Upper Canada Mine (Past Producer)

MAIN METALS: Au, Ag

LOCATION:  Approximately  9  miles  east  of  Kirkland Lake,  1^  miles  west-southwest  of  Little  Larder Lake,  in  central  Gauthier  Township.  All  claims patented.  No.1  Shaft  in  claim  L6314;  No.2  Shaft in  claim L6321. Exploration shafts in claims L6316, L15584,  and  L15585.  Latitude 48.140 ,  Longitude 79.820 . Map reference: ODM 50c, Township of Gauthier.

GEOLOGY:  In  the vicinity of the mine workings, east- northeast-trending  Timiskaming  metavolcanics (trachytic  breccia  and agglomerate)  are overlain by Timiskaming  metasediments  (greywacke  and  con glomerate)  on  the  north  limb of  a  major syncline. These  rocks  are  intruded  by  Algoman  porphyry bodies  and  later  diabase  dikes.  Much  of the  pro perty is covered by sand and swamps. The  o re bodies  occur  along  a  wide zone of schisto sity which strikes east-northeast through the centre of the  property.  The  core of this zone  is occupied by the  Upper Canada “break”, a system of narrow gouge-filled fractures in highly altered tuff, trachyte, trachyte porphyry, and syenite porphyry. Alteration consists  of  carbonatization,  sericitization  and  sili cification.  Gold  occurs  in  relatively  late  fractures in silicified zones and pyrite.

ECONOMIC  FEATURES:  The  orebodies  occur  in  six vertically dipping  main  vein  zones:  L,  H,  B,  C,  M and  K.  The “L” zone,  striking  east  and  having an average  length of 1,800 feet, was the strongest and most  productive  ore  zone  in  the  mine.  It  is  con tinuous  from  surface  to  the  deepest  level  of  the mine.

OWNERSHIP: Upper Canada Resources Limited.

HISTORY:

Early 1920s: Surface trenching.
1928:  Surface work, shaft (Upper Canada No.1) to 134 feet, and some lateral development on the 125- foot  level  by  East  Main  Gold  Mines  Limited. This work resulted in the location of the “M” zone.
1936-1941:  “H” zone located by surface diamond- drilling.  No.1  Shaft  deepened  to  1,000  feet with levels  at 125-foot intervals by Upper Canada  Mines Limited.  “L”  zone  located  by  surface  diamond- drilling.  To  develop  this,  No.2  Shaft  (2,900  feet west of No.1 Shaft) was sunk.
1941-1972:  Levels  opened  from  No.1  Shaft  to  a depth  of 3,625 feet; subshaft  below  No.1  reached a  depth  of 6,296 feet. No.2 Shaft reached  a depth of  1,877  feet.  Drifting,  crosscutting,  and  raising totalled  170,364,  44,399,  and  52,313  feet  re spectively.  Salvaging  completed  and  mine  closed in 1972.
