Which procedure is withdrawn is unknown. They don't provide exact meanings of their "tipo de acto". Yes, the updates to the mining registry are shown quicker now. Also, I see on a title 244976 a date of today (September 22nd 2019) but I also saw it last week:

Tipo de Acto : EN TRAMITE (in process)

Partes:CESAR OCTAVIO IÑIGUEZ ABARCA
CONCESIONARIO DESCONOCIDO (unknown licensee)

The registry should be checked more regularly now as they update quicker.
