- n. In mining, a body of ore, commonly of elongated shape, within a vein: usually applied to the workable portions of a vein only.
Sorry, no etymologies found.
If this could be taken as the usual occurrence, it would be possible (eliminating the evident exceptions mentioned above) to state roughly that the minimum extension of an ore-body or ore-shoot in depth below any given horizon would be
For instance, in the A mine, with an ore-shoot 1000 feet long and 10 feet wide, on its bottom level, the minimum extension under this hypothesis would be a wedge-shaped ore-body with its deepest point 500 feet below the lowest level, or a minimum of say 200,000 tons.
"Straight cyanidin 'proposition, averagin' $60 to the ton with a tunnel cross-cuttin 'the ore-shoot at forty feet that samples $80 where she begins to widen --" Lack of breath prevented Porcupine Jim from saying that the hanging wall was of schist and the foot wall of granite and he would take $65,000 for it, if he could have 10 per cent. in cash.
But a "fault" had come into the vein on the Mascot and they had never been able to pick up the ore-shoot again.
The vein is nearly twenty feet wide at the surface; below, the ore-shoot has a width of five to twelve feet, and consists of alternate bands of ore, slate and quartz, the ore seams being from three to eighteen inches thick.
One possible interpretation for the large intersection found is that of an ore-shoot or 'clavo.'
The first ore-shoot at San Marcos has been intersected over a strike length of 300 meters and is open to the east and to depth.
