THE DRILL SERGEANT: PolarX Limited (ASX: PXX) has identified potential for approx. 600 metres of mineralised strike length at the Zackly East Skarn within the company’s Alaska Range project.
PolarX determined the potential via trenching, mapping and sampling and results from diamond drill holes undertaken in 2018 that intersected thick copper and gold mineralisation commencing from near surface at Zackly East, returning:
55 metres at 2.8 grams per tonne gold and 0.6 per cent copper; and
47m at 3.1g/t gold and 0.6 per cent copper.
These early diamond drill holes discovered the mineralised Zackly East Skarn in 2018, which dips gently to the north and is mineralised over much thicker zones than the previously known subvertical dipping Main Skarn.
The Zackly East Skarn host unit was originally limestone, but was emplaced by way of thrust faulting and now sits in the hanging wall above the thrust fault.
The Main Skarn of the Alaska Range project lies below the thrust fault in the footwall.
The Main Skarn and East Skarn lie within a structural corridor that runs from the Mars porphyry discovery through Zackly and to the northern edge of the Saturn porphyry target and contains many untested magnetic and structural targets that the company considers could have the potential to host multiple additional skarn deposits, as well as larger porphyry copper deposits.
“PolarX intends to pursue the porphyry targets at Mars and Saturn with funding to be provided via an earn‐in joint venture arrangement,” PolarX said in its ASX announcement.
“Discussions have commenced with multiple interested parties.
“The company will continue to fund its own resource expansion drilling at Zackly and Zackly East.”
