Vancouver, British Columbia - Luminex Resources Corp. (TSXV: LR) (the “Company” or “Luminex”) is pleased to announce the closing of its previously announced private placement financings (refer to the Company’s press releases dated April 21, 2021 and April 23, 2021) to raise an aggregate of approximately C$12.5 million (the “Offering”). A total of 10,152,000 common shares (“Shares”) were sold at a price of C$0.72 per Share (the “Offering Price”) under the brokered portion of the Offering, and an additional 7,210,000 Shares were sold at the Offering Price under the non-brokered portion of the Offering. The brokered portion of the Offering was completed through a syndicate of agents (the “Agents”) led by Haywood Securities Inc., and including PI Financial Corp., and Red Cloud Securities Inc.

The Company plans to use the net proceeds from the Offering for drilling and PEA work at its Condor project, drilling at its Cascas project and for general corporate purposes.

The Shares issued under the Offering will be subject to a statutory four month and a day hold period that will expire on September 13, 2021. In connection with the brokered portion of the Offering, the Agents received compensation of C$413,722. In connection with the non-brokered portion of the Offering, finders’ fees of 4% were paid on the proceeds from certain subscribers to Trimark Capital.

Certain related parties of the Company participated in the Offering. The issuance of common shares to related parties is considered to be a related party transaction within the meaning of TSX Venture Exchange Policy 5.9 and Multilateral Instrument 61-101 (“MI 61-101”). The Company has relied on the exemptions from the valuation and minority shareholder approval requirements of MI 61101 (and Policy 5.9) as the fair market value of the Shares issued to such persons does not exceed 25% of the Company’s market capitalization.

The Company did not file a material change report more than 21 days before the expected closing of the Offering as the details of the Offering and the participation therein by related parties of the Company were not settled until shortly prior to closing and the Company wished to close on an expedited basis for sound business reasons and in a timeframe consistent with usual market practices for transactions of this nature.
