Note that different ores will have drastically different density descriptors for the same ‰ reading.  For instance Deep Copper, Coal, and Sulfur will have Very High densities at around 18‰ and Very Poor below 5‰, while rare ores like diamond and emerald will be Very High at around 1.0‰ and Very Poor at 0.2‰.  These densities are based off of a density map that is generated with the world, at a resolution of approximately 32 blocks.  So when you find a reading, it should be similar for 4 or so chunks in the area.  The ore densities will tend to have a dense 'center' and then thin out moving away from that center.  So if you find a low density reading of an ore you want, try getting other readings some distance away in other directions, and see if you get a higher reading.  With enough sampling you can zero in on the center of the ore field.  These fields often span a great many chunks.  It is easiest to use this to find a good region, and then explore caves within that area.  But in a pinch, it can be used to blindly mine downward and hit veins of ores in solid stone areas.  Note that the propick only detects ores above a certain threshold.  You will occasionally run across ore deposits in a region when the propick did not show them to be present.  All ores occur everywhere, but the propick only detects them above a certain minimum threshold.  Such 'undetected' occurrences are very rare.
