Ann: Quarterly Cashflow Report, page-41

cut n paste
"Licence agreement enables Lucapa to be repaid all past and future alluvial exploration and development expenditures from free cash flow"

if this said "shareholders agreement" ( JV ) i would be in 1Share1 school of thought
but it says Licence agreement
so the agreement looks like its is between the govt and the holders of the licence

and that looks like the JV to me

cut n paste
"Lucapa and its mining partners Endiama (the Angolan Government’s diamond concessionary) and Rosas & Petalas (a private company controlled by Angolan lawyer Dr Celso Rosas) signed the diamond mining licence agreements in a ceremony held in the Angolan capital of Luanda late on Friday (21 November 2014)"

i think lucapa is not making a very clear distinction between lucapa and lulo JV in the announcement 26 November 2014
in fact it looks as clear as mud

i guess an email to lucapa may clear it up
