Since 2019, it is jointly owned by Rox Resources and Venus Metals Corporation, with the former managing the site.

[12] On 27 June 2000, Aquilia Resources Limited was listed on the Australian Securities Exchange, thereby becoming the owner of the mine, taking over from their parent companies, Quartz Mountain Mining Pty Ltd and Australian Mineral Investors Pty Ltd .

In October 2003, Aquilia sold the Youanmi mine, which it called its "Enterprise/Penny West Project", to Goldcrest Resources for A$2.75 million.

Parts of the Youanmi processing plant were to be relocated to Gidgee while the remainder would be used for the company's Aphrodite project.

Youanmi was to initially contribute 170,000 tonnes of ore to the future gold production, sourced from the existing underground operations below 600 meters, which would have to be dewatered and refurbished first.

[18][19] Subsequently, APEX returned to its previously abandoned strategy of sourcing ore from Gidgee as well as Wiluna for its processing facility.

[20] The company, at this point, had no immediate plans with Youanmi at the time and did not state whether it was still continuing to dewater the operation,[17] making a reopening now unlikely.

The company had a plan to do more drill work and seek business partners to reopen the mine.

[22] Rox Resources and Venus Metals had purchased the mine for A$4.8 million from private owners Oz Youanmi Gold.
