PolarX Ltd (ASX:PXX) has fielded “extensive” gold and silver assay results from a recent channel traverse sample program at the Golden Staircase prospect near Star Canyon prospect in the Humboldt Ranges of Nevada, USA.
The new discovery sits at one end of a 2.8-kilometre-long soil anomaly.
Recent drilling by PolarX at Star Canyon prospect at the other end of the anomaly – returning assays of up to 9.1 metres at 124.36 g/t gold and 48.6 g/t silver – indicates that the company is looking at a much larger mineralised Carlin-style host system.
Channel sample highlights
Assay results from channel samples of outcropping mineralised veins at Golden Staircase returned wide gold and silver intervals including high-grade zones:
- 51 metres at 1.24 g/t gold and 8.3 g/t silver including 3 metres at 9.62 g/t gold and 60.75g/t silver; and
- 18 metres at 0.71 g/t gold and 5.82 g/t silver including 7.5 metres at 1.05 g/t gold.
The traverses are linked and combine to form a 69-metre-long mineralised surface interval, which overlooks and compares favourably to grades mined at the neighbouring 5-million-ounce Florida Canyon Gold Mine.
Assay intervals AA’ and BB’ actually link as they commence from the same anchor point, combining to reveal a continuous 69-metre-long mineralised interval.
Continuous sampling
The company sampled three continuous saw-cut channel traverses, with the traverses ranging from 120 metres to 200 metres in length.
A composited sample was taken along each 1.5-metre interval in a similar continuous manner to drill-core, effectively replicating a surface drill hole albeit over weathered outcrop.
The company tested the Golden Staircase target due to its coincidence with strongly anomalous gold-in-soil sampling results, previous gold-rich rock-chip samples of up to 4.5 g/t gold and 12.1 g/t silver, an association with intense vein swarms exposed in rocky rhyolite outcrops and the target’s close proximity to trail road access.
Bonanza assay at Star Canyon
The Golden Staircase prospect sits at one end of a 2.8-kilometre-long soil anomaly, with the Star Canyon prospect sitting at the other end.
Recent drilling by PolarX at Star Canyon returned a bonanza assay of 9.1 metres at 124.36 g/t gold and 48.6 g/t silver within a potentially bulk mineable Carlin-style host system.
Given the strength of the results at Star Canyon and Golden Staircase, the company now plans to undertake additional channel sampling and drilling along the remainder of the 2.8-kilometre gold-in-soil anomaly.
Channel-cut traverses are also underway at the nearby Ridgeline Target (NYSE:TGT).
