Minsud Resources Intersects 276m at 0.65% CuEq and 53m at 1.31% CuEq at the Chita Valley Project

2021-10-07 07:51:51

TORONTO, Oct. 7, 2021 /CNW/ – Minsud Resources Corp. (TSXV: MSR) (“Minsud” or the “Company”), is pleased to announce receipt of assay results from the additional seven (7) drill holes completed in the ongoing Phase 3 program over the Chinchillones area, located at the Chita Valley Project, San Juan province, Argentina. Encouraged by the results received, the Company and its partner, a subsidiary of South32 Limited (“South32“), have decided to extend this drilling program, with the aim of continuing exploring this recently discovered area, expecting to complete a total of 12,000 metres by the end of the year.

Nineteen (19) drill holes were completed to date this year encompassing a total of 8,600 metres, including three (3) new drill holes in other areas of the Chita Valley Project. Highlights are listed below, along with accompanying figures.

  • CHDH21-30 intersected 276m at 0.65% copper equivalent (“CuEq”), from 182m to 458m. (0.44% Cu, 0.11 g/t Au, 8.65 g/t Ag, 329 ppm Pb, 0.11% Zn). This drill hole is located 820m east of CHDH21-28, heading NNE, dipping 65° and drilled to 650m depth. This drill hole intersected mineralized cupriferous faults between 4m to 8m-wide, with grades up to 2.73% Cu. The main mineralization occurs as disseminations, and in thin quartz type “B” and “A” veinlets of pyrite-chalcopyrite and chalcopyrite-bornite, respectively. This drill hole probably confirms the presence of another Cu-Mo porphyry centre and is interpreted here to be open in several directions.

    The substantial porphyry Cu mineralization at CHDH21-30 confirms the potential of Chinchillones to host clusters of intrusion-hydrothermal phreatic breccias and centred porphyry mineralization.

  • CHDH21-28 intersected 53m at 1.31% CuEq from 584m (1.04% Cu, 0.18 g/t Au, 3.18 g/t Ag, 227 ppm Mo) including a higher-grade section of 29m at 2.07% CuEq from 608m (1.69% Cu, 0.30 g/t Au, 4.69 g/t Ag, 250 ppm Mo). This drill hole is located 150m south to the recently reported CHDH21-23, with SSE azimuth, dipping 65° and drilled to 687.7m depth. This drill hole intersected altered phreato-magmatic breccias down to 80m. Thence it went through intercalated Permian sediments and dacite bodies, both affected by intense argillic (illite –kaolin) alteration. The last 150m of this drill hole comprised a diorite porphyry hosting intense quartz-sericite alteration, cut by phreato hydrothermal breccias hosting high-grade IS (Intermediate sulphidation) Pb-Zn-Cu. The higher-grade mineralization occurs in a zone characterized by well-developed sulphide cemented phreato hydrothermal breccias and veins of sphalerite–chalcopyrite-galena, superimposed on a porphyry system.

    The diorite-hosted porphyry mineralization intersected at depth is thought to be same porphyry body found in drill hole CHDH21-23 (see Press Release dated August 26, 2021). These two drill holes, in conjunction with CHDH20-04 drilled in 2020, confirmed the presence of at least 400m-long, deep porphyry Cu-Mo system at Chinchillones.

  • CHDH21-26 intersected 106m at 0.74% CuEq from 192m to 298m (0.14% Cu, 0.11 g/t Au, 17.81 g/t Ag, 0.25% Pb, 0.91% Zn). It confirms the presence of high grade hydrothermal breccias at depth.
  • CHDH21-29 intersected 403m from 66m to 468m (end of hole), of anomalous Cu mineralization averaging 0.13% throughout the drill hole. The principal mineralization occurs as disseminations and in thin “A” type quartz veinlets hosted in dacitic rocks and in the phreatic hydrothermal breccia.

The drill hole results reported above confirm the presence of highly significant Zn-Pb-Ag mineralization that overprints at least two (2) porphyry centres.

Ramiro Massa, Minsud’s President & CEO, said: “The potential for a large-scale copper-moly porphyry system in the Chinchillones area remains open to the south and at depth. These results have created a great deal of excitement and expectation within the team, and we are currently reviewing the next steps with our partner South32. We believe that we have a unique opportunity at the Chita Valley Project.”

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, South32 will provide further funding to MSA over the next 3 years such that its aggregate funding is (i) not less than C$7 million by December 31, 2021; (ii) not less than C$10.5 million by December 31, 2022; and (iii) 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%.
