Are there any copper-rich asteroids out there?

> Asteroids have since long been considered to host significant resources of siderophilic elements such as Fe, Ni, Co, Cu, that could be exploited in situ. However bulk rock mining would be largely impractical. In this paper, we report on abundance and mineral occurrences of copper in H chondrites, identify Cu carrier minerals and interpret their distribution in the context of processes that must have affected parent bodies. This leads us to suggestion that some parts of S-type asteroids contain Cu in a form and amount that would satisfy requirements of potentially economically and environmentally more efficient exploitation.
