Commodity prices change, technology advances, supply and demand fluctuate so there's 101 reasons why companies let go and move on from leases. For example i have an exploration company sitting on what was a worthless deposit for the last 25 years only to find out they didn't test the drill cores for lithium and other elements back then. Considering we paid nothing for it and are getting all the data from as you said 10s of millions of dollars of drilling someone else paid for id say its a bargain and with new technology, increasing price and demand for higher grade ore and a star studded management and consultancy team what's not to like.
