Executive Summary

The Bornite Project is currently classified as an early exploration project located in Northern Alaska. As of the reporting period, the process design remains conceptual and is based on limited metallurgical test work results. Despite the early stage, the project has demonstrated a positive response to traditional process test work, suggesting that a conventional processing flowsheet is feasible for future development.

The proposed processing design includes a series of key unit operations aimed at recovering copper from the ore. The flowsheet begins with primary crushing, followed by SAG milling and ball milling to achieve a particle size of approximately 100 microns. Subsequent steps involve rougher copper flotation, re-grinding of the rough concentrate to 10 to 20 microns, and flotation cleaning to produce final copper concentrates. The process concludes with concentrate de-watering and the deposition of tailings solids.

It is noted that while copper recovery test work is detailed in the report, no work has been completed to evaluate the potential recovery of cobalt. The technical report references a proposed flowsheet in Figure 13-2 and Section 13 for detailed recovery results. The project remains in the exploration phase with no defined mine life, throughput, or annual production data at this time.

Executive Summary

The Bornite Project is currently classified as an early exploration project, with process design remaining conceptually based on limited metallurgical test work results. Despite the preliminary nature of the data, the project has demonstrated a positive response to traditional process test work, indicating that a conventional process design is expected for the project. This design encompasses a series of key unit operations aimed at recovering copper from the ore body.

The proposed recovery flowsheet includes primary crushing, followed by SAG and ball milling to approximately 100 microns. The process continues with rougher copper flotation, rough concentrate re-grinding to 10 to 20 microns, and flotation cleaning to produce final copper concentrates. The final stages involve concentrate de-watering and tailings deposition of tailings solids. No work has been completed to evaluate the potential recovery of cobalt.
