• Numa Numa Resources Inc. has taken a central role through newly formed agreements that establish a dedicated entity to advance Mainoki’s resource potential.
• One of these entities governs the Mainoki region, a geologically promising area that has drawn interest for its reported mineralization and exploration potential.
• The Mainoki region itself represents one of Bougainville’s most compelling untapped opportunities.

The Mainoki region of Bougainville is emerging as one of the island’s most compelling new frontiers for mineral development, drawing attention for its geological promise at a time when global demand for copper and gold is accelerating (https://ibn.fm/00Osk). With its location inside one of the Pacific’s most resource-rich geological belts, Mainoki is increasingly viewed as a potential contributor to Bougainville’s long-term economic future as the island pursues greater self-determination and responsibly managed growth. With this in mind, Numa Numa Resources, an infrastructure developer and mining investor working closely with Bougainville landowners, has taken a central role through newly formed agreements that establish a dedicated entity to advance Mainoki’s resource potential.

Bougainville’s mining history is both globally significant and central to Papua New Guinea’s broader resource landscape. The island is home to the Panguna Mine, which was once among the largest open-pit copper and gold mining operations in the world. One study estimated the Panguna deposit at roughly 1.8 billion tonnes of ore, containing 5.3 million tonnes of copper and 19.3 million ounces of gold.

Bougainville’s geology is defined by the same tectonic and magmatic forces that created many of the Pacific’s richest mineral belts, placing it within the Papua New Guinea Orogenic Belt, a region known for producing world-class copper, gold and silver deposits. Research shows that this tectonic convergence zone consistently yields porphyry copper systems, epithermal gold deposits and other mineral-rich formations, providing strong geological support for renewed exploration across Bougainville (https://ibn.fm/UIHeT).

As Bougainville moves through a period of political transition following its 2019 independence referendum, its natural resources have become a core pillar of long-term economic planning. The referendum, which recorded a 97.7% vote in favor of independence, demonstrated the population’s desire for political and economic self-determination. Responsible, landowner-led mining is expected to play an essential role in financing future government services, infrastructure and long-term economic stability. The World Bank’s “Papua New Guinea Economic Update” for June 2025 reports that Papua New Guinea’s growth is driven by gold and copper production, and also emphasizes the need for structural reforms and private investment to unlock potential (https://ibn.fm/wuQJQ).

Numa Numa Resources has introduced a development model designed to align with Bougainville’s landowner-centered governance. The company has executed written agreements establishing three new jointly owned entities with landowner groups, each responsible for managing mineral rights and development within its own region under Bougainville’s legal framework. Each entity is structured so that all landowner resource rights are held within the company, jointly managed by Numa Numa and the landowner leadership.

One of these entities governs the Mainoki region, a geologically promising area that has drawn interest for its reported mineralization and exploration potential. This agreement formalizes a structure in which Mainoki landowners retain ownership while benefiting from professional management, infrastructure investment and technical expertise.

The Mainoki region itself represents one of Bougainville’s most compelling untapped opportunities. Situated within the island’s structurally complex mineral belt, the area is believed to contain copper-gold systems consistent with the island’s broader geological profile. Although specific reserve estimates for Mainoki have not yet been publicly detailed, the region’s proximity to known mineralized zones is notable.

Regional studies in Papua New Guinea and the Solomon Islands show that Bougainville lies within a magmatic arc that has generated numerous porphyry copper and epithermal gold systems, many of them related to Miocene–Pliocene volcanic activity (https://ibn.fm/NQE5H). Mainoki’s setting near volcanic and intrusive rock formations is consistent with areas that have historically hosted large-scale copper and gold deposits, and local landowner reports paired with initial fieldwork suggest that the region contains multiple zones of interest for further exploration (https://ibn.fm/4k0de).

As Bougainville seeks pathways for responsible, community-supported resource development, Mainoki is increasingly viewed as a potentially significant contributor capable of supporting new investment, employment and infrastructure advancements. Its development is expected to follow the principles outlined in Bougainville’s Mining Act, which emphasizes landowner consent, environmental stewardship and transparent governance.

Numa Numa’s role in advancing Mainoki is centered on building the early-stage foundation for exploration, infrastructure and development planning. The company’s model is aligned with Bougainville’s emphasis on local participation, ensuring landowners remain direct beneficiaries of resource activity. As the company deepens its work in the region, supported by newly created entities co-owned with landowners, it aims to apply international standards of technical assessment and development planning, helping position Mainoki as a viable future mining district.
