Borrasca
Borrasca in Spanish means storm, squall, depression, or area of low pressure. But apparently it can also mean an exhausted mine, and 'Going borrasca' means "becoming mined-out". Interestingly, this is very close to the English word 'borassic', ie. out of cash. This comes from Cockney Rhyming Slang: 'boracic lint' meaning 'skint', ie without any money.
