Arizona Tribune - Algo Grande Launches Advanced Geophysical and Geochemical Programs Ahead of Phase II Drilling in Q2 2026

The integrated exploration campaign includes:

• High-resolution LiDAR survey (license wide)

• Drone-based magnetic survey

• Systematic soil geochemical sampling program

These programs include a high-resolution LiDAR survey to refine structural interpretation and identify subtle topographic and alteration features, a drone-based magnetic survey designed to map intrusive contacts and magnetite-rich skarn bodies, and the launch of a systematic geochemical soil sampling program across a newly identified area within the Cerro Grande target zone. Together, these datasets are expected to significantly enhance drill targeting and expand the known footprint of mineralization across the district-scale Adelita property.

Enrico Gay, CEO of Algo Grande, stated: "Following the success of our maiden drill program, our focus is now on systematically scaling the Adelita system. The drone magnetic survey is particularly important, as it allows us to map magnetite-rich skarn horizons along strike and target step-outs beyond the currently defined 300-metre zone at Cerro Grande. Equally, the LiDAR survey is critical in what we interpret to be a structurally controlled system, as it will enhance our ability to identify and track the key structures responsible for mineralization. Together, these datasets position us to define high-confidence drill targets as we advance toward our Phase II drill program in Q2 2026."

The resulting structural, geophysical, and geochemical datasets will be integrated into the Company's 3D geological and machine-learning targeting models to optimize drill hole placement and maximize discovery potential.

LiDAR Survey

The Company has initiated a high-resolution airborne LiDAR survey across the entire Adelita property.

The LiDAR program is designed to:

• Define structural corridors and fault systems controlling mineralization

• Identify subtle alteration signatures and mineralized trends beneath cover

• Detect historical workings and previously unrecognized exploration targets

This dataset will provide a high-precision structural framework critical to targeting both skarn-hosted mineralization and potential feeder systems at depth.

Drone Magnetic Survey

Algo Grande has launched a high-resolution drone-based magnetic survey over the +6km mineralization prospective corridor and surrounding targets.

The survey is designed to:

• Map intrusive contacts associated with mineralizing systems

• Identify magnetite-rich skarn bodies linked to copper mineralization

• Delineate structural controls and potential feeder zones associated with copper-gold-silver mineralization (Figure 1)

Drone magnetics provide significantly higher resolution than legacy datasets and are expected to play a key role in identifying buried skarn bodies and vectors toward a potential porphyry source at depth, supporting definition of the Company's planned drilling campaign scheduled to commence in Q2 2026.

Geochemical Soil Sampling

A systematic soil grid program will be conducted over an area where recent mineralization was identified and where limited historical geochemical coverage exists (Figure 2). The objective is to better understand the provenance of a mineralized granodiorite sample (Figure 3) collected in early January and to prioritize follow-up trenching and drilling across defined anomalies.

The mineralized granodiorite boulder was encountered at approximately one metre depth during access construction for drilling activities.

These integrated datasets are expected to significantly enhance drill targeting for the next phase of exploration.

About Algo Grande Copper Corp.

Algo Grande Copper Corp. is a growth-focused mineral exploration company advancing the Adelita Project, a district-scale, multi-system copper-gold-silver opportunity positioned in the prolific Arizona-Sonora copper belt.

The company is dedicated to unlocking the full mineral potential of this under-explored corridor through disciplined data-driven exploration, technical excellence, and a firm commitment to value creation for shareholders. The 5,895-hectare Adelita Project is anchored by the high-grade Cerro Grande Cu-Au-Ag skarn discovery, which exhibits strong continuity along a defined corridor extending over 6 kilometers. Reprocessing of legacy geophysical data and field mapping indicate the presence of a potential porphyry system at depth, suggesting a classic skarn-porphyry mineralization model similar to major deposits found throughout northwestern Mexico.
