Drilling at Congress Gold Mine Project Returns as high as 14.9 g/t Gold over 1.5m

Vancouver, BC, Feb 1, 2023 - (ACN Newswire) - Casa Minerals Inc. (TSX: CASA) (OTC Pink: CASXF) (FSE: 0CM) (the "Company" or "Casa") is pleased to announce the assay results of the initial exploration at its Congress Gold Mine Project in Yavapai county, Arizona, USA. Casa's work included compilation of historic data and drilling of ten holes with total length 6,828ft HQ Diameter. Results of the field program exceeded expectations, with all the drill holes intersecting the Niagara and Congress Veins extensions on the property and yielded several noteworthy gold intercepts and long intervals of strong gold enrichment.

The highest gold intercepted in phase one, 2022 drilling campaign:
- CCG-004 14.9 g/t over 1.5 meters, as part of a larger intercept of 3.5 g/t over 10.7 meters
- CCG-004 9.3 g/t over 3 meters.

Three distinct areas of gold potential have been identified, two of which were revealed by previous drilling and one is newly discovered, and named for convenience, Congress z1, z2 and z3, respectively. These results demonstrate significant exploration potential of the property.

The following map illustrates the identified and confirmed Congress z1, z2 and z3:

Casa's diamond drilling program tested possible extensions of the formerly-productive Congress and Niagara vein structures and nearby areas. Cores were examined, recorded and sampled with the supervision of personnel from MineMappers, LLC, of Marana, Arizona and Mark Osterberg, ((PhD., P.G., Wisconsin), R.G. (Arizona), RMSME, a qualified registered consulting geologist in the state of Arizona.

Prior to sampling, cores were recorded, photographed and logged for rock types and structures, then halved by sawing: one half was submitted to an independent, ISO 9000 registered commercial analytical laboratory, with initial processing at the lab's Tucson, Arizona, facility and final analysis in Vancouver, Canada. The remaining half-core was retained in a secure storage facility on the property where it is available for further examination. Core handling procedures followed industry-standard QA/QC methods to ensure integrity of analytical data.

Casa's drilling (Figure 1) was directed to southeast parts of the Congress Mine where historic work indicated possible extensions of mined areas and to other areas of potential gold mineralization.
