Our 25% increases $64M US everytime the LT copper increases by $0.25 US.

Let's assume that our value today, after the 2021 Program is completed, becomes $640M US.  Waiting another year for the LT copper price to move from $3.50 US to $3.75 US would only provide a 10% ROI, before capex escalation.

If capex increases 2%-5% per year, it would offset a good chunk of the copper price gain.

Anything below a 15% net gain is not worth the wait/risk in my opinion!
