Where there's muck there's brass. (Brass is a slang and dialectal word for 'money' here.)

'Where there's muck there's brass' is a 20th century expression which originated in Yorkshire, England where brass is still used as a slang term for money. The expression is rarely used nowadays, although writers sometimes call on it when they want to establish a character as a blunt Yorkshireman. By 'muck' any form of dirt or manure may be implied, depending on context.

John Ray expressed the notion in A collection of English proverbs, 1678: "Muck and money go together." The expression was preceded by the 'where there's muck there's money' variant, which dates from the mid 19th century. (phrases.org.uk)
