Algo Grande Copper Core Testing Shows Mineralized Skarn is Denser and More Chargeable Than Host Rocks; Ground Gravity Survey to Begin at Adelita

Laboratory testing of 18 Cerro Grande drill-core samples found mineralized skarn averaged 3.76 g/cm³ in density, versus 2.92 g/cm³ or less for tested host rocks, and had chargeabilities of 74–128 ms versus 3–8 ms for unmineralized skarn. A ground gravity survey is scheduled to begin October 22, 2026, covering approximately 1,296 stations across Mezquital, Cerro Grande, Cerro Potrero and Las Trancas; results will be integrated with the company’s magnetic, IP/MT, petrophysical and drilling data.

Analysis

The useful signal is methodological, not yet economic: combining gravity with existing geophysical and drilling datasets could improve target ranking and reduce wasted follow-up drilling if the density contrast is spatially coherent. It does not establish continuity, grade, tonnage, recoverability, or a mineable resource. The key uncertainty is whether the measured properties from a small set of selected cores represent the broader system; gravity responses are also non-unique and depend on body geometry and depth.

Near term, the survey start is a modest execution catalyst, but absent a supplied company identity, ticker, funding profile, or metal exposure, there is no defensible security-level valuation or commodity read-through. Over 1–3 months, the investable catalyst is interpreted survey results tied to drill targets—not station count or technical language. Over 6–18 months, value creation would require follow-up drilling to validate targets and demonstrate scale and grade. Delays, ambiguous anomalies, or unsuccessful drilling could reverse any speculative rerating; stronger evidence would be coherent anomalies followed by reproducible drill intersections.

Key Decisions for Investors

• No immediate directional trade: the information is pre-resource exploration evidence and lacks a mapped issuer or ticker. Do not infer exposure to a specific metal or listed company.
• Put the survey interpretation and subsequent drill program on a watchlist. Reassess only when the issuer, target geometry, assay results, and planned follow-up are disclosed.
• Before underwriting any exploration position, verify cash runway, expected drilling spend, permitting status, and whether the gravity targets are independently supported by geochemistry and drilling; these determine dilution and execution risk.
• Falsify the positive targeting thesis if results are diffuse or inconsistent with existing datasets, or if follow-up drilling fails to confirm mineralization; treat a coherent anomaly as a catalyst to investigate, not proof of economic value.
