Lumina Gold Announces US$10.2 million Wheaton Precious Metals Draw and Amendment to the PMPA

VANCOUVER, May 31, 2024 - Lumina Gold Corp. (TSXV: LUM) (OTCQB: LMGDF) (the "Company" or "Lumina") is pleased to announce that under the previously announced US$300 million precious metals purchase agreement (the "PMPA") with Wheaton Precious Metals International Ltd., a wholly owned subsidiary of Wheaton Precious Metals Corp. ("Wheaton"), the Company has drawn an additional installment of US$10.2 million. The draw consisted of two tranches, US$9 million which was due twelve months after the initial draw in May 2023 and US$1.2 million related to specific pre-construction acquisition transactions.

The PMPA has been amended to modify the US$15 million that was due in May 2024 to US$9 million payable immediately and the remaining US$6 million payable on December 2, 2024. This amendment was made because Lumina has not yet finalized terms for the exploitation contract with the Government of Ecuador, which was a condition for the US$15 million being received. The December 2, 2024 payment is conditional on the finalization of the exploitation contract term sheet between Lumina and the Government of Ecuador.

Lumina Gold Corp. (TSXV: LUM) is a Vancouver, Canada based precious and base metals exploration and development company focused on the Cangrejos Gold-Copper Project located in El Oro Province, southwest Ecuador. In 2023, the Company completed a Pre-Feasibility Study for Cangrejos, which is the largest primary gold deposit in Ecuador. Lumina has an experienced management team with a successful track record of advancing and monetizing exploration projects.
