Calibre Mining Corp. (TSX: CXB) (OTCQX: CXBMF) is pleased to announce assay results from its ongoing resource conversion and expansion drill program at the 100% owned Pan Mine (“Pan”), located in the prolific Battle Mountain – Eureka gold trend, Nevada. Numerous results outlined below indicate the potential for resource expansion while focusing on converting known zones of mineralization. During 2022, Calibre is advancing a multi-rig 85,000 metre drill program in Nevada including 50,000 metres focused at Pan.

Highlights from the Pan Resource expansion and discovery drill program include:

Black Stallion Target

• 3.35 g/t Au over 18.3 metres in Hole PR22-087; 0.93 g/t Au over 12.2 metres in Hole PR22-116; 0.82 g/t Au over 10.7 metres in Hole PR22-100; 0.50 g/t Au over 15.2 metres in Hole PR22-083; and
• Significant intercepts outside existing resources remain open to the north, east and west.

Pegasus Target

• 0.53 g/t Au over 27.4 metres in Hole PR22-094; 0.56 g/t Au over 16.8 metres in Hole PR22-082
• 0.80 g/t Au over 47.2 metres in Hole PR22-088; 0.52 g/t Au over 64.0 metres in Hole PR22-093;
• 0.60 g/t Au over 29.6 metres and 0.51 g/t Au over 37.5 metres in Hole PC22-005; and
• Several intercepts extend mineralization down-dip and along strike and are open for further expansion.

Palomino Target

• 1.06 g/t Au over 10.7 metres and 0.96 g/t Au over 10.7 metres in Hole PR22-055.

Dune Target

• 0.90 g/t Au over 22.9 metres in Hole PR22-015; 0.51 g/t Au over 15.2 metres in Hole PR21-062; and
• Near surface mineralization trending and open to the northwest confirming mineralized zones.

Syncline Target

• 1.41 g/t Au over 24.4 metres in Hole PR22-032; and
• Encountered higher grade mineralization to the northwest, outside the Syncline pit and open for expansion.

Dynamite Target

• 0.57 g/t Au over 51.1 metres in Hole PC22-006; 0.53 g/t Au over 22.9 metres in Hole PR22-061;
• 0.54 g/t Au over 15.3 metres in Hole PR22-045; 0.44 g/t Au over 30.5 metres in Hole PR22-077;
• 0.40 g/t Au over 42.7 metres in Hole PR22-073; and
• Mineralization remains open to the east where follow-up drilling is planned.

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: “The recent drilling at Pan has focused on expanding mineralization along trends of known targets. Today’s results confirm our initial interpretation that numerous resource expansion and discovery opportunities exist. We continue to see excellent opportunities for growth and in some cases are seeing shallow, higher grade zones open for further expansion. Since acquiring Fiore Gold in January, 2022 we have announced positive results (see news release dated March 8, 2022 and news release dated April 12, 2022) and anticipate this year’s results will expand resources and lead to additional mine life.”

Quality Assurance/Quality Control

Calibre Mining maintains a Quality Assurance/Quality Control 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. Down hole deviation surveys are provided by International Directional Services, utilizing a surface recording gyroscope, and by trained drill crews operating a north seeking gyroscope supplied by REFLEX. RC drilling was performed by Boart Longyear of Salt Lake City, Utah and 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. An additional cyanide leach assay was also completed. ALS carries ISO/IEC 17025:2017 certification.
