ProspectorInfo is a Vintage Story mod by P3t3rix. ProspectorInfo records prospecting results on your client and adds them to the world map, with an optional ore-density heatmap.
Why this mod is worth installing
This QoL mod is useful for miners who prospect several areas and do not want to copy chat results into notes. It works clientside, so your records remain available to you without changing the server.
What ProspectorInfo adds
After you use a prospecting pick, ProspectorInfo reads the resulting chat message and stores the data in the client’s ModData folder. The same information is attached to the corresponding chunk details on the world map, so ore findings can be checked later instead of being remembered manually.
Prospected chunks receive a transparent square overlay, making explored areas easy to recognize on the map. If you prospect the same chunk again, its previous entry is replaced with the newer result; the overlay can be switched on or off with the mod’s .pi command.
The optional heatmap map mode turns recorded ore values into a color gradient. You can view the relative density for a selected ore or let the mode compare all recorded ores and show the strongest value for each chunk.
Usage
Prospecting results are saved locally and added to the world map’s chunk information. Transparent squares mark chunks that have already been surveyed, while a repeat survey replaces the stored message.

Heatmap
The heatmap map mode uses a color gradient to show relative ore density. It can focus on one ore or display the strongest recorded ore value in each chunk.
