He has been critical throughout the acquisition process and is making an important contribution to building Algo Grande Copper as we advance Adelita.”
Commenting on his appointment, Mr. Rocha stated:
“I am honored to join Algo Grande Copper Corp. as Vice President of Exploration at a time that is critical for global critical minerals. The Adelita project represents a high-quality copper-gold-silver skarn-porphyry system that is aligned with long-term fundamentals. The integration of modern 3D geophysical reprocessing, AI-based target generation and a high-resolution ground magnetic survey at Cerro Grande provides a solid technical framework to accelerate discovery and reduce project risk. Combined with geochemistry, prospecting and oriented core drilling, this data will significantly improve our ability to predict additional high-grade skarn zones along strike and at depth. I look forward to advancing Adelita through disciplined, data-driven exploration.”
Geophysical Reprocessing and Interpretation
The reprocessing program included modern 3D magnetic vector inversion (MVI and QMVI), 3D DCIP inversion and magnetotelluric (MT) modeling, integrated with normalized geochemical data sets and updated structural interpretations. The results define a coherent mineral system characterized by:
- Resistive intrusion bodies interpreted as porphyry centers
- Magnetite-rich skarn horizons associated with high-grade copper-gold-silver mineralization
- Deep, vertically extensive conductive corridors interpreted as feeder structures connecting the porphyry source with the overlying skarn mineralization
These feeder zones are consistently observed across multiple MT profiles and are believed to play a key role in the formation of mineralization throughout the Adelita system.
Geophysical IP and VTEM Reprocessing and Interpretation by Southern Geoscience
The reprocessing of historical data by Southern Geoscience aimed to reprocess and reinterpret the historical IP, VTEM and magnetic data sets at the license area level, adapt the data to modern technology standards, validate historical interpretations and generate new targets and concepts.
This work included:
- IP Data Processing and 3D Modeling
- Use of SGC’s proprietary IP processing software
- QAQC of all data
- Preparation and modeling of data with RES3DINV
- Improvement of VTEM and magnetic data processing
- Gridding of magnetic data
- Grid filtering from TMI to RTP
- Image processing and enhancement of EM
- Image processing enhancement of TMI
Highlights of this work include:
- The largest and most resistant body is located below existing drilling below the Cerro Grande Skarn discovery zone (Figure 2).
- The main resistive bodies exhibit anomalous magnetic signatures in their vicinity.
- The chargeability results show a 4x anomaly of the background value in the northern part of the survey.
- The chargeability anomalies on the property have not yet been verified by drilling.

Geophysical Reprocessing and Interpretation, Lineament Analysis and Machine Learning-Assisted Target Generation by GSM Geoscience
Algo Grande has conducted a comprehensive, fully integrated geophysical and geochemical interpretation of the project to refine the geological model and generate highly reliable exploration targets within the property.
This work included:
- Interpretation of airborne magnetic data, including Reduced-to-Pole products and 3D Magnetic Vector Inversion (MVI)
- Review and interpretation of ground geophysical data, including 2D and 3D DCIP inversions and magnetotelluric (MT) sections
- Multivariate geochemical analysis using robust statistical normalization, metallogenic indices and dedicated clustering
- Machine learning-based prospectivity modeling using airborne magnetic derivatives and structural proximity metrics
- 2D and 3D integration of all data sets to define exploration targets and prioritize follow-up drilling
This work was conducted by GSM Geoscience and focused on characterizing the geometry, controls and extent of the skarn-porphyry system on the property.
Key results of this work include:
1. Definition of a coherent porphyry-skarn mineral system
The integrated interpretation confirms that Adelita hosts a porphyry-skarn mineral system (Figure 3) that developed in a compressive to transgressive tectonic regime. The system architecture is consistent with globally recognized porphyry-skarn models and includes:
- A deep structural feeder zone
- a resistive intrusion body interpreted as a potential porphyry stock
- A laterally extensive skarn horizon developed at the contact between intrusion and carbonate rock.
- Structurally controlled fluid pathways determine mineral distribution
- The upper contact of the resistive body, interpreted as a porphyry body, corresponds to the skarn horizon in Cerro Grande, which has been intersected by drilling in the past
This mineral system is independently supported by geophysical, geochemical and drilling investigations.

2. Identification of a deep, structurally controlled feeder zone (MT)
Magnetotelluric sections consistently show a deeply rooted (Figure 2), vertically extensive conductive corridor near the Cerro Grande area that extends into the southern part of the project.
Figure 4 – The feeder zone can be traced up to 1.5 km south of Cerro Grande. This structure has largely not yet been investigated.
This conductive feature is interpreted as:
- A significant structural zone or shear corridor
- The primary pathway for magmatic and hydrothermal fluids
- The feeder structure connecting deeper magmatic sources with the upper skarn and porphyry environment
The geometry, continuity from depth and repetition of this feature across multiple MT lines provide a high degree of confidence in its presence and geological significance (Figure 4).
This vertical feature is scheduled to be targeted by the completion of drilling in February 2026.
3. Mapping of mineralized skarn horizons
The skarn horizons known in the Cerro Grande discovery zone are consistently identified by MT and DCIP measurements as well as historical drilling at the contact point between the intrusive body and the carbonate-bearing parent rocks (Figure 5 and Figure 6).
Drilling that intersected this zone encountered:
- Garnet skarns, hornfels and exo-skarns assemblages
- Cu-Au-Ag mineralization
- Alteration arrays consistent with the proximal skarn environment.
DCIP inversions highlight polarizable responses associated with this horizon, while resistivity models suggest that the skarn occurs in a relatively resistive area compared to the surrounding rocks.

4. Integrated Exploration Targets
Based on the integration of all data sets, 18 geologically and geophysically constrained targets (AD01-AD18) and 14 additional targets from machine learning were defined and ranked according to the strength and coherence of their signatures (Figure 7):
- Priority 1: Strong convergence of MT conductivity, IP chargeability, magnetic responses, structural features and geochemical anomalies
- Priority 2 and 3: Represent increasingly more distant or structurally complex positions within the system
- Machine learning targets that extend prospectivity to areas without ground magnetic geophysics. These targets reflect strong geophysical similarities to known mineralized areas
Figure 7 – High-priority exploration targets. Areas for machine learning are highlighted in light blue
These targets offer immediate opportunities for model validation. They are scheduled to be tested on site in the first months of 2026 and verified by drilling if their suitability is confirmed.
This work was conducted in collaboration with GSM Geoscience.
High-Resolution Ground Magnetic Survey
Algo Grande has commenced a high-resolution ground magnetic survey over the high-grade Cerro Grande skarn zone as part of the Adelita project. The survey is being conducted by the University of Sonora through its Department of Geology, leveraging their regional expertise and academic specialization in applied geophysics.
The survey utilizes high-precision Overhauser magnetometer technology (GEM GSM-19) to acquire total magnetic field data over the entire target area. The data is collected along closely spaced, east-west oriented survey lines at approximately 20-meter intervals, providing significantly higher resolution than historical airborne magnetic data.
The program is focused on the following objectives:
- Delineate the geometry and continuity of magnetite-rich skarn bodies
- Improve the definition of faults and structural corridors that control mineralization
- Identify subtle magnetic responses associated with hidden intrusions and feeder zones
The survey data will be processed and interpreted using specialized geophysical software. The results will be fully integrated into the company’s existing geological and geophysical 3D model, along with the reprocessed IP, MT and magnetic data sets, to support ongoing and future drilling programs.
Impact on Exploration and Next Steps
The results of the geophysical re-evaluation, AI-based prospectivity analysis and the commencement of high-resolution ground magnetic surveys significantly improve the company’s understanding of the extent, architecture and controls of mineralization at the Adelita project. Algo Grande is currently in the process of integrating multiple high-quality data sets to create a solid geological thesis for the system.
This integrated approach combines:
- Reprocessed 3D magnetic, IP and MT data sets
- Results from the current drilling program, which for the first time included oriented core drilling at Adelita
- Ongoing surface mapping, sampling and upcoming trenching program
- Geochemical data from soil and rock sampling programs
Together, these data sets will be integrated into an evolving geological and structural 3D model to improve understanding of skarn geometry, continuity and controls on mineralization. The goal is to systematically reduce geological uncertainties and generate well-defined, low-risk drill targets.
