Mining and Satellite Imagery. Satellite imagery and aerial photography have proven to be important tools in support of mineral exploration projects. They can be used in a variety of ways. Firstly they provide geologists and field crews the location of tracks, roads, fences and inhabited areas.

Established in Canada in 1960 by mining engineer A.C.A. (Peter) Howe, ACA Howe International have a long history of providing geological and mining services to exploration and mining companies, financial institutions and private investors. The group has contributed to significant mineral discoveries and worked on many successful projects worldwide.
The CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (MRMR Best Practice Guidelines) were prepared by the Canadian Institute of Mining, Metallurgy and Petroleum's (CIM) Mineral Resources and Mineral Reserves Committee (CIM MRMR Committee) to update an earlier version that was accepted by CIM Council on November 23, 2003 (CIM, 2003).
A Mineral Reserve includes diluting materials and allowances for losses that may occur when the material is mined. Mineral Reserves are sub-divided in order of increasing confidence into Probable Mineral Reserves and Proven Mineral Reserves. Mineral Reserves are those parts of Mineral Resources which, after the application of all mining factors
Reserve Mining Company It was exciting to be part of a bold new idea to make blast furnace feed from low grade taconite in the 50's and 60's. But suddenly in the 70's everything changed. Outsiders who previously thought of us as the good guys, now called us bad guys.
Jan 16, 2017· The mining industry is a fascinating space not only for the fact that almost everything around us comes from mining but also because of the possibility of striking gold with penny stocks that

Mineral resource classification is the classification of mineral resources based on an increasing level of geological knowledge and confidence. In an effort to achieve a standard set the classifications, representative bodies from Australia, Canada, South Africa, the USA and the UK reached a provisional agreement in 1997 on the definitions of each of the various mineral classifications.
Mineral Resource Estimation. Mining and Exploration Data Management We find, delineate, and estimate the size and quality of mineral deposits using tools that minimize risks, cut costs, and reduce time frames. We map open pit and underground mines and improve grade control, ore reserve modelling, mine plans, and near mine drill targeting.

Dec 04, 2018· Consolidation of the Mining Property Disclosure Requirements and Compliance Date. The amendments consolidate the Commission’s mining property disclosure requirements by relocating them to a new subpart of Regulation S-K (Subpart 1300). Registrants must comply with the new rules for the first fiscal year beginning on or after January 1, 2021.
Jul 21, 2017· How Does Asteroid Mining Work? To put it mildly, asteroid mining is going to be complicated.Yet despite the myriad complexities, a handful of private companies—including Deep Space Industries, Kepler Energy & Space Engineering and Planetary Resources—have started to draw up plans to get into the asteroid mining game. Regardless of who gets their hands on an asteroid first,
Resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods (see below) used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
Estimation of ore reserve is essentially one of the most important platforms upon which a successful mining op-eration is planned and designed. Reserve estimation is a statistical problem and involves determination of the value (or quantity) of the ore in unsampled areas from a set of sample data (usually drill-hole samples) X1, X2, X3, .
The AusIMM’s Monograph 27, Cost Estimation Handbook (second edition 2012) provides a set of standards that may become more widely used. The level of engineering that has been attained in a feasibility study is usually well short of that required for construction, so a further period of detailed engineering design follows after the project has
This guide to mining valuation will teach you all you need to know to value an asset! The best way to value a mining asset or company is to build a discounted cash flow (DCF) model that takes into account a mining plan produced in a technical report (like a Feasibility Study). Without such a study available, one has to resort to more crude metrics.
Oct 17, 2019· Mineral Reserves. The difference between a resource and reserve boils down one thing: a feasibility study. At the very least a preliminary, or “pre-feasibility” study must be completed which takes into account the “Modifying” non-geological factors. These include technical factors include mining, processing, metallurgy.
Proven and Probable mineral reserves and Measured and Indicated mineral resources are commonly misused terms. The exact definitions can be hard to find but here they are all in one place, referenced from NI 43-101 and the JORC code.
Global Mining Leader Projects KPMG in Australia Few mining companies possess either the engineering strength or the will to build a mine completely independently. The ‘engineer, procure, construct’ (EPC) model is an increasingly popular approach to oil, gas and infrastructure development, with full responsibility
Before you can calculate the potential mineral deposit value, you first need to gather some specific data regarding the ore body and the individual drill results.. This required data can be found in the mining company’s press releases in which they announce their drill results.Make sure that this data is announced according to the guidelines of National Instrument 43-101 (i.e. approved by a
Oct 31, 2018· Under the final rules, a registrant with material mining operations must disclose specified information in its Securities Act and Exchange Act filings concerning its mineral resources, in addition to its mineral reserves. Current Commission rules and guidance permit the disclosure of non-reserve estimates only in limited circumstances.
