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.

Selected gold intercepts are depicted in Table 1:

Casa’s extensive database of Congress property information is from several sources, including public archives, records of previous operations and Dubois family records.  Table 2 is a compilation of some of the significant gold intersections from those records.  Data in this news release from earlier sources has not been reviewed or verified by a Qualified Person and should not be relied upon in any evaluation of the Congress Mine.

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.  Vertical sections Figures 2, and 3 illustrate the location of previous drill holes, mine workings and Casa drill holes.

(A complete historic mine plan and sections are posted on the company’s website at )

The Congress gold mine operated at intervals from 1887 to 1992, with reported production of about 400,000 to 500,000 ounces gold by previous operators included Echo Bay Mines Ltd. and Malartic Hygrade.  Casa Minerals Inc. owns ninety percent (90%) interest in the Congress gold mine from 40 feet depth and beyond, subject to a 1.5% Net Smelter Royalty (Arizona, USA).  The property comprises 14 patented mining claims with area 260 acres and undivided one hundred percent of the 494.8 acres that Casa acquired by staking. In a small part of the property, Surface rights to depth 40 feet (9 m) in part of the property are held by a third party. Gold mineralization occurs with vein quartz and in areas of strong siliceous alteration in granite.
