Calibre Outlines Multi-Rig Exploration Programs and Key 2022 Objectives for Resource and Producton Growth in Nicaragua




Calibre Mining Corp. (TSX: CXB; OTCQX: CXBMF) (the \”Company\” or \”Calibre\”) is pleased to provide an update in respect of the Company\-s 2022 discovery and resource expansion drilling programs at Limon, Libertad, Pavon and Eastern Borosi in Nicaragua, highlighting results from 2021 and outlining key 2022 targets and objectives.

2021 Exploration Highlights and 2022 Key Objectives

Year end 2020 reserves increased 200% to 864,000 ounces grading 4.49 g/t gold after depletion1;

Completed in excess of 100 km of drilling with the objective of putting five years of mine life into Reserves (End of Year 2021 Resource and Reserve update planned for end of Q1 2022);

2022 programs have been designed to target >250,000-ounce deposits to help bolster the Company�s project pipelines, providing a solid base for future growth;

Infill drilling to advance technical studies at the Eastern Borosi Project (“EBP”) including Riscos de Oro underground and Guapinol/Vancouver open pit mines;

Approved a US$22 million exploration budget for 2022 including 85 km of drilling focused on resource expansion and discovery with nine drill rigs currently operating across the assets;

High-grade, resource expansion opportunities at Volcan, Tranca, Panteon Northeast, Talavera extension and Southwest Riscos De Oro which are not yet included in the Company�s Resources;

Advanced the newly approved Buena Vista concession, located near the Limon mine complex where at least seven new vein targets have been identified and the La Fortuna concession, located near the Libertad mine complex which covers a large, newly discovered epithermal alteration zone exposed at surface over 8 km2, drilling to commence in late 2022;

Initiated 10,000-line km of airborne geophysical surveys (VTEM and EM) to help define and vector new targets, and;

Exploration over the last two years has positioned Calibre for 2023 and 2024 production growth.

Darren Hall, President & Chief Executive Officer of Calibre, stated: “During 2021 our primary exploration efforts focused on increasing confidence in known resource areas at Limon, Libertad, Pavon and EBP which I expect will positively impact reserves after 2021 depletion and further increase confidence in future production. Additionally the team advanced new prospective concessions along the western epithermal belt, discovered new zones, progressed our geological understanding and target delineation work which form the basis of our 2022 drilling programs.

As a result of the exploration work completed over the last two years, we are in a strong position for 2023 and 2024 production growth. The discovery of new gold zones and continued progress at the high-grade EBP strengthens our outlook to continually expand resources and reserves. Our initial focus at EBP has been to progress the Guapinol, Vancouver and Riscos De Oro deposits which continues with permitting, studies and consultation followed by a construction decision in the first half of 2023. We continue to discover and develop new ore bodies through a sustained commitment to exploration, thereby unlocking the growth and discovery opportunities we see across our portfolio of mines and exploration properties.”

Tom Gallo, Calibre\-s newly appointed SVP Growth, comments: “I left Canaccord Genuity as a mining analyst and joined Calibre because I believed in the considerable geological potential of Nicaragua. Having spent time in country, I am impressed with the team\-s focus over the past two years in converting resources to reserves, but I am extremely encouraged by the untapped resource growth potential on our concessions. What we are targeting in 2022 far exceeded my expectations when I joined, and I am confident we will be successful in adding material new ounces into our project pipeline going forward.”

Libertad Mine Complex

Libertad and surrounding concessions consist of several low sulphidation epithermal vein systems with historic production of >1.9 Mozs of gold. End of year 2020 reserves include 296 koz (1.95 Mt grading 4.71 g/t gold with active operations at Jabali underground and Pavon Norte open pit) (See March 29, 2021 news release). Exploration work has demonstrated potential in several areas for near-surface mineralization, resource growth and new high priority discoveries and targets within 5-10 km of the Libertad mill and surrounding concessions. Drilling is underway with three rigs on priority targets, details include:

During 2021 the Company significantly advanced three of six known resource zones including Guapinol/Vancouver and Riscos De Oro with technical studies, environmental baseline work, community consultations, geotechnical, metallurgical and infill drilling. Calibre completed these programs and has submitted permit applications to advance the asset expected to provide high-grade mill feed to the Libertad mill during the second half of 2023.

Reinterpretations of historic surface and downhole drill data3 has significantly advanced the exploration pipeline at EBP. Concurrent target delineation and exploration drill programs have been ongoing and have restarted with two rigs testing extensions to existing resources and newly identified targets including:

Resource Growth Opportunities

During 2021 Calibre initiated mining at Pavon Norte the first of three known open pit gold deposits. End of year reserves include 200 koz at 4.86 g/t gold (see March 29, 2021 news release). Calibre is advancing development and permitting along trend to begin mining at Pavon Central by 2023 which hosts an average reserve grade of 6.9 g/t Au, significantly higher grade than Pavon Norte, and is expected to contribute to 2023 and 2024 production growth. At Pavon, Calibre has two rigs drilling along strike of Pavon Central and South and parallel vein structures to the South.

New Buena Vista Concession

The Buena Vista project is located approximately 20 km east of the Limon Mine complex and 10 km northwest of the La India mine along the same structural trend which controls the gold mineralization at La India. Surface mapping and sampling at Buena Vista have identified at least seven vein target areas. Individual targets within the concession host gold bearing breccia and quartz veins with semi-continuous strike lengths up to 3 km long. Outcrop sampling of the veins have returned values from <0.1 g/t to 8.3 g/t in rock chip samples. The 2022 program will focus on further definition and extension of currently identified vein structures with mapping, rock chip sampling and soil sampling to define and prioritize drill targets. Permit applications have been submitted and drilling and trenching activities are expected to begin in Q4 of 2022 or early 2023. An electromagnetic (VTEM) airborne geophysical survey is planned for Q1 2022 and will assist in drill target definition in combination with mapping and geochemical sampling. New La Fortuna Concession The Fortuna concession is located approximately 35 km south of the Libertad Mine complex and covers a large epithermal alteration zone which is exposed at surface over 8 km2. Alteration identified in the area is dominated by strong silicification and argillic alteration with characteristics of high-sulfidation and low-sulfidation style gold targets in different portions of the concession. Drill permit applications have been submitted and initial surface work was completed in 2021 and will continue in 2022. Link – 2022 Target Figures

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 Plasmaspectrometry (\”ICP\”).
