Exploration History

1928: trenching and 1130 ft of diamond drilling. 1948-1950: Diamond drilling by Matarrow Lead Mines Ltd. 1951-1953: Matachewan Consolidated Mines brought the property into production. Mine closed in February 1953 after 7 1/2 months of production. Ore on 300 foot level was less than expected. By the end of production, 51 surface diamond drill holes, totaling 13,891 feet, were completed. 1964-1965: New Jason Mines Ltd. tested mineralization below the old workings with 7750 feet of diamond drilling in about 18 holes. A ground VLF-EM survey was completed. 1968: Three additional diamond drill holes completed. 1996: Opawica Explorations Inc. completed line cutting, trenching, ground magnetic and IP surveys and a 6-hole 1077.6 m diamond drill program.

Geology Comments

Dec 07, 2005 (D Guidon) - The deposit lies within Late Archean mafic to felsic flows, tuffs, banded chert-magnetite iron formation and lithic wackes. The metavolcanic and metasedimentary rocks strike northeast and dip steeply to the southeast. They have been intruded by felsic plutonic rocks of the Round Lake Batholith to the south of the deposit. The late Archean rocks have been intruded by Late Archean Matachewan swarm diabase dikes. All the rocks are unconformably overlain by sedimentary rocks of the Early Proterozoic Gowganda Formation.

Lithology

Lithology Comments

Dec 07, 2005 (D Guidon) - The package is described as interbedded flows and tuffs, ranging in composition from acidic to basic, and containing a zone of banded iron formation slightly in excess of 60 m and exposed for a strike length of about 500 m. North of and underlying the iron formation, mafic volcanics and diorites have been described in the drilling. It can be massive, sheared with or without talcose alteration. The rocks to the south of the iron formation are sedimentary or tuffaceous. These are described as felsic and or cherty with chlorite and some sulphides. The iron formation is either suphide or chert-magnetite. Two quartz-carbonate veins are the host of the galena and sphalerite. The two veins are roughly parallel. The weaker north vein dips about 75 degrees south and the main vein is nearly vertical with a slight southern dip and strike about 065.

Mineralization

Mineralization Comments

Dec 07, 2005 (D Guidon) - The two quartz carbonate veins are about 3.5 m apart and range up to 1.2 m in thickness. Siphides are lean to massive, when the vein are thickest. The majority of the ore is galena with irregular deposits of sphalerite. Stringer of sphalerite, galena and calcite occupy fractures int he wallrock adjacent to the veins.

Notes: Property visited June 18 2002 and again August 29 2002. Samples: 02305 - banded qtz-carb alternating with fg sulphide and some chlorite (main vein). 02306 - near massive sulphide with minor qtz-carb veining (main vein). 02320 - banded chert-magnetite iron formation (near main vein). 02321 - near massive sulphide with chlorite and graphite (north vein). 02322 - qtz-carb vein with galena (dump). 02323 - galena rich stringer (dump). Photos: 730290 - banded magentite-chert zone (sample 02320). 730291 - close up of 73290. 730292 - north vein as exposed in trench east of main road (sample 02321). 730293 - close up of 730292. Assessment files describe the 2 veins as replacement. At the time of the exploration and development of the mine all base metal mines were replacement. Some of the sulphide samples collected from the dump are banded and suggest a more exhalitive origin. The north vein is explosed in trench east of the main road. The trench has not been cleaned out a number of years. The north vein looks like a vein cutting the host rock but the lichen obscures any visible relationships.
