This well-illustrated book aims to enhance observations and understanding of structural features and proximity-indicator minerals, critical in exploration. The book provides a unique blending of different content on observational and critical aspects of data acquisition, geological, structural, tectonic set-up, mineral deposit types, geophysical framework, and proximity indicator minerals. Combining these topics led to a comprehensive understanding to facilitate mineral targeting and exploration in green- and brown-field terrains. Besides field photographs, the write-up is lavishly supplemented with relevant geological and geophysical maps, tables, and case stories in field geology, making it useful for a much larger section of the geoscientific community professional geologists and geophysicists, students, teachers, and also decision-makers in geo-surveys and exploration.

Geophysical data are presented for a number of deposits including the Batu Jijau, Elang, Grasberg, and Alumbrera porphyry copper-gold deposits; the Martabe and Yanacocha high-sulphidation epithermal gold deposits; and the Pajingo and Waihi low-sulphidation epithermal gold deposits. The physical properties of the mineralisation and alteration are discussed with emphasis on those properties that can be measured with standard exploration techniques. Mineralisation in porphyry Cu-Au deposits is commonly associated with magnetite that can produce strong discrete magnetic anomalies. This is usually within a zone of magnetite-destructive alteration that can be identified with a high-resolution magnetic survey. Magnetic surveys are also useful in defining regional structure and geology in the porphyry environment. Strong chargeabilities due to sulphides are typically associated with porphyry systems. Mineralisation and clay-pyrite alteration can produce strong anomalies, and late-stage and post-mineral intrusions can be mapped as chargeability lows within the system. These systems may be more conductive than the host rocks because of clay-pyrite alteration and sulphide veining, and airborne EM can be useful in locating and defining their extent. Gravity, radiometrics, remote sensing and topography may also be useful in exploration for porphyry Cu-Au deposits. In high-sulphidation epithermal systems gold is commonly associated with massive silica alteration. This alteration results in resistivities in the order of thousands of ohm-metres compared with background resistivities of tens of ohm-metres in argillic and propylitic alteration. Both ground resistivity and airborne EM surveys have been successful in locating and defining these deposits. Alteration in high-sulphidation epithermal deposits is magnetite destructive over a large area, although it does not appear to have a large vertical extent as the subdued character of the underlying lithologies can be observed. Typically, gold in low-sulphidation epithermal deposits is in thin quartz veins that are associated with major structures. The alteration associated with the veins is magnetite destructive, and high-resolution magnetics can be very useful and cost-effective technique to map the structures and alteration. Some deposits are associated with broad zones of magnetite destruction which is apparent in the regional magnetics. The mineralised quartz veins are within broader zones of silicification, and resistivity surveying can be used to map these zones. Generally, the high resistivity zones due to silicification are coincident with the structures identified in the magnetics. High-resolution magnetics and electrical surveys are the most useful geophysical techniques in exploration for porphyry and epithermal deposits. Airborne magnetic and EM surveys are fast and cost effective, particularly in areas of rugged topography. Regional magnetics, gravity, remote-sensed data and topographic data can also be used to identify major structures, intrusive complexes and alteration. Radiometric surveys can be useful in mapping geology and alteration.

Mineral exploration and mapping within thick glacial overburden, peatlands and different conservation areas is demanding, sensitive and expensive. The best practices for mineral exploration (techniques and concepts) from cost and environmental perspectives have been developed in the project "Novel technologies for greenfield exploration" funded by Finnish Funding Agency for Innovation (Tekes). Essential exploration techniques include the concurrent use of geological, geochemical and geophysical surveys. These techniques allow the location and thorough investigation of the geological processes responsible for mineral deposits and indications of ore-forming processes, or in suitable conditions, the direct identification of mineral deposits. The efficiency and success of exploration require not only high quality data processing and interpretation, but also the consideration of environmental aspects, which are particularly important in sensitive northern, sub-Arctic areas. The results and methodological advances arising from this project could particularly serve companies and organizations conducting grass root mineral exploration in a regional scale. The techniques can also be adopted in target-scale exploration.
