The land and water board has another six weeks to finalize the permits.

Optimized rougher flotation tests recovered 95.3% to 97.7% of the zinc, compared to 80.4% to 91.5% in the first tests.

The Macmillan Pass project is the largest undeveloped zinc and lead resource in the world held by a junior Canadian company.

The smelter halted output on May 28 due to an unplanned outage at the blast furnace.

As the global demand for base metals grows, the mining industry is on the hunt for new deposits that can be developed into operating mines.

The company expects to be able to process 85 million tonnes of mineral per year.

The survey will be flown and processed by CGG Canada Services using its Falcon system on a helicopter platform known as HeliFalcon.

Port Pirie produced 160,000 tonnes of lead metal last year, down 7% from the previous year.

The actual restart date is expected in the first half of 2020.
