Upper Kobuk Mineral Projects ("UKMP")Activities

In July, Ambler Metals LLC ("Ambler Metals") used the camp to support a small team of geologists who were continuing work started in 2022 on the stratigraphy and alteration of the Arctic deposit. The focus of the work was to relog existing drill core from 13 holes across the deposit and 4 holes from regional prospects. In addition, sampling was undertaken for chemostratigraphy and alteration footprint definition. Geological and talc models for the Arctic deposit were updated and an updated geological and structural model for the area surrounding Arctic was commenced.

The camp was also utilized by Ambler Metals to conduct sampling of core from the Bornite deposit to be used in a study initiated by the Center to Advance the Science of Exploration to Reclamation in Mining ("CASERM") at the Colorado School of Mines to investigate the occurrence and distribution of critical elements, including germanium. Ambler Metals has recently accepted a proposal from CASERM with leveraged funding from the United States Geological Survey to contribute samples from Bornite to further investigate the occurrence, distribution, and sequestration of critical elements, including germanium.

Ambler Metals has engaged Wood Canada Limited and SRK Consulting (Canada) Inc. to complete an initial scoping level study on the Bornite deposit to determine if the ore at Bornite may extend the mine life at the proposed Arctic Project. The scope of work covers mining, processing, hydrogeology, infrastructure, tailings management, and waste rock management.
