Minsud Resources Corp Announces the Receipt of Assay Results from Fifteen Additional Drillholes, Which Were Completed as Part of the Ongoing Phase IV Infill Program At the Chita Valley Project, San Juan Province, Argentina
Minsud Resources Corp. announced the receipt of assay results from fifteen (15) additional drillholes, which were completed as part of the ongoing Phase IV infill program at the Chita Valley Project, San Juan Province, Argentina. The infill drilling program is being carried out by Minera Sud Argentina S.A. ("MSA"), a joint venture between a wholly owned subsidiary of South32 Limited ("South32") (50.1%) and a wholly owned subsidiary of Minsud Resources Corp. ("Minsud") (49.9%). The program covers approximately 2.5 square kilometres over the Chinchillones target, for the purpose of generating a maiden Mineral Resource Estimate. Since February 2024, continued drilling in Phase IV has been primarily concentrated in the SW-NE corridor at the eastern end of the Chinchillones target. To date, MSA has completed 15,796m in 25 drillholes, including up to hole CHDH24-124. An additional 3 drillholes, totaling 1,450m, are still pending completion to finalize the infill program. Assays have been received for drillholes CHDH24-104 to CHDH24-118, totaling 9,113.50m. CHDH24-117 was drilled with an orientation of 315°/-75° to a depth of 669.0m: Significant Drill Intercepts: 526.0m @ 0.33% Cu, 0.19 g/t Au, 16.11 g/t Ag, and 0.38% Zn, from 140m depth. including 29.0m @ 0.84% Cu, 0.27 g/t Au, 129.38 g/t Ag, and 1.75% Zn, from 209.0m depth. Including 17.0m @ 0.68% Cu, 0.55 g/t Au, 40.87g/t Ag, and 2.51% Zn, from 275.0m depth. Including 16.0m @ 1.24% Cu, 0.27 g/t Au, 6.16 g/t Ag, from 554.0m depth. Geology: This drillhole, located in the same section as CHDH22-62, CHDH23-73, and CHDH23-96, traverses the central and southeastern edge of the project. Up to a depth of 614m, it intersects phreatomagmatic and hydrothermal breccias with a dacitic matrix and polymictic/polymodal fragments with some small intercalations of Dacitic porphyry and Porphyry andesite. The alteration is predominantly moderate phyllic with advanced argillic overprinting. Sulphides are present at 5-7%, including pyrite, sphalerite, galena and +/- chalcopyrite. From 207.7 to 238.0m, high-grade hydrothermal breccia is encountered with 8-10% sulphides, including pyrite, sphalerite, galena, chalcopyrite, and tennantite. Below 614m, the drillhole intersects dacitic porphyry exhibiting moderate phyllic alteration and pervasive silicification overprinted. Abundant mineralization finely disseminated, cavity fills, and microveins. Sulphide content is around 5%, with pyrite, chalcopyrite, and chalcocite. Mineralization decreases towards the end of the interval. This intercept suggests the potential continuity of higher-grade mineralization, similar to that in CHDH22-62, CHDH23-73, and CHDH23-96, with Cu-Zn-As mineralization aligned NE along the eastern edge of the Dome. CHDH24-113 was drilled with an orientation of 315°/-75° to a depth of 650.0m: Significant Drill Intercepts: 448.0m @ 0.28% Cu, 4.31 g/t Ag, 14 ppm Mo, from 158.0m depth. including 4.0m @ 4.20% Cu, 0.39 g/t Au, 104.28 g/t Ag, and 1.34% Zn, from 159m depth. Geology: The drill hole is located southeast of CHDH24-116 and CHDH23-84, at distances of 116m and 84m, respectively. It intersects a phreatomagmatic breccia with a matrix-supported intercalated with dacitic porphyry dikes up to 126.0m. This breccia contains a dacitic matrix with fragments of quartzite, andesite, and dacitic porphyry, showing moderate advanced argillic alteration. Sulphides, mainly pyrite (2%), are present in the matrix and fragments, but no veins are observed. From 126.0m, the drill hole intersects medium-grained dacitic porphyry with abundant quartz eyes, exhibiting moderate phyllic alteration and occasional advanced argillic alteration. Up to 7% sulphides are present, predominantly pyrite, with minor tennantite and chalcopyrite. Notable high-sulphidation veins with up to 50% sulphides (pyrite, tennantite, sphalerite, galena, and chalcopyrite) are observed between 225.0-228.0m and 364-370m, with high-grade copper mineralization extending deeper. Sectors with high-grade Cu mineralization, both disseminated and in stockwork, remain open at depth. CHDH24-106 was drilled with an orientation of 135°/-80° to a depth of 851.0m: Significant Drill Intercepts: 325.0m @ 0.16% Cu, 698 ppm Mo, and 0.13 ppm Re, from 526m depth. Including 93.0m @ 0.09% Cu, 1292 ppm Mo, and 0.24 ppm Re, from 758.0m depth. Geology: This drillhole intersects a body of early dioritic porphyry, with strong B veins and UST -type veins, with dominant molybdenum (Mo) mineralization. This Mo mineralization is accompanied with anomalous values of Re, which increase at depth. MSA is continuing the Chinchillones infill drilling program over a 2.5 square kilometres area to generate a maiden Mineral Resource Estimate for the property. Since the start of the Earn-in Agreement, now a joint venture with South32, a total of one hundred twenty-four (124) drill holes, covering 79,148m, have been completed up to hole CHDH24-124. The infill drilling program comprises 27,084m of diamond drilling, distributed across 41 drillholes. A total of 13 drillholes totaling 9,838m (CHDH23-86 to CHDH23-98) were completed by the end of 2023. An additional 26 drillholes, totaling 16,196.60m, have been completed as of the date of this release. This brings the total to 26,034m completed to date in the Phase IV infill program. The grid interval/hole spacing is currently set at approximately 100-150m, with the average depth of the planned drilling at approximately 800m.
