Ann: NMPP Regional Exploration Update, page-8

also to note is their comment on Boda4 where they say ALK will do ground gravity survey over Boda4 and will extend to Boda2/3. Lot of surveys over the last few years.
It only needs one to consistently line-up/correspond to the high grade zones while canceling out most of the lower grade zones and ALK will have something close to a silver bullet.
Or combination of 2 surveys to confirm a target with ~70% hit rate will be massive step in making more discoveries.

At Northparks they have worked out something along these lines (a pattern how to identify targets) and discovered around 24 intrusions of which large number are minable.
