Weird coincidence...I live roughly 2-miles from Reed Gold Mine. This sounds like a lot of fun, I look forward to trying this out. I also have family who are geologists, we spend a lot of time vacationing near abandoned mica mines, and our hiking is frequently scored by the chip-tuned sounds of my uncle's hacked Geiger counter (he rigged it up with an ADC and micro-controller so he can hear not only counts-per-second, but also some other metrics he has mapped to the tone's pitch).
