Ann: Exploration Underway at Andover Nickel Project, page-116

"Drilling at Andover by the Creasy Group in 2018 intersected semi-massive, stringer and disseminated
nickel and copper sulphide mineralisation."

I suppose "semi-massive" makes you both half right.

As for heritage sites on the leases I'm with @Blythefan. Whether the leases have been disturbed by previous activities or not, heritage surveys will not have been completed over the entirety of the leases. Heritage surveys are done on an as-needs basis over areas to be disturbed by exploration activities. A request for a heritage survey won't see the survey completed in a week, more likely 1-2 months or more in the wet season.
