Economic information

Geologic structures

Type of structure Regional
Structure name In The Quetico Subprovince Of The Superior Province.

Controls for ore emplacement

  • 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

  • THE MAIN ORE IS A CHALCOPYRITE-PYRRHOTITE SEGREGATION IN A DIABASE INTRUSIVE, WITH LOCAL REPLACEMENTS AT HIGH TEMPERATURES FORMING MASSES OF XONOLITE, PREHENITE, AND SULFIDES. THE DIABASE NEAR THE MASSES SHOWS SULFIDES WIDELY DISSEMINATED IN THE ROCK. THESE INCLUDE PYRRHOTITE, CHALCOPYRITE, WITH SUBORDINATE, CUBANITE, PENTLANDITE, AND VIOLARITE. GROUT (1937) NOTES THAT THE MORE MASSIVE REPLAEMENT ORES ARE HYDROTHERMAL REARRANGEMENTS OF THE MATERIAL OF THE SAME MAGMA AS THE PRIMARY SULFIDES.

Economic information about the deposit and operations

Commodity type Metallic
Deposit size Small
Significant No

Comments on the workings information

  • PROSPECT PITS WERE OPENED FOR NICKEL AND COPPER, BUT ARE SAID TO CARRY SOME VALUES IN GOLD.

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: THE OCCURRENCE OF LARGE GOLD DEPOSITS IN CANADA SUGGESTS THAT THE GREENSTONE-GRANITE TERRANES OF MINNESOTA ARE FAVORABLE FOR THE OCCURRENCE OF IMPORTANT GOLD DEPOSITS.
