In the announcement, it was mentioned that they are drill testing each of the 9 targets from west to east, and upon completion (which is not far away), they will commence a resource drilling program (I guess that's when they will test extension along strike & depth?). 

Iron Duke will be very interesting to watch, sitting right above the purple shade in the SAM survey with over 600m of visual strike length. Definitely a high conductor zone, the question is at what depth?

Newcrest recently completed 6x 1000m DD, and is currently drilling more follow-up holes. AMG is being a little cheeky here with their intention to drill 2x 800m DD, perhaps as a proof & statement to Newcrest that their (assumed) mineralisation extends into AMG's tenement.
