Calibre’s 2023 Exploration Drill Program Along the Panteon VTEM Corridor Yields Multiple New Exciting High-Grade Discoveries in Untapped Regions; Additional Drilling Intersects 15.64 g/t Gold over 2.5 metres and 31.30 g/t Gold over 1.4 metres

VANCOUVER, British Columbia, July 18, 2023 (GLOBE NEWSWIRE) -- Calibre Mining Corp. (TSX: CXB; OTCQX: CXBMF) (the "Company" or "Calibre") is pleased to announce positive results from the 2023 expansion drilling at Panteon North and step-out drilling along the Panteon VTEM Gold Corridor within the Limon Mine Complex. These new intercepts continue to demonstrate the potential of the multi-kilometre long structure identified by our 2022 VTEM geophysical survey. Today’s results are located along the west side of the VTEM corridor, proximal to and extending approximately two kilometres from the high-grade Panteon North project.

New drill intercept highlights along the Panteon VTEM Geophysical Gold Corridor include:

  • 15.64 g/t Au over 2.5 metres Estimated True Width (“ETW”) in Hole LIM-23-4765
  • 3.57 g/t Au over 13.4 metres ETW including 7.09 g/t Au over 6.0 metres ETW in Hole LIM-23-4759
  • 19.67 g/t Au over 1.9 metres ETW and 6.87 g/t Au over 7.0 metres including 19.80 g/t Au over 1.1 metres ETW in Hole LIM-23-4752
  • 21.62 g/t Au over 2.0 metres ETW including 31.30 g/t Au 1.4 metres ETW in Hole LIM-23-4743
  • 20.89 g/t Au over 1.3 metres ETW in Hole LIM-23-4745
  • 19.90 g/t Au over 1.2 metres ETW in Hole LIM-23-4758
  • 8.50 g/t Au over 3.1 metres ETW including 21.40 g/t Au over 1.2 metres ETW in Hole LIM-23-4763
  • 24.40 g/t Au over 1.3 metres ETW in Hole LIM-23-4738

March 21, 2023 intercepts along the Panteon VTEM Geophysical Gold Corridor and Panteon North:

  • 17.45 g/t Au over 4.1 metres ETW including 38.45 g/t Au over 1.8 metres ETW in Hole LIM-22-4736;
  • 29.68 g/t Au over 4.3 metres ETW in Hole LIM-22-4724.

Note: Estimated True Widths for reported vein intercepts are based on 3D models of the 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: “Following a successful 2022 drill campaign, I am excited to report the first batch of 2023 high-grade drill results from the multi-kilometre VTEM Gold Corridor located within the Limon Mine Complex which further validate the expansion opportunity. At this stage we have only tested a small portion of the strike extent along the Corridor, yet strong potential exists on both the west and east of the resistivity contact. Given our strong operating cash flow and ability to self-fund growth and exploration we have nine drill rigs active across our near mine and satellite targets in Nicaragua.”

Tom Gallo, Senior Vice President, Growth of Calibre, stated: “I am pleased with the 2023 drill success along the VTEM Gold Corridor. Initial delineation of three main areas outside the known Panteon North Reserve area should have a positive impact on our year end Mineral Resource statement. Field work has identified two areas of interest, located only 3 km north of Panteon, with notable trends of high-grade rock samples at surface. Drilling will commence in these locations in August.

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' 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 gravimetric finish. Analyses for silver and other elements of interest are performed via Induction Coupled Plasma (ICP)
