A metallurgical study is not needed since the mine was in production so they know what their gold recovery percentage will be. They have to rerun the economics anyways so some level of feasibilty study is required. That's not a big concern since the price of gold has gone up since the mine closure and I doubt operating costs have climbed as much. My involvement with mining was in exploration, not the business side, so these are educated guesses. I haven't read the fine print in the option deal but will eventually if it's posted on Sedar. Some deals require a specific amount of addtional resource must be found in order to earn the option. So I would be looking for whatever conditions are attached to the option.
