Marquee Resources (ASX:MQR) is exploring its Werner Lake cobalt-sulphide project in the province of Ontario, Canada. Discovered during the 1920s, the project became a small but high-grade mining operation in the 1940s.

Superior Lake Resources (ASX:SUP) has announced a maiden JORC resource for its Superior Lake Zinc Project in Ontario, Canada that ranks it as one of the highest-grade zinc projects in the world.

Castillo Copper Limited (ASX:CCZ) is exploring the high grade Cangai copper project in New South Wales. The project was mined more than 100 years ago, which saw exceptionally high-grade copper (13% Cu) mined, as well as silver and gold credits.

Superior Lake Resources (ASX:SUP) recently acquired the Superior Lake zinc project in Canada. It was the country's highest-grade zinc operation (3.5 Mt at 14% Zn, 1% Cu) for a decade before closing in 1998 as a result of ongoing low zinc prices. Any exploration work since has been limited, due to the continued low zinc price and the project's fragmented ownership.
