While the Spruce Pine ore body is unique, recognition and careful selection of this resource is crucial to produce a consistent and continuous supply of IOTA® quartz. Strict exploration and selection criteria have been developed based upon correlation with end user information. Exploratory drilling is used to identify optimal ore sources. Drill core samples are utilized in our analytical services laboratories to simulate the full range of mineral separation and IOTA quartz production. With sophisticated geo-statistical modeling and proven iterative and predictive testing methods, assay results are used to confirm the quality of the ore. This rigorous testing ensures that only conforming ore will be sent on to the mineral separation process.
Through detailed mine planning, exploration and land management, Unimin maintains decades of reserves in order assure long-term and sustainable supply to the market.
