I think it is, but here goes ennyhoo ... about 8 hours of in-town mining LA/Tram Delucia. the same 4 spots either a) dropped valorite right off or b) prospector tool upgraded from verite. this is over 3 mining passes in Del to W. Brit and back to Del. 95.4 real Mining using +5 gloves and I was surprised as all get out at the repetition. almost every other colored ore vein changed from one trip to the next but not these. tell me I'm not crazy and these were REALLY a fluke. please?
