It would be great if someone could come up with an idea if I am right or wrong.
Looking forward for some replies

In the Mindat locality list, the reference given for Wheal Tamar is Golley and Williams (1995) Cornish Mineral Reference Manual. However, checking my copy of this reference there is no listing of Wheal Tamar under chalcophyllite. Nickel and Nichols (1991) give the earliest descriptive reference as Breithaupt (1841), or at least the first one in which the name chalkophyllit is used. 1841 would suggest Vol 2 of Breithaupt's Vollstaendiges Handbuch der Mineralogie. Dana's System of Mineralogy suggests Breithaupt's Volume 3 (1847) and page 149, if you can find a library with this old text. It's also possible the type locality was in Germany (Schmiedeberg or Mordelgrund) since these are the first localities given in several texts.
Cheers,
Ben.

Also forgot to mention in Greg and Lettsom (1958) the mineral is listed as tamarite, however, they suggest the source of that name is sketchy. I'll quote them directly: "The name Tamarite is the one proposed by Brooke and Miller for this mineral, but what connexion there may be between the Tamar, or any of the Tamar mines, and the species in question, is by no means obvious."
