Structure name In The Quetico Subprovince Of The Superior Province.

Controls for ore emplacement

  • Local Brecciation. Sims And Day (1992) Note That The Fundamental Regional Control On Gold Deposits In The Superior Province Is Transcurrent And Oblique Slip-Shear Deformation Zones That Formed In Late Archean Time.

Comments on the geologic information

  • PRECIOUS METALS MAY OCCUR BETWEEN DIABASE AND SLATE IN A BRECCIA ZONE CEMENTED BY QUARTZ AND CARBONATE AND SOME PYRITE.

Economic information about the deposit and operations

Comments on development

  • EXPLORATION FOR GOLD DEPOSITS IN THE REGION HAS BEEN HAMPERED BY A GENERALLY THIN, DISCONTINUOUS MANTLE OF PLEISTOCENE GLACIAL DEPOSITS. ; ECON.COM: THIS PROSPECT AND THE SPALDING MINE OCCUR IN THE ROVE SLATE AREA WHICH HAS HAD A LARGE SILVER PRODUCTION ON THE CANADIAN SIDE OF THE BORDER.
