RE:RE:sabinaseanyboy is right, It's all or nothing, at least for the foreseeable future.
I don't see Hackett being spun off, even if it was possible, which it probably isn't. I suppose they could borrow against it, but if GX decides to put the project on ice (of which there's a lot up there) then your collateral goes out the window, so that may not be an option either.
I'm betting that Hackett moves forward, the royalty cash starts flowing and Back River moves from a possible to a probable mine. I have to admit it's a lottery ticket under current conditions, but the shares are so sold off that if things fall in line for Sabina, the payoff will be extraordinary. Just don't bet the rent money!
