The Issuer’s Annual Information Form for the year ended December 31, 2023 did not include disclosure for Richard Contreras, the Issuer’s Chief Operations Officer, as an executive officer of the Issuer as required under Form 52-102F2 Annual Information Form.

The NI 43-101 Technical Report: Preliminary Economic Assessment, Reliquias Mine had disclosed a series of exploration targets with tonnages are grades which were not categorized as measured, indicated, or inferred resource or proven or probable reserves. The tonnages and grades were also not expressed as ranges, which would be acceptable under NI 43-101 Standards of Disclosure for Mineral Projects.

The Issuer amended and refiled the Butiá Technical Report and the Cerrito Technical Report to include additional disclosure regarding: (i) assumptions used to support the cut-off grade; (ii) constraining the mineral resources within a conceptual pit shell to demonstrate reasonable prospects for eventual economic extraction; (iii) rounding the mineral resource estimates to significant figures; and (iv) clarifying that the independent qualified person is responsible for all items of the Technical Reports. The Issuer also revised its website and corporate presentations regarding: (i) use of the phrase "NI 43- 101 compliant" related to estimation of mineral resources; (ii) adding inferred resources to other categories of resources prohibited by paragraph 2.2(c) of NI 43-101; and (iii) use of the term “potential world-class” related to the Issuer’s property.

The Issuer re-filed the plea agreements (with appendices) related to its U.S. Bank Secrecy Act and Anti-Money Laundering compliance programs, entered into with the Department of Justice, Criminal Division, Money Laundering and Asset Recovery Section and the United States Attorney’s Office for the District of New Jersey (“DOJ”) as material contracts on SEDAR+. The plea agreements were previously filed as “other” on SEDAR+ without the appendices as required by National Instrument 51-102 Continuous Disclosure Obligations.

Reason(s) The Issuer did not previously file its credit agreement and associated amendments in respect of its senior funding facility as material contracts as required by National Instrument 51-102 Continuous Disclosure Obligations
