Chita South Porphyry (PSU) Drilling Results Received
None
On November 4, 2025, Minsud Resources announced the receipt of drilling results from its completed 15-hole, 5,490.2-meter diamond drilling program at the Chita South Porphyry (PSU) deposit, part of the Chita Valley Project in Argentina. The press release highlights numerous mineralized intervals, however, it only provides assay values for gold (Au).
Notable intercepts mentioned include: - A high-grade polymetallic vein in hole PSUDH25-162: 3.1 meters grading 4.66 g/t Au. - Several long intercepts of very low-grade gold, such as 122 meters of 0.03 g/t Au in hole PSUDH25-159 and 270 meters of 0.08 g/t Au in hole PSUDH25-169.
The comments in the data tables reference "Mo-Cu mineralization" and "supergene-enriched" zones, but no corresponding copper (Cu) or molybdenum (Mo) grades are provided in the release.
This news is materially negative. The drilling program at PSU was a significant undertaking with the stated goal (from the July 29, 2025 news release) of "Expanding and in-filling the supergene-enriched, open-pittable PSU historical resource base." The PSU deposit is known as a copper-molybdenum-gold porphyry system, where copper and molybdenum are the primary economic drivers.
The key issues with this release are: 1. Omission of Key Data: The complete absence of copper and molybdenum grades is a major red flag. As critical analysts, we must assume that information is presented in the best possible light. Omitting the primary metals for a porphyry deposit strongly implies that the grades were not significant or economically relevant. This practice of selective disclosure is highly concerning. 2. Failure to Meet Expectations: The market and investors were anticipating results that would add tonnes and/or grade to the existing PSU resource. The July 29, 2025 scout drilling results at PSU included intercepts like 120 meters of 0.21% Cu and 77 ppm Mo. The current release, with only negligible gold grades reported, fails to demonstrate continuity or expansion of that type of mineralization. 3. Context of Stock Performance: The stock price rallied over 80% from a low of $0.40 in early October to $0.72 leading into this news, indicating high market expectations for these drill results. These results do not justify that rally and leave the stock vulnerable to a significant correction.
In conclusion, the results from this major drill program appear to have failed to achieve their primary objective. The lack of transparency regarding Cu and Mo grades suggests the program was unsuccessful in expanding the core of the PSU deposit, making this a material negative event for the company.
Minsud Resources Corp. is a Canadian exploration company focused on its Chita Valley Project in the San Juan province of Argentina. The project is a joint venture held by Minera Sud Argentina S.A. (MSA), in which Minsud holds a 49.9% interest and global mining company South32 Limited holds the remaining 50.1% and acts as the project operator. The Chita Valley Project is a large, exploration-stage porphyry-epithermal system hosting two principal deposits: the Chinchillones polymetallic (Cu-Ag-Au-Zn-Pb) deposit and the PSU porphyry (Cu-Mo-Au) deposit. In January 2025, the company announced a large maiden mineral resource for Chinchillones, totaling over 760 million tonnes in the indicated and inferred categories.
