Here is some background on the Woodlark Islands Gold Project from Kula Gold KGD (a $7M market cap company)
"Background on the Woodlark Island Gold Project, PNG
Kula Gold Limited has advanced its Woodlark Island Gold Project to the point where it is permitted and ready to progress to the next stage. The Project is located 600 kilometres east of Port Moresby in the Milne Bay Province, Papua New Guinea.
Kula’s Joint Venture Partner Geopacific Resources Limited is funding the next $8 million expenditure to advance the gold reserves to a target of 1.2 million ounces of gold to earn additional equity in the Project.
The Project has excellent upside potential through the conversion of Inferred Resources and numerous nearby exploration targets within a short distance of the proposed process plant location.
The Resource Estimates for the Kulumadau and Busai Deposits were re reported and released on 31 January 2017 in accordance with JORC 2012. The estimates for Munasi and Woodlark King have not been re reported in accordance with JORC 2012, as there has been no additional work within these deposits since the previous estimate.
Kula Gold’s Feasibility Study, based on a JORC 2004 Ore Reserve of 766,000 ounces and a gold price of US$1200/ounce, defined a Project with a mine life of nine years, three open pit mining areas and a 1.8Mtpa gravity and carbon in leach plant (KGD ASX release 27 September 2012).
The Company’s 95% owned subsidiary, Woodlark Mining Limited, has been granted the Environment Permit and the Mining Lease for the Project. "

"GPR is continuing its drilling program on Woodlark Island as part of its earn-in obligation under the Farm-in Agreement with Kula Gold. The program aims to upgrade and increase the existing Mineral Resources and boost the Project's Ore Reserves. GPR currently has two diamond drill rigs and one reverse circulation drill rig in operation on the Island. Additional assays from these operations are expected to be received in coming weeks."

could be some useful "loose change" for HIG in due course if it all pans out
