I don't think that CIO are selling or intend selling the shares they got. This was their announcement below from their President which shows they believe that TYX can continue the mine and that they will benefit an upside for being TYX shareholders.

Mr Brett Hodgins, President and CEO, said “We are extremely pleased by the high value transaction entered into with Tyranna Resources for the sale of the Eureka Gold Project. This reinforces CIO’s strategy to create and realise value through mineral asset discovery, managing a portfolio of mineral assets, project development de-risking and commercialisation of those assets. This sale allows a focused exploration campaign on our higher priority exploration targets while maintaining exposure to a producing asset.”
