CMX Gold & Silver Corp. Advances Plan to Assess Underground Resource and Process Stockpile at Clayton Silver Mine

CMX Gold & Silver Corp. (CSE: CXC) (OTC: CXXMF) is moving forward with a plan to assess the underground resource and exploit an above-ground stockpile at its Clayton Silver Project in Idaho, a historic mine that produced silver, zinc, copper, lead, and gold between 1935 and 1986. The company intends to install an ore-sorting system on site to process the stockpile, which potentially holds 1,000,000 tons or more of mineralized material that was left unprocessed due to low grades at the time.

The Clayton ore bodies were never fully mined due to the small scale of historical operations, leaving significant exploitation potential both in the ground and in the stockpile. CMX is implementing a work program that includes site preparation, geophysical survey, drilling, and staking to assess the full potential of the underground resource. The company holds a 100% interest in the property through its wholly owned U.S. subsidiary.

The timing of the development aligns with a growing silver demand-supply deficit. According to the Silver Institute’s World Silver Survey 2026 (https://ibn.fm/iO2ky), global silver demand reached 1.13 billion ounces in 2025, against a documented supply of 1.09 billion ounces, with mine production accounting for 846.6 million ounces. The deficit is projected to grow, representing an opportunity that CMX intends to exploit.

Discovered in the late 1800s, the Clayton Silver Mine was operational from 1935 until 1986, when low prices forced closure. During that period, an estimated 2,145,652 tons of ore were mined and processed. The current stockpile, consisting of material considered too low grade at the time, may contain valuable mineralization that modern ore-sorting technology can economically process.

CMX's strategy involves on-site processing to reduce transportation costs and environmental impact. The ore-sorting system will upgrade the stockpile material before further processing, potentially improving project economics. The underground assessment program aims to define additional resources that could extend the mine life.

Silver has a wide range of industrial and non-industrial applications, including electronics, water purifiers, photovoltaics, jewelry, and silverware. This diversity of use cases underpins the strong demand, with the supply deficit expected to widen as industrial demand grows. CMX's Clayton Project could contribute to bridging this gap.
