Ann: Centaurus Secures Nickel-Cobalt Development JV at Itapitanga, page-23

Copied from AUZ thread:

Australian Mines Limited (“Australian Mines” or “the Company”) is pleased to announce it has engaged one of Australia’s leading hydrometallurgical and processing companies, The Simulus Group, to today begin construction of a $2 million demonstration-size cobalt-nickelscandium processing plant in Perth, Western Australia.

About Simulus:Simulus also has an extensive due diligence and competent person reporting reference list of over 100 projects. Simulus has developed flowsheets, engineering studies and conducted project assessments for projects in over 35 countries for over 150 companies.

Looking at their credentials I don't think they have just taken a wild guess on how long it will take to build the plant and at what cost and I am almost certain they know the answers to all your questions and are confident they can deliver.

Another poster asked why the demo plant is being built in WA:Managing Director Ben Bell said“The reason for constructing the demonstration-size plant in Perth was due to the relevant metallurgical expertise available in Western Australia, including The Simulus Group some of whose staff were involved in the early operating stage at Glencore’s Murrin Murrin nickel and cobalt operation."
