I was thinking the opposite... the 2km long 'Targets' line counld represent where they have already been grab and channel sampling. As it appears from the mag map this quartz vein may be more exposed/closer to the surface. Therefore, would be 'targets' for upcoming drilling. The 'identified' veins are ones that have been somewhat stripped and 'identified' but will be part of follow-up exploration.
(FYI... not that this means anything but there are ~45 yellow dashed lines within that 2km section :D... I know I have too much time on my hands LOL)
Could be either. Interesting question though.
