According to the articleby Adn Muoz, mining supervisor of AYMA Mining Solutions, and Benjamn Cebrin, of Blast-Consult, "it is our responsibility to design, control and to measure the dilution that results in what we do and how we operate". In other words, the dilution present in minerals is a determining factor for mining operations and extracting processes.

Mining dilution affects the economy of mining projects in many ways. For example, dilution increases costs and can cause reconciliation issues that are common in mining operations. A common approach to estimating mining dilution is to apply a fixed factor to the entire block model. The fixed dilution factor is usually driven by assumptions that are made based on

Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

Dilution and ore loss have an important bearing on the success of open pit mining projects. Their impacts on production costs, revenues and production rate require that they are correctly modelled in the long-term mine plan. The estimation of dilution and ore loss is therefore an essential part of any Ore Reserve estimate or mine schedule.
