Excelsior Mining Corp. announced additional assay results from the infill drill program on the Johnson Camp mine pits (JCM) located in Cochise County, southeastern Arizona and provide an operations update. Drill Program: Due to successful drilling in the NE corner of Burro pit, additional holes were added and those with assays returned are reported below.

The improved results will allow the Company to develop a mine plan that focusses on this new, higher-grade, mineralized zone. Permitting of the new leach pad to restart operations is in progress, however the additional drilling and metallurgical testing will push the Company's goal of restarting mining operations at JCM into 2023. The drilling program is now completed with a total of 43 diamond holes being drilled.

Six holes are still awaiting assays. Sequential copper assays for the remaining 37 holes have an average leaching potential exceeding 68% (excludes intervals that contain sulfide mineralization).
