The average player at Cam Torum’s calcified rocks seems to collect about 2,000 blessed bone shards per hour , with a rough AFK range of 1,500 to 3,000 shards per hour depending on Mining level and focus. Since each shard is worth 5 Prayer XP, that works out to about 7.5k to 15k Prayer XP per hour.

What the community is reporting

Players discussing the method commonly describe it as a relaxed, AFK-friendly way to bank prayer materials rather than a top-tier Prayer training method. One report said they were getting “around 2,000 shards per hour,” while another guide estimated 1,500–3,000 shards per hour when doing it AFK.

What that means in practice

A simple rule of thumb is:

  • Low AFK: about 1,500 shards/hour.
  • Typical AFK: about 2,000 shards/hour.
  • Better setups: about 3,000 shards/hour.

At 5 Prayer XP per shard, that translates to:

  • 7,500 Prayer XP/hour
  • 10,000 Prayer XP/hour
  • 15,000 Prayer XP/hour

Quick context

A few players also reported higher prayer XP rates once they actually cash in the shards, but that depends on how fast you convert or use them, not on the mining rate itself. The main draw is that it is chill and stacks up prayer supplies while you train Mining.

TL;DR: expect roughly 2,000 bone shards per hour on average , with a practical range of 1,500–3,000 shards/hour.
