Since some of the shareholders at AZL are confused about this, it is easy to get permission from BLM for drilling on public land that affects less than 5 acres (2 hectares). It is assumed that there is no environmental impact, so the company just has to post a bond (usually, just an advance payment) to cover the cost of filling the hole. The area measured is only what immediately surrounds the drill site, and any access roads that do not already exist. AZL did this with its Phase 1 and Phase 2, but now has been waiting since 2019 for permission to drill 145 holes and dig a mass sample about the size of a swimming pool. Their problem is that the claim is adjacent to land owned or leased by Native Americans, who have special status in some situations. I live a couple hours from Wickenburg, and from the pegmatite claim to the east of there being explored by Bradda Head. I don't know of any Native American interference that may be anticipated in either location.
