Montero Provides Hearing Date for ICSID Arbitration Claim

against the Government of Tanzania

Toronto, Ontario – June 10, 2024 – Montero Mining and Exploration Ltd. (TSX-V: MON) (“Montero” or the

“Company”) provides an update on the arbitration proceedings against the United Republic of Tanzania (“Tanzania”)

over the expropriation of the Wigu Hill rare earth element project (“ Wigu Hill”) before the International Centre for

Settlement of Investment Disputes (“ICSID”).

The Tribunal has set new dates for the hearing which will take place from November 25th to 29th 2024, at the Paris

Arbitration Centre, Paris, France. After the previous hearing date was postponed, the Tribunal preferred to keep the

hearing in person and decided to move the hearing dates to accommodate all parties.

Dr Tony Harwood, President and CEO of Montero commented: “Montero is pleased that a new hearing date has

been decided by the Tribunal. We are ready to present our case at the hearing which will be open to the public and

which recordings will be made available online. We are optimistic of a positive outcome given the Indiana Resources

judgement for US$ 113 million , plus legal costs, and Winshear Gold’s settlement of US$ 30 million , both of which

were concluded in 2023 and led by Montero’s lead attorney Timothy Foden.”

Montero is represented by Timothy Foden of Boies Schiller Flexner (UK) LLP and Martin Tavaut of Jeantet AARP I.

Timothy Foden is leading the ICSID arbitration for Montero. Montero has retained Dr. Neal Rigby of SRK Consulting

(USA) Inc. as quantum expert with full dispute funding secured from Omni Bridgeway, a leading global dispute

funder.

Montero’s dispute with Tanzania is also subject to ICSID arbitration. Montero is seeking compensation in excess of

CDN$ 90,000,000 in damages from Tanzania over the expropriation of the Wigu Hill rare earth element project .

Montero is also seeking reimbursement of its arbitration costs and fees by Tanzania. The damages claimed are for

Tanzania’s breaches of the BIT between Canada and Tanzania. On May 16, 2024, Indiana Resources Limited provided

a corporate update that the company’s total award was approximately US$ 123 million with interest on this award

and is accruing at a rate of US$ 1 million per month. Montero has experienced nearly a year's delay in rescheduling

the arbitration hearing, despite the delay, high interest rates may be beneficial to the Company if the judgment is in

Montero's favour and includes interest rates.

For further information, please see Montero’s recent press releases dated December 1st, 2023, November 14th,2023,

September 21st, 2023, July 19 th, 2023, April 25 th, 2023, July 28 th, 2022, April 12 th, 2022, November 29 th, 2021, and

January 8th, 2021, and the ICSID website.

The ICSID Convention has been ratified by 158 States, including Tanzania. An award issued by an ICSID tribunal is

enforceable in any one of those 158 member States as if it were a judgment of one of their own courts. Partly

because of this, States often comply voluntarily with the payment terms of such awards.
