Further to my last, the point is listed as a bird sanctuary. You have an additional complication of flying a drone amongst the flocks of passing whatevers.

A search for "Consecon Air Weapons range" came up with many hits as a well known UXO site. I didn't look too deeply, but if it has been demined or surveyed, whoever had the contract would have reported all their findings to the Crown. I'd suggest trawling through the searches to find which company had the contracts, when, and then spend $5 for an Access to Information request with the specific questions of 'what big stuff did they find?' and 'where is it?'. If part of the survey included magnetometer data, "tanks" would show up like the balls on a dog. I know DND's UXO program points outwardly so requests will probably be considered generously not like you're trying to find the PM's security detail budgets or anything politically sensitive.
