The Abitibi Greenstone Belt: One of the World’s Richest

25/7/2020· For investors who like to participate in the mining sector, and junior mining in particular, familiarity with the Abitibi Greenstone Belt in Canada is essential. The Abitibi is the world’s largest mineral-rich greenstone geological belt, hosting many major gold and base metal deposits. It is a 450 km long by 150 km wide geological structure that runs through the Canadian Shield, from west of

Mesothermal and Greenstone Gold Deposits AKA Orogenic

Mesothermal gold deposits form half way up through the rise of the melt from the deep crust to the surface usually at a depth of less than 10 km but greater than 1 km. temperatures at these depths are generally somewhere between 450 degrees and 250 degrees Celsius. The term mesothermal veins is really a sack term, referring simply to the depth formation. It pays little attention to the origin

The Birimian Greenstone Belts of West Africa June 2013

I learned a lot about greenstone belt gold deposits while prospecting them in person, and it was an amazing trip. I heartily recommend Australia to any prospectors who have the money and the desire to visit. Recently I was offered something very different—an unusual opportunity to join a group of people visiting West Africa and the greenstone belt gold deposits there. This area has become

Youanmi and Sandstone: Overlooked plays are back in the

17/5/2020· The Youanmi and Sandstone regions have long been known for their gold prospectivity and production, but until recently they have been largely overlooked compared to the main greenstone belts in Western Australia. Gold was discovered at Sandstone at the end of the 19th Century with the greenstone belt producing over 1.3 million ounces of gold []

The World-Class Abitibi Greenstone Belt of Canada

17/10/2019· Overview. Several of the world’s largest gold and base metal deposits are found in eastern Canada’s Abitibi greenstone belt (AGB). The term world-class can sometimes be overused, but the AGB really earns the title, hosting 11 gold deposits over 100 tonnes, including one of the biggest deposits in the world, the >1000 t gold Hollinger-McIntyre deposits near Timmins, Ontario.

Galane Gold: Exploration & Development

The gold mineralisation occurs in banded iron formation ("BIF") rocks hosted by other meta-sedimentary and meta-volcanic rocks equivalent to the Lady Mary formation of the Tati greenstone belt. The mineralisation is from surface, the BIFs forming a positive topographic feature. We have produced a conceptual mine plan, based on $1,400 gold, which could mine 680,000 tonnes of ore at an average
