mid 19th century: apparently from dialect nug ‘lump’, of unknown origin.
wiktionary
Probably a diminutive of dialectal nug(“lump, block”) + -et.
etymonline
nugget (n.)
1852, "lump of gold," probably from southwestern England dialectal nug "lump," a word of unknown origin [OED]. Another theory is that it is from a misdivision of an ingot. Transferred sense (of truth, etc.) is from 1859.
