Highlands Pacific - Woodlark Royalty Entitlement

Highlands Pacific (ASX:HIG) announcement on 10 March:

"Highlands Pacific Ltd (ASX:HIG) has identified an entitlement to a royalty from gold produced at the Woodlark Gold Project in PNG after the review of agreements relating to previously held exploration ground. The royalty is an amount of A$10 per ounce in respect of the first 200,000 ounces produced from the area of the former exploration tenement EL455 at Woodlark Island in Milne Bay Province. Highlands' precedent companies held an interest in EL455 in 1995 prior to the sale of the exploration tenement and the associated creation of a royalty entitlement. Highlands has notified Kula Gold Ltd of its entitlement to the royalty, which was outlined in Kula's IPO prospectus in 2010."

I presume that this would not only affect KGD but also GPR? May depend on how the agreements were structured...

(I hold KGD, not GPR, and rate both a Buy)
