Golden Square Equity Partners, a private equity fund that invests in technology, blockchain, biotech, natural resources and real estate, agreed to acquire Casa Mining, a gold exploration company, from Arc Minerals, a company focused on its copper exploration projects, for $50m. "Given the extremely challenging market conditions we are experiencing with Covid-19 this transaction is attractive to Arc with a potential $5m cash payment upon the maturity of the loan note in March 2021 and a potential royalty of up to $45m going forward, allowing us to share some of the future upside at Casa," Nick von Schirnding, Arc Minerals' Chairman.
