Calibre Mining Corp. Continues to Intercept High-Grade Gold Mineralization at Its Eastern Borosi Mine Complex
Drilling Intersects Include 13.24 g/t Gold Over 5.8 Metres and 11.62 g/t Gold Over 3.8 MetresVANCOUVER, Aug. 20, 2024 - Calibre Mining Corp. (TSX: CXB; OTCQX: CXBMF) (the "Company" or "Calibre") is pleased to announce drill results from its 2024 resource conversion and expansion program within the Guapinol open pit area on the Company's 176 km2 Eastern Borosi Mine Complex ("Eastern Borosi") in northeastern Nicaragua. This prolific land package sits adjacent to a larger, 100%-owned, 7,281 km2 Atlantic Mineral Concession package which has high potential for the discovery of both epithermal gold-silver and porphyry copper-gold systems.
Gold highlights from the Eastern Borosi drill program
- 13.24 g/t Au over 5.8 metres Estimated True Width ("ETW") including 18.52 g/t Au over 4.0 metres ETW in Hole GP-24-182;
- 9.24 g/t Au over 6.2 metres ETW including 17.45 g/t Au over 3.1 metres ETW in Hole GP-24-189;
- 11.62 g/t Au over 3.8 metres ETW including 22.36 g/t Au over 1.9 metres ETW in Hole GP-24-187;
- 9.25 g/t Au over 1.6 metres EW including 12.70 g/t Au over 1.1 metres ETW in Hole GP-24-179;
- 7.81 g/t Au over 8.6 metres ETW including 16.61 g/t Au over 3.7 metres ETW in Hole GP-24-181;
- 3.37 g/t Au over 2.9 metres ETW including 6.13 g/t Au over 1.4 metres ETW and 3.31 g/t Au over 7.3 metres ETW including 8.15 g/t Au over 1.6 metres ETW and 6.67 g/t Au over 0.8 metres ETW in Hole GP-24-178A; and
- 5.01 g/t Au over 4.5 metres ETW including 8.59 g/t Au over 2.5 metres ETW in Hole GP-24-186.
Note: Estimated True Widths for reported vein intercepts are based on 3D models of individual veins. Estimates are determined in cross-section by measuring the modelled vein thickness perpendicular to the vein margins and through the midpoint of the drill hole intercept. Percentage-based differences between individual ETWs and down-hole interval lengths will vary between drill holes depending on drill hole inclination, variations in vein strike and dip, and overall geometries of the different vein systems.
Darren Hall, President and Chief Executive Officer of Calibre, stated: "Today's drill results from Eastern Borosi confirm that significant high-grade gold mineralization exists outside of the present deposit area surrounding the Guapinol operation, reinforcing the potential for mine life extension. These drill results build upon the high-grade gold mineralization results reported earlier this year (see News Release dated April 15, 2024) confirming the significant mineral endowment of the district as well as the high potential for discovery and resource expansion within the entire 176 km2 Eastern Borosi land package."

Quality Assurance/Quality Control
Calibre maintains a Quality Assurance/Quality Control ("QA/QC") program for all its exploration projects using industry best practices. Key elements of the QA/QC program include verifiable chain of custody for samples, regular insertion of certified reference standards and blanks, and duplicate check assays. Drill core is halved and shipped in sealed bags to Bureau Veritas in Managua, Nicaragua, an independent analytical services provider with global certifications for Quality Management Systems ISO 9001:2008, Environmental Management: ISO14001 and Safety Management OH SAS 18001 and AS4801. Prior to analysis, samples are prepared at Veritas's Managua facility and then shipped to its analytical facility in Vancouver, Canada. Gold analyses are routinely performed via fire assay/AA finish methods. For greater precision of high-grade material, samples assaying 10 g/t Au or higher are re-assayed by fire assay with a gravimetric finish. Analyses for silver and other elements of interest are performed via Induction Coupled Plasma (ICP).
