The Sangihe Project was first discovered and primitively explored in 1986. PT Mears Soputan Mining and their JV partner Muswellbrook worked on the project until 1993. Chip sampling, ground magnetic surveys and IP surveys were conducted, resulting in local prospecting and artisanal mining at the gold and gold-copper anomalies identified. From 1989-1993 a 5,000m drill program was conducted at the Binebase and Bawone prospects. Until 2006, with various local mining entrepreneurs and junior mining companies, further trenching and exploration was conducted.
