Joe Mann Mine Sampling (February 2021):
The Joe Mann mine ceased operation in 2007 after having produced 1.2 million ounces of gold (4.75 Mt of ore grading 8.26 g/t Au and 0.25% Cu).
Water was sampled down the shaft each 100 meters right down to the deepest growth degree of 1,150 meters for a complete of 12 samples. Video inspection indicated that the shaft is in glorious situation. The common pH was 7.35, indicating a barely primary water chemistry.
