Figure 5 and Figure 6 provide a two-page checklist of the technical information that describes a typical operating mine. Likewise, Figure 7 provides the checklist for Oil and Gas operations. Unfortunately, the information obtainable by the general public can be very limited. To find useful information, many resources must be searched through.

 
In Canada, an NI 43-101 could have been prepared which provides the anticipated answers to the checklist but this document is prepared in advance of an operating mine. The CIM (2013) offers  best practice guidelines    on the detail of engineering required for a preliminary feasibility study associated with preparing an NI 43101 study. In Canada, groups of professionals will work together to describe the meaning of certain types of legislation and will produce best practice guidelines.

As per the previous paragraph, this document is interested in the producing stage when actually details are described based on how the mines operated. To get to this stage, it is assumed that an orebody was found and went through the following stages of evaluation:

• Conceptual study
• Pre-feasibility study
• Feasibility study

At each level of study, the detail and cost estimates would have increased in confidence. Pincock Allen & Holt

(2018) provide their own checklist based on these different levels of studies required in advance of a mine ever
getting to the operational stage.
