Yes a current valuation I've read was roughly $680m yet current SP is $390m
Not sure if this has to do with funding expectations ? With development costs expected to exceed $1B or to do with the agreement lundin came to with Equador where 50% minimum is to go to equador
Including advance royalty payments of $65m
• The right to develop and produce gold from the FDN Project for 25 years; this right
can be renewed
• An advance royalty payment of US$65 million to the Government of Ecuador, with
$25 million being due upon execution of the Definitive Exploitation Agreement
• A royalty equal to 5% of net smelter revenues from production, payable to the
Government of Ecuador

• The Government of Ecuador's share of cumulative benefits derived from the FDN
Project will not be less than 50%. To the extent that the Government of Ecuador's
cumulative benefit falls below 50%, Aurelian will be required to pay an annual
sovereign adjustment. Each year, the benefits to Aurelian will be calculated as the
net present value of the actual cumulative free cash flows of the FDN Project
subsequent to the signing of the Definitive Exploitation Agreement, net of the
cumulative investment incurred in the development of the Project from its inception
until the date of the Definitive Exploitation Agreement. The Government of
Ecuador's benefit will be calculated as the present value of the cumulative sum of
taxes paid including corporate income taxes, royalties, Windfall Tax, labour profit
sharing paid to the State, non-recoverable value-added tax (VAT; IVA in the
Spanish acronym), and any previous sovereign adjustment payments.
