LUCA CLARIFIES TRAFIGURA EARLY WARNING REPORT

Vancouver, British Columbia, August 27, 2024

Luca Mining Corp. (“ Luca” or the “ Company”) (TSX -V: LUCA; OTCQX: LUCMF; Frankfurt: Z68)

wishes to clarify a Form 62- 103F1 Early Warning Report (the “ EWR”) issued today by Trafigura

Beheer B.V. (“Trafigura”).

The EWR relates to a debt restructuring agreement entered into between Luca and Trafigura on

December 11, 2023. The debt restructuring related to the conversion of an outstanding loan in the

amount of US$5,800,000 (the “Principal Amount”) into a non -interest-bearing three -year term

convertible debenture (the “ Convertible Debenture”). The transaction was announced by the

Company through news releases dated December 6, 2023 and January 19, 2024.

As Trafigura wished for the Convertible Debenture to be held by its subsidiary Urion Holdings (Malta)

Limited (“Urion”) and the Convertible Debenture was to be secured, the Convertible Debenture was

conditionally issued into escrow, subject to being formally executed and released once Trafigura and

the Company were able to amend existing security agreements to insert Urion into same (the

“Condition Precedent”). That process has taken several months and was finally completed in Mexico

last week, such that the Condition Precedent was met, and Convertible Debenture could be formally

perfected and released from escrow.

The Convertible Debenture matures on January 11, 2027 and should Urion choose to convert same,

then based on a US$ conversion price to CAD$ of 1.30602 as of August 22, 2024, the conversion of

the Convertible Debenture would result in Urion acquiring approximately 22,540,457 common

shares in the capital of Luca ( the “Luca Shares”), representing approximately 11.65% of the Luca

Shares (after giving effect to the conversion of the full amount of the Convertible Debenture). Should

that event occur, then Trafigura would own indirectly through Urion 24,365,457 Luca Shares,

representing approximately 12.48% of the issued and outstanding Luca Shares, based on

170,862,081 Luca Shares being currently outstanding. Even though the Convertible Debenture was

issued into escrow in January this year, since Trafigura, indirectly through Urion has just perfected

the right to acquire the above shareholding in Luca, it was required to issue the EWR upon the

Convertible Debenture finally being signed and released from escrow.

At the time the time the debt restructuring was agreed, Luca’s shares were trading at CAD$0.29. The

Convertible Debenture has not been converted and neither Trafigura nor Urion have given Luca any

indication whether they intend to convert same. In the meantime, the Company receives the benefit

of a non-interest-bearing loan facility.

The Company continues to enjoy an excellent working relationship with Trafigura, which has offtake

agreements in place for both the Campo Morado and Tahuehueto mines.

Cautionary Note Regarding Production Decisions and Forward-Looking Statements

a feasibility study of mineral reserves demonstrating economic and technical viability. Accordingly,

readers should be cautioned that Luca’s production decision has been made without a

comprehensive feasibility study of established reserves such that there is greater risk and

uncertainty as to future economic results from the Campo Morado mine and a higher technical risk

of failure than would be the case if a feasibility study were compl eted and relied upon to make a

production decision. Luca has completed a preliminary economic assessment (“PEA”) mining study

on the Campo Morado mine that provides a conceptual life of mine plan and a preliminary economic

analysis based on the previously identified mineral resources (see news releases dated November 8,

2017, and April 4, 2018).

Furthermore, Luca intends to declare commercial production at t he Tahuehueto gold, silver mine

prior to completing a feasibility study of mineral reserves demonstrating economic and technical

viability. Accordingly, readers should be cautioned that Luca’s production decision has been made

without a comprehensive feasibility study of established reserves such that there is greater risk and

uncertainty as to future economic results from the Tahuehueto gold, silver mine and a higher

technical risk of failure than would be the case if a feasibility study were completed and relied upon

to make a production decision. Luca has completed a prefeasibility study on the Tahuehueto gold,

silver mine (see news releases dated April 26, 2022).
