(6)
(c)
(2) Any disclosure of an exploration target must appear in a separate section of the Commission filing or technical report summary that is clearly captioned as a discussion of an exploration target. That section must include a clear and prominent statement that:
(3) Any disclosure of an exploration target must also include:
(d)
(1) A registrant's disclosure of mineral resources under this subpart must be based upon a qualified person's initial assessment, as defined in § 229.1300, which includes and supports the qualified person's determination of mineral resources.
(i) When determining the existence of a mineral resource, a qualified person must:
(iii)
(B) For inferred mineral resources, a qualified person:
(1) Must have a reasonable expectation that the majority of inferred mineral resources could be upgraded to indicated or measured mineral resources with continued exploration; and
(2) Should be able to defend the basis of this expectation before his or her peers.
(3) The qualified person must provide a qualitative assessment of all relevant technical and economic factors likely to influence the prospect of economic extraction to establish economic potential and justify why he or she believes that all issues can be resolved with further exploration and analysis. As provided by Table 1 to paragraph (d) of this section, those factors include, but are not limited to, to the extent material:
(4)
(ii) If providing an economic analysis in the initial assessment, a qualified person may include inferred mineral resources in the economic analysis, provided that the qualified person:
(C) Discloses, with equal prominence, the results of the economic analysis excluding inferred mineral resources in addition to the results that include inferred mineral resources.

Assess requirements for baseline studies. Assume post-mining land uses. Assume tailings disposal, reclamation, and mitigation plans | Identification and detailed analysis of environmental compliance and permitting requirements. Detailed baseline studies with preliminary impact assessment (internal). Detailed tailings disposal, reclamation, and mitigation plans | Identification and detailed analysis of environmental compliance and permitting requirements finalized. Completed baseline studies with final impact assessment (internal). Tailings disposal, reclamation, and mitigation plans finalized. |
| Other relevant factors 2 | Appropriate assessments of other reasonably assumed technical and economic factors necessary to demonstrate reasonable prospects for economic extraction | Reasonable assumptions, based on appropriate testing, on the modifying factors sufficient to demonstrate that extraction is economically viable | Detailed assessments of modifying factors necessary to demonstrate that extraction is economically viable. |
| Capital costs | Optional.3 If included:Accuracy: ±50%.Contingency: ≤25%. | Accuracy: ±25%Contingency: ≤15%. | Accuracy: ±15%.Contingency: ≤10%. |
| Operating costs | Optional.3 If included:Accuracy: ±50%.Contingency: ≤25%. | Accuracy: ±25%Contingency: ≤15%. | Accuracy: ±15%.Contingency: ≤10%. |
| Economic analysis 4 | Optional. If included: Taxes and revenues are assumed. Discounted cash flow analysis based on assumed production rates and revenues from available measured and indicated mineral resources | Taxes described in detail; revenues are estimated based on at least a preliminary market study; economic viability assessed by detailed discounted cash flow analysis | Taxes described in detail; revenues are estimated based on at least a final market study or possible letters of intent to purchase; economic viability assessed by detailed discounted cash flow analysis. |
| 1 When applied in an initial assessment, these factors pertain to the relevant technical and economic factors likely to influence the prospect of economic extraction. When applied in a preliminary or final feasibility study, these factors pertain to the modifying factors, as defined in this subpart. | |||
| 2 The relevant technical and economic factors to be applied in an initial assessment, and the modifying factors to be applied in a pre-feasibility or final feasibility study, include, but are not limited to, the factors listed in this table. The number, type, and specific characteristics of the applicable factors will be a function of and depend upon the particular mineral, mine, property, or project. | |||
| 3 Initial assessment, as defined in this subpart, does not require a cash flow analysis or operating and capital cost estimates. The qualified person may include a cash flow analysis at his or her discretion. | |||
| 4 An initial assessment does not require capital and operating cost estimates or economic analysis, although it requires unit cost assumptions based on an assumption that the resource will be exploited with surface or underground mining methods. An economic analysis, if included, may be based only on measured and indicated mineral resources, or also may include inferred resources if additional conditions are met. |
(e)
(2) When determining mineral reserves, a qualified person must subdivide mineral reserves, in order of increasing confidence, into probable mineral reserves and proven mineral reserves, as defined in § 229.1300. The determination of probable or proven mineral reserves must be based on a qualified person's application of the modifying factors to indicated or measured mineral resources, which results in the qualified person's determination that part of the indicated or measured mineral resource is economically mineable.
(3) The pre-feasibility study or feasibility study, which supports the qualified person's determination of mineral reserves, must demonstrate that, at the time of reporting, extraction of the mineral reserve is economically viable under reasonable investment and market assumptions. The study must establish a life of mine plan that is technically achievable and economically viable, which will be the basis of determining the mineral reserve.
(7) Factors to be considered in a pre-feasibility study are typically the same as those required for a final feasibility study, but considered at a lower level of detail or at an earlier stage of development. The list of factors is not exclusive. For example, as provided in Table 1 to paragraph (d) of this section, a pre-feasibility study must define, analyze or otherwise address in detail, to the extent material:
(10) A feasibility study must contain the application and description of all relevant modifying factors in a more detailed form and with more certainty than a pre-feasibility study. The list of factors is not exclusive. For example, as provided in Table 1 to paragraph (d) of this section, a feasibility study must define, analyze, or otherwise address in detail, to the extent material:
