The comparison between collapse breccia
and bedrock revealed that although higher contents of P, Cr, Ba, Co, and Ni occurred in the collapse breccia
, they were lower than those in the sand-shale filling.
The 2013 core drilling suggests that the tabular zones of mineralized, favourable host rock are cut by one or more high-angle structures causing collapse breccia
zones where the mineralization becomes thicker and higher-grade.
13-11 and 13-08 confirm continuity of high-grade gold in the extensive, lower, flat-tabular, collapse breccia
body; which is analogous host material for many large Carlin-style deposits.
This lower breccia, which is comprised dominantly of collapse breccia
, is the preferred depositional environment for gold and the intercept in 13-08 is essentially open in all directions.
