IsoEnergy Ltd.

2024 Work Program

The Company successfully reopened the main decline to the Tony M Mine on July 26, 2024 with initial observations of underground conditions indicating that the main decline and underground equipment shops are in good condition. The Company carried out several initiatives as part of its comprehensive work program at the Tony M Mine in 2024. Main initiatives include carrying out the rehabilitation of the underground, which included scaling, installation of ground support and ventilation systems and engaging with international mining consultants to complete work on the design and implementation of the ventilation plans and ground control plans. Surveys to map the orebody from the underground and surface have been completed. Work also included the preparation of regulatory documents, including updated health and safety plans, ground support plans, ventilation plans and mine rescue plans, along with other relevant materials. The Company also secured and installed new equipment on site.

Three lines of two-dimensional (2D) geophysical surveys were carried out as orientation surveys over the known mineralization at the Tony M Mine. The surveys included electromagnetic (“EM”), Induced Polarization (“IP”), and seismic lines. Multiple anomalies were identified in the surveys as possible mineral pathfinders in the district. To better understand the character of the anomalies, three surface holes were drilled into the survey area. The purpose was to gather petrophysical samples to better calibrate the surface surveys and improve the use of surface geophysics in under explored areas. Uranium mineralization was encountered in all three holes as expected by the current resource model.
