Blue Thunder Mining Inc. announced that it has completed its recent diamond- drilling program on its Muus property, part of the Company's 51,000 hectare Muus Gold Project (the "Project"), strategically located in the heart of the Chibougamau Gold District in central Québec. Five holes totalling 1,251 metres were drilled from November 5th to December 3rd, 2022. From this drill core, 447 samples (including 44 QAQC samples) were taken from intervals judged visibly to be mineralized and/or hydrothermally altered.

Assays are pending, with results expected in mid-January 2023. The following summarizes the rationale for and visual observations at each hole. Significant assays will be released when available.

Please refer to the Company's News Release dated November 15, 2022 for additional plans showing target locations. This hole, about 1.5 kilometres east of the Discovery Zone, was drilled to a depth of 246 metres, targeting potential polymetallic volcanogenic massive sulphide mineralization as suggested by anomalous soil geochemistry and a geophysical Induced Polarization (IP) anomaly (coincident chargeability and conductivity). Drilling intercepted a graphitic black shale over 12 metres (from 136 to 148 metres down hole) containing 20% to 40% nodular pyrite, locally remobilized in stringers.

This hole, near the Welb prospect was drilled to a length of 117 metres, targeting gold-bearing quartz veins as observed in a historical trench at the Welb gold showing. Drilling intercepted several smoky quartz veins with 1% to 4% pyrite and pyrrhotite from 17.5 to 22.3m down hole. A second mineralized interval was noted comprising mineralized chert with approximately 4% to 10% of what appears to be pyrrhotite and/or pyrite from 82.0 to 87.4m down hole.

This hole at Lac Bernard was drilled to a length of 555 metres, targeting Nelligan-type metasediment- hosted gold mineralization. The drill target was defined by several IP (conductivity and chargeability) anomalies within a halo of hydrothermal alteration, as interpreted by Faure (2012; projet CONSOREM 2012-02), as well as by previous glacial till sampling which disclosed gold and arsenic anomalies. Several intervals of up to tens of metres of altered and potentially mineralized sericite and carbonate schist were intercepted, displaying varying extents of silica and chlorite alteration with up to 1 % disseminated pyrite.
