Through his New York-based corporate advisory firm, Sugar has also advised other Australian companies like Crusader Resources and Talga Resources.
Sugar said he was looking forward to working with Rumble to assist in building a major nickel company.
“The Fraser Range is one of the standout nickel exploration destinations in the world, with the region underexplored and to date only has one world class nickel discovery,” he said.
“The North American market is well versed on nickel discoveries which have a close affinity to the Canadian nickel belts that host the word class Thompson, Raglan and Voisey’s Bay nickel deposits.
“I believe there is a great opportunity to find multiple nickel discoveries in the Fraser Range, and hopefully replicate the Canadian experience in Western Australia.”
It follows the appointment of former coal billionaire Tinkler as a strategic corporate adviser.
Like Tinkler, EAS will be paid in performance options, exercisable within 18 months.
Rumble CEO Shane Sikora said he was excited to have appointed EAS.
“I am delighted to work with a group as well respected in the resources and investment market as EAS,” he said.
“EAS and Eddie have a long history of backing successful mining entrepreneurs and will work with our recently appointed corporate adviser Nathan Tinkler to significantly lift the exposure of Rumble to the global capital markets.”
Planning is already underway for a North American roadshow.
Shares in Rumble jumped nearly 17% to A7.6c.
