Small ores can be found scattered around on the surface of the ground. These are samples of what ore veins are located within 35 blocks underneath the soil, so they're somewhat important. In the majority of cases, it is a sample of a vein in the top layer of stone. However, in areas where the top layer is thin enough, the vein may be located in the upper section of the middle stone layer.

The ores were practically free from antimony and bismuth: There was thus about 90 per cent, of the total arsenic eliminated in the operation. About 80 tons of slag were produced with 100 tons of ore, and this contained 0.53 per cent, arsenic, or about 0.43 ton. About 54 per cent, of the arsenic was eliminated in the slag.
