What is the Value of Orebody Knowledge?

Orebody knowledge (OBK) is a holistic, interdisciplinary approach to understanding ore bodies, integrating geology, mining, metallurgy, and environmental data. It begins during exploration and extends across the mining value chain, serving as a critical enabler that creates value, minimizes risk, and maximizes recovery. The text discusses the various types of data collected during mineral exploration, including geophysical, geochemical, and geotechnical data, and how these data are used to develop comprehensive models of orebody domains. It also highlights the importance of advanced sensing technologies, such as hyperspectral data and downhole wireline geophysical tools, in providing high-resolution, near-continuous data to inform mineralogy, chemistry, and rock texture. The text explores the challenges in translating data into knowledge, including the difficulty of scaling data collected at variable resolutions and the siloing of data between mineral exploration and downstream users. It also discusses the financial and environmental risks associated with insufficient OBK, as well as the value of improved OBK in preventing or mitigating these risks. The text concludes with a review of case studies that illustrate the value of OBK in improving mining operations and reducing financial and environmental impacts. These case studies include the Olympic Dam mine, the Lihir gold mine, the Bingham Canyon Mine, and underground coal mining operations. The text emphasizes the need for better data management and collaboration across the mining value chain to fully realize the benefits of OBK.
