PolarX Limited (ASX: PXX) has commenced RC percussion drilling of the highly promising gold-silver drill target near the head of Star Canyon in the Black Canyon claims within its Humboldt Range Project in Nevada, USA.
A minimum programme of q0 holes for 1,500m is planned, followed by a similar programme at the nearby Fourth of July claims.
Black Canyon is at the northern end of Humboldt Range and is less than three km from the currently operating Florida Canyon Mine, which hosts 5Moz gold.
New Results From Star Canyon
Infill soil sampling and channel sampling was completed at Star Canyon over heavily altered and mineralised volcanic rock outcrops within a very large gold, silver, lead and arsenic in soil geochemical anomaly.
Results of these programmes and location of the planned RC drill collars are presented below.
Infill Soil Sampling Results
The entire Black Canyon claim block was previously sampled on a 200m x 50m grid and has been infilled to a 100m x 25m grid over gold/silver anomalous areas.
• Infill sampling highlights a very large cohesive gold anomaly in the eastern part of the claims, which extends for over 2300m along strike and approximately 900m across strike at >30ppb gold.
• Previous geochemical orientation soil surveys by the Company confirmed that 30ppb gold is considered anomalous and may represent bedrock mineralisation.
• The infill sampling also highlights that the large gold anomaly is associated with highly anomalous levels of silver, lead and arsenic, consistent with observations of mineralised samples in the field.
o Within this large multi-element soil geochemical anomaly, the eastern part of Star Canyon contains a coherent gold in soil anomaly which is situated at the break in slope and which measures 645m long x 500m wide at >50ppb Au, before being concealed under thin soils to the north and south.
Channel Sampling Results
• Channel sampling has been undertaken across extensive outcropping ridges of intensely silicified and oxidised volcanic rocks hosting multiple quartz vein arrays and old gold-silver workings within the Star Canyon gold anomaly
• Highly anomalous gold and silver levels were recorded in six of the eleven channels that were sampled
• The anomalous surface channel sampling results are consistently at or above the cut-off grades at the two proximal large-scale mines, confirming their potential commercial significance prior to drilling
• This area represents the Black Canyon’s best-known target for large tonnage, low to moderate grade gold-silver mineralisation, with drill testing now underway.
Next Steps
A 1,500m (ten hole) programme of RC drilling has commenced in Star Canyon, with a similar program to follow at the Fourth of July claims. This initial drilling is expected to be finished in approximately four weeks.
