Minsud Resources: Active Chita Valley Phase IV Drilling Further Confirms Second Porphyry Center at Chinchillones with 354m @ 0.29% Cu, 322ppm Mo, 0.10 g/t Au and 5.59 g/t Ag Open at Depth; with High-grade Mo-Re Intervals

2022-12-23 06:58:17

TORONTO, Dec. 23, 2022 /CNW/ – Minsud Resources Corp. (TSXV: MSR) (“Minsud” or the “Company”), is pleased to announce receipt of assay results from the additional nine (9) drillholes completed in the ongoing Phase IV scout drilling program at Chita Valley Project, San Juan province, Argentina.

Twenty-three (23) drillholes were completed to date this year, encompassing a total of 15,836m. Assay results have been received for additional nine (9) drill holes totaling 6,250m, which included drillholes CHDH22-51 through to CHDH22-59. There are six (6) drillholes still awaiting assay results.

The principal objectives of the current program include further down-dip and along strike delineation of the mineralized porphyries and affiliated host rocks discovered during the Phases I to III programs (2020 and 2021) and to test additional targets at Chinchillones and the nearby Link Zone area.

Highlights are listed below, along with the accompanying figures.

Chinchillones Second Porphyry Cu-Mo-Ag-Au

The recent drilling results further confirmed the presence of a second porphyry Cu-Mo-Au-Ag centre located around 450m east of the Chinchillones central porphyry and expressed on surface as prominent confluence of NS- and EW- trending ridges (see Figure 1) occupied by silicified and brecciated Permo-Carb Agua Negra Fm quartzose sandstone. This blind Cu-Mo-Ag-Au diorite porphyry is interpreted to be NE-elongated, at least 700m-long and 350m-wide. This new intrusion centre is transitional upward to a pervasive pyrophyllite-dominated advanced argillic alteration zone hosted in dominantly dacitic volcanics and breccias. The Chinchillones central porphyry occurs as roof pendants and angular clasts to the dacitic volcanics, providing unequivocal temporal separation between the two productive porphyries.

Significant porphyry Cu-Mo mineralization intervals for drillhole CHDH22-57:

  • 354m at 0.29% Cu, 322ppm Mo, 0.1 g/t Au and 5.59 g/t Ag from 484m (open at depth) including 50m at 0.25% Cu, 0.11 gpt Au, 2.02 gpt Ag, 1,117 ppm Mo and 0.23 ppm Re from 770m highlighting higher-grade molybdenum and coincident rhenium mineralization.

Affiliated to the second porphyry are near-surface, high sulfidation mineralized bodies characterized by pervasive sulfidic replacement of host rocks, massive sulfidic pods/lenses, pervasive sulfidic disseminations and sulfides in-filling hydrothermal breccia matrix. The sulfides comprise varying amounts of pyrite-chalcopyrite-covellite-tennantite-enargite-chalcocite-digenite-bornite-sphalerite-galena-calaverite.  

These sulfidic zones are highlighted in in drillhole CHDH22-59:

  • 144m at 0.37% Cu, 0.14 g/t Au and 7.98 g/t Ag from 28m, and 16m at 0.98% Cu, 0.38 g/t Au and 17.59 g/t Ag from 260m.

Importantly, CHDH22-59 has effectively established the strike and down-dip continuity of the near-surface Cu-Au-Ag bodies encountered at CHDH21-40 and CHDH22-43 (see press releases dated February 24 and October 13, 2022). CHDH21-40: 84m at 0.59% Cu, 0.24 g/t Au, 15.03 g/t Ag; CHDH22-43: 112m at 0.42%Cu, 0.1 g/t Au, and 9.80 g/t Ag).

Link Zone Target

The Link Zone target is the area located between South Porphyry “PSU” and Chinchillones. The scout drilling in this area confirms the presence of high-grade mineralized structures hosted in the sedimentary Agua Negra Fm and intrusive Tertiary domes. Drillholes CHDH22-52 and 53 show anomalous high sulfidation (“HS”) mineralization of Cu-Zn-Ag controlled by a trending NNE fault, cutting andesitic porphyry at depth.

Drillhole CHDH22-51 has been drilled to the limit of the area between the Chinchillones target and Link Zone. This drillhole intersected numerous HS structures and hydrothermal breccias of up to 5m-thick with high grade Cu-Zn-Ag+/-Au.

The drillholes completed at the Link zone confirmed a NNE-trending mineralized corridor which is sympathetic to the delineated mineralization corridors at Chinchillones. The Company plans to continue drilling this target area to confirm the presence of these mineralized intrusive bodies at depth.

General outlook and exploration implications

The current results of Phase IV exploratory activities, together with previous drilling phases, confirmed the expanded Chinchillones porphyry-epithermal system, is now thought to encompass at least 2kms x 2 kms, and is demonstrably open to more than 850m depth. Drilling has demonstrated superposed broad zones of polymetallic Zn-Pb-Cu-Au-Ag mineralization hosted in linear hydrothermal breccia bodies of both epithermal high sulfidation and intermediate sulfidation affinities and interpreted to be fed from at least two (2) porphyry centers.

Ramiro Massa, Minsud’s President & CEO, said: “This ongoing Phase IV drill program at Chita Valley Project, together with previously completed phases have successfully demonstrated the presence of at least two porphyry centers at the Chinchillones porphyry and epithermal system, and furthermore extended its mineralization in all directions encompassing at least 2 kms x 2 kms, remaining open at depth. We also identified the presence of Rhenium associated with high-grade Molybdenum. Congratulations to our team that has been drilling safely throughout the year including during the winter season.

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.  

Under the earn-in agreement and having given the Company notice of its intention to continue funding the Chita Valley Project, South32 will provide further funding to MSA such that its aggregate funding is not less than C$14 million by February 28, 2024. South32 has the right to withdraw at the end of each year.

If South32 exercises its earn-in right it may elect 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 by paying an additional C$14 million to Minsud, or by funding 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%.
