Minsud Resources Corp. encounters 555m at 0.43% Cu, 0.19 g/t Au, 4.80 g/t Ag

Since the commencement of the Earn-in agreement with South32 Aluminium (Holdings) Pty Ltd ("South32") a wholly owned subsidiary of South32 Limited, a total of ninety-eight (98) drillholes have been completed to date, encompassing 63,168 metres. Assay results have been received from drillholes CHDH23-91 through CHDH23-98, which total 5,883 metres.

In 2023, Minsud completed 25,986.4 metres of diamond drilling. Of this, 16,148.4 metres were from scout drilling and 9,838.0 metres were from the infill drilling program.

Key highlights and associated figures are provided below. Summary of drilling results is shown in Table 1. Drillhole locations are shown in Map 1. Documented alteration and mineralization are shown in Map 2.

CHDH23-96 was drilled with an orientation of 315°/-65° to a depth of 801 metres:

• Significant Drill Intercepts:
  • 555.0m @ 0.43% Cu, 0.19 g/t Au and 4.80 g/t Ag, from 246m depth.
    • including 44.0m @ 1.12% Cu, 0.29 g/t Au, 9.52 g/t Ag, from 462.0m depth.
• Geology:
  • The drillhole was comprised of intercalated phreatomagmatic breccias and fine to medium grained porphyritic dacite. Dominantly matrix-supported, polymictic, advanced argillic-altered dacitic breccias with prominent porphyritic dacite and quartzite clasts. Significant mineralization occurs as minute, frequent sulphide disseminations and in high sulphidation veins hosting up to 5% pyrite-bornite-sphalerite-tennantite. Narrow intervals of high sulphidation veins with more than 50% sulphides (pyrite-chalcopyrite-sphalerite-galena; e.g., 456-457m).
  • This higher-grade intercept shows potential continuity with the high-grade intercepts from CHDH23-73, CHDH22-62, CHDH23-69, CHDH23-77, CHDH22-57 and CHDH23-81, all of which exhibit similar Cu-Au geochemistry.
  • This important Cu-Au body is apparently aligned WNW and coincident with the eastern edge of a late dome-diatreme complex.
  • This higher-grade Cu-Au zone is surrounded by Cu-Au-As high sulphidation mineralization implying this Cu-Au porphyry mineralization is linked to the Cu-Au-As high sulphidation (HS) mineralization.

CHDH23-91 was drilled with an orientation of 315°/-75° to a depth of 850 metres:

• Significant Drill Intercepts:
  • 386.0m @ 0.27% Cu, 0.07 g/t Au and 3.19 g/t Ag, 200 ppm Mo, from 458.0m depth.
• Geology:
  • Up to 530.3m, dominantly intercalated, clast-supported, phreatomagmatic breccia. The breccia body hosts mineralized clasts of dacitic composition, quartzites and early dioritic porphyry. There are intervals with late silicification and high sulphidation veins. Strongly silicified zones host up to 5% sulphides (pyrite-tennantite-sphalerite-molybdenite-chalcopyrite). A medium grained tonalite porphyry was encountered from 530m hosting stockwork, B+A and Mo veins with up to 5-7% sulphides (pyrite-chalcopyrite-molybdenite-sphalerite).

CHDH23-95 was drilled with an orientation of 135°/-70° to a depth of 826 metres:

• Significant Drill Intercepts:
  • 194.0m @ 0.27% Cu, 0.03 g/t Au and 7.16 g/t Ag, 479 ppm Mo, 1858 ppm Zn, from 570.0m depth.
• Geology:
  • The drillhole was comprised of medium to fine grained, early dioritic porphyry. Moderate quartz-sericite alteration overprinted potassic alteration. There is a strong stockwork zone, with 20-25 vein/m frequency of B-type (with molybdenite) and A-type veins. Sulphides up to 3-5% (pyrite-chalcopyrite-molybdenite) occur as disseminations and in early quartz veins. Abundant chalcopyrite and molybdenite in quartz veins.

MSA continues the Chinchillones infill drilling program covering an area of approximately 2.5 square kilometres, for the purpose of generating a mineral resource estimate on the Property.

The program comprises 27,488 metres of diamond drilling, distributed in 32 drillholes. A total of 13 drillholes totaling 9,838 metres (CHDH23-86 to CHDH23-98) were completed by the end of December 2023. Grid interval/hole spacing is currently set at approximately 150 metres. The average depth of the planned drilling is approximately 800 metres. This phase of drilling is expected to be completed by the third quarter of 2024.

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 higher-grade Cu-Au body intersected from previously reported drillholes CHDH23-73 and CHDH23-62.

• Continue progress on the infill program, with remaining 17,650 metres, expected to be completed by third quarter.
• Outline the geometry of the high-grade Cu-Au body identified in CHDH22-62 through CHDH23-69 and CHDH23-96, associated with the eastern edge of the Dome.
• Continuation of metallurgical testing on representative domains. Establish high, medium, and low-grade domains for metallurgical and recovery testing. Establish degrees of impurities, contents, and processes in these domains.
• Continuation of mineralogical studies, Terraspec, TIMA, and QXRD on samples.
• Obtain an NI 43-101 resource estimate at the Chinchillones area within Chita Valley Project by the end of Q4.
• Beginning in Q4, continue with the development of new Exploration Targets identified during geological mapping surveys completed in 2023.

Ramiro Massa, Minsud's President & CEO, said: "Our ongoing drilling program focusing on the Chinchillones Target continues to prove to be highly successful in defining further mineralization. We look forward to continuing the program into 2024, towards the generation of an NI 43-101 mineral resource estimate on the project, following the completion of the program."

Table 1: Phase IV Diamond Drilling Program - Summary of Results

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.

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 sulphide 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.

Current exploration activities on the Chita Valley Project are being funded by South32 in accordance with the earn-in agreement between the parties entered into on November 1, 2019 as amended.
