There is some definitive language in the intro to the BFS
This is from the BFS link that Chappy posted
Copper Fox Metals Inc. (Copper Fox) holds title and a 100% working interest in the
Project consisting of 55,779.56 ha (137,834 ac). Included in this total are the
“Schedule A” mineral tenures originally conveyed to Copper Fox pursuant to the
option agreement dated January 1, 2002 between Teck Resources Limited (Teck)
and Copper Fox (the Teck Option Agreement), which consist of 8,334.34 ha
(20,594 ac). The “Schedule A” mineral tenures are subject to a 3.5% Net Profits
Interest held by Royal Gold, Inc., a 30% carried Net Proceeds Interest held by Liard
Copper Mines Limited (Liard) and, together with the additional mineral tenures
obtained by Copper Fox within the “Area of Interest” provided for in the Teck Option
Agreement, an earn back option held by Teck. With this feasibility study, Copper Fox
will earn Teck’s 78% interest in Liard. Teck’s earn back option to acquire either,
20%, 40% or 75%, of Copper Fox’s interest in the Schaft Creek Property (the
Property) is triggered upon delivery of this feasibility study to Teck. Should Teck
elect to exercise its option for 75%, Teck is required to fund subsequent property
expenditures up to a total of 400% of those incurred by Copper Fox (approximately
$85.3 million on December 31, 2012) and arrange for project financing, including the
Copper Fox portion. For full details of the Teck earn back option, please refer to
