Earlier this week the company received more encouraging drill results from its Alaska Range Project in Alaska.
There were 9.6 metres of copper sulphides observed in core from a hole 50 metres east of the JORC-compliant resource at the Zackly copper-gold deposit.
In addition, drilling has hit visible copper oxides 850 metres along strike from the resource, visible gold 300 metres along strike, and visible copper and gold 100 metres below the resource.
Potential resource expansion
The results support a resource expansion for the deposit with Zackly also remaining open at depth and along strike in both directions.
Alaska Range also hosts the Caribou Dome deposit and the project boasts a combined resource of 127,000 tonnes of copper, 213,000 ounces of gold and 1.5 million ounces of silver.
Earlier this year PolarX completed a share placement to raise about $2.52 million from existing major shareholders and new investors via the issue of shares at 10.5 cents each.
