(i) Reserves;
(ii) Contingent Resources;
(iii) Prospective Resources; and
(iv) other assets material to the Mineral Company;

Note: Examples of other assets material to a Mineral Company are: a pipeline which is not part of the producing assets facilities, an evacuation pipeline, or a petrochemical plant.

(c) a summary of the fiscal terms under which the licence(s) or permit(s) are held must be stated;
(d) varying discount rates (including the weighted average cost of capital or the minimum acceptable rate of return that applies to the Mineral Company when the evaluation is made) or a fixed discount rate of 10% must be applied;
(e) if the NPVs attributable to Reserves are disclosed, they are presented using a forecast price as a base case or using a constant price as a base case. Under the base case:—

(A) the cost inflation rate;
(B) if applicable, the exchange rate;
(C) the effective date; and
