Temas Resources Enters Strategic Partnership with Erin Ventures for

Development of Erin’s Piskanja Boron Project

VANCOUVER, British Columbia, December 17, 2020 Temas Resources Corp. (the “Company”

or “Temas Resources”( (CSE: TMAS, OTCQB: TMASF), is pleased to announce that it has

entered into a letter of intent with Erin Ventures Inc. (“Erin”) for the joint development of

Erin’s Piskanja Borate Project, located in Serbia (“Piskanja”).

Piskanja is Erin’s wholly owned boron deposit with an indicated mineral resource of 7.8 million

tonnes (averaging 31.0 per cent B 2O3), and an inferred resource of 3.4 million tonnes

(averaging 28.6 per cent B2O3), calculated in accordance with the Canadian Institute of Mining

Definition Standards on Mineral R esources and Reserves (CIM Standards), as disclosed in

Erin’s report titled, “Mineral Resource Estimate Update On The Piskanja Borate Project, Serbia,

October 2016 - Amended February 28 2019” - prepared by SRK Consulting (UK) Ltd. The

responsible persons f or the Updated MRE are Dr Mike Armitage (C.Eng. C.Geol.) and Dr

Mikhail Tsypukov who are both employees of SRK and Qualified Persons in accordance with

the CIM Definition Standards on Mineral Resources and Reserves (CIM Standards), and

independent of Erin Ventures.

The salient terms in the letter of intent (“LOI”) as are follows:

 Upon execution of a definitive option agreement (the “Option Agreement”), Temas will

have the sole, exclusive, immediate, and irrevocable option to earn up to 50% equity

interest in Balkan Gold (Erin’s wholly owned subsidiary which holds the license to the

Piskanja Boron Project) by expending a total of €10.5 million towards the development

of Piskanja, within a 36 -month period (subject to acceleration at the election of Te-

mas).

 Upon receiving necessary regulatory approvals, Temas will make a one-time payment

of 250,000 Temas common shares and 250,000 share purchase warrants (at $1.00 for

4 years) to Erin.

 The terms of the LOI will form the basis of the Option Agreement, which the p arties

contemplate will be entered into no later than April 15, 2021.

 Temas has until February 28, 2021 to complete its due diligence regarding Piskanja.

 Each €210,000 advanced to the Project by Temas will earn Temas an additional 1%

undivided equity interest in Balkan Gold, to a maximum of 50% interest for €10.5M.

 Upon acquisition of 50% interest in Balkan Gold by completing its expenditures, Temas

will be entitled to representation on the board of Balkan Gold, voting rights, and dilu-

tion provisions, among other rights regarding the governance of Balkan Gold.

 The Option Agreement will include standard dilution provisions.

 Erin will remain operator on the project until such time as Temas has exercised the

Option and earned its 50% interest in Balkan Gold, at which point Temas will become

operator of Piskanja.

 During the three year option period, a joint technical committee made up of members

from both Erin and Temas will have final say on matters pertaining to programs and

budgets.

 This LOI is non-binding, with the terms subject to the parties entering into a binding

Option Agreement.

 The Option Agreement will be subject to satisfactory completion of due diligence, ap-

plicable regulatory approvals, board approvals, shareholder approvals as may be re-

quired, amongst other factors.

“We are extremely excited by this development” said Tim Daniels, CEO of Erin. “Temas is an

exceptionally good fit for this project. Not only are they willing to match their funding

commitments for Piskanja, with the anticipated equity requirements for project development

right through to production, but in addition, they have an experienced management team

with like-minded thinking towards the development of Piskanja. Undoubtedly we are stronger

with them as our partner.”

Michael Dehn, CEO of Temas stated “having the ability to work on a great project and high

demand commodity, that would be the only European production of borates that should add

significant shareholder value. When considering Piskanja, alongside our Ilmenite deposits in

Canada, we believe that Temas is becoming a very compelling story. Having access to premier

projects that could produce products that end up in consumer and industrial products is

intended to allow Temas evolve from an explorer to producer.”

Piskanja is located in a historical mining region that has excellent infrastructure for mining

including roads, rail, electric power, experienced miners, and is 250 km south of Belgrade,

Serbia by paved roads. Erin Ventures reported on August 31, 2010, that it had been granted

a license for the Piskanja boron deposit in Serbia by the Serbian Ministry of Mining and Energy.

The license includes the entire known historical mineralized area along with a substantial

amount of previously unexplored ground.

1Mineral Resources are not Mineral Reserves as they have no demonstrated economic viability.

Temas is not aware of any factors (environmental, permitting, legal, title, taxation, socio -

economic, marketing, political, or other relevant factors) that have materially affected the

Mineral Resource Estimate.

2Inferred mineral resources are considered too speculative geologically to have economic

considerations applied to them that would enable them to be categorized as mineral reserves.

There is also no certainty that these inferred mineral resources will be converted to the

measured and indicated categories through further drilling, or into mineral reserves, once

economic considerations are applied.

3Contained metal figures and totals may differ due to rounding of figures.

Effective date of resource estimate February 28, 2019

Assumptions used to derive the cut-off grades in order to meet the NI43-101 requirement for

mineral resource estimates to demonstrate "reasonable prospects for eventual economic

extraction". The estimate assumes:

- An average production of 330,000tpa,

- Mean mining grade of 27.8% B2O3

- All Run of Mine (RoM) ore to report to a Colemanite Plant for Colemanite production.

- A mean mass yield of RoM ore to Colemanite product of 73.8%.

- An average recovery of B2O3 from RoM ore to Colemanite of 92.9%.

- ~ 50,000tpa of Colemanite product (at 35% B2O3) to be subsequently processed to

produce 25,000tpa of Boric Acid product with an assumed grade of 56.3% B2O3. The

remaining Colemanite product is sold.

- A mean mass yield of Colemanite to Boric Acid product of 49.7% and an assumption

that 80% of the B2O3 is recovered to the product.

- A Colemanite (at 35% B2O3) price of USD400/t product.

- A Boric Acid (at 56.3% B2O3) price of USD800/t product.

- Royalty deduction of 5% on gross revenue.

- Other sales and marketing costs of USD1.5/t product sold.

- Total Construction Costs of US$85Million.

- Sustaining Capital Costs of US$19Million.

- Closure Costs of US$15Million

- Operating Costs of US$170/tonne product
