These have returned gold grades which are significantly higher than those reported in initial assays on the same samples.
The assays for the first five holes returned high‐grade results of up to 3.9% copper and 3.7 g/t gold.
Average grade of 2.7 g/t gold is much higher
Historical reports and PolarX’s observations indicate that substantial amounts of coarse gold may be present at Zackly.
This led PolarX to resubmit 35 drill core samples for assay using a more appropriate screen fire assay technique.
This is generally accepted as more accurate in the circumstances.
The screen fire assays returned an average grade of 2.7 g/t gold, and the highest composite assay was 26.6 g/t gold over 1 metre.
In comparison, the initial assays on the same 35 drill core samples conducted in November and December contained an average grade of 1.97 g/t gold.
Results reflect nugget in nature of gold
In almost all cases, the grade of gold in the coarser fractions is significantly higher than the average grade of the sample, reflecting the nuggety nature of gold in the samples.
The remaining 100 core samples have now been submitted for screen fire assay and all future drill samples from Zackly will be assayed using this method.
Screen fire assays for copper are also expected soon.
These results will be used to calculate the maiden JORC resource estimate for Zackly, it is on track for completion in the March quarter.
