An Exploration Geologist is a scientist who specializes in locating and assessing mineral and energy resources, such as oil, gas, metals, and gemstones. They use a combination of geological knowledge, fieldwork, and advanced technology to evaluate the potential of a given area for resource extraction. Their work is essential in the early stages of mining and drilling projects, providing critical information to guide investment and operational decisions.
Duties
Exploration geologists typically do the following tasks:
Conduct geological fieldwork to collect samples and data, mapping the geological features of potential exploration sites.
Analyze rock, soil, and core samples to determine mineral content and identify indicators of resource deposits.
Utilize geophysical surveys, geochemical analysis, and remote sensing technologies to gather subsurface data.
Interpret geological data to create maps, cross-sections, and reports that outline the location, size, and quality of resource deposits.
Plan and oversee exploration drilling programs, ensuring the collection of accurate and representative samples.
Estimate the quantity and quality of resources present, using mathematical models and software to assess economic viability.
Evaluate the potential environmental impact of exploration activities and ensure compliance with environmental regulations.
Prepare detailed technical reports and presentations for stakeholders, including investors, engineers, and regulatory agencies.
Coordinate with other professionals, such as engineers, surveyors, and environmental scientists, to ensure successful project execution.
Stay updated with and implement the latest exploration technologies and methods to improve efficiency and accuracy.
Exploration Geologists often work in remote and challenging locations, such as deserts, mountains, forests, and offshore sites. Fieldwork can involve extensive travel, sometimes for weeks or months at a time, and requires physical stamina and adaptability to various environmental conditions. Safety is a paramount concern, with geologists required to adhere to strict safety protocols and use personal protective equipment (PPE) during field activities. Office work involves analyzing data, preparing reports, and planning exploration activities. The role can be demanding, with irregular hours and the need to meet tight project deadlines. Collaboration with multidisciplinary teams is common, requiring strong communication and interpersonal skills.
A bachelor’s degree in geology, earth sciences, or a related field is typically required, with many employers preferring candidates with a master’s degree or higher. Specialized coursework in mineralogy, petrology, structural geology, and geochemistry is beneficial. Practical experience through internships, fieldwork, or entry-level positions in the mining or oil and gas industries is highly valued. Proficiency in geological mapping, data analysis software, and the use of geophysical and geochemical equipment is essential. Strong analytical and problem-solving skills are crucial for interpreting data and making informed decisions.
Continuous professional development and staying current with advancements in exploration techniques and technologies are important for career advancement. Membership in professional organizations, such as the American Association of Petroleum Geologists (AAPG) or the Society for Mining, Metallurgy & Exploration (SME), can also provide networking and educational opportunities.
ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:
the nature of the work performed in an occupation in relation to the characteristic tasks and duties
the level of formal education required for competent performance of the tasks and duties involved and
the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.
Exploration geologist is a Skill level 4 occupation.
These skills are necessary for the role of exploration geologist.
Examine geochemical samples: Analyse laboratory samples using equipment such as spectrometers, gas chromatographs, microscopes, microprobes and carbon analysers. Determine the age and characteristics of environmental samples such as minerals, rocks, or soil.
Use earth sciences tools: Employ a number of tools for example geophysical, geochemical, geological mapping and drilling to discover a mineral deposit.
Apply strategic thinking: Apply generation and effective application of business insights and possible opportunities, in order to achieve competitive business advantage on a long-term basis.
Evaluate mineral resources: Search for mineral resources, including minerals, oil, natural gas and similar non-regenerative resources after obtaining legal rights to explore in a specific area. Endorse the assessment of the mineral reserves.
Negotiate land access: Negotiate with landowners, tenants, mineral rights owners, regulatory bodies or other stakeholders to obtain permission to access areas of interest for exploration or sampling.
Interpret geophysical data: Interpret data of a geophysical nature: Earth’s shape, its gravitational and magnetic fields, its structure and composition, and geophysical dynamics and their surface expression in plate tectonics.
Address problems critically: Identify the strengths and weaknesses of various abstract, rational concepts, such as issues, opinions, and approaches related to a specific problematic situation in order to formulate solutions and alternative methods of tackling the situation.
Build business relationships: Establish a positive, long-term relationship between organisations and interested third parties such as suppliers, distributors, shareholders and other stakeholders in order to inform them of the organisation and its objectives.
Advise on geology for mineral extraction: Provide advice of the impact of geological factors on the development of mineral production. Take into account factors such as cost, safety, and characteristics of deposits.
Complete initial resource statements: Comply with all regulatory requirements when completing an initial resource statement, an assessment of the quantity of valuable minerals present.
Conduct environmental site assessments: Manage and oversee environmental site prospection and assessments for mining or industrial sites. Designate and demarcate areas for geochemical analysis and scientific research.
Model mineral deposits: Geologically model mineral deposits in order to determine their location, their aspect and their economic potential.
Determine characteristics of mineral deposits: Prepare and conduct geological mapping, logging, sampling and assay of drill core and other subsurface rock samples. Analyse results in plans and sections, with particular emphasis on geostatics and sampling theory. Examine in 3D the maps, deposits, drilling locations or mines to determine the location, size, accessibility, contents, value and potential profitability of mineral deposits.
Negotiate land acquisition: Negotiate with landowners, tenants, mineral rights owners or other stakeholders of land containing mineral reserves in order to buy or lease the land.
This knowledge is sometimes, but not always, required for the role of exploration geologist. However, mastering this knowledge allows you to have more opportunities for career development.
Archaeology: The study of the recovery and examination of material culture left behind from human activity in the past.
Economics: Economic principles and practices, financial and commodity markets, banking and the analysis of financial data.
Minerals prices: Prices of metals and minerals and associated production costs.
Chemistry: The composition, structure, and properties of substances and the processes and transformations that they undergo; the uses of different chemicals and their interactions, production techniques, risk factors, and disposal methods.
Logging: The process of felling, cutting trees and transforming them into timber, including mechanical felling and processing.
