Minsud encounters 526.0m at 0.33% Cu, 16.11 g/t Ag, and 0.38% Zn, including

29.0m at 0.84% Cu, 0.27 g/t Au, 129.38 g/t Ag, and 1.75% Zn at Chinchillones

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

to announce the receipt of assay results from fifteen (15) additional drillholes, which were completed as

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

The infill drilling program is being carried out by Minera Sud Argentina S.A. (“MSA”), a joint venture between

a wholly owned subsidiary of South32 Limited (“South32”) (50.1%) and a wholly owned subsidiary of Minsud

Resources Corp. (“Minsud”) (49.9%). The program covers approximately 2.5 square kilometres over the

Chinchillones target, for the purpose of generating a maiden Mineral Resource Estimate.

Since February 2024, continued drilling in Phase IV has been primarily concentrated in the SW-NE corridor

at the eastern end of the Chinchillones target. To date, MSA has completed 15,796m in 25 drillholes,

including up to hole CHDH24-124. An additional 3 drillholes, totaling 1,450m, are still pending completion

to finalize the infill program. Assays have been received for drillholes CHDH24-104 to CHDH24-118, totaling

9,113.50m, and are reported below.

Key highlights and associated figures are provided below. Summary of drilling results is shown in Table 1.

Drillhole locations are shown in Map 1. A long section with the best intercepts in the recent holes is shown

in Map 2.

CHDH24-117 was drilled with an orientation of 315°/-75° to a depth of 669.0m:

• Significant Drill Intercepts:

▪ 526.0m @ 0.33% Cu, 0.19 g/t Au, 16.11 g/t Ag, and 0.38% Zn, from 140m depth.

▪ including 29.0m @ 0.84% Cu, 0.27 g/t Au, 129.38 g/t Ag, and 1.75% Zn, from 209.0m

depth.

▪ Including 17.0m @ 0.68% Cu, 0.55 g/t Au, 40.87g/t Ag, and 2.51% Zn, from 275.0m depth.

▪ Including 16.0m @ 1.24% Cu, 0.27 g/t Au, 6.16 g/t Ag, from 554.0m depth.

• Geology:

o This drillhole, located in the same section as CHDH22 -62, CHDH23 -73, and CHDH23 -96,

traverses the central and southeastern edge of the project. Up to a depth of 614m, it intersects

phreatomagmatic and hydrothermal breccias with a dacitic matrix and polymictic/polymodal

fragments with some small intercalations of Dacitic porphyry and Porphyry andesite . The

alteration is predominantly moderate phyllic with advanced argillic overprinting. Sulphides are

present at 5 -7%, including pyrite, sphalerite, galena and +/- chalcopyrite. From 207.7 to

238.0m, high -grade hydrothermal breccia is encountered with 8 -10% sul phides, including

pyrite, sphalerite, galena, chalcopyrite, and tennantite.

o Below 614m, the drillhole intersects dacitic porphyry exhibiting moderate phyllic alteration and

pervasive silicification overprinted. Abundant mineralization finely disseminated, cavity fills, and

microveins. Sul phide content is around 5%, with pyrite, chalcopyrite, and chalcocite.

Mineralization decreases towards the end of the interval.

o This intercept suggests the potential continuity of higher-grade mineralization, similar to that in

CHDH22-62, CHDH23-73, and CHDH23 -96, with Cu -Zn-As mineralization aligned NE along

the eastern edge of the Dome.

CHDH24-113 was drilled with an orientation of 315°/-75° to a depth of 650.0m:

• Significant Drill Intercepts:

▪ 448.0m @ 0.28% Cu, 4.31 g/t Ag, 14 ppm Mo, from 158.0m depth.

▪ including 4.0m @ 4.20% Cu, 0.39 g/t Au, 104.28 g/t Ag, and 1.34% Zn, from 159m depth.

• Geology:

o The drill hole is located southeast of CHDH24-116 and CHDH23-84, at distances of 116m and

84m, respectively. It intersects a phreatomagmatic breccia with a matrix-supported intercalated

with dacitic porphyry dikes up to 126.0m. This breccia contains a dacitic matrix with fragments

of quartzite, andesite, and dacitic porphyry, showing moderate advanced argillic alteration.

Sulphides, mainly pyrite (2%), are present in the matrix and fragments, but no veins are

observed.

o From 126.0m, the drill hole intersects medium -grained dacitic porphyry with abundant quartz

eyes, exhibiting moderate phyllic alteration and occasional advanced argillic alteration. Up to

7% sul phides are present, predominantly pyrite, with minor tennantite and chalcopyrite.

Notable high-sulphidation veins with up to 50% sulphides (pyrite, tennantite, sphalerite, galena,

and chalcopyrite) are observed between 225.0-228.0m and 364-370m, with high-grade copper

mineralization extending deeper. Sectors with high-grade Cu mineralization, both disseminated

and in stockwork, remain open at depth.

CHDH24-106 was drilled with an orientation of 135°/-80° to a depth of 851.0m:

• Significant Drill Intercepts:

▪ 325.0m @ 0.16% Cu, 698 ppm Mo, and 0.13 ppm Re, from 526m depth.

▪ Including 93.0m @ 0.09% Cu, 1292 ppm Mo, and 0.24 ppm Re, from 758.0m depth.

• Geology:

o This drillhole intersects a body of early dioritic porphy ry, with strong B veins and UST -type

veins, with dominant molybdenum (Mo) mineralization. This Mo mineralization is accompanied

with anomalous values of Re, which increase at depth.

Chinchillones Infill Drilling Program Update

MSA is continuing the Chinchillones infill drilling program over a 2.5 square kilometres area to generate a

maiden Mineral Resource Estimate for the property. Since the start of the Earn -in Agreement, now a joint

venture with South32, a total of one hundred twenty-four (124) drill holes, covering 79,148 m, have been

completed up to hole CHDH24-124.

The infill drilling program comprises 27,084m of diamond drilling, distributed across 41 drillholes. A total of

13 drillholes totaling 9,838 m (CHDH23-86 to CHDH23 -98) were completed by the end of 2023 . An

additional 26 drillholes, totaling 16,196.60m, have been completed as of the date of this release. This brings

the total to 26,034m completed to date in the Phase IV infill program . The grid interval/hole spacing is

currently set at approximately 100-150m, with the average depth of the planned drilling at approximately

800m.

Ongoing 2024 Roadmap Items:

(1) Flotation metallurgical testing at ALS Kamloops is ongoing. These metallurgical tests are a

prerequisite for a maiden Mineral R esource Estimate on the Chinchillones polymetallic deposit

discovery.

(2) Terraspec, TIMA, micro -XRF, and QXRD mineralogical studies have been completed on

representative samples from the 2023 drillholes , with ongoing data collection for drilling

carried out in 2024.

(3) Continuation of the remainder of the infill program of approximately 17,650 m, expected to be

completed by Q3 2024.

(4) Beginning in Q4 2024, progressing with new Exploration Targets identified during geological

mapping surveys completed in 2023.

(5) Completion of an NI 43-101 maiden Mineral Resource Estimate for the Chinchillones deposit within

the Chita Valley Project by the end of Q4 2024.

Ramiro Massa, president & CEO of Minsud, said: “ Our team remains committed to advancing the project

through a comprehensive exploration program, focusing on identifying and delineating high-grade mineral

zones. We are expecting our strategic approach to deliver tangible results and position the Chita Valley

Project as a leading exploration asset within the province of San Juan. We will continue to provide regular

updates on our progress as we work towards achieving our goal of establishing a robust mineral resource

estimate. We are excited about the futu re of the Chita Valley Project and its potential to contribute to our
