Who We Are

Tom MacNeill is founder, president and CEO of 49 North Resources a resource investment and development company headquartered in Saskatchewan. Along with Andrew Davidson and Dean Nawata, 49 North has been directly involved at in several successful junior resource projects from inception through exit or buy out such as Athabasca Potash, Prairie Hunter Oil & Gas and Copper Canyon.

It was 49 North that originally funded and brought Saskatchewan based ground freezing technology to Wingdam, then a private company, and under Len Sinclair’s stewardship, in 2012 successfully recovered 5.4 kilos of placer gold locked under 50 meters of wet overburden beneath Lighting Creek.

Omineca’s partner and mining contractor, HCC Mining and Demolition Inc of Saskatoon, SK has specialized equipment, decades of diversified, innovative mining techniques and experience including over 10 years of alluvial gold mining operations.

Placer Recovery and Hard Rock Gold Exploration

Both of OMM’s Wingdam and Fraser Canyon Projects have two distinct yet related

programs:

• An underground alluvial gold recovery program underway at Wingdam and exploration

for additional potentially gold-bearing paleochannels at Fraser Canyon.

• An exploration program for potential hard-rock lode gold mineralization and/or potential

sources for the placer gold found in the area.
