Minsud Announces Exercise of Earn-In Right by South32 to

Acquire a 50.1% Interest in its Argentinian Subsidiary

TORONTO, ONTARIO – Minsud Resources Corp. (TSX -V: MSR) (“Minsud” or the

“Company”) is pleased to announce that , further to the Company’s press release dated

November 4, 2019, South32 Alumini um (Holdings) Pty Ltd. (“ South32”) a wholly owned

subsidiary of South32 Limited, has exercised its earn- in right (the “Earn-In Right”) to acquire

a 50.1% ownership interest in Minera Sud Argentina S.A. (“ MSA”), Minsud’s indirect

Argentinian subsidiary that holds and operates the flagship Chita Valley Project.

In accordance with the terms of the earn-in agreement dated November 1, 2019, as amended

(the “Earn-In Agreement”) between South32 and Minsud, South32 had the right to exercise

its Earn -In Right upon advancing initial capital contributions to MSA of no less than C$14

million (the “South32 Initial Capital Contribution”) for a period of four years in order to fund

MSA’s exploration programs. South32 advanced the South32 Initial Capital Contribution within

a period of three years and has, in accordance with the Earn-In Agreement, exercised its Earn-

In Right to acquire 50.1% of MSA.

Completion of South32’s acquisition of 50.1% of the shares in MSA (“Completion”) shall take

place on the earlier of : (i) the completion of the Year 4 annual exploration program ; and (ii)

February 14, 2024.

At the time of Completion, Minsud Argentina Inc. (“ MAI”), a wholly owned subsidiary of the

Company, and South32 will enter into a shareholders' agreement to govern the management

and operation of MSA which will include further exploration and, if economically feasible, the

development and exploitation of the Chita Valley Project (the “Shareholders’ Agreement”).

Until Completion, MAI shall continue to manage and operate MSA and, therefore, the Chita

Valley Project.

As part of the exercise of the Earn-In Right the parties to the Earn-In Agreement have agreed

to certain amendments to the Earn-In Agreement and the Shareholders’ Agreement, including:

• The exercise of the Earn- In Right by South32 is confirmed and certain other optional

earn-in rights in favour of South32 relating to the funding of a prefeasibility study and a

bankable feasibility study are removed.

• MAI shall be entitled to elect, prior to Completion, whether South32’s acquisition of the

50.1% stake in MSA will be effected by means of:

(i) South32’s subscription for MSA shares in consideration for the South32 Initial

Capital Contribution (the “Cash In Option”); or

(ii) a combination of a subscription for 10% of MSA shares combined with a sale of

40.1% of MSA shares from MAI to South32 (the “Cash Out Option”).

• Previously, the Earn-In Agreement provided that on exercise of the Earn-In Right South32

would pay an amount of C$14 million to MAI (the “ Transfer Price”) which is in addition

to the South32 Initial Capital Contribution. The amendments to the earn- In Agreement

now provide that:

(i) Whilst South32 has already committed to fund C$9.1 million for the Year 4

exploration program (of which C$2.6 million has already been contributed) 49.9% of

the C$9.1 million Year 4 exploration program will now be funded by MAI by way of this

amount being deducted from the Transfer Price;

2

(ii) If MAI opts for the Cash Out Option, the n South32 shall pay the balance of the

Transfer Price to MAI on Completion and for a period of twenty-four (24) months from

the date on which the Shareholders’ Agreement is signed, and provided that MAI

reinvests the balance of the Transfer Price in approved MSA programs and budgets ,

then MAI’s 49.9% share in MSA shall not be diluted; and

(iii) If MAI opts for the Cash In Option, then MAI will not be obliged to contribute any

amount to an approved program and budget until the aggregate of the South32 Initial

Capital Contribution and the amounts contributed and funded by South32 in respect

of MSA approved programs and budgets following the South32 Initial Capital

Contribution equals C$42 million.

Ramiro Massa, Minsud’s President & CEO, said: “During these past three years, Minsud has

been challenged to meet the high operating and exploration standards of a global mining

company. This challenge came together with our biggest opportunity to explore our Chita

Valley Project, and fortunately we have been able to deliver high quality exploration results,

with a significant new discovery at the Chinchillones target, while taking care of the

environment and our community. We are very proud and excited to advance this partnership

with South32. I want to congratulate our team, our board, and our investors who have al ways

believed in us and in the potential of the Chita Valley Project”.
