In this work, we create a quality map of a slate deposit, using the results of an investigation
based on surface geology and continuous core borehole sampling. Once the quality of the …

Slate is one of the most popular natural roofing materials, because of its ability to be split into
large, thin and waterproof tiles. However, while some slate roofs last up to two centuries …

Investigation of deposits for traditional extraction activities (metals and coal) has generally
been based on determining grade, or content, of the required material. In order to apply the …
