RE:Underground Mining and Gold Production in the Goudreau Lake The report indicates that the deepest drilling reached a depth of about 500 ft or 152.4 meters. While this might not seem very deep, the drill hit a high-grade deposit. This allowed them to establish a reserve of 1,747,170.6 tonnes at 8.6 g/t, translating to 483,087.6 ounces of gold. This achievement is quite remarkable.
