Most of the concession titles have changed. The date is Sept 18th 2019 and you see "Desistimiento de tramite". We'll have to wait and see what that really means. GoGold was about to take over the mines completely as per this press release https://gogoldresources.com/investors/press-r...s-property.
The parties are Grupo Zafermex S.A. de CV (must be the party of Cesar Octavio Iniguez Abarca) and Minera Durango Dorado S.A.de CV. Minera Durango Dorado S.A.de CV is a 100% owned Mexican subsidiary of GoGold Resources (https://gogoldresources.com/investors/press-releases/2012/58-gogold-resources-adds-to-property-position-at-the-san-diego-project-durango-mexico).
