Tiny quartz found on the Goodradigbee (3,6)

I believe the answer is:

wee jasper

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

'goodradigbee' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'tiny quartz found on' is the wordplay.
'tiny' becomes 'wee' (I've seen this in another clue).
'quartz' becomes 'jasper' (type of quartz).
'found on' means one lot of letters go next to another.
'wee'+'jasper'='WEE JASPER'

'the' is the link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
