Calibre Mining Corp. (TSX: CXB) (OTCQX: CXBMF) is pleased to announce additional near surface, resource expansion drill results from its 2023 program at the Pan Gold Mine, located on the prolific Battle Mountain – Eureka gold trend in Nevada. Results at the Dynamite North and Palomino targets located immediately north and south of the current open pit operation, respectively, continue to expand zones with grades higher than Pan’s stated Mineral Resource grade of 0.4 g/t gold. These additional higher-grade results, in combination with the newly discovered Coyote target announced earlier this year, located south of the operation, continue to demonstrate the potential to increase resources, grade, and confidence around the Pan mine.

Highlights from the Palomino and Dynamite targets include:

Palomino Target

• 1.23 g/t Au over 38.1 metres including 2.97 g/t Au over 12.2 metres in Hole PR23-080;
• 0.87 g/t Au over 16.8 metres and 1.58 g/t Au over 21.3 metres including 2.56 g/t Au over 10.7 metres in Hole PR23-088;
• 1.13 g/t Au over 22.9 metres including 2.82 g/t Au over 4.6 metres in Hole PR23-056;
• 0.89 g/t Au over 54.9 metres including 1.17 g/t Au over 4.6 metres, 1.41 g/t Au over 9.1 metres and 1.19 g/t Au over 10.7 metres in Hole PR23-066;
• 1.26 g/t Au over 13.7 metres including 1.72 g/t Au over 9.1 metres and 1.07 g/t Au over 10.7 metres including 1.75 g/t Au over 4.6 metres in Hole PR23-076; and
• 0.59 g/t Au over 32.0 metres in Hole PR23-086.

Dynamite North Target

• 0.70 g/t Au over 18.3 metres and 0.79 g/t Au over 32 metres including 2.31 g/t Au over 6.1 metres and 1.21 g/t Au over 3.1 metres in Hole PR23-047;
• 0.54 g/t Au over 27.4 metres in Hole PR23-049; and
• 0.50 g/t Au over 91.4 metres in Hole PR23-050.

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 highly encouraging drill results expand upon our Palomino target results announced on June 21, 2023, and immediately surround the current open pit operations. We look forward to additional results as we continue to advance our discovery and resource expansion drill programs across the operation and mineral concessions where we have identified numerous highly prospective targets.”

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. All assay batches passed QAQC. Collar surveys are conducted by a mine surveyor using a Trimble instrument. Down hole deviation surveys are provided by trained drill crews operating a north-seeking gyroscope supplied by REFLEX. Collar and downhole surveys are verified by Calibre geologists. RC drilling was performed by Alford Drilling from Elko, Nevada. Assays were performed by Bureau Veritas, Reno where fire assays were determined on a 30-gram charge with an AAS finish. Cyanide leach assays were also completed Bureau Veritas carries ISO/IEC 17025:2017 certification.
