The Mexican Assets, page-7

CHN did two capital returns over an 8 month in 2018-19 because they felt they had more cash than was needed to keep their exploration activity going. The cash came from the sale of assets in Quebec that they gave up in order to focus on the Bendigo area. This was before they discovered Julimar.
Unlikely to happen with AZS when/if they sell the Mexico assets unless Tony wants the money to put into other non-AZS ventures.
