Calibre Reports Robust Drill Results at its 100% Owned Golden Eagle Project, USA

Initial drill results from the Golden Eagle program include:

• 30 g/t Au over 92.42 metres including 7.80 g/t Au over 17.3 metres in Hole GEC22-001
• 90 g/t Au over 195.1 metres in Hole GEC22-003
• 38 g/t Au over 114.3 metres; 2.66 g/t Au over 19.8 metres and 2.65 g/t Au over 25.7 metres in Hole GEC22-006

Note: All holes were drilled at angles of -45 to -90 degrees at azimuths designed to intersect targeted structures as nearly as possible to perpendicular when possible. Some drill holes and intercepts reported here did not cross mineralization perpendicularly, and do not represent exact ‘true widths.

Darren Hall, President, and Chief Executive Officer of Calibre stated: “Today’s results from Golden Eagle reinforce the potential for this project to provide significant value to Calibre shareholders. The first phase of this drill program confirms a robust mineral system with consistent gold grades over broad widths. The Golden Eagle Project is a key asset within our United States operating platform which includes the Pan mine and the Gold Rock and Illipah projects in Nevada. I look forward to results from the second phase of drilling as well as the commencement of a comprehensive metallurgical program to fully assess this strategic assets’ potential. Golden Eagle is a meaningful contributor to the Company’s overall mineral resource estimate with 2.0 million ounces in Measured and Indicated Mineral Resource, adding positively to our organic growth strategy.”

About Golden Eagle

The Golden Eagle Mineral Resource estimate, based on a drill hole dataset of 202 holes totalling 38,208 metres at a base cut off grade of 0.48 g/t gold and a gold price of US$1,500 supports a pit constrained Measured & Indicated Resource of 2.02 million ounces at 1.382 g/t and an Inferred Resource of 154,650 ounces at 0.896 g/t (see Fiore Gold’s MRE NI 32-101 Technical Report dated September 24, 2021). The Golden Eagle deposit is characterized as a low-sulphidation epithermal hot springs related deposit. A major part of the deposit is a large body of silicified hydrothermal breccia, but high-grade gold- and silver-rich quartz veins are present in and near the area of hydrothermal breccia. The deposit has as strike length of approximately 750 metres, variable width up to approximately 300 metres and depth of approximately 600 metres. Mineralization occurs at surface on the west and southwest areas of the deposit.

History of the Region

Golden Eagle is located in the northwestern portion of the very productive Republic/Eureka district and includes the former Mountain Lion Mine which was active from 1898 to 1947. The Republic/Eureka Mining District has produced nearly 4 million ounces of gold at an average grade of 19.89 g/t gold over the last 130 years, principally from high grade underground narrow vein deposits. The last operating gold mine in the district was Kinross’ Buckhorn/Kettle River operation which closed in 2017.

Quality Assurance/Quality Control

Calibre Mining 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 the insertion of assay standards, blanks, and duplicates in the sample stream to ensure the assay lab results are within specified performance levels. Downhole deviation, utilizing a surface recording gyroscope, and trained drill crews operating a north-seeking gyroscope supplied by International Directional Services. HQ Core drilling was performed by, Alford Drilling from Elko, Nevada. Assays were performed by ALS, Reno where fire assays were determined on a 30-gram charge with an AAS finish. ALS carries ISO/IEC 17025:2017 certification.

Forward-looking statements in this news release include, but are not limited to: the Company’s expectations toward higher grades mined and processed going forward; statements relating to the Company’s 2022 priority resource expansion opportunities;  the Company’s metal price and cut-off grade assumptions; the Company’s plans for the Pan Mine for 2022, including production and exploration and its contribution to production growth.  Forward-looking statements necessarily involve assumptions, risks and uncertainties, certain of which are beyond Calibre’s control.  For a listing of risk factors applicable to the Company, please refer to Calibre’s annual information form (“AIF”) for the year ended December 31, 2020, and its management discussion and analysis (“MD&A”) for the year ended December 31, 2021, all available on the Company’s SEDAR profile at www.sedar.com.
