PART 2 SUMMARY DESCRIPTION OF BUSINESS

What Is Our Business?

Silver X is a silver producer and developer. Silver X owns the 20,472-hectare Nueva Recuperada Silver Project (the "Project") in Central Peru and produces silver, gold, lead and zinc from the Tangana Mining Unit. Silver X's mission is to be a premier silver company delivering outstanding value to all stakeholders by consolidating and developing undervalued assets, creating value by adding resources and increasing production while aspiring to social and environmental excellence.

The Project lies in the heart of Peru's premier silver-gold-lead-zinc belt. This large geological system encompasses hundreds of epithermal intermediate sulfidation veins containing medium to high-grade of silver rich polymetallic mineralization. The Project was assembled through acquisitions from major silver producers such as Compañía de Minas Buenaventura SAA, Pan American Silver Corporation, Barrick Gold Corporation and Peruvian Metals Corporation, among other companies. The project includes: (i) the Tangana Mining Unit, a precious- and base-metal operation that is in the northern portion of the project comprised of 100-plus veins spanning an area of more than 6,500 hectares, and (ii) the Plata Mining Area advanced Project (formerly referred to as Esperanza), a grouping of historic silver-polymetallic veins, with significant exploration upside in the southern portion of the project comprised of 200-plus veins often with intense anatomizing, spanning an area of more than 7,000 hectares; (iii) and the Red Silver Mining Unit, a high grade silver target in exploration stages and subject to production in the past. As at October 31, 2022, the Nueva Recuperada Project has an estimated 11.89 million tonnes of inferred resources at grades of 152.50 g/t Ag, 0.31 g/t Au, 1.72% Pb, 1.79% Zn and combined Measured and Indicated Mineral Resources of 3.61 million tonnes with grades of 70.82 g/t Ag, 1.47 g/t Au, 1.78% Pb and 1.27% Zn and includes a 720 tonnes per day, fully permitted, fully operational processing facility that started processing mineralization in 2019.

Recent Developments

The following is a brief summary of the recent developments involving or affecting the Issuer.

On March 13, 2025, the Company closed a private placement offering with the placement of 20,588,235 units (the "March 2025 Units") at a price of C$0.17 per March 2025 Unit for gross proceeds of C$3,500,000 (the "March Placement"). Each March 2025 Unit consists of one common share and one share purchase warrant entitling the holder to purchase one share of the Company at a price of C$0.25 per share for a period of 36 months from the date of closing of the March Placement. The Company paid its broker a commission of C$208,980, and other legal fees and disbursements of C$104,252. Furthermore, the Company issued 1,229,294 broker warrants (the "March Broker Warrants"). Each March Broker Warrant shall be exercisable for one Common Share at a price of C$0.17 per Common Share at any time on or before March 13, 2028.

On June 24, 2025, the Company secured a US$2,000,000 prepayment facility (the "Facility") and copper offtake agreement (the "Offtake") for its Nueva Recuperada project with Trafigura PTE Ltd. ("Trafigura"). The US$2,000,000 Facility will be drawn in tranches. The Facility carries an interest rate of SOFR plus 6%, with an expected repayment term of 20 months from the date of initial drawdown. As part of the financing terms, Silver X will issue 2,500,000 warrants, exercisable for a period of up to 25-months at an exercise price representing a 25% premium to the 20-day volume-weighted average price (VWAP) on the TSX-V as of the signing date. Under the terms of the expanded Offtake agreement, Silver X will sell 100% of the copper concentrate produced at the Nueva Recuperada project to Trafigura from the start of copper production through April 2029. This new agreement builds on the existing offtake arrangement for Nueva Recuperada and reflects the continued partnership between the

two companies. Proceeds will be used for the implementation of a third flotation circuit at the Recuperada plant to produce copper concentrates with silver and gold contents, as well as for mine development and working capital.

The above noted allocation of capital and anticipated timing represents the Issuer's current intentions based upon its present plans and business condition, which could change in the future as its plans and business conditions evolve. Although the Issuer intends to expend the proceeds from the Offering and its available funds as set forth above, there may be circumstances where, for sound business reasons, a reallocation of funds may be deemed prudent or necessary and may vary materially from that set forth above, as the amounts actually allocated and spent will depend on a number of factors, including the Issuer's ability to execute on its business plan. See the "Cautionary Note Regarding Forward-Looking Statements" section above.

The most recent audited annual financial statements and interim financial report of the Issuer included a going concern note. The Issuer is focused on mining and further developing its mineral properties in the Nueva Recuperada Silver District in Central Peru and has not yet generated sustained positive cash flows from its operating activities, which may cast doubt on the Issuer's ability to continue as a going concern. The Offering is intended to permit the Issuer to continue to achieve its business objectives and is not expected to affect the decision to include a going concern note in the next annual financial statements of the Issuer
