Well that is an interesting hypothesis but I think it has a few flaws. Now there are certainly wealthy interests in the Philippines who are supportive of the mining industry from the position of providing more wealth for their involvement. But I doubt that they have the sort of expertise that OGC has and can bring to the table. I doubt that OGC would be that keen on the type of arrangement that you are suggesting. It has hung in there at the moment even though it is costing a few million every quarter but whether it would be interested in some sort of sharing arrangement and only getting 40% for all the heavy lifting then I think they could do better elsewhere.
Remember that the two government agencies have recommended that the FTAA be granted. Some influential people need to put a bit of pressure on Duterte or help him to see the advantages of granting the FTAA.
