TORONTO, Dec. 13, 2021 /CNW/ - Minsud Resources Corp. (TSXV: MSR) ("Minsud" or the "Company"), is pleased to announce receipt of assay results from the additional eight (8) drillholes completed in the ongoing Phase 3 program over the Chinchillones area, located at the Chita Valley Project, San Juan province, Argentina. The Company is completing the largest annual drilling program over the Chita project area, encompassing approximately 12,000 meters by the end of December 2021.
A total of twenty-four (24) drillholes are being completed by the end of this year. Twenty (20) drillholes have been reported through several previous press releases with remaining four (4) drillholes awaiting assay results.
Highlights are listed below, along with the accompanying figures. Scout drillholes CHDH21-33 to CHDH21-35 were drilled outside of the principal Chinchillones area.
CHDH21-37 is the deepest drillhole of the project with 852 m depth. The most significant intercepts included 448m with 1.20% CuEq; 3.59% ZnEq, from 404m to 852m EOH (0.29% Cu, 0.13 g/t Au, 24.08 g/t Ag, 353 ppm Mo, 0.27% Pb, 1.17% Zn) and a higher-grade zone of 114m from 490m at 2.67% CuEq; 8.00% ZnEq (0.52% Cu, 0.34 g/t Au, 67.30 g/t Ag, 0.79% Pb, 3.46% Zn).
This drillhole, with a NNW azimuth, dipping 80°, aimed at testing the extent of high-grade polymetallic mineralization intersected at CHDH21-23 (please see press release dated August 26, 2021). High-grade intervals are hosted in magmatic-hydrothermal breccias from 409m to 600m, with abundant sulphides in the breccia matrix. The breccia progresses at depth to a finer-grained dioritic porphyry containing pervasive Cu-Mo mineralization within type "B" veins, accompanied by strong sericite-quartz-pyrite alteration, until the end of the drillhole.
The mineralized diorites intercepted at depth in CHDH21-37, together with those observed in drillholes CHDH21-23, 28, 04 and 38, confirmed the presence of a porphyry mineralized body, from around 500m below surface extending down-dip to at least 850m. From the drilling conducted so far, the apparent NS-trending porphyry body is at least 500m-long and 270m-wide.
The higher-grade polymetallic mineralization from 102m occurs in a zone characterized by well-developed sulphide-cemented hydrothermal breccias and high-density vein network of sphalerite– chalcopyrite-galena-pyrargyrite-tennantite-native silver which is demonstrably superimposed on the Cu-Mo-Ag-Au porphyry body.
CHDH21-38 intersected 387m at 0.50% CuEq, from 340m to 727m. (0.25% Cu, 0.06 g/t Au, 9.06 g/t Ag, 111 ppm Mo). This drillhole is located 250m NE of CHDH21-37, heading S, dipping 75° with 727m depth. This drillhole intersected mineralized dacitic and dioritic rocks. The principal Cu-Mo-Ag-Au mineralization occur as disseminations, and in thin quartz type "B" and "A" veinlets of pyrite-chalcopyrite and chalcopyrite-bornite. In conjunction with drillhole CHDH21-37 these drillholes confirmed the presence of Cu-Mo porphyry at depth and demonstrate that the porphyry body is open in various directions. Molybdenum values remarkably increased through to the end of the drillhole, indicating further potential at depth.
The substantial and high-grade Zn-Pb-Ag-Cu-Au and Cu-Mo-Ag-Au mineralization at CHDH21-37 and CHDH21-38 confirm the potential of Chinchillones to host high-grade polymetallic mineralization transitioning to prospective cluster of porphyry Cu centres.
Ramiro Massa, Minsud's President & CEO, commented: "We continue to be excited and encouraged by results from our ongoing Phase 3 drilling program. This year we discovered a new porphyry center at Chinchillones area with Cu-Mo mineralization overprinted by a hydrothermal system Zn-Pb-Cu-Ag-Au. Our exploration program has expanded our understanding of the project and dramatically increased its potential. We continue our ongoing exploration program and anticipate further encouraging results with support from our partner South32".

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 sulfide 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 in accordance with the earn-in agreement between the parties entered into on November 1, 2019.
The earn-in agreement grants to South32 the right to acquire a 50.1% direct interest in the Company's Argentinean operating subsidiary Minera Sud Argentina S.A. ("MSA") at the end of the earn-in period. Under the earn-in agreement, and having given the Company notice of its intention to continue funding Chita Valley Project, South32 will provide further funding to MSA over the next 2 years such that its aggregate funding is (i) not less than C$10.5 million by December 31, 2022; and (ii) not less than C$14 million by December 31, 2023. South32 has the right to withdraw at the end of each year.
If South32 exercises its earn-in right it may elect to fund a pre-feasibility study, with a minimum spend of C$41 million, which would entitle it to elect to increase its 50.1% direct interest in MSA to 70%.
