Temas Announces Filing of Positive Preliminary Economic Assessment for Piskanja Boron Project

US$524.9 Million NPV10 (post-tax), 78.7% IRR (post-tax), 12-Month Capex Payback

Boron is critical for decarbonization as a high-impact, cross-cutting super material.

Temas Resources Corp.(“Temas” or the “Company”)[CSE: TMAS]and their partner Erin Ventures Inc. [TSXV: EV] are pleased to report the filing of an Independent Technical Report providing the Preliminary Economic Assessment (“PEA”) for the Piskanja boron project located in Serbia on SEDAR, as per the terminology, definitions and guidelines given in the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Standards on Mineral Resources and Mineral Reserves (May 2014) as required by NI 43-101 ("The CIM Code"). The CIM Code is an internationally recognized reporting code as defined by the Committee for Mineral Reserves International Reporting Standards. The filing follows press release dated June 28, 2022 summarizing the PEA including sensitivity analyses, highlights being repeated below.

PEA HIGHLIGHTS

Note:
All values in this news release are reported in U.S. dollars unless otherwise noted
Assumed price/t (colemanite 40% B2O3) for LOM: US$500
Assumed price/t (boric acid, technical grade) for LOM: US$700
Units expressed in metric tonnes

MINERAL RESOURCES

The basis for the PEA is the Mineral Resource Estimate prepared by Prof. Miodrag Banješevic PhD. P.Geo, EurGeol.

The updated Mineral Resource Statement generated for the Piskanja Project is as followings:

Reported at a cut-off grade of 12 percent B2O3, at a minimum mining thickness of 1.2 m, considering reasonable underground mining, processing and selling technical parameters and costs benchmark against similar borate projects and a selling price of US$700/tonne (boric acid) and US$500/tonne (colemanite 40% B2O3). All figures are rounded to reflect the relative accuracy of the estimates. Mineral Resources are not Mineral Reserves and do not have a demonstrated economic viability. The contained B2O3 represents estimated contained metal in the ground and has not been adjusted for metallurgical recovery, and may have discrepancies due to rounding.

The PEA was prepared independently by, and under the supervision of, Prof. Miodrag Banješevic PhD. P.Geo, EurGeol, with contributions from Prof. Saša Stojadinovic PhD. (mining engineer). The PEA was prepared in accordance with the requirements of National Instrument 43-101 and is based on the Mineral Resource Estimate for Piskanja with an effective date of June 24, 2022 (see “Mineral Resource” above).

CAUTIONARY NOTE

The PEA summarized in this news release is considered preliminary in nature, contains numerous assumptions and includes Inferred Mineral Resources that are considered too speculative, geologically, to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. There is no certainty that the results of the PEA will be realized. No Mineral Reserves have been estimated for Piskanja. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Inferred Mineral Resources are that part of the Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geologic evidence and sampling, which is sufficient to imply but not verify grade or quality continuity. Inferred Mineral Resources may not be converted to mineral reserves. It is reasonably expected, though not guaranteed, that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. Mineral Resources are captured within an optimized mine plan (within the constraints of a PEA) and meet the test of reasonable prospects for economic extraction.

The effective date of the PEA is June 24, 2022, and a technical report prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101“) in support of the PEA will be filed on SEDAR within 45 days of this news release.

Temas also wishes to announce that it has closed a non-brokered private placement (the “Private Placement”) of 500,000 common shares at a price of $0.06 per common share. The Private Placement constituted a secondary drawdown of the $5 million equity investment facility with Crescita Capital LLC.

Cautionary Note to United States Investors

Temas Resource Corp. prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Terms relating to mineral resources in this news release are defined in accordance with NI 43-101 under the guidelines set out in CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the Canadian Institute of Mining, Metallurgy and Petroleum Council on May 19, 2014, as amended (“CIM Standards”). The U.S. Securities and Exchange Commission (the “SEC”) has adopted amendments effective February 25, 2019 (the “SEC Modernization Rules”) to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934.

As a result of the adoption of the SEC Modernization Rules, the SEC will now recognize estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”, which are defined in substantially similar terms to the corresponding CIM Standards. In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be substantially similar to the corresponding CIM Standards.

U.S. investors are cautioned that while the foregoing terms are “substantially similar” to corresponding definitions under the CIM Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Standards. Accordingly, there is no assurance any mineral resources that Temas may report as “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had Temas Resource Corp. prepared the resource estimates under the standards adopted under the SEC Modernization Rules.

In accordance with Canadian securities laws, estimates of “inferred mineral resources” cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43-101.

NEITHER THE CSE NOR ITS REGULATION SERVICES PROVIDER (AS THAT TERM IS DEFINED IN THE POLICIES OF THE TSX VENTURE EXCHANGE) ACCEPTS RESPONSIBILITY FOR THE ADEQUACY OR ACCURACY OF THIS RELEASE.
