Excellent post rcgl....
That completely blows Quady's arguments out of the water...especially re dividends, because he was asserting that this would start as an open cast mine...
"The fact that Alpala’s ore body is deep underground, coupled with its environmentally sensitive location in a virgin mining jurisdiction, means that Cascabel needs to be a subterranean mine."
Keith Marshall knows EXACTLY what he's talking about, as he is an expert on block caving, having been MD at Palabore and President of Oyu Tolguei...one of the biggest block cave mines in the world, where he will have learned massively from Rio Tinto's mistakes and steep learning curve...
"Rio Tinto will use block caving technology to mine the ore body. Block caving is technically complex, but it is also one of the safest and most cost-effective methods of mining ore from deep below the ground as it uses the force of gravity, according to the company."

"Keith's last two operational roles with Rio Tinto were as Managing Director of the Palabora Mining Company in South Africa (during its successful transition to block caving) and three years as president of the Oyu Tolgoi Project in Mongolia...."
This guy fills me with HUGE confidence, especially these two quotes:
“It’s very important to get the PFS right because once you move onto the Definitive Study it is very difficult to make any changes as you have lots of work streams going on in parallel.
The old plan for the PFS was “high risk”, explains Marshall. “It was high risk in terms of execution because it was aiming to build the world’s largest underground mine in a record time and that rang alarm bells in my mind. The plan for a mine like this needs to be robust, so we can build it on-time and on-budget."
And...
“The big advantage of block caving is the operating cost. It’s the cheapest form of underground mining, with operating costs typically between $5 to $10 per tonne. In fact, it’s the only underground method that can compete with open pit mining on cost. But it brings a level of complexity that can’t be underestimated. I’ve developed a lot of block caving mines and there is normally a bit of pain at the beginning before you get it right. Once everything is working the cost advantage is phenomenal and it usually makes for a very profitable mine."
Time to be patient...there is a firm hand on the tiller...
Watch him in two clips of this video...calm, considered, professional, highly knowledgeable...
