Today I mined out an abandoned mineshaft for iron ore to power my beacon. Strangely, in a timespan where I might find 1-2 stacks of iron ore through mining in normal caves, I found almost 4.
I heard a rumor a while back (no idea where it came from) that more ores will spawn near these structures. However, I was thinking that this abundance could also be due to the fact that abandoned mineshafts have a lot of surface area compared to a typical cave of comparable volume, and therefore more of the ores that already generated spawn naturally. It could also be that the mineshaft was higher than the level I usually mine at; normally, I mine at layer 10, but in this case I was somewhere between layer 30 and layer 50. Finally, this could also be purely anecdotal, e.g. I was mining for longer than I thought I was, or I simply got lucky.
So because I still need another half-stack of iron blocks to bring a beacon to full power, I'd like some input on the source of this sudden influx. Would my high yield in the aforementioned mining trip be attributed to:
- The high surface area,
- The higher elevation,
- My bad memory and/or luck,
- Or that I was mining in an abandoned mineshaft?
