It will never happen..as has been repeated for years by many who are cognitive thinkers.
And, as I said, the old run down mines have little value to any real mining company anyhow. All it would take would be researching to see how much some well-funded juniors or majors paid for a property. The answer is --not much---and, as I said earlier today, they prefer properties that have had recent development. Both the GC and CM are far from being at the stage where reserves could be discussed, or a feasibility study provided.
Sorry, but it is way past time to take the tax writeoff.
