In the sample above you wrote LC_MESAGES instead of LC_MESSAGES (notice the double S), I believe this very well could be your issue.

If not then read on!

I had this issue (again!) recently, and the answer was found in this part of the django documentation

I suspect you have the same issue since your "admin" app was translated but not your own (project) app.

It seems that Django is looking for your translations like so:

1. The directories listed in LOCALE_PATHS have the highest precedence, with the ones appearing first having higher precedence than the ones appearing later.
2. Then, it looks for and uses if it exists a locale directory in each of the installed apps listed in INSTALLED_APPS. The ones appearing first have higher precedence than the ones appearing later.
3. Finally, the Django-provided base translation in django/conf/locale is used as a fallback.

With the settings you described above, you must make sure your tree looks something like this (with the most important being settings.py is in the dir above the 'locale' dir):

+-project_top/
  |
  +-project_app/
  | |
  | +-locale/
  | | |
  | | +-pt_BR/
  | |   |
  | |   +-LC_MESSAGES/
  | |     |
  | |     +-django.po
  | |  
  | +-settings.py

  +-manage.py
