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.

and 0.25% Zn, from 443m.
Geology:

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%)

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.
