• 2,500 metre initial drill program planned to commence during Q1 2022

Vancouver, British Columbia – Luminex Resources Corp. (TSXV: LR) (OTCQX: LUMIF) (the "Company" or "Luminex") is pleased to announce that on December 29, 2021, it entered into a binding interim agreement (the "IA") for an earn-in and joint venture with Japan Oil, Gas and Metals National Corporation ("JOGMEC"), on Luminex's Orquideas mineral concession in Ecuador. JOGMEC has the right to earn a 70% ownership interest in Orquideas by investing an aggregate US$7 million between now and March 31, 2026. Luminex and JOGMEC will work to conclude a definitive agreement in due course. Luminex will manage and operate the exploration programs for Orquideas and will receive a management fee based on expenses.

Marshall Koval, CEO and Director commented: "The Company is pleased to partner with JOGMEC and is happy to see that additional drilling will be completed on this property. This earn-in agreement continues Luminex's strategy of looking for high caliber partners to de-risk its large portfolio of properties in Ecuador. With BHP drilling Tarqui now, Anglo American planning to start drilling by mid-year and JOGMEC drilling during Q1, it will be an extremely active year on the Company's copper focused projects."

About Orquideas

Orquideas is a porphyry copper and molybdenum mineralized system hosted in phases of the mid Jurassic Zamora Batholith. The exploration project is located 40 km south of Lundin Gold Inc.'s Fruta Del Norte epithermal gold and silver mine and approximately 15 km southwest of Luminex's Condor project, which contains epithermal gold and silver as well as gold and copper porphyry resources. The geochemical footprint of Orquideas extends northwest by southeast for 5.5 km and is 2 km wide.

Initial Work Plan

Luminex will work to establish trails and access to the proposed drill sites in early Q1 2022 and then commence a 2,500-metre initial drill program across five planned holes. It is anticipated that this work program will fulfill the JOGMEC earn-in commitment to 2023 (see below schedule).

Summary of Key Terms Contemplated by IA

The IA envisages a five period earn-in with the following expenditure schedule:

JOGMEC will have the right to accelerate the exercise of the earn-in by completing all the exploration expenditures in a period shorter than the earn-in term. JOGMEC also has the right to withdraw from the earn-in after the first period's expenditures of US$0.75 million. 70% ownership by JOGMEC will occur only after the entire earn-in expenditure has been completed; there is no phased earn-in.
