oregon

I'm a little stuck... Click here to teach me more about this clue!

'somewhere in the usa' is the definition.
I can't tell whether this definition defines the answer.

'gold for example regularly found' is the wordplay.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternate letters of 'found' are 'on'.
'or'+'eg'+'on'='OREGON'

Can you help me to learn more?
