There is also a poor correlation between holes in the position of the better assay results and so a second programme of core sampling will now be carried out to ensure that no significant gold bearing sections were missed in first pass sampling.\n The discrepancy between the position and tenor of assay results between the two holes could be a result of natural geological variation, which can be significant over short distances in high grade gold deposits, or due to the different drilling methods employed. Battle Mountain's percussion drilling method gives a larger and arguably more representative sample, but percussion drill samples can also be compromised by ground conditions, sample recovery and down-hole contamination issues. Percussion drilling does not deliver the same level of geological information as core holes which is why core drilling was chosen by the Company for this important first hole.\n PYR 9 was originally drilled by Battle Mountain to test a strong gold, silver and multi-element soil geochemical anomaly that remains open to both the north and south. Now that the underlying alterat...
