Exploration And Development

The framework for mineral exploration and development agreements is not always similar to the pattern developed for similar undertakings in the petroleum industry. This paper describes the basic formats for option agreements and to the extent that there is any uniformity joint venture associations that are commonly used in the mining industry. The role and the components of project financing in mine development are also briefly reviewed.

Nearly all of the well logging devices currently used in the petroleum industry have found some limited application in metallic mineral exploration and mining. However, due to differing problems, the emphasis in the mineral industries has been on those devices regarded as “exotic” or “specialty” by the petroleum industry. These include devices to measure or determine induced polarization, magnetic susceptibility, and, hopefully, nuclear activation and the use of spectral analysis. Problems which the mining industry believes are solvable with well logging methods include bulk assay and recognition of minerals adjacent to and retired from a borehole, delineation of joint and fracture systems, leaching problems which involve porosity, permeability and groundwater movement, bank stability in open pit mines, roof and pillar loading in shaft mines, grindability, and penetration rates in drilling. Devices currently offered by the well logging industry which may be useful for these problems include those capable of measuring electrical properties, natural and induced nuclear radiation, seismic velocities of both compressional and shear modes, temperature, mechanical features of a borehole such as diameter and rugosity, and borehole photography either direct or by television.

Geology of Greenland Survey Bulletin, 183, 39-45. https://doi.org/10.34194/ggub.v183.5203 _______________ The Upernavik 98 project is a one-year project aimed at the acquisition of information on mineral occurrences and potential in North-West Greenland between Upernavik and Kap Seddon, i.e. from 72°30′ to 75°30′N (Fig. 1A). A similar project, Karrat 97, was carried out in 1997 in the Uummannaq region 70°30′–72°30′N (Steenfelt et al. 1998a). Both are joint projects between the Geological Survey of Denmark and Greenland (GEUS) and the Bureau of Minerals and Petroleum (BMP), Government of Greenland, and wholly funded by the latter. The main purpose of the projects is to attract the interest of the mining industry. The field work comprised systematic drainage sampling, reconnaissance mineral exploration and spectroradiometric measurements of rock surfaces.

Geology of Greenland Survey Bulletin, 191, 133-143. https://doi.org/10.34194/ggub.v191.5141 _______________ Project Qaanaaq 2001, involving one season’s field work, was set up to investigate the mineral occurrences and potential of North-West Greenland between Olrik Fjord and Kap Alexander (77°10´N – 78°10´N; Fig. 1). Organised by the Geological Survey of Denmark and Greenland (GEUS) and the Bureau of Minerals and Petroleum (BMP), Government of Greenland, the project is mainly funded by the latter and has the overall goal of attracting the interest of the mining industry to the region. The investigated region – herein referred to as the Qaanaaq region – comprises 4300 km2 of ice-free land centred on Qaanaaq, the administrative capital of Qaanaap (Thule) municipality. Much of the region is characterised by a 500–800 m high plateau capped by local ice caps and intersected by fjords and glaciers. High dissected terrain occurs in Northumberland Ø and in the hinterland of Prudhoe Land where nunataks are common along the margin of the Inland Ice.

In the following article, Mr. Mackay discusses the acquisition and develop ment of mineral property under the provisions of the Mineral Act of British Columbia. The writer reviews three main types of agreements (and the more important terms of the various agreements) used for the acquisition of an "interest" in mineral claim. Financing is requisite of any exploration and development activity, and the author examines various sources of funds available for financing in the mining industry, concentrating on the most common method, incorporating company to take over the development of the mining property, with particular emphasis on the various procedural steps which must be followed before public offering can be made. Finally, Mr. Mackay briefly examines the problem of placing mineral property into commercial production.

Horizontal wells are used in some geological settings in the petroleum industry to produce methane from coal seams. Horizontal directional drilling is used in the mining industry to enhance the effectiveness of coal degasification procedures and to aid in the delineation of coal reserves. Coals tend to be mechanically weak, hence they are prone to borehole instability related problems during drilling, completion, and production operations. This paper includes a review of the mechanical properties of selected coals and provides two empirical cross-plots that can be used for estimating coal strength from index tests and geophysical logs. Linear elastic borehole stability models are demonstrated to be appealing because they are easily implemented, require a minimum of input data, and are well suited to rapid parameter sensitivity analyses. Using experience obtained drilling vertical wells in a given setting, a methodology is described for calibrating linear elastic models to provide realistic borehole stability predictions. Furthermore, as demonstrated using a western Canadian example (a shallow well in the Ardley coal zone), relatively simple elastoplastic models can be used effectively for borehole stability analyses. The important effects of filter cake, coal depth, and rock strength anisotropy are demonstrated with two different elastoplastic models.Key words: borehole stability, coal, methane, directional drilling, strength, stress.

<p>ROBOMINERS is developing an innovative approach for the exploitation of currently non-feasible mineral deposits. The approach entails the use of a robot-miner - a bio-inspired reconfigurable robot with a modular nature - in a new mining setting where the activities are nearly invisible and where mining presents less socio-environmental constraints, thus contributing to a more safe and sustainable supply of mineral raw materials.</p><p>The main aim is to design and develop a robotic prototype that is able to perform mining related tasks in settings including both abandoned, currently flooded mines not accessible anymore for conventional mining techniques; or places that have formerly been explored, but whose exploitation was considered as uneconomic due to the small-size of deposits, or their difficulty to access.</p><p>ROBOMINERS’ innovative approach combines the creation of a new mining ecosystem with novel ideas from other sectors, particularly robotics. At this point, work has been done to understand the best methods for the robotminer’s development in 1) biological inspiration, 2) perception and localisation tools, 3) behaviour, navigation and control, 4) actuation methods, 5) modularity, 6)autonomy and resilience, and 7) the selective mining ability. All these aspects combined aim to provide the robotminer XXI Century tools for mineral exploration and exploitation of (currently) unfeasible deposits.</p><p>At the same time, for the vision of a new vision of a mining ecosystem, work is involving studies on 1) developing computer models and simulations, 2) data management and visualisation, 3) rock-mechanical and geotechnical characterisation studies, 4) analysing ground/rock support methods, bulk transportation methods, backfilling types and methods, and 5) sketching relevant upstream and downstream mining industry analogues for the ROBOMINERS concept.  </p><p>After design and development, based on the previously mentioned studies, the robot-miner is set to be tested at targeted areas representatives which include abandoned and/or operating mines, small but high-grade mineral deposits, unexplored/explored non-economic occurrences and ultra depth, not  easily accessible environments. Possible candidates for testing purposes include mines in the regions of Cornwall (UK), mines in the Kupferschiefer Formation (e.g. Poland) or coal mines in Belgium.</p><p>When compared to usual mining methods the ROBOMINERS approach shows: 1) no presence of people in the mine, 2) less mining waste produced, 3) less mining infrastructure, 4) less investment, 5) possibility to explore currently uneconomic resources and 6) new underground small-sized mines, practically “invisible”. Altogether, ROBOMINERS can contribute to solve some of the main issues that make mining’s social license to operate so difficult to get in Europe: land-use, environmental limitations, and socio-economic aspects.</p>

Over the past decade, unmanned aerial vehicles (UAVs) have been used in the mining industry for various applications from mineral exploration to mine reclamation. This study aims to review academic papers on the applications of UAVs in mining by classifying the mining process into three phases: exploration, exploitation, and reclamation. Systematic reviews were performed to summarize the results of 65 articles (June 2010 to May 2020) and outline the research trend for applying UAVs in mining. This study found that UAVs are used at mining sites for geological and structural analysis via remote sensing, aerial geophysical survey, topographic surveying, rock slope analysis, working environment analysis, underground surveying, and monitoring of soil, water, ecological restoration, and ground subsidence. This study contributes to the classification of current UAV applications during the mining process as well as the identification of prevalent UAV types, data acquired by sensors, scales of targeted areas, and styles of flying control for the applications of UAVs in mining.

Core Mapping

The rapid mapping and characterization of specific porphyry vein types in geological samples represent a challenge for the mineral exploration and mining industry. In this paper, a methodology to integrate mineralogical and structural data extracted from hyperspectral drill-core scans is proposed. The workflow allows for the identification of vein types based on minerals having significant absorption features in the short-wave infrared. The method not only targets alteration halos of known compositions but also allows for the identification of any vein-like structure. The results consist of vein distribution maps, quantified vein abundances, and their azimuths. Three drill-cores from the Bolcana porphyry system hosting veins of variable density, composition, orientation, and thickness are analysed for this purpose. The results are validated using high-resolution scanning electron microscopy-based mineral mapping techniques. We demonstrate that the use of hyperspectral scanning allows for faster, non-invasive and more efficient drill-core mapping, providing a useful tool for complementing core-logging performed by on-site geologists.

The computer world is presently locked in a race to produce the futuristic fifth generation computer, one which will simulate some parts of human intelligence. At the back of this is the current interest in expert systems and their adaptation to petroleum exploration and development. Converging hardware and software technologies, combined with industry requirements, show a definite trend to move from the emphasis on hardware and operations systems toward software and informational systems. It is not possible to predict the precise form in which this will impact petroleum industry operations but it is certain that much greater analytical power and control will rest in the hands of the interpreters enabling much higher rates of productivity and effectiveness in the location of hydrocarbon reservoirs.
