Superior Lake Resources Ltd. is kicking off a restart study for its Superior Lake zinc-copper-gold-silver project in Ontario after estimating a maiden resource at the project's Winston and Pick Lake mines.

The maiden resource stands at about 2.15 million tonnes at 17.7% zinc, 0.9% copper, 0.4 g/t of gold and 33.5 g/t of silver, according to the July 3 release.

Contained metal is estimated at 378,000 tonnes of zinc, 18,000 tonnes of copper, 27,600 ounces of gold, and 2.3 million ounces of silver. The estimate uses a 3% zinc cutoff.

The project hosts an indicated resource of 2 million tonnes at 17.8% zinc, 0.9% copper, 0.4 g/t of gold and 33.7 g/t of silver, and an inferred resource of 152,000 tonnes at 15.4% zinc, 0.9% copper, 0.4 g/t of gold and 31.2 g/t of silver.

Superior said it will now undertake a planning and implementation strategy to test and understand the true potential of the deposits.

The planned exploration planning will also target extensions and possible hidden mineralization between and adjacent to the Winston and Pick deposits.

The company started project redevelopment activities at the Pick Lake and Winston Lake mines in mid-April with an aim to bring the operations back into production within the next three years.
