most tenements only get picked up if useful to the company. This is likely to be more ground around something they have with aeromags supporting the strike beneath. They are not expensive to buy, they just cost a bit to manage as you have to work them. If its any good they can raise on the back of it and drill the f!@#$% out of it and hopefully find some more of whatever they think is there. Given they just found some copper it is likely to be more copper. They already have enough cobalt.
