Here is the note to the las t FS about the NSR (after dilution to -10%)...
"(a) On May 15, 2006, the Company and Spider Resources Inc. ("Spider") agreed to amend and revise their joint venture agreement. The companies agreed to treat each project in their joint venture as a separate joint venture, to enable each company to either increase or decrease its interest in a project based upon their respective strategic objectives. The Company and Spider agreed to have their respective interest established at 50% in all the current projects of the joint venture.
Each party’s interest is diluted by not contributing further to the other party’s exploration program until its interest has reached 33 1/3%. At that level, a party’s interest in a project may be maintained by contribution to subsequent programs, or suffer further dilution. When an interest has been reduced to less than 10%, it will be automatically converted to a 0.5% Net Smelter Royalty ("NSR") in base metals and a 1% NSR in precious metals and diamonds."
