemianka, Powiat Suwalski, Podlaskie, Polska)
Titanomagnetite deposit with dispersed sulphide mineralization. Fe-rich "Thiospinel" (Fe3S4) is mentioned by some authors, thus greigite is also included in the mineral list. Ag-Pt-Pd-Te-Se mineralization was detected in drill holes, also from other closely located places.
