"We are pleased to report yet another record year of income for Anglo Pacific, the second year in a row in which we have done so,” said Anglo Pacific’s chief executive Julian Treger.
“Including the cash received from the Denison financing arrangement, total portfolio contribution for the year is expected to be between £57mln and £59mln, which represents growth of around 20% on the £49.3mln generated in 2018. The strong levels of cash generated in 2019 enabled us to use our balance sheet to acquire £62.5mln (US$75mln) in income generating royalties. In the same period, we paid out £14.4mln (US$18.5mln) in dividends. Our balance sheet remains in a very strong position,” he added.
