Thank you for the question.
The contract has evolved over time. When it first started and we won the contract for the 17 million dollars' worth of scope, as you mentioned, it was for removal of a portion of the rock in the river. We were able to successfully execute that and remove more than anticipated. I believe I mentioned that approximately 14,000 cubic metres was addressed in the river, of the total rock that's down there. Then, as you understand from the Mother Nature comments, water levels were coming up and that rock removal operation was paused at that time.
Then we were asked to price and build additional scope around what was described as the Whooshh system. That was an approximately $30-million scope to do the mechanical transportation over the remaining rock. The third piece that I mentioned in my opening remarks is really about follow-on site management to help as we collaborate and discuss what the next step is.
We do not have any scope to do a permanent fish ladder at this point, or to do some of the other things that are being brainstormed. I'd just like to say on behalf of the company that if those things are of interest to the committee and to DFO down the road, we are absolutely open to discussing them to help the situation.
