Just to add to your post Yeatesy.

The Citronen Project is a relatively simple predominantly underground room and pillar mining operation that concentrates the
ore through industry-proven Dense Media Separation (DMS) and Flotation techniques to produce saleable separate zinc and
lead concentrates to the world markets.
Table A above demonstrates the sensitivity of the project’s economics at a range of zinc prices. Every US$100/t
increase/decrease in the zinc price adds or reduces by approximately US$100M to the pre-tax NPV and every reduction reduces
the pre-tax NPV. The financial model applies annual indexing to all cost and prices using a CPI rate of 2.5%.
Plus remember it has been stated that there is a mine life of yes 100 years.
