Minsud Exercises Option to

Acquire 100% of the Brechas Vacas Property

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

pleased to announce that Minera Sud Argentina S.A. (“ MSA”), the Company’s Argentine indirect

subsidiary, has exercised its option to purchase the remaining 50% beneficial interest in the Brechas

Vacas Trust, and has become the indirect owner of 100% of the Brechas Vacas property. The Brechas

Vacas property represents one of the main properties in the Company’s flagship Chita Valley Project.

MSA has paid the required sum of US$735,000 to the Brechas Vacas owners representing the price to

fully exercise the option, which was settled in Argentinean pesos.

On September 7, 2007, MSA entered into an exploration agreement including a purchase o ption (the

"Initial Brechas Vacas Agreement ") with the owners o f the mining properties (the " Brechas Vacas

owners") identified as Proyecto Brechas Vacas, located in the Chita Valley, in the Province of San

Juan, Argentina (the “Brechas Vacas property ”). In addition to the exploration rights, the Brechas

Vacas owners granted to MSA , an irrevocable and exclusive option to purchase a 50% ownership

interest in the property.

On September 6, 2011, MSA exercised its option to purchase a 50% ownership interest in the Brechas

Vacas property for consideration of US$210,000. Subsequent to exercising this option, the ownership

of the Brechas Vacas property was transferred by the Brechas Vacas owners to the Brechas Vacas

Trust and MSA simultaneously acquired a 50% beneficial interest in the Brechas Vacas Trust. The

remaining 50% beneficial interest in the Brechas Vacas Trust held by the Brechas Vacas owners was

subject to a new exclusive and irrevocable purchase option agreement (the “ BV Option Agreement”)

dated January 3, 2012 granted in favour of MSA, and amended on December 19, 2013, June 24, 2016

and June 24, 2019. The option under the BV Option Agreement can be exercised by MSA at any time

on or before June 26, 2022 and provides MSA with an irrevocable and exclusive right to purchase the

remaining 50% beneficial interest in the Brechas Vacas Trust in exchange for a cash payment of

US$735,000 in addition to the exclusive right to evaluate, prosp ect and explore the Brechas Vacas

property.

The Brechas Vacas owners will retain a 0.6% Net Smelter Return ("NSR") royalty on the Brechas Vacas

property with the Company having the option to purchase 0.3% of the 0.6% NSR royalty, at any time,

for a one-time payment of US$400,000.

Ramiro Massa, Minsud’s President and CEO, states: “We are excited to close the acquisition of 100%

ownership of the Brechas Vacas property. This property is an important piece of our flagship Chita

Valley Project and this ac quisition represents a considerable footprint for our company and moves us

one step closer to advancing the greater mission of developing the Chita Valley Project.”

About the Chita Valley Project, San Juan Province:

The Chita Valley Project is a large exploration stage porphyry system with classic alteration features,

widespread porphyry style Cu -Mo-Au and polymetallic Ag -Pb-Zn mineralization hosted by

Hydrothermal Phreatic Breccias and associated gold and silver -bearing polymetallic veins of

intermediate sulfide composition that conformed an outcropping porphyry system at Chita and a

lithocap of a porphyry system at Chinchillones. San Juan Province of Argentina has a robust mining

sector and recognizes the important economic benefits of responsible deve lopment of its substantial

Mineral Resource endowment.

Current exploration activities on the Chita Valley Project are being funded by a subsidiary of South32

in accordance with the earn-in agreement between the parties entered into on November 1, 2019.

The earn-in agreement grants to South32 the right to acquire a 50.1% direct interest in the Company’s

Argentinean operating subsidiary Minera Sud Argentina S.A. (“MSA”) at the end of the earn -in period.

Under the earn-in agreement, South32 will provide fur ther funding to MSA over the next 3 years such

that its aggregate funding is (i) not less than C$7 million by December 31, 2021; (ii) not less than C$10.5

million by December 31, 2022; and (iii) not less than C$14 million by December 31, 2023. South32 has

the right to withdraw at the end of each year.

If South32 exercises its earn-in right it may elect to fund a pre -feasibility study, with a minimum spend

of C$41 million, which would entitle it to elect to increase its 50.1% direct interest in MSA to 70%.
