Algo Grande Accelerates Phase II Drilling at Adelita After UAV Magnetics Identify Multiple Porphyry Targets
At a glance
- High-resolution UAV magnetics refined target geometry at Adelita, revealing discrete magnetic highs consistent with multiple stacked skarn/porphyry centres along a 6.5 km corridor.
- Phase II drill program: approximately 8,000 metres planned across 21 holes; Hole 002 is underway and a second rig will be added to accelerate completion.
- Priority targets include Cerro Grande (skarn expansion), Cerro Potrero South, Las Trancas (epithermal), La Corona (new untested intrusion with surface samples up to 2% Cu), and Mezquital (large Mo signature >2 km).
- First assay results from the Phase II campaign are expected in August 2026 and will be a near-term catalyst.
- While geophysics improves targeting, drilling and assays are required to confirm porphyry-skarn mineralisation and the projects commercial potential.
Project Update: Adelita
Algo Grande Copper is accelerating its exploration at the Adelita project in Sonora, Mexico, after high-resolution UAV magnetic surveying identified multiple porphyry-related intrusive centers at depth. The company has advanced its Phase II drill program ahead of schedule: the campaign now comprises roughly 8,000 metres over 21 planned holes, with the second hole already being drilled and a second drill rig due to be mobilized to speed completion. Management expects first assay results in August 2026.
The ongoing campaign focuses primarily on expanding the Cerro Grande skarn, with additional holes planned to test Cerro Potrero South and the epithermal target Las Trancas. Most metres in the Phase II program are allocated to stepping out and infilling around Cerro Grande to define extensions of the known high-grade skarn mineralisation.
Geophysics and Targets
New, high-resolution drone magnetics and 3D modelling have reshaped the geological picture at Adelita. What earlier VTEM surveys portrayed as a single broad anomaly along the Cerro Grande corridor now resolves into a series of discrete, elongated magnetic highs. That pattern is consistent with multiple stacked skarn bodies or intrusive centers along a roughly 6.5-kilometre structural corridor, several of which remain untested by drilling.
Three primary target areas have been defined by the 3D models as plausible sources for the surface copper-silver-gold mineralization. In addition to a deeper center beneath the high-grade Cerro Grande skarn, the survey identified La Corona, a previously untested intrusion that correlates at surface with strong copper anomalies and historic rock samples up to 2% copper. The largest magnetic anomaly on the concession sits at Mezquital, where a significant molybdenum signature suggests a potential mineralized body extending for over two kilometres.
The current drill program is designed to test these geophysical targets at depth and to confirm whether the magnetic anomalies correspond to porphyry-style mineralization or stacked skarn systems. If the models hold up in drill core, Adelitas prospectivity for copper-gold discoveries would be materially enhanced.
What This Means for Investors
Algo Grande Copper (TSX-V: ALGR; OTC: ALGRF; FRA: KM00) is moving quickly to convert the improved geophysical targeting into subsurface data. Accelerating the drill pace with a second rig and focusing most metres on Cerro Grande aims to deliver timely results that will clarify the scale and style of mineralisation at Adelita. First assays due in August 2026 will be a key near-term catalyst for the story.
Investors should note that airborne magnetics and 3D models sharpen targeting but do not replace drill confirmation; the upcoming assay results and geological logging will be decisive in testing the porphyry-skarn interpretation.
Conclusion
The combination of high-resolution UAV magnetics and an expedited Phase II drilling program positions Adelita as a more clearly defined exploration opportunity. With multiple untested magnetic highs, a newly identified intrusive at La Corona, and a large molybdenum-associated anomaly at Mezquital, Algo Grande has several priority targets to test. The market will be watching the August 2026 assay timeline closely as the company seeks to validate its multizonal porphyry-skarn model and de-risk the projects potential for a meaningful copper-gold discovery.
