Drill Results

Minsud reports 448m at 1.20% CuEq; expands

polymetallic (Zn-Pb-Cu-Ag-Au) and porphyry Cu-Mo-Ag-Au

mineralization at the Chita Valley Project

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

pleased to announce receipt of assay results from the additional eight (8) drillholes completed in the

ongoing Phase 3 program over the Chinchillones area, located at the Chita Valley Project, San Juan

province, Argentina. The Company is complet ing the largest annual drilling program over the Chita

project area, encompassing approximately 12,000 meters by the end of December 2021.

A total of twenty-four (24) drillholes are being completed by the end of this year. Twenty (20) drillholes

have been reported through several previous press releases with remaining four (4) drillholes awaiting

assay results.

Highlights are listed below, along with the accompanying figures. Scout drillholes CHDH21 -33 to

CHDH21-35 were drilled outside of the principal Chinchillones area.

• CHDH21-37 is the deepest drillhole of the project with 852 m depth. The most significant intercepts

included 448m with 1.20% CuEq; 3.59% ZnEq, from 404m to 852m EOH (0.29% Cu, 0.13 g/t Au,

24.08 g/t Ag, 353 ppm Mo, 0.27% Pb, 1.17% Zn) and a higher-grade zone of 114m from 490m at

2.67% CuEq; 8.00% ZnEq (0.52% Cu, 0.34 g/t Au, 67.30 g/t Ag, 0.79% Pb, 3.46% Zn).

This drillhole , with a NNW azimuth, dipping 80° , aimed at testing the extent of high-grade

polymetallic mineralization intersected at CHDH21-23 (please see press release dated August 26,

2021). High-grade intervals are hosted in magmatic-hydrothermal breccias from 409m to 600m,

with abundant sulphides in the breccia matrix. The breccia progresses at depth to a finer-grained

dioritic porphyry containing pervasive Cu-Mo mineralization within type “B” veins, accompanied by

strong sericite-quartz-pyrite alteration, until the end of the drillhole.

The mineralized diorite s intercepted at depth in CHDH21 -37, together with those observed in

drillholes CHDH21-23, 28, 04 and 38, confirmed the presence of a porphyry mineralized body, from

around 500m below surface extending down-dip to at least 850m. From the drilling conducted so

far, the apparent NS-trending porphyry body is at least 500m-long and 270m-wide.

The higher-grade polymetallic mineralization from 102m occurs in a zone characterized by well -

developed sulphide-cemented hydrothermal breccias and high-density vein network of sphalerite–

chalcopyrite-galena-pyrargyrite-tennantite-native silver which is demonstrably superimposed on

the Cu-Mo-Ag-Au porphyry body.

• CHDH21-38 intersected 387m at 0.50% CuEq, from 340m to 727m. (0.25% Cu, 0.06 g/t Au, 9.06

g/t Ag, 111 ppm Mo). This drillhole is located 250m NE of CHDH21-37, heading S, dipping 75° with

727m depth. This drillhole intersected mineralized dacitic and dioritic rocks. The principal Cu-Mo-

Ag-Au mineralization occur as disseminations, and in thin quartz type “B” and “A” veinlets of pyrite-

chalcopyrite and chalcopyrite -bornite. In conjunction with drillhole CHDH21-37 these drillholes

confirmed the presence of Cu -Mo porphyry at depth and demonstrate that the porphyry body is

open in various directions. Molybdenum values remarkably increased through to the end of the

drillhole, indicating further potential at depth.

The substantial and high-grade Zn-Pb-Ag-Cu-Au and Cu-Mo-Ag-Au mineralization at CHDH21-37 and

CHDH21-38 confirm the potential of Chinchillones to host high-grade polymetallic mineralization

transitioning to prospective cluster of porphyry Cu centres.

Ramiro Massa, Minsud’s President & CEO, commented: “We continue to be excited and encouraged

by results from our ongoing Phase 3 drilling program. This year we discovered a new porphyry center

at Chinchillones area with Cu-Mo mineralization overprinted by a hydrothermal system Zn-Pb-Cu-Ag-

Au. Our exploration program has expanded our understanding of the project and dramatically increased

its potential. We continue our ongoing exploration program and anticipate furthe r encouraging results

with support from our partner South32”.

Quality Assurance/Quality Control

All core samples were submitted to the ALS Global Laboratories in Mendoza, Argentina for preparation

and analysis. All samples were analyzed for Au by fire assay/ AA finish 50g, plus a 48 -element ultra-

trace four acid digest with ICP-MS and ICP-AES finish. Minsud followed industry standard procedures

for the work with a quality assurance/quality control (QA/QC) program. Field duplicates, standards and

blanks were included with all sample shipments to the principal laboratory. Minsud detected no

significant QA/QC issues during review of the data.

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 Pr ovince of Argentina has a robust mining

sector and recognizes the important economic benefits of responsible development of its substantial

Mineral Resource endowment.

Current exploration activities on the Chita Valley Project are being funded by a subsidi ary 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, and having given the Company notice of its intention to continue funding

Chita Valley Project, South32 will prov ide further funding to MSA over the next 2 years such that its

aggregate funding is (i) not less than C$10.5 million by December 31, 2022; and (ii) 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%.
