Algo Grande Launches Advanced Geophysical and Geochemical

Programs Ahead of Phase II Drilling in Q2 2026

Vancouver, BC – March 19, 2026 – Algo Grande Copper Corp. (TSX-V: ALGR |

OTC: KNDYF | FRA: KM00) (“Algo Grande” or the “Company”) announces the

commencement of advanced surface and geophysical programs at its 100%-owned

Adelita Project in Sonora, Mexico, designed to refine and prioritize drill targets ahead of

its Phase II drill program scheduled to commence 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

LEGAL_49111854.1

 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.

granodiorite sample (see Figure 3).

The mineralized granodiorite boulder was encountered at approximately one metre depth

during access construction for drilling activities.

clearing access for phase I drilling. Rock sample found at 1 meter of depth.

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.
