Asteroid Belt Remnants
From EVE University Wiki
Asteroid Belt Remnants is an ore anomaly that spawns in 1.0 and 0.9 security systems, usually near "Rookie systems". Rookie systems list can be found here [1]
It only contains veldspar asteroids and a few of its richer variants (concentrated & dense).
There is about 60 asteroids on the grid and they are quite scattered. This anomaly can also spawn in 0.8 and 0.7 but never below.
