Colleen Sullivan, former CEO of crypto trading firm CMT Digital, has resigned as a non-executive director of Argo Blockchain, the London- and Nasdaq-listed crypto mining firm.
Argo announced Sullivan’s appointment on July 29 this year, hailing the wealth of crypto and finance experience she would bring to the firm.
But in an announcement this morning, Argo said Sullivan had stepped down to focus on other roles.
“She has taken on a new career role that does not allow her to serve as a director for the company and her resignation is not the result of any disagreement with the management or board of the company,” said the company.
Sullivan joined British hedge fund Brevan Howard Asset Management to steer its crypto investments in September. She had run CMT Digital, a division of CMT Group, since September 2017.
In the Monday announcement, Argo also stated that it had mined 167 bitcoin or “bitcoin equivalent” in October, bringing the total amount of bitcoin it has mined this year to 1,646. Revenues for the month came in at £7.24 million (or roughly $9.75 million).
Last week, the company was forced to disclose key information about upcoming projects after the contents of a private meeting were unexpectedly posted on Twitter.
