Exploration / Data Acquisition
Mining exploration and data acquisition involve systematic processes to identify and evaluate mineral deposits. This includes geological mapping, sampling, and geophysical surveys to gather crucial data on resource potential.
Advanced technologies, such as remote sensing and drilling techniques, are employed to enhance accuracy and efficiency. The collected data informs feasibility studies and resource assessments, guiding investment decisions. Ultimately, these activities play a vital role in ensuring sustainable and economically viable mining operations.
Geological Services
Geological services for resource estimation and mine modeling involve evaluating mineral deposits to determine their quantity and quality. Using geological mapping, sampling, and advanced software, these services create 3D models of ore bodies, providing a detailed understanding of the deposit’s potential.
Accurate resource estimation is essential for feasibility studies, investment decisions, and mine planning. These services ensure efficient extraction while minimizing waste and environmental impact, optimizing overall mine operations
JORC/ KCMI/ SNI/ VALMIN
Statutory reports like JORC, KCMI, SNI and VALMIN are essential in mining to ensure transparency, accuracy, and compliance with industry standards. These codes provide guidelines for the reporting of exploration results, mineral resources, and ore reserves, ensuring that estimates are reliable and consistent.
JORC, KCMI, and VALMIN (for valuation of mineral assets) are recognized globally and are often required for investment, regulatory approval, and financial reporting. These reports instill confidence in stakeholders, including investors and regulators, by providing standardized, well-documented assessments of a project’s economic potential and associated risks.
Mine Planning / Scheduling
Mine planning is the process of designing and organizing all aspects of a mining operation, from exploration and resource estimation to extraction and reclamation. It involves creating detailed plans for production, scheduling, infrastructure, and equipment requirements.
Effective mine planning ensures the safe and efficient extraction of minerals while minimizing costs and environmental impact. It plays a key role in optimizing resource recovery, ensuring regulatory compliance, and maximizing the economic value of the project.
