Access Description: The Martin Bird property is located approximately 6 km south of the hamlet of Larder Lake along Hwy 624 and 3 km east along a gravel access road.

Exploration History

The original property was composed of 32 claims. The Martin-Bird Syndicate trenched the property in 1933 and began shaft sinking in 1934. Martin-Bird Gold Mines, Limited, was organized in 1936 to develop the property. Exploration and development continued until 1939, by which time, two 400-foot deep shafts were developed with levels at 125, 250 and 375 feet, and a total of 10 301 feet of drifting, 5179 feet of crosscutting and 319 feet of raising were completed (Thomson, 1947). The company held the property until the 1970's when it was acquired by R.A. MacGregor. A number of exploration programs have taken place since that time, including geological and ground geophysical surveys, overburden stripping, rock and humus sampling and diamond drilling.

Geology Comments

Dec 07, 2005 (D Guidon) - The property is underlain by clastic sedimentary wacke and argillite of the Timiskaming Group intruded by feldspar porphyry dikes and lies within a major northwest-trending syncline that has been overprinted with a series of northeast-trending crossfolds. The rocks are similar to the Timiskaming sedimentary rocks along the Cadillac-Larder Fault Zone (CLFZ) but lack jasper and trachytic voclanic rock fragments. The vein zones of the deposits lie within a strong shear zone that trends 060o. The shear zone may be related to a southwest-trending splay off the CLFZ to the southeast of the vein zone. In the vicinity of the deposit, the foliation changes to a northeast strike direction (Tims, 1995 - Assessment File KL-3752).).

Lithology

Lithology Comments

Dec 07, 2005 (D Guidon) - The property is underlain by clastic sedimentary wacke and argillite of the Timiskaming Group intruded by feldspar porphyry dikes and lies within a major northwest-trending syncline that has been overprinted with a series of northeast-trending crossfolds. The rocks are similar to the Timiskaming sedimentary rocks along the Cadillac-Larder Fault Zone (CLFZ) but lack jasper and trachytic voclanic rock fragments. Exploration has identified 3 auriferous zones over a strike length of 900 m. The surface exposure of the No. 1 zone near the No. 1 shaft reveals 2 discontinuous quartz-carbonate veins, approximately 1 m wide each, separated by about 4 m. Contorted, fine grained sedimentary rocks are cut by lamprophyre and boudinaged syenite dikes. The veins are surrounded by a carbonate-pyrite alteration zone.

Mineralization

Mineralization Comments

Dec 07, 2005 (D Guidon) - Near the No. 1 shaft, the minerlaized zone is exposed at surface. The main quartz zone is surrounded by a carbonate rich zone with pyrite. Zones are up to 3 m wide. The veins are discontinuous and trend about 055-90. There are 3 main quartz veins SW of the No.1 shaft.

Alteration Comments

Dec 07, 2005 (D Guidon) - The main quartz zone is surrounded by a carbonate rich zone with pyrite. Zones are up to 3 m wide.
