Cut Off grade at L1 is practically the same write up on pages 146 and 147.

"Given the early stage of the project’s history, no detailed information is available in respect of many of the important input parameters required to prepare an accurate cut-off grade estimate such as operating costs for mining, processing and general and administration, metallurgical recovery, smelter accountabilities, freight and refining charges, and the like in respect of a potential open pit mining operation."

..........assumed values will likely change as new information is obtained as a result of further work."
