VANCOUVER, British Columbia, June 17, 2021 ― Temas Resources Corp. (CSE: TMAS, OTCQB: TMASF, FSE: 26P) (the “Company” or “Temas Resources”), is pleased to announce that, further to its news release dated December 18, 2020, the Company and Erin Ventures Inc. have now entered into a definitive option and joint venture agreement dated June 16, 2021 (the “Option Agreement”) for the joint development of Erin Ventures’ Piskanja Borate Project located in Serbia (the “Piskanja Project”).  

“We are thrilled to enter into this definitive option agreement with Erin Ventures,” states Michael Dehn, President and CEO of Temas Resources. “At Temas we are looking forward to furthering the development of the Piskanja Boron Property in Serbia along-side Erin Ventures.” Mr. Dehn added, “We have jointly developed a very robust exploration plan and anticipate announcing details in the coming weeks.”  

Pursuant to the Option Agreement, Temas Resources may earn a 50% interest in the Piskanja Project by (a) issuing to Erin Ventures 250,000 common shares and 250,000 Temas warrants (each exercisable to acquire a common share for a period of 48 months from issuance, at an exercise price equal to the market price of the common shares less the maximum allowable discount pursuant to stock exchange policies) within five business days after the effective date of the Option Agreement, and (b) incurring an aggregate of €10,500,000 in expenditures on the Piskanja Project.

Boron is an essential mineral and is found in everything from eye drops, mild antiseptics, a supplement for building stronger bones and muscles to boric acid, which is used to toughen and increase heat resistance in Pyrex.
