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

20.11.2023  |  CNW
Including 18m at 0.95% Cu, 0.21 g/t Au and 10.06 g/t Ag at Chinchillones, Plans Mineral Resource Estimate

TORONTO, Nov. 20, 2023 - Minsud Resources Corp. (TSXV: 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 HSE Target NNE: High-grade body with mineralization 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:
    • 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:
    • The drillhole was comprised of intercalated phreatomagmatic breccia and fine to medium grained porphyritic dacite, with moderate to strong advanced argillic alteration with pyrophyllite and kaolinite. Few local pyrite veins with moderate (3-5%) disseminated chalcopyrite, chalcocite, and pyrite. 5 to 10 cm HS veins between 380 to 400m with chalcopyrite, tennantite, and sphalerite.

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

  • Significant Drill intercepts:
    • 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:
    • Medium-grained porphyritic dacite with argillic alteration and pyrophyllite in fractures, moderate sulphides (pyrite, chalcopyrite, sphalerite) and few 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 quartz-sericite alteration and pyrophyllite 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:
    • 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.
  • Geology:
    Intercalated, fine- to medium-grained porphyritic dacite. Moderate to strong quartz-sericite alteration and pervasive silicification. Abundant, finely disseminated mineralization, in addition to cavity fills and microveins. Moderate pyrite and chalcopyrite. From 746m, medium-grained porphyritic diorite with moderate chloritic/sericitic alteration and advanced argillic alteration in fractures and veins. Moderate frequency A+B veins, molybdenite veins and HS veins. Moderate (3-5%) sulphides, dominantly pyrite with chalcopyrite, sphalerite, tennantite and molybdenite, finely disseminated and in early vein mineralization.

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.

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 team 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.

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 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 a subsidiary of South32 Limited ("South32") in accordance with the earn-in agreement between the parties entered into on November 1, 2019 and amendments.
