There is no Contessa or Condesa Mine. There is a deep orebody known as the Condesa Chimney that lies on the Condesa Trend (fault) but it is accessed solely through the principal workings of the Potosi Mine.

Distinctive gypsums, as well as limpid manganese-oxide and goethite-included quartz crystals, pale lavender spiky creedite and minor palid rhodochrosite come from the A-10 or Inglaterra Orebody of the Inglaterra Mine. At the time these gypsums were collected, the Condesa Chimney was actively mined so the general area became informally called "Condesa" by the collectors...but never the miners

There is continous mineralization between the Condesa Chimney and the Inglaterra Orebody...and continuous stoping, but the deepest workings of the Inglaterra Mine proper (ie where mineralization was extracted through the Inglaterra workings) are on the 5th Level of the Inglaterra, which is equivalent to the 10th Level of the Potosi Mine. The Condesa Chimney extends from the 10th level of the Potosi Mine down to below the 22nd level

The Inglaterra Shaft was almost exclusively used as a man-way and only for hoisting ore a long time ago (pre-1950s). After that the ore was extracted through the principal workings of the Potosi Mine. The Inglaterra Shaft had a watchman who was easily bribed and it was a popular entrance point for collectors trying to access the older Potosi Mine workings
