CMX ENGAGES IBN

CMX Gold & Silver Corp. has expanded its marketing investor awareness program to inform potential investors about CMX and its Clayton silver project in Idaho, United States. The company signed a one-year corporate communications agreement with IBN, which was executed on Dec. 31, 2025. The duration of the agreement may be extended by mutual agreement at the end of the term. IBN will operate as an independent contractor to CMX. IBN's base fee under the agreement is $3,000 (U.S.) per month for a one-year total of $36,000 (U.S.). Depending on the scope and type of solutions provided by IBN, additional fees may be adjusted for supplementary bolt-on solutions.

The Clayton silver property

The Clayton silver project is CMX's 100-per-cent-owned flagship asset, located in the Bayhorse mining district of central Idaho, approximately 30 to 40 kilometres south-southwest of Challis. The property comprises a 1,028-acre land package, including 29 patented mining claims and two patented mill sites (approximately 562 acres) and 20 unpatented claims (approximately 466 acres). The patented claims provide surface ownership rights, carry no government royalties and do not require drilling permits.

Beginning in spring 2026, CMX plans to conduct a comprehensive geophysical program over the historic mine and surrounding structures, including a 3-D direct current induced polarization survey and a magnetotelluric survey. These surveys are intended to delineate known structures, identify extensions of partially mined orebodies and evaluate deeper sources of mineralization, with follow-up diamond drilling planned to test priority targets.

The Clayton silver mine operated from 1935 to 1986, and was one of the most active underground mines in the district. Recorded production totalled approximately 7.0 million ounces of silver, along with lead, zinc, copper and minor gold, from an estimated 2.15 million tonnes of ore. Underground development reached eight levels to 1,100 feet, with nearly 19,700 feet of workings, and partially mined two tabular orebodies known as the South and North orebodies (Bob Hillman, MS thesis, June 26, 1986, Eastern Washington University). Mine records and historical drilling indicate that mineralization remains open to depth and along strike. Notably, drill hole 1501-A intersected 22 feet of high-grade polymetallic mineralization at approximately 1,425 feet, confirming continuity below the deepest historic workings. CMX has determined that little modern geophysical work or systematic exploration drilling was conducted during the mine's operating life.
