Machine Learning Algorithms and Their Application to

Traditional geostatistical estimation techniques have been used predominantly by the mining industry for ore reserve estimation. Determination of mineral reserve has posed considerable challenge to mining engineers due to the geo- logical complexities of ore body formation. Extensive research over the years has resulted in the development of several state-of-the-art methods
