CASCADA SILVER CORP. TO BECOME ATERRA METALS INC

Cascada Silver Corp. has changed its name to Aterra Metals Inc. to better reflect the company's focus on copper and gold exploration and development. Cascada recently announced its intention to acquire three advanced copper-gold porphyry properties in Chile and final binding option agreements on each of the properties are being finalized.

The common shares of the company will commence trading with the name Aterra Metals under the trading symbol ATC at the beginning of trading on Dec. 16, 2025. The board of directors passed a resolution approving the name change in accordance with the articles of the company. The OTCQB symbol will be updated in due course.

Commenting on the new name, Carl Hansen, chief executive officer, noted: "The name Aterra Metals is inspired by the potential of Atacama's mineral-rich terrain. It reflects management's exceptional discovery record in Chile's Atacama region -- one of the world's most productive mining areas. For more than three decades, our team has consistently demonstrated a proven ability to identify and advance high-value mineral deposits. This experience and sustained success underpins our strategy for generating meaningful shareholder value as we finalize the recently announced acquisitions of three advanced-stage copper-gold properties."

On Nov. 20, 2025, Cascada announced that it had signed memoranda of understanding to acquire three advanced copper-gold porphyry properties in Region III, Chile, approximately 60 kilometres south of Vallenar. The properties have been subject to significant historical exploration activities, including drilling and, in the case of the Frontera property, preparation of a historical resource estimate. Highlights from the properties included:

• Frontera property deposit historical mineral resource estimate:
  • 16 million tonnes (t) indicated grading 0.66 per cent copper equivalent (CuEq) (0.38 per cent copper (Cu) and 0.22 gram per tonne (g/t) gold (Au));
  • 34 million t inferred grading 0.64 per cent CuEq (0.36 per cent Cu and 0.22 g/t Au);
• Taruca property (Totora target) historical drilling highlights include:
  • 142 metres (m) grading 0.69 per cent CuEq (0.47 per cent Cu and 0.17 g/t Au), hole DDHTP-02;
  • 114 m grading 0.61 per cent CuEq (0.23 per cent Cu and 0.31 g/t Au), hole DDHTO-07;
• Clinton property historical drilling highlights include:
  • 166 m grading 0.62 per cent CuEq (0.23 per cent Cu and 0.31 g/t Au), hole RCCL-01;
  • 278 m grading 0.61 per cent CuEq (0.23 per cent Cu and 0.30 g/t Au), hole DDHCL-06.

Copper equivalent calculation: CuEq grades were calculated using a copper price of $4 per pound and a gold price of $3,500 per ounce ($112.53 per gram). CuEq grades are calculated as follows: CuEq equals (((Au grade times 112.53) divided by 4.00 divided by 2,204.6)) times 100 plus Cu grade. No recovery factors are used in this calculation. Metal prices are in U.S. dollars.

Note that Cascada has not undertaken any independent investigation of the historical results from the properties, nor has it verified the underlying technical basis for the historical mineral resource and drill results. The reader is cautioned against relying on the accuracy or reliability of the historical results presented; however, Cascada considers historical results relevant as those results will be used as a guide to plan future exploration programs. The company considers the data to be reliable for those purposes only and not indicative of the nature of any actual mineral resource.

The Frontera property historical resource was prepared by Hot Chile Ltd. under Australasian Code for Reporting on Exploration Results, Mineral Resources and Ore Reserves (The JORC Code, 2012 Edition), and published on March 11, 2014. The mineral estimate was based upon a cut-off grade of 0.25 per cent Cu. A qualified person, as such term is defined in National Instrument 43-101, Standards of Disclosure for Mineral Projects, of the Canadian Securities Administrators, has not undertaken sufficient work to classify the foregoing historical estimate as a current mineral resource and Cascada is not treating the historical estimate as a current mineral resource.
