The Transaction represents a unique opportunity to significantly enhance our portfolio of operations - it is highly accretive on all key metrics and the transaction structure allows the Company to finance the majority of the acquisition via the cash flow generated by these Assets." Mr. Prestamo continued; "Santacruz shareholders will participate in a larger, more diverse silver producer with strong production growth and enhanced cash flow profile. We look forward to operating in Bolivia and partnering with COMIBOL to generate value for all stakeholders."

Historical Resource Estimates - Bolivar, Porco and Caballo Blanco

Glencore reports resources and reserves in accordance with the 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (JORC Code), the 2016 edition of the South African Code for Reporting of Mineral Resources and Mineral Reserves (SAMREC) and the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Reserves (2014 edition). The term 'Ore Reserves', as defined in Clause 28 of the JORC Code, has the same meaning as 'Mineral Reserves' as defined in the CIM Definition Standards for Mineral Resources and Mineral Reserves. All tonnage information has been rounded to reflect the relative uncertainty in the estimates; there may therefore be small differences in the totals. The Measured and Indicated resources are reported inclusive of those resources modified to produce reserves, unless otherwise noted. Commodity prices and exchange rates used to establish the economic viability of reserves are based on long-term forecasts applied at the time the reserve was estimated.

Glencore's Resources & Reserves report as at December 31, 2020 disclosed Bolivar, Porco and Caballo Blanco mineral resource statements as well as mineral reserve estimates as of December 31, 2020, which remain current for Glencore as of the date hereof. In accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"), the Bolivar, Porco and Caballo Blanco historical mineral resource and mineral reserve estimates use the terms "mineral resource", "inferred mineral resource", "indicated mineral resource" and "measured mineral resource" along with "probable reserve" and "proven reserve" having the same meanings ascribed to those terms by the Canadian Institute of Mining, Metallurgy and Petroleum, as the CIM Definition Standards on Mineral Resources and Mineral Reserves adopted by CIM Council, as amended. As the mineral resource and mineral reserve estimates pre-date Santacruz's agreement to acquire the Assets, Santacruz is treating them as "historical estimates" under NI 43-101, but they remain relevant as the most recent mineral resource and reserves estimates for Bolivar, Porco and Caballo Blanco. Further drilling and resource modelling would be required to upgrade or verify these historical estimates as current mineral resources or reserves for the respective assets and accordingly, they should be relied upon only as a historical resource and reserve estimate of Glencore, which pre-dates Santacruz's agreement to acquire the Assets. A Santacruz "Qualified Person" under NI 43-101 has not done sufficient work to classify the historical estimate as current Mineral Resources or Mineral Reserves and Santacruz is not treating the historical estimate as current Mineral Resources or Mineral Reserves. The Company has engaged JDS Energy & Mining Inc. ("JDS") to validate and verify the historical resources. JDS completed its site visits in August 2021.

The Company has retained Mr. Garth Kirkham, P.Geo., who is a Qualified Person as defined by NI 43-101, to review the disclosure of the Company's historical mineral resources and reserves. Mr. Kirkham is an employee of Kirkham Geosystems Ltd. and is independent of the Company under NI 43-101.

Transaction Summary

Pursuant to the Agreement, Santacruz will acquire all of Glencore's properties, assets and businesses related to the Assets by acquiring various Glencore subsidiaries. The consideration for the Transaction will be payable through upfront consideration of US$20 million in cash on closing (subject to customary working capital adjustments) (the "Closing Cash Payment"), and deferred consideration of US$90 million secured against the Assets. The deferred consideration consists of cash payments of US$22.5 million payable on each anniversary of the closing date for four years and is subject to certain accelerated payment features based on cash flows and silver and zinc prices (the "Deferred Consideration Amount"). Glencore will also retain a 1.5% net smelter returns royalty on the Assets (the "Royalty") and will have a right to acquire 100% of the offtake from the Assets on market terms to be set forth in definitive agreements to be entered into at closing.

The closing of the Transaction is subject to a number of closing conditions, which include, but are not limited to:

• the entering into of certain definitive agreements with Glencore with respect to the Deferred Consideration Amount, the Royalty and certain offtake rights in favour of Glencore;
• obtaining approval from the TSX Venture Exchange (the "TSXV"); and
• customary closing conditions set forth in the Agreement.

The Agreement has been approved by Santacruz's Board of Directors. Maxit Capital LP has provided an opinion to the Santacruz Board of Directors stating that, based upon and subject to the assumptions, limitations, and qualifications set forth therein, the consideration to be paid by Santacruz to Glencore pursuant to the Transaction is fair, from a financial point of view, to Santacruz.

Timetable and Next Steps

It is anticipated that the closing of the Transaction will take place during Q4 2021. In the coming months, Santacruz will be focused on the following activities:

• Completion of acquisition financing for the Closing Cash Payment, the terms of which are to be determined and will be disclosed when known to the Company;
• Completion of all other conditions precedent to closing of the Transaction; and
• Completion of a National Instrument 43-101 technical report on the relevant Assets to be filed in due course.

Advisors

Maxit Capital LP is acting as financial advisor to Santacruz with DuMoulin Black LLP acting as the Company's legal counsel.

In connection with the Transaction, the Company has entered into a consulting services agreement with Big Buck Capital, S.C. ("BBC") pursuant to which the Company has agreed to pay to BBC a fee equal to US$1,320,000, being 1.2% of the Transaction value (the "Success Fee"). US$320,000 of the Success Fee will be payable in cash over six months from the signing of the Agreement and US$1,000,000 will be payable in common shares of the Company upon closing of the Transaction. The deemed issue price and number of shares to be issued shall be determined based on the market price of the Company's common shares at the time of issuance, subject to TSXV acceptance.
