Panning, essentially for large kilo of gold here? (10)

'panning essentially for large kilo of gold here?' is the definition.
The definition suggests a singular noun which matches the answer.

'large kilo of gold here?' is the wordplay.
I cannot really see how this works, but
'large' could be 'lg' (abbreviation) and 'lg' is present in the answer.
'kilo' could be 'k' (phonetic alphabet: alpha, bravo, charlie etc.) and 'k' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
'gold' could be 'or' ('or' is the heraldic name for gold) and 'or' is present in the answer.
The remaining letters 'alie' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
