Further Notes Concerning Ore-Shoots

Introduction A preliminary paper dealing with the subject of ore-shoots was presented to this Society at its Annual Meeting last year (1). The present paper records the attempts which have been made during the interval to further this study. In reporting this work, I wish to state that I do not consider the investigation complete; many more experiments will have to be carried out, and more field data will have to be recorded, before the geologist can say with confidence an ore-shoot should start at this point and pitch in that direction. The aim of these experiments is to find some criteria which will serve the mining engineer and mining geologist concerned with ore-shoots in hydrothermal veins.
