Maybe?

"Well into the 2030's" was the quote in the article.

Assuming production starts around 2018, and adding the expected 14-year life span, that would mean the mine would be viable until around 2032. Add a few years for decommissioning and reclamation, and the number seems to be consistent with earlier estimates.

However, I do agree with the sentiment that there is a definite possibility for a much longer life, pending further exploration.
