That would leave CUU with 25% which nobody would touch if Teck decided to put this project on the backburner for years if they so wish.

They can't put this on the backburner because they have an option to get it back but they don't just get it back because they declare it or show their intention. We're in charge and own it (and Teck doesn't own any) until they've earned their position back from us. That is.. they can't put it on the backburner because it's not theirs until they spend a certain amount REGARDLESS of the 4 year clause. See below:

Option Agreement: Pursuant to a 2002 Option Agreement with Teck, Copper Fox has acquired a 100% working interest in the Schaft Creek Project (subject to a 3.5% net profits interest held by Royal Gold, Inc., a 30% carried interest held by Liard Copper and an earn back option held by Teck Resources Limited ("Teck") Under the terms of the 2002 option agreement with Teck, Copper Fox can earn their 78% interest, or 23.4 % of the deposit, by completing a "positive" Feasibility Study. Pursuant to the Option Agreement, Teck may at any time elect to exercise its earn-back rights, on receipt of a Positive Bankable Feasibility Study, a defined term in the Option Agreement, Teck has 120 days in which to elect to either: i) exercise one of its earn-back options, or ii) retain a 1% net smelter return royalty, or iii) receive shares of Copper Fox to a value of $1,000,000. If Teck elects to exercise its earn-back option pursuant to the Option Agreement, then Teck has the right to elect to acquire either a 20%, a 40% or a 75% working interest in the Schaft Creek Project from Copper Fox by solely funding subsequent expenditures equal to either 100%, 300% or 400% of Copper Fox's prior expenditures pursuant to the Option Agreement. In the event Teck elects to earn-back a 75% working interest in the Schaft Creek Project, Teck will also be responsible for arranging Copper Fox's share of project financing and will recover the project financing funds from Copper Fox's share of metal sales until payout is reached.

Earn BACK option. They don't have anything until they get it back...via spending the money and building the mine. At current, they're spending about 320million in construction before getting anything back, and we have control from what I understand up until that point.
