PolarX Delivers Copper-Rich Massive Sulphides in Alaska

PolarX Ltd (ASX:PXX) has intersected 8.3-metre and 12.65-metre-thick zones of copper-bearing massive sulphides at its Caribou Dome Copper Project in Alaska.

Notably, these intersections are beneath hole CD21-001 which returned these encouraging intersections in 2021:

  • 19.1 metres at 7.0 % copper + 11.2 g/t silver; and
  • 9.8 metres at 6.8 % copper + 7.8 g/t silver

So far this season, PolarX has drilled three holes, with all intersecting in mineralisation.

Looking ahead, drilling aims to extend known depth and continuity in this high-grade zone to assist with future underground mine planning.

At the indices, the company’s shares have jumped 18% in the last five days to A$0.013.

About Caribou dome

Caribou Dome is part of PolarX’s Alaska Range Project, which also includes Zackly.

The project is situated about 250 kilometres northeast of Anchorage in Alaska, USA.

As far as accesibility goes, the Denali Highway passes within 20 kilometres of the project.

From there, a purpose-built road provides direct access to the historic underground development at the project.

Caribou Resource

Caribou Dome’s mineral resource was updated in June 2023 to 7.2 million tonnes at 3.1% copper and 6.5 g/t silver.

Notably, the ore body consists of nine deformed lenses of volcanic sediment-hosted fine-grained massive sulphides comprising chalcopyrite and pyrite.

At the field, copper mineralisation has been delineated over approximately 700 metres of the strike and is open below the current 300 metres of resource depth.
