Sedangkan pada kontrak karya 2008 hingga 2025 yang telah ditandatangani INCO, pembayaran royalti 'flat' dengan asumsi harga 7-8 dolar AS per pound, namun saat ini harga telah mencapai 11 dolar per pound, sehingga minta 'review' besaran royalti ini.
Based on the signed 2008-2025 work contract, however, PT INCO was required to pay royalties at a flat rate based on the assumed nickel price of US$7 - US$8 per pound.
