Golden Gate Mine (Past Producer)


Au, Ay


Approximately 4 miles southwest of Kirk land  Lake,  north  of Otto  Lake,  in  southern  Teck Township  and  northern Otto Township. Shafts  in patented  claim  T2692  (old  Lucky  Cross  Mine)  in Teck  Township  and  patented  claim  L9592  (old Swastika  Mine)  in Otto Township. Village of Swastika occupies part of the property. Latitude 48.11 0, Longitude 80.100 . Map reference: ODM 1945-1, Township of Teck.


The  property  is  underlain  by  Keewatin metavolcanics, Timiskaming metasediments (includ ing tuffs),  carbonates,  various types of felsic intru sive rocks and later diabase and lamprophyre dikes. At the  Golden  Gate  Mine, the  veins  lie  in an area where  many  irregularly  shaped  bodies  of  syenite porphyry  intrude  the  mafic  metavolcanics.  The veins  trend  approximately  N530E  and  dip  steeply north.  They  have  been  cut off by  a  wide  zone of faulting, known as the “A” Fault, which dips450S. The  productive  veins  have  not  been  found  on  the footwall  side  of  the  “A”  Fault  where  another approximately  parallel  fault with  a  slightly steeper dip occurs. This fault,  known  as  the Valley Faujt, was  mapped  at  surface  in the northern part of the property  as  a  strong  shear  zone  with  siliceous carbonate  alteration  located  at  or  near  the Timiskaming-Keewatin  contact. The  Valley  Fault  is  the continuation  of the  Larder  Lake  “Break” west  of the  Amikougami  Creek  crossfault.  Underground diamond-drilling  intersected  green  carbonates  and quartz  stringers with  low gold values  in the Valley Fault. Geological conditions at the Crescent Kirkland Mine (old Swastika Mine)  are quite similar to those at the Golden Gate Mine. The rocks in the mine workings consist  of  Keewatin  metavolcanics  intruded  by  ir regularly shaped  bodies of diorite, granodiorite, and lamprophyre. Quartz veins intersect all these forma tions.  The  vein  quartz  is  locally  mineralized with pyrite and small amountsof galena and molybdenite. The entire vein zone has been badly disturbed by a system  of  post-ore  faults;  the  strongest  of  these strike  northeast  and  are  close  to vertical.  Because gold  values  occur along certain of these structures, either  some  of the  movement  may  have  been  pre- ore or some gold deposition occurred later than that of the main veins.

a) of the old Swastika (Crescent Kirkland) Mine:

1908-1912:  Gold discovered in claim T9592. Three- compartment shaft (Golden Gate No.3) to 400 feet and  approximately  3,000  feet  of  underground development  on  levels  at  35,  100,  200,  300,  and 400  feet.  Two-stamp  mill  installed  in  1909  and some  ore  milled; five-stamp  mill  installed  in  1911 and  520  tons of  ore  milled; ten-stamp  mill  under construction  in  1912  but probably  never  finished. All work by Swastika Mining Company Limited.
1936-1939:  Underground  workings  dewatered,  re conditioned,  and  sampled,  1,512  feet  of  lateral development,  1,866 feet of underground diamond- drilling,  4,584  feet  of  surface  diamond-drilling and  2,000  feet  of  surface  trenching  by  Crescent Kirkland Gold Mines Limited.

Underground opera tions suspended in April 1942.
1943-1944:  Considerable  surface  diamond-drilling by Golden Gate Mining Company Limited.
1945: 434 feet of underground development on the 100-,  300-,  and  400-foot  levels  and  five  surface diamond-drill  holes  (4,800  feet)  by  Golden  Gate Mining Company Limited.
1946-1949:  Golden  Gate  No.3 Shaft deepened  to 676 feet with new levels at 525 and 650 feet, 6,477 feet  of  underground development and  164  under ground diamond-drill holes (31,849 feet). Some ore milled  in  1947.  Work  by  Kirkland  Golden  Gate Mines  Limited.  Underground  development  to December  31,  1948 totalled 4,780 feet of drifting, 6,979 feet of crosscutting and  982 feet of raising. Mine closed in 1949. 171

b) of the old Lucky Cross Mine:

1910-1912:  Gold discovered  in claim T2692. Shaft (Golden Gate No.1),  inclined 650,  to 200 feet with at least 800 feet of lateral development on the 100- foot  level.  Five-stamp  mill  erected  and  some  gold recovered. Work by Lucky Cross Mines Limited.
1915-1916: Works dewatered and 200 feet of lateral development  on  the  100-foot  level  by Tretheway Silver-Cobalt Mining Company Limited.
1922-1923:  Shaft  deepened  to  360  feet,  lateral development on the  100-, 200-, and 350-foot levels, and  diamond-drilling  by  Kirkland  Gateway  Gold Mines Limited.

Work by Golden Gate Mining Com pany  Limited.  Mine  and mill closed  in April  1942.

c) of work on both properties after consolidation:

1941-1942:  118  underground  diamond-drill  holes (14,242  feet),  13  surface  diamond-drill  holes (2,786 feet),  and  500 feet of trenching by Golden Gate Mining Company Limited.
1950:  Nine  diamond-drill  holes  (5,658  feet)  by Gateford Mines Limited.
1974:  Geophysical surveys and diamond-drilling by Gateford Mines Limited.
1975:  Surface  work  and  diamond-drilling  (10,548 feet) by Dickenson Mines Limited.

Please  note:  The  above  information  was  compiled from  accounts  given  in ODM Annual  Reports. The accuracy of some of the data, particularly for work performed prior to  1920,  is suspect due to obvious discrepancies  between  references  which  could  not be resolved.


Year Lucky Cross Section Swastika Section
Value  Ore Milled Value  Ore Milled
(dollars) (tons) (dollars) (tons)
Prior to 1922 $14,006 2,500 $11,457 2,190
1933-1937 $175,277 11,376
1939-1942 $765,415 75,074 $51,977 6,265
1943-1944 $2,340 Cleanup
1947 $42,507 6,288
Total $957,038 88,950 $105,941 14,734

Thus total production from the two properties was S1.062,979 from  103,684  tons of ore. This agrees very well with the figures given for Kirkland Golden Gate  and  Swastika  in  ODM  1954,  Vol.63,  pt.1, p.13 and  14, respectively.  It  is  not possible to give production  in  terms  of  the  amounts  of gold  and silver,  since  most  annual  production  was  reported only  as  a  dollar figure.  However,  it  is  known that the  average  recovered  grades for the  Lucky  Cross and Swastika sections were 0.31  and 0.21  ounce of Au  per  ton  respectively,  for  an  overall  weighted
average recovered grade of 0.29 ounce of Au per ton.
