The Woods Point gold deposit, Victoria, Australia

Conclusions:
The quartz samples from the Woods Point mineralization occurrences have low temperature decrepitation peaks which are caused by the presence of substantial amounts of CO2 in the fluids which deposited the quartz vein and gold mineralisation. Samples with high gold contents also have high CO2 decrepitation peaks and it is clear that the presence of CO2 rich fluids would be an effective exploration method to explore for extensions of the known deposits or to explore for additional new deposits in the region. Because the distribution of CO2 rich fluids is wider and more homogeneous than the distribution of Au itself, it is advantageous to use CO2 analyses in exploration because of the larger and more consistent target size of CO2 anomalies.
