Drops per mined section

Item	Amount	First draw chance
石	1-1	66.67%
銅鉱石	1-1	33.33%

100% chance to run this table, with 2-4 draws. Amount bounds are per harvest stage at the normal resource rate. World drops use rounded rolls, so amounts within a range need not be equally likely. Entries can be selected again on later draws. The displayed chance is conditional on a draw, not the chance of obtaining the item.
