Mr. Jan Alston reports

CMX LIVE INVESTOR WEBINAR PRESENTATION AND Q&A

CMX Gold & Silver Corp. has invited investors and other interested parties to attend the company's upcoming live webinar presentation, audience Q&A (question and answer) and interview.

Chief executive officer Jan Alston and chief financial officer Glen Alston will discuss reactivating Idaho's past-producing Clayton silver mine through modern underground exploration and surface stockpile monetization.

Aspects to discuss

• Premier mining jurisdiction: Idaho ranks No. 7 globally on the Fraser Institute Investment Index, featuring year-round paved access, zero state royalties and no legacy liabilities.
• Focused land position: A total of 1,028 acres covering a mine that historically produced 7.03 Moz (million ounces) silver, 86.7 Mlb (million pounds) lead and 28.1 Mlb zinc.
• Underground upside: High-grade mineralization remains open at depth and along strike, with significant potential for confirming other mineralized veins within the system.
• Stockpile monetization: TOMRA XRT sorting demonstrated a 540-per-cent silver grade upgrade, targeting significant potential cash flow for silver/lead/zinc recoveries and possible gold recoveries as a bonus.
• Exploration road map: Phase 1 budget ($1.35-million (U.S.)) finances 3-D IP/MT geophysics and 2,500 metres of drilling toward a preliminary economic assessment.
• Strong leadership alignment: Management, directors and major investors hold 84 per cent of total shares.

The webinar will be a live, interactive online event where attendees can ask the presenters questions in real time. A recording will be available for those who cannot join the live event.

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.

Commencing Sept. 7, 2026, a comprehensive geophysical program will be conducted over the historic mine and surrounding structures, including a 3-D direct current induced polarization (DCIP) survey and a magnetotelluric (MT) survey. These surveys are intended to delineate known and new vein 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 ore bodies known as the South and North orebodies. 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.
