In my opinion the single most important economic variable in a study is how the block model was constructed. More projects are undone by a bad model than by any other factor. Check out Rubicon for a recent example. Therefore, it is critical for an investor to understand how the model was constructed…among other things.
Another factor most people tend to overlook is that models are not deterministic. In the end, the model is simply a model of reality that can be very good or very bad. Further, investors can not verify the competency of the QP so there is a lot of trust in the system. This study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction is justified.
Probable Mineral Reserve The term "Probable Mineral Reserve" refers to the economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource demonstrated by at least a preliminary feasibility study.
Mineral Resource The term "Mineral Resource" refers to a concentration or occurrence of diamonds, natural solid inorganic material, or natural solid fossilized organic material including base and precious metals, coal, rare earth elements and industrial minerals in or on the earth's crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction.
The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge.
Measured Mineral Resource The term "Measured Mineral Resource" refers to that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit.
The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity. Indicated Mineral Resource The term "Indicated Mineral Resource" refers to that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit.
Measured, Indicated, and Inferred are classifications of Resources only, and are also indicators of confidence levels. Measured being the most confident, Inferred being the least.
These categories are not specifically defined and are somewhat left up to the independent qualified person estimating the resource to decide. Factor contributing to resource confidence; -drill hole spacing -geological complexity of the ore body -source of data some times historic data is used to estimate resources and even if there is tight drill spacing, if the qualified person did not personally collect the data, they will likely not put full confidence in it I hoped that helped restate some of the correct info above, and correct some of the misinformation.
As for some Statement items to note; -Plant, Property, and Equipment Assets should be taken with a grain of salt. Right now the I think the best buys are Gold and Silver miners in production.
There is a lot of new work going on this summer and there could be some interesting discoveries. My opinions only, I will not be responsible for any investment losses. MLA I can sort of understand what you are saying, but you cannot use the words proven and probable to describe what you personally consider to be proven and probable when they have legal definitions as outlined by exchange commissions. We present information about mineralization, mineral reserves and resources as required by National Instrument — Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators NI , in accordance with applicable Canadian securities laws.
Note that mineral resources: do not include amounts that have been identified as mineral reserves do not have a demonstrated economic viability numbers may not add due to rounding.
Measured and indicated mineral resources can be estimated with sufficient confidence to allow the appropriate application of technical, economic, marketing, legal, environmental, social and governmental factors to support evaluation of the economic viability of the deposit.
We do not have enough confidence to evaluate their economic viability in a meaningful way. You should not assume that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource, but it is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration. The change was primarily the result of: production at Cigar Lake and Inkai, which removed 8.
They are, however, imprecise by nature, may change over time, and include many variables and assumptions, including: geological interpretation extraction plans commodity prices and currency exchange rates recovery rates operating and capital costs There is no assurance that the indicated levels of uranium will be produced, and we may have to re-estimate our mineral reserves based on actual production experience.
