A fixed version of adamius's Ore manager mod ( https://mods.factorio.com/mod/ore-manager ). I take no credit for the creation of the mod, as I only fixed the ore search formula, so it no longer picks up all ore/oil patches of the same kind on the map.

!! ATTENTION !!
It is still not foolproof. Too many separate patches of the same kind close to each other may cause the bug to re-appear. If you see such patches, please save your game before use.

From the original mod's page:

Utility to move ore resource patches with precision.

Store: create a ore manager chest, place it on a ore patch and the ore will be imaged and stored.
Retrieve: place a ore manager chest on bare ground and the stored ore patch will be restored.

This is mostly a utility tool. It should work in single player or multiplayer. In multiplayer it is currently an admin-only tool.

A few rough edges remain.
