US geological survey eyes PNG copper and geothermal potential for strategic partnership

The U.S. Geological Survey (USGS) has expressed strong interest in the mineral and geothermal resources of Papua New Guinea, signaling a potential strategic partnership. Teresa Kirschling, Deputy Associate Director for Geology, Energy and Minerals at USGS, confirmed the agency's growing work in the Pacific, including offshore geologic mapping to better understand mineral resources.

“

We do have some work in the Pacific as a part of our minerals portfolio. We are conducting offshore geologic mapping in the Pacific to better understand offshore mineral resources.

Kirschling highlighted PNG's significant critical mineral potential, particularly in copper and geothermal energy. She noted that USGS has restructured to integrate its geologic mapping, energy resources, and mineral resources programs, emphasizing the foundational role of mapping in identifying and developing these resources. The agency's goal is to make maps and methods publicly accessible to guide development efforts.

“

If you think about critical mineral potential, there’s real potential.

Papua New Guinea, home to major mining operations like Newmont's Wafi-Golpu and Lihir, possesses substantial copper reserves crucial for the global energy transition. Kirschling cited Nevada as an example where USGS simultaneously mapped geothermal and critical mineral potential, showcasing the technical synergy between energy and mineral sectors. This integrated approach is seen as key for PNG to diversify its economy beyond raw material exports, as mineral development is intrinsically linked to energy resources.

Making sure that we’re making all of those publicly available, that we’re sharing our methods… we understand the foundational nature of these maps and how those inform resources.
