2.0 Introduction to Mining and Mineral Analysis The overall sequence of activities involved in modern mining is “stages in the life of a mine”. There are mainly five stages in the life cycle of a mine, which follows: 2.1 Mineral Prospecting Prospecting is the first step in any mining activity, which consist of direct search for surface indications of ore mineralization. Mineral prospecting is mainly composed of various activities aimed to search for metallic ores or other valuable minerals, including Coal and other nonmetallic minerals. Since mineral deposits are found either on the surface and or beneath the surface of the earth, therefore direct and indirect techniques are employed, as well as the utilization of Geologic information, to discover the minerals trace and subsequently mineral deposits. Pits, trenches, and shallow drillholes are common activities in conventional prospecting. Deeper drillholes are ordinarily associated with the testing of showed mineralization in the target investigation stage of Exploration. 2.2 Mineral Exploration & Sampling Mineral Exploration aimed to determine as accurately as possible the size and value of mineral deposit, with objective of finding ore with commercially viable concentration of minerals to mine. Various methods and techniques are used to accomplish this task. Some of the methods are similar to the methods used in Prospecting stage, but more refined. Generally the two stages of Prospecting and Exploration are combined, as there is not an exact line separating the two activities. In Exploration stage Geologic and Geophysics information is mainly used to aid in locating the mineral deposits. In addition, more specific and accurate information of the deposit is obtained, by representative and systematic sampling, where subjecting mineral specimens (samples) to Chemical, X-Ray, Spectrographic, or Radiometric analysis. Samples are obtained systematically by Chipping or Trenching outcrops and by Drilling and Excavating below the surface. Additionally, borehole logs may be taken by Geophysics. There are several common drillings methods, Diamond drills provide core samples and Rotary or Percussion drills produce chips or cuttings. Coring is the most useful, but most expensive as well. (a) Area selection is a crucial step in professional mineral exploration activity. Selection of the best, most prospective, area in a mineral field, geological region or terrain will help in making it not only possible to find ore deposits, but to make the process easier, cheaper and quicker. Area selection is based on applying the theories behind ore genesis, the knowledge of known ore occurrences and the method of their formation, to known geological regions via the study of geological maps, to determine potential areas where the particular class of ore deposit being sought may exist. This process applies the disciplines of modeling, structural geology, geochronology, petrology and a host of geophysical and geochemical disciplines to make predictions and draw parallels between the known ore deposits and their physical form and the unknown potential of finding a ‘look alike’ within the area selected.

(b) The target generation phase involves investigations of the geology via mapping, geophysics and conducting geochemical or intensive geophysical testing of the surface and subsurface geology. Sometimes, for instance in areas covered by soil, alluvium and platform cover, drilling may be performed directly as a mechanism for generating targets. (c) Resource evaluation is undertaken to quantify the grade and tonnage of a mineral occurrence. This is achieved primarily by drilling to sample the prospective horizon, lode or strata where the minerals of interest occur. Resource estimation may require pattern drilling on a set grid, and for sulfide minerals, will usually require some form of geophysics such as down-hole probing of drillholes, to geophysically delineate ore body continuity within the ground. The aim of resource evaluation is to expand the known size of the deposit and mineralization. A scooping study is often carried out on the ore deposit during this stage to determine if there may be enough ore at a sufficient grade to warrant extraction; if there is not, further resource evaluation drilling may be necessary. In other cases, several smaller individually uneconomic deposits may be socialized into a ‘mining camp’ and extracted in tandem. Further exploration and testing of anomalies may be required to find or define these other satellite deposits. (d) Reserve definition is undertaken to convert a mineral resource into an ore reserve, which is an economic asset. The process is similar to resource evaluation, except more intensive and technical, aimed at statistically quantifying the grade continuity and mass of ore. Reserve definition also takes into account the milling and extractability characteristics of the ore, and generates bulk samples for metallurgical test work, involving crushability, floatability and other ore recovery guidelines. Reserve definition includes geotechnical assessment and engineering studies of the rocks within and surrounding the deposit to determine the potential instabilities of proposed open pit or underground mining methods. This process may involve drilling diamond core samples to derive structural information on weaknesses within the rock mass such as faults, foliations, joints and shearing. At the end of this process, a feasibility study is published, and the ore deposit may be either deemed uneconomic or economic. (e) Sampling is the process of taking a small representative portion of a larger mass. By analyzing the sample to determine the concentration of metal and minerals it contains, whereby the potential value of a larger mass can be determined. The first samples taken from a mineral showing are called grab samples. Prospectors and geological field crews grab samples from outcrops, road cuts, trenches or river beds. These rocks are selected specifically because they appear to contain a significant amount of metal, so they are not considered representative of the outcrop or road cut from which they come. In the field, grab samples are gathered, their original location is recorded, each rock is labeled and the most promising ones are sent to a lab for metal analysis.

Page 7


If worthwhile or significant amounts of metal and other minerals are present in such grab samples, channel sampling may be warranted. In this sampling technique, bedrock where the sample was taken is exposed as fully as possible, typically by using a backhoe or some such piece of earth-moving equipment. Next, the outcrop is hosed down with water and, if a zone of mineralization is revealed, representative surface samples are taken at regular intervals across the exposed zone. These samples are usually cut with a portable circular saw equipped with a diamond-studded blade, leaving a linear channel across the outcrop. The surface channel is the most desirable type of sample. It is normally cut about ten cm (4 inches) wide and two cm (3/4 inch) deep across the supposed ore zone. The chips of rock removed are carefully collected, marked and bagged for analysis. Chip samples are sometimes taken by the geologist or engineer for a quick approximation of contained value. Random pieces are quickly knocked off the outcrop with a hammer and chisel, with an effort made to take representative amounts. Chip samples cannot be relied on fully, so they generally do not enter final mathematical calculations of possible reserves. It is highly desirable, but not often practical, to space surface channels at regular intervals along the mineralized zone. This prevents one mathematical calculation in the interpretation process. 2.3 Mine Evaluation & Investment Analysis On the completion of the Exploration phase, the mineral deposit data gathered are used to develop a Feasibility–Study, which aim to determine the potential of developing the mineral deposit into a production mine. The outcome of this study shall aid the project management in the decision to abandon or proceed with the project. The Feasibility-Study report is primarily an economic evaluation, however the legal aspects of the project, as well as the technological, geologic, environmental, and sociopolitical considerations shall be covered. The formal feasibility study includes an economic analysis of the rate of return that can be expected from the mine evaluation at a certain production rate. 2.4 Mine Development On the conclusion of the feasibility stage and the final decision of the management to proceed with the project, Mine development work will begin to open a mineral deposit for Exploitation and mining. During this stage, access to the deposit is gained either by stripping the Overburden, to expose the near surface ore for surface mining, or by excavating openings from the surface, to gain access more deeply buried deposit (Overburden is the earth and or rock covering the mineral deposit, which either contain no mineral or so little mineral, which will not be feasible to process). During the development phase enough development is done, before the Exploitation phase, to insure that production once started, can continue without interruption, throughout the life of the mine.

2.5 Mine Exploitation Mine Exploitation is composed of a range of activities aimed in actual recovery (in quantity) of mineral from the deposit. The main emphasis during this stage is on production. The method of mining chosen during the exploitation is based mainly on the ore characteristic and the mineral deposit. However there are other issues, which also influence the mining method, technology required for the exploitation stage, as well as the economics, geologic conditions, and safety issues are among the factors, which influence the decision. Exploitation methods are mainly composed of two general categories: (a) Surface mining methods, which includes Mechanical extraction methods, such as Open-Pit, Open cast, Aqueous extraction methods, such as Placer and Solution mining. (b) Underground mining methods are classified into three groups, including Unsupported (e.g., Room and Pillar mining, Sublevel stopping), Supported (e.g., Cut and Fill stopping, Square set stopping), and Caving (e.g., Long wall, and Block caving). Besides the above traditional mining methods, Novel or Innovative exploitation methods are continually evolving. These novel exploitation methods are applicable to unusual deposits, whereby unusual techniques and technologies are employed.

3.0 Description of Analysis Methods 3.1 Atomic Absorption Spectroscopy (AAS) The technique makes use of absorption spectrometry to assess the concentration of an analyzed in a sample. It relies therefore heavily on Beer-Lambert law. In short, the electrons of the atoms in the atomizer can be promoted to higher orbital for a short amount of time by absorbing a set quantity of energy (i.e. light of a given wavelength). This amount of energy (or wavelength) is specific to a particular electron transition in a particular element, and in general, each wavelength corresponds to only one element. This gives the technique its elemental selectivity.

3.2 Neutron Activation Analysis (NAA) A nuclear process used for determining a certain concentrations of elements in a vast amount of materials. The particular advantage of this technique is that it does not destroy the sample. The sample is introduced into the intense radiation field of a nuclear reactor. The sample is thus bombarded with neutrons, causing the elements to form radioactive isotopes. The radioactive emissions and radioactive decay paths for each elements are well known. Using this information it is possible to study spectra of the emissions of the radioactive sample, and determine the concentrations of the elements within it. Prompt Gamma ray

3.3 X-ray Fluorescence (XRF) The use of emission of characteristic “secondary” (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.

3.4 Inductively Coupled Plasma (ICP) An Inductively Coupled Plasma (ICP) is a type of plasma source in which the energy is supplied by electrical currents which are produced by electromagnetic induction, that is, by time-varying magnetic fields. A high precision technique used to measure combinations of metals to millionth levels of accuracy. Alloys and Platinum Group metals can also analyzed using the ICP technique.

3.5 Aqua Regia Aqua Regia is a highly corrosive, fuming yellow or red solution. The mixture is formed by freshly mixing concentrated nitric acid and concentrated hydrochloric acid, usually in a volumetric ratio of 1:3 respectively. It was so named because it can dissolve the so-called royal, or noble metals gold and platinum, although tantalum, iridium, osmium, titanium and a few other metals are able to withstand it.

3.6 Fire Assay / Cupellation The most elaborately accurate, but totally destructive, precious metal assay is fire-assay. (It may also be called by the critical cupellation step that separates precious metal from lead.) If performed on bullion (high purity precious metal alloy) to international standards, the method can be accurate on gold metal to one part in 10,000. If performed on ore materials using fusion followed by cupellation separation, detection may be in parts per billion, the method is the accepted standard applied for valuing gold ore as well as gold and silver bullion at major refineries and gold mining companies.
