Abstract
Every successful mining project begins with exploration and, at its core, with drilling. The coordination behind exploration drilling campaigns aims to identify potential geologic resources across mining operations while maintaining the highest standards of safety. As an Associate Geologist with CalPortland, calcium carbonate is one of the most essential raw materials necessary for cement production, which forms the backbone of clinker chemistry and product quality. To identify and evaluate CaCo3-rich zones within geologic formations throughout each of our operations, data collection methods include reverse-circulation (RC) drilling, rock chip sampling, field logging, and geochemical analysis. These steps are crucial to ensuring accuracy from the field to the laboratory and verifying that materials meet both compositional and operational standards. The resulting data are integrated into geologic models that guide mining engineers in determining ore-to-waste ratios and shaping future mine plans. This process illustrates how every rock chip, field log, and chemical analysis contributes to the larger picture of resource evaluation and sustainable mine development.
