Calibre announced drill results from its 2024 exploration program within its 250 km2Valentine Gold Mine complex (Valentine) in Newfoundland & Labrador, Canada. These results are located immediately southwest of the Leprechaun deposit, on the edge of the open pit (2022 Mineral Reserves of 15.1Mt grading 1.73 g/t gold containing 0.84 Moz), one of the three open pits at Valentine. Highlights from the Leprechaun Southwest drill program include: 2.25 g/t Au over 15.30 metres Estimated True Width (?ETW?) including 24.68 g/t Au over 0.85 metres ETW in Hole LS-24-002; 1.87 g/t Au over 11.57 metres ETW including 9.26 g/t Au over 0.89 metres in Hole LS-14-007; 36.83 g/t Au over 0.91 metres ETW in Hole LS-24-010; 13.32 g/t Au over 0.85 metres ETW in Hole LS-24-011.

These initial 2024 drill results tested new targets up to hundreds of metres from the high grade ore control RC holes. From that infill program, several high-grade intercepts, including 46.53 g/t over 5.3 metres indicate significant gold mineralization outside of the current Mineral Reserve block model and remain open for expansion. New, near surface, in-pit gold mineralization was discovered, demonstrating upside potential to the 2022 Mineral Resource statement.

Additional zones of mineralization have been identified and remain open along strike and at depth and will be followed up in upcoming drill programs. These results are within the three pit mine plan covering only six kilometres of the under-explored 32 kilometre VLSZ, the main control of gold mineralization at Valentine. QA/QC protocols followed at the Valentine Gold Mine include the insertion of blanks and standards at regular intervals in each sample batch. Drill core is cut in half with one half retained at site, the other half tagged and sent to Eastern Analytical Limited in Springdale, NL.

All reported core samples are analyzed for Au by fire assay (30g) with AA finish. All samples above 0.30 g/t Au in economically interesting intervals are further assayed using metallic screen to mitigate the presence of coarse gold. Significant mineralized intervals are reported as core lengths and estimated true width (40 - 95% of core length), and reported with and without a top-cut of 50 g/t Au applied.
