Calibre Expands Mineralization to Surface at Frank Zone, Up-Plunge of 2024 Results at the Valentine Gold Mine, Newfoundland & Labrador, Canada; Drilling Intercepts Include 3.08 g/t Gold over 48.2 Metres, 1.62 g/t Gold over 44.6 metres, 1.94 g/t Gold over 36.4 Metres and 3.47 g/t Gold over 12.6 metres; New Discovery Frank Zone Now Traced Over 1 Kilometre Along Strike and 500 Metres Deep 

VANCOUVER, British Columbia, Feb. 11, 2025 (GLOBE NEWSWIRE) -- Calibre Mining Corp. (TSX: CXB; OTCQX: CXBMF) (the "Company" or "Calibre") is pleased to announce additional discovery diamond drill results from its expanded 100,000 metre drill program at the Valentine Gold Mine (“Valentine”) located in Newfoundland & Labrador, Canada. Previous drilling (see news release dated November 25, 2024) highlights the considerable prospectivity to the southwest of the Leprechaun Pit at the Frank Zone. New drill results reveal shallow, broad zones of continuous mineralization, expanding the volume of high-grade gold intercepts to surface. These results align with previously released high-grade trenching and grab sample data. All results discussed in this release are well outside of known mineral resources. Highlights from today’s release include:

• 3.08 g/t Au over 48.2 metres Estimated True Width (“ETW”) in Hole FZ-24-062;
• At surface, 97.87 g/t Au over 3.9 metres ETW and 1.62 g/t Au over 44.6 metres ETW including 2.58 g/t Au over 22.8 metres ETW and 10.11 g/t Au over 0.9 metres ETW in Hole FZ-24-064;
• 1.94 g/t Au over 36.4 metres ETW and 1.25 g/t Au over 19.1 metres ETW in Hole FZ-24-066;
• 1.00 g/t Au over 56.1 metres ETW including 12.67 g/t Au over 0.9 metres ETW in Hole FZ-24-050;
• 0.87 g/t Au over 78.3 metres ETW in hole FZ-24-055; and
• 2.87 g/t Au over 5.4 metres ETW including 11.09 g/t Au over 0.9 metres ETW and 1.28 g/t Au over 20.7 metres ETW and 3.47 g/t Au over 12.6 metres ETW including 31.37 g/t Au over 0.9 metres ETW in Hole FZ-24-047.

Darren Hall, President and Chief Executive Officer of Calibre, stated: “Follow-up discovery drilling at the Frank Zone, located one kilometre southwest of reported Mineral Resources, continues to return broad intervals of gold mineralization. Importantly, drilling has now traced mineralization to surface, highlighting the potential for another open pit. These new intercepts geologically align with ore from the Marathon, Berry and Leprechaun open pits. While exploration of the Frank Zone is still in its early stages, current data indicates that the zone remains open to the southwest and to the north and has now been traced for over one kilometre along strike and to a depth of approximately 500 metres. Historically, drilling at Valentine has mainly focused on the 8-kilometre stretch from Leprechaun to Marathon Pit, along the Valentine Lake Shear Zone. This 32 km long structure remains highly prospective for discovering additional gold resources and represents only a small fraction of the broader 250 km² land package. With construction progressing on plan, Valentine remains on schedule to achieve first gold in Q2 of this year, positioning Calibre into a mid-tier gold producer with annual production of 450,000 to 500,000 ounces.”

Quality Assurance/Quality Control
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 and those in economically interesting intervals are further assayed using metallic screen to mitigate the presence of coarse gold. Significant mineralized intervals are reported in Table 1 as core lengths and estimated true width (80 - 100% of core length).
