Gold Occurrences in Labrador
and Labrador are one Newfoundland their geological histories are so different that we have decided to treat them as separate entities. Throughout most of geological time province of Canada Labrador has been part of the Canadian Shield with some of its far north disturbed by a fairly recent orogeny that raised the . The Torngats are in Torngat Mountains , Quebec Labrador and a small pert is in . Geologically they are considered the Artic Cordillera with the highest mountain being Nunavut at 1,652 m (5,420 ft.) Geographically Mt. Caubvick Labrador contains some of the wildest land on the East Coast of North America to the point it even lacks a trans-Labrador highway. It is also little explored even though it is known to contain gold.
There are many geochemical anomalies of gold phoned him the Archean Nain Province where it is associated with strong iron carbonate alteration of the
greenstone belt and in quartz base metal veins at the Aucoin showing. The superior province also contains several areas that show minor gold mineralization where the northern occurrences are associated with metamorphosed iron deposits in the southern ones with pyrite-pyrrhotote-arsenopyrite veining in mafic and metasedimentary gneisses. Gold is also found in the eastern Makkovik province where it occurs as small being hosted the positives in quartz. These are found in felsic volcanic rocks at Poiniadluk Point. In the southeastern Florence Lake gold is found that the VBE-2 prospect where it is located in the Tasuyak metasedimentary gneiss that contained up to 5.5 grams per tone located in sulfide-graphite rich layers. Churchill Province
Gold is often found associated with greenstone belts that extend across the Archean all the way from Wawa
to past Chibougamau Ontario . This is such wild country that it has never been thoroughly explored for gold and it is likely that the Abitibi Greenstone Belt extends eastwards into Quebec Labrador.
During the mid-1800s my great-grandfather prospected for gold in
Labrador where he found enough to make my great-grandmother's wedding ring. Some prospecting was done as early as 1870.
