Minsud Encounters 767m at 0.25% Cu, 0.05 g/t Au, 4.91 g/t Ag

Chinchillones, Plans Mineral Resource Estimate

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

to announce the receipt of assay results from nine (9) additional drillholes, which were completed as part

of the ongoing Phase IV drilling program at the Chita Valley Project, San Juan Province, Argentina.

Fifty-two (52) drillholes have been completed to date in the Phase IV program, encompassing a total of

38,991 metres. Assay results have been received from drillholes CHDH23 -82 through CHDH23-90, which

total 8,186 metres. Four additional drillholes, CHDH23 -91 through CHDH23-94, are currently awaiting

assay. Key highlights and associated figures are provided below.

Chinchillones HS E Target NNE: High -grade body with mineralizatio n extending between 800 to

1,000m depth

Continued drilling in Phase IV was mainly concentrated in the SW -NE corridor at the eastern end of the

Chinchillones target. Drilling tested the lateral and depth continuity of the previously reported drillholes

CHDH23-73 and CHDH23-62, the High-Grade sector of the main mineralized bodies.

Drilling intersected porphyritic dacite bodies with disseminated and early mineralization hosted in veinlets,

with marked advanced argillic alteration, superimposed on quartz-sericitic alteration of the early bodies at

depth. These dacites are cross-cut by high-grade hydrothermal -intrusive breccias. Cu -Au mineralization

occurs disseminated in the porphyritic dacite and largely within the breccia matrix. The geometry and extent

of this zone has not yet been fully established, but this confirms the high -grade mineralization found at

depth in previously reported holes.

CHDH23-82 was drilled with an orientation of 315°/-75° to a depth of 921 metres:

 Significant Drill Intercepts:

o 767.0m @ 0.25% Cu, 0.05 g/t Au and 4.91 g/t Ag, from 154m depth.

 including 18.0m @ 0.95% Cu, 0.21 g/t Au, 10.06 g/t Ag, from 684m depth.

 Geology:

o The drillhole was comprised of intercalated phreatomagmatic breccia and fine to medium

grained porphyritic dacite, with m oderate to strong advanced argillic alteration with

pyrophyllite and k aolinite. Few local pyrite veins with moderate (3 -5%) disseminated

chalcopyrite, chalcocite, and pyrite. 5 to 10 cm HS veins b etween 380 to 400 m with

chalcopyrite, tennantite, and sphalerite.

CHDH23-87 was drilled with an orientation of 315°/-75° to a depth of 850 metres:

 Significant Drill intercepts:

o 700.0m @ 0.23% Cu, 0.08 g/t Au, 5.47 g/t Ag, from 112m.

 Including 18.0m @ 1.77% Cu, 0.40 g/t Au, 101.2 g/t Ag, 0.32% Zn, from 112m.

 The above subinterval also includes 8.0m @ 2.06% Cu, 0.18 g/t Au, 42.3 g/t Ag,

and 0.25% Zn, from 443m.

 Geology:

o Medium-grained porphyritic dacite with a rgillic alteration and pyrophyllite in fractures ,

moderate sulphides (pyrite, chalcopyrite, sphalerite) and f ew fine HS veins. Highlights

included abundant Cu-Zn in a fracture zone (pyrite -chalcopyrite-tennantite-sphalerite +/-

galena). At depth, medium to fine grained porphyritic diorite with large, abundant quartz

eyes, moderate q uartz-sericite alteration and p yrophyllite in fracture fill and HS veins.

Highlight stockwork zone with 18-20 vein/metre frequency comprising B-A and molybdenite

veins. Abundant molybdenite in quartz veins, with early microveins associated with

chalcopyrite and digenite. Thin, zoned HS veins with chalcopyrite, sphalerite and

tennantite. Finely disseminated mineralization in cavity fills and veins. Moderate (5-7%)

sulphides comprising pyrite, chalcopyrite, digenite, and molybdenite. HS veins with

chalcopyrite and sphalerite increase in intensity near the bottom of the hole from 766 -

776m.

CHDH23-88 was drilled with an orientation of 315°/-75° to a depth of 801 metres:

 Significant Drill Intercepts:

o 715.0m @ 0.24% Cu, 0.11 g/t Au, and 4.92 g/t Ag, from 86.0m to end of hole, open at

depth.

 Including 34.0m @ 1.33% Cu, 0.71 g/t Au, and 6.13 g/t Ag, from 582.0 to 616.0m.

Chinchillones Target: MSA begins to outline in-fill drilling in its High-grade body with mineralization

extending up to 800m depth

MSA has begun to prepare an in -fill drilling program covering an area 1 ,550 m long by 1,200 m wide, for

the purpose of generating a mineral resource estimate on the Property. This area represents the primary

NNE-trending zone of mineralization within the Chinchillones Target, as delineated through drilling . See

Map 2.

Grid interval/hole spacing is currently set at approximately 150 m, and at least 70% of holes completed at

Chinchillones are anticipated to be included in the model. Drilling results so far have indicated continuity of

all metallic domains. The average depth of the planned drilling is approximately 685 m.

2023-11-20 - Minsud drilling and initiate MRE.docx

The initial program includes 25,000 metres of diamond drilling, distributed in 30 drillholes. This phase of

drilling is expected to be completed by mid-2024.

CHDH23-82 to CHDH23 -85 correspond to the "scouting” phase, while CHDH23 -86 to CHDH23 -90

correspond to the “in-fill” phase in the Chinchillones target.

New Targets

During the months of September and October, a survey of new areas on the south and west edges of the

Chita Valley property began. The objective is to develop new areas to drill by mid-2024. The survey included

surface geological mapping, sample collection for ASD Spectrometry, and a total of 300 rock chip samples.

The Company is currently awaiting laboratory results.

Ramiro Massa, Minsud ’s President & CEO, said: “Drilling at the Chinchillones Target on our Chita Valley

Project has yielded results beyond our initial expectations, demonstrating the Project's scale and potential

as significantly greater than previously anticipated. These findings have prompted us to commence an

updated mineral resource estimate on the project, which will now include the Chinchillones Target. The

updated mineral resource estimate will allow us to implement this zone as part of the project's future

development and overall value. As always, the Minsud te am is focused on advancing the Chita Valley

Project to its full potential.”

General outlook and exploration implications

The current results of the Phase IV exploratory activities, together with previous drilling phases, have

confirmed an expanded Chinchillones porphyry-epithermal system, now estimated to cover a minimum area

of 2 km x 2 km. The zone is open to more than 1,000m depth.

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.

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 s ulphide

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 development of its substantial mineral resource endowment.
