Considering where you purchased it and that description, it sounds like
a CTC (chopped leaf) black tea, like an English/Irish breakfast. Check
out some of the loose Twinings brand tea and see if it looks and tastes
similar, if you can.

IT is a tea that I acquired before I ever knew there were discussion
groups for tea, and before I ever heard of Pu-erh. it was chopped
fairly fine, in an unmarked cannister/jar I bought from a camping store

for small amounts of food. it is dark and I only have enough for two
cups left. sob. I don't think I have ever bought yerba mate so I
don't think that would be it, I believe is is actual Camelia tea.
