Figure 1 – 309 Deposit Hydrothermal system model. 1 A–D show variation in mineralization styles across the deposit with sample locations shown on 1E. Abundant bladed fluorite and fluorite replaced by silica forms in a distinct zone that we interpret to result from boiling. The fluorite-rich boiling zone marks an inflection point in deposit geometry above which mineralization forms two pipe-like bodies along ax NNE trend (1E and F). Note that elevated gold grades form in layers sub-parallel to the inflection horizon/boiling zone. 1F schematic model displays the spatial relationships of key mineralization features at 309.
