MINING AND PROCESSING
The mining method used for the FS is Long Hole Open Stoping (LHOS) method with ribs and sill pillars to consistently sustain the production and mill throughput design rate. Required infrastructure to support the mine operation have been included in the design, including materials handling equipment. Trucking and mobile equipment have been optimized in the mine design along with implementation of conveyors for both crushed ore and waste.
Underground mobile crushers are utilized followed by a grinding circuit including a semi-autogenous grinding (SAG) mill and a ball mill located on surface prior to flotation. The flotation concentrate is filtered using a plate and frame pressure filter and stored in a storage warehouse prior to shipping through the existing and operational port and ship loaders. The mine and process facility will be powered by an existing 132 kV power line. Fresh water requirements for the process plant and the mine will be provided from an existing water dam using an existing buried pipeline. A water treatment plant has been included to treat the underground mine water to a quality suitable for reuse within the processing plant, thereby reducing demand for freshwater abstraction from the water reservoir and to treat the excess mine water to a quality suitable for controlled discharge during upset conditions (e.g. processing plant shutdowns or maintenance), in accordance with applicable Norwegian and EU environmental standards.

ECONOMIC IMPACT
The Company expects the Project to generate significant economic benefits at both the local and national levels. At peak construction, the Company expects to employ, directly or indirectly, approximately 200 personnel, and approximately 100 personnel during commercial production operations, with indirect employment estimated at two to three times these levels through supporting industries and services.
The Company is implementing strategies to maximize the number of long-term employees residing locally, which is expected to provide a sustained boost to the regional economy and support the creation of additional long-term indirect employment associated with population growth.
Based on the assumptions used in the Feasibility Study and applying current Norwegian fiscal regimes, the Project is expected to generate substantial government revenues over its life. Using long-term consensus commodity prices, life-of-mine Norwegian government royalties are estimated at approximately
At spot commodity prices, life-of-mine Norwegian government royalties are estimated at approximately
Opportunity Case
The FS reserve estimate excludes inferred material from the resource estimate. The potential conversion of this inferred material supports the opportunity case and showcases the potential of the life of mine extension to 17 years, considering the same production throughput.

CAUTIONARY STATEMENT REGARDING ESTIMATES OF MINERAL RESOURCES
This news release uses the terms measured, indicated and inferred Mineral Resources as a relative measure of the level of confidence in the Mineral Resource estimate. Readers are cautioned that Mineral Resources are not Mineral Reserves and that the economic viability of resources that are not Mineral Reserves has not been demonstrated. The Mineral Resource estimate referenced in the Technical Report and summarized in this news release may be materially affected by geology, environmental, permitting, legal, title, socio-political, marketing or other relevant issues. Mineral Resources in the Technical Report are reported using the 2014 CIM Definition Standards and were estimated in accordance with the CIM 2019 Best Practices Guidelines, as required by NI 43-101. Under NI 43-101, estimates of inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies or economic studies except for preliminary economic assessments. Readers are cautioned not to assume that further work on the stated Mineral Resources will lead to Mineral Reserves that can be mined economically.
