What is an inferred resource? A resource where the quantity and grade can be estimated with confidence using inspection sites that are situated far apart - AQA - A-Level Geography - Question 5 - 2018 - Paper 2

An inferred resource is a type of resource estimation used primarily in geology and mining. It is characterized by the level of confidence in the estimation of its quantity and quality, which is derived from limited geological sampling. In this context, the resource assessment is not based on extensive data collection, making it less certain than other classifications, such as measured or indicated resources. Thus, while there may be an understanding of the potential of the resource, there isn’t enough reliable information to confidently justify the investment in its extraction.
