“…The exploration and description of outcrops and the cartography of the deposits were done using classical methods of geological survey linked to quantitative evaluation of geomaterials as clays (pit digging, auger drilling, boring holes, etc.). The reserve was estimated on the basis of the drill depth and the studied area [14,15]. During fieldworks, about sixty drillings were performed using a hand auger down to a maximum depth of 5 m. The different steps include: 1) implementation of the sample survey plan, 2) opening of transects providing access to sampling points, 3) realization of 60 pits of 3 to 5 m depth, 4) realization of two observational pits of 1 m 2 and 2 m depth.…”

“…The relevance of this information should not be underestimated, as this supports the interpretation of sample characterization results. Subsequent blending and homogenization of several samples together may reduce the resolution of the field observations [17].…”

“…During reclamation of clay from the stockpile, the excavator takes a cross section through all different layers and, thereby, receives a homogenous mix of the different clay qualities. All these common requirements can be adapted to an optimal exploration and mining model according to the actual clay deposit to be exploited and its potential use [36,37]. Open pit mining can enable simultaneous environmental renaturation.…”
