Amy Winehouse Lioness: Hidden Treasures, a collection of previously-unheard recordings made by the singer during her lifetime, was released on Monday (December 5).
Her family confirmed upon its unveiling in October that £1 from every sale would go to The Amy Winehouse Foundation, which aims to help people battling drug addictions.
Taking to Twitter today (December 6), Mitch updated fans on the success of the LP and what it would mean for the charity.
"Just been told. Amy at number 1," he wrote. "140,000 sold = £140,000 to foundation in one day. Well done baby."
Mitch earlier thanked followers on the social networking site for their "wonderful responses" to Lioness: Hidden Treasures.
Amy Winehouse died on July 23 at the age of 27 from alcohol poisoning.
