Minsud Resources Corp. announced receipt of assay results from fifteen (15) additional drill holes completed in the recently finalized in-fill and selective peripheral diamond drilling campaign at the supergene-enriched Chita South Porphyry (PSU) Cu-Mo-Au deposit, part of the Chita Valley Project in San Juan province.
By Panorama Minero
The shallow drilling program comprised nineteen (19) diamond drill holes (average depth of 289m) totalling 5490.2 meters. PSU is just two kilometers east from the recently discovered Chinchillones polymetallic deposit, which hosts an indicated resource of 188Mt @ 025% Cu (copper), 0.11 g/t Au (gold), 10.6 g/t Ag (silver), 36 ppm Mo (molybdenum) and 0.16% Zn (zinc) and an inferred resource of 573 Mt @ 022% Cu, 0.09 g/t Au, 9.0 g/t Ag, 93 ppm Mo and 0.11% Zn.

The largely immature supergene-enriched zone extends 1.2kms x 1.1kms. It is characterised by the presence of chalcocite-digenite and covellite in quartz-sulfide veins/veinlets and as multitudes of minute disseminations. The supergene-enriched domain ranges from 10 to 150m thick.
-
The leached capping is up to 50m thick and consists of variable amounts of hematite, goethite and jarosite with minor supergene copper minerals.
-
The supergene clays, (kaolinite, illite and smectite and iron sulfates) make up less than 5 vol% of rock; the subdued supergene clay content contributes to the high copper recoveries (>80%, up to 95%) achieved in the metallurgical leaching tests and sequential copper analyses.
Next Steps include:
-
Re-estimation of the PSU resource, using updated grade and metal price protocols.
-
A large-scale MT survey over 13,5kms x 8.0kms area covering all the principal target areas and surroundings, over Chita North and Fortuna I properties.
-
AI-supported targeting exercise in collaboration with the MSA technical team.
-
Detailed geological mapping and expanded geochemical surveys in the Romina and Chinchillones corridors.
-
Identification and refinement of additional drill-ready targets through integrated geology-geochemical and geophysical surveys.
The Chita Valley Project is a large exploration stage porphyry system with widespread porphyry style Cu-Mo-Au and polymetallic Ag-Pb-Zn mineralization hosted in multi-phased intrusions and country rocks with affiliated hydrothermal breccias. San Juan Province has a robust mining sector and recognizes the important economic benefits of responsible development of its substantial mineral resource endowment. The Chita Valley Project is owned and managed by MSA, of which Minsud indirectly holds a 49.9% interest. The other 50.1% interest in MSA is owned by a wholly owned subsidiary of South32 Limited. Minsud and South32 entered into a shareholders’ agreement to govern the management and operation of MSA which will include further exploration.
