The sign over the tunnel in the Bandera Video appears appropriately weathered.
Conversely, in examining the SRGE vid, the sign looks fresher. It is quite possible that they either doctored the video, or had a sign made and attached it to the overpass wall, just for the video.
quikfix, first interesting observation. Second the Bandera video seems to reflect the state of the Cinco Minas in that the mining is suspended at this time.
I believe that there is no mining going on at Cinco Minas and hasn't been for quite some time.
I find it interesting the editing of the video by Southridge - it is just odd how it is put together - there is nothing continuous to show any mining going on.
On the video they take some stills and pan and zoom to give the effect of video but it just a still photo.
