PolarX Limited (ASX: PXX) has hit further wide, locally high-grade intersections of gold and copper at the Zackly East prospect within its Alaska Range Project.
One of the latest holes has returned an assay of 11.2m @ 2.45g/t Au + 1.1% Cu from 52.6m depth.
Zackly East, discovered by PolarX in 2018, sits immediately adjacent to the Zackly Main skarn deposit, where the JORC Inferred Resource currently stands at 213,000oz of gold, 41,000t of copper and 1.5Moz silver.
Managing Director Dr Frazer Tabeart said Zackly East was continuing to grow to the east and remained open in all directions.
These latest results prove that thick zones of near-surface mineralisation continue further to the east, showing locally high-grade zones within a very broad mineralised envelope,” Dr Tabeart said.
“Our most recent drilling has been to the east and north of these results. This again revealed strong skarn alteration in structures associated with very strong magnetic gradients. The high-grade mineralisation at the Zackly Main skarn is also associated with a similar magnetic gradient so further growth in mineralised strike is expected on receiving those assays.
“At least 2km of these newly identified structures remain untested to the north and east of current drilling these are now high priority drilling targets.
“We have also observed features in the new magnetic data consistent with a nearby porphyry target, which also remains untested.”
PolarX is undertaking core drilling at Zackly East using two drill rigs. 23 holes for 3,130m of core have been drilled and logged to date, with skarn alteration observed in most holes.
Copper mineralisation was seen in the majority of holes which intersected skarn alteration.
