I despise the idea of a marker system. Part of the charm (minigame) of miner is to use the ability to "sense" a node and hunt it down, then play the "hot and cold" minigame to mine the items. This idea is one more step to a pathetic easy mod for an already overly easy DoH. This idea goes against the spirit of minings original concept, which was actually a good one, and the class and its ability to do its job is great right now, without bad ideas like this.
