Making sense of the geology of
requires that you also consider that of Minnesota to the North bordering Ontario . Looking at the western end of the Minnesota Abitibi Gold Province located in from the air you see a series of fault lines can be distinguished that from the air that appear to dive under Wawa, Ontario Lake Superior.

The question to be answered is the Vermilion Greenstone Belt that lies to the east of
a western extension of the Lake Vermilion . The Vermilion Greenstone Belt is within the age range of the Abitibi at about 2.7 billion years old. Abitibi Province
Starting in the early 1990s a drilling program was undertaken that suggests that this may be the case. In the past twenty years finding gold in
has drastically changed not only by the findings in the Vermilion Greenstone Belt, but also by the findings associated with the Duluth Gabbro in the Ely district of the Arrowhead of Minnesota. There have been millions of ounces of gold that are associated with the volcanogenic massive sulfides that have been discovered there by Duluth Metals and other mining companies. Minnesota
Prospecting for gold in
goes back to the 19th century when some of the 49ers returned from the California Goldrush. It was some of the early gold prospectors that discovered the Minnesota Mesabi Range while searching for gold.

Like all the other Midwestern States the glaciers have brought down gold from the gold regions of
and Manitoba . Placer Gold is found throughout the state with the best prospecting is in the rivers and streams. Another place where placer gold may be found is along the shores of Ontario Lake Superior. There is an active gold prospecting community located in . This is not counting the lode gold deposits.
