Introduction: A New Chapter in Chilean Mineral Exploration

Chile’s vast mineral resource endowment underpins its global leadership in copper and gold production. The mogotes geophysical survey in South America’s prolific Vicuña mineral belt has unveiled a major copper-gold anomaly, setting new benchmarks for porphyry exploration and epithermal deposit discovery. At Farmonaut, we’re dedicated to spotlighting such industry-defining advances, and this latest development could reshape exploration strategies across Chile, Argentina, and beyond.

With state-of-the-art geophysical surveys and 3D geophysical modeling, coupled with robust satellite technology and precision data tools, the mining industry is now positioned for a new era of targeted drill target identification. In this post, we unravel the science, data, and strategic business implications surrounding mogotes’ discovery near the celebrated Filo del Sol copper-gold-silver resource.

Geological Context: The Vicuña District and the Filo Sur Trend

We begin by situating the mogotes mineral exploration project in its broader geological landscape. The Vicuña District, spanning Chile and Argentina, is renowned for several globally significant discoveries, like Filo Del Sol, Lunahuasi, and Los Helados. These resources sit along a dynamic north-south (N-S) copper-gold-silver mineral belt, frequently associated with intrusive porphyry systems and high-sulfidation (HS) epithermal deposits.

The adjacent Filo Del Sol resource—operated by Lundin Mining and BHP—remains open and undrilled towards the Mogotes claims. The confluence of favorable geology, robust structural controls, and prolific mineralization signatures makes this area a high-priority target for resource expansion and economic uplift in Chile’s mining sector.

• Home to mega-deposits: Filo del Sol, Lunahuasi, Los Helados
• Main ore types: Porphyry copper-gold-silver and HS epithermal systems
• Trends: Open mineralized systems, underexplored extensions, robust regional alteration

This sets the stage for the recent mogotes geophysical survey—an initiative promising to unlock new discoveries and raise South America’s profile in global copper gold mineralization trends.

Mogotes Geophysical Survey: Overview & Purpose

The 2025 mogotes geophysical survey deployed advanced Deep IP/MT (Induced Polarization / Magnetotellurics) and Vector IP/MT (VIP/MT) systems to meticulously analyze subsurface physical properties. Conducted across a four-line, 10.7 km grid covering multiple targets (Los Mogotes, Meseta, Cumbre, and Cuenca), its goals included:

• Delineate subsurface geophysical anomalies associated with mineralization
• Correlate geophysical signatures with known surface rock chip and alteration anomalies
• Enable drill target identification for concealed porphyry and epithermal systems
• Integrate new data with existing 2023 Filo Sur 3D geophysical datasets for comprehensive anomaly modeling

The survey’s cutting-edge parameters—leveraging proprietary 3D VIP/MT hardware and multi-line processing—targeted relatively shallow depths (180–400m) for efficient detection. Early results exceeded expectations, highlighting a robust, near-surface geophysical anomaly coincident with surface mineralization. This provides a compelling exploration narrative for stakeholders and positions Mogotes Metals Inc. alongside the region’s most successful explorers.

Discovery of the Major Copper-Gold Anomaly

The crux of the mogotes geophysical survey success lies in the outline of a large-scale, near-surface geophysical anomaly directly south (2.8 km) of the famed filo del sol deposit. Here’s what our analysis of the anomaly reveals:

• Location & Dimensions: The main anomaly is situated directly on trend, south of the Filo Del Sol resource—an area underexplored and open for expansion.
• Geophysical Characteristics: The initial L2 line data highlights an MT anomaly (<100 ohm.m) with a substantial width of approximately 800m, enveloped by a chargeability (IP) halo of 1.7km.
• Depths: The anomaly apex is found between 180m to 400m beneath the surface, a relatively shallow interval for such high-value targets.
• Anomaly Footprint: Early processing validates the presence of a large-scale, conductive, and chargeable zone—the classic geophysical signature of a concealed porphyry copper-gold system.
• Coincident Surface Geochemistry: The geophysical anomaly is located directly beneath previously sampled rock chip and alteration anomalies. This spatial overlap significantly increases the probability of copper gold mineralization at mineable depths.

With the presence of a chargeability halo (indicative of a pyrite envelope) and strong conductivity, geoscientists believe the anomaly may represent an undrilled porphyry/HS centre on the active Filo trend—a narrative reinforced by existing scientific literature on Chilean mineral belts.

3D Geophysical Modeling & Anomaly Interpretation

Leveraging the Southern Rock Geophysics proprietary 3D VIP/MT system for the filo sur project, Mogotes has blended 2023 and 2025 survey data to construct integrated 3D geophysical models for the region. This methodology empowers technical teams to:

• Visualize anomaly geometry, continuity, and zonation at depth
• Assess the proximity and relationship of surface geochemical anomalies (rock chip, soil grid, trench samples) to subsurface geophysical features
• Better rank and prioritize drill targets based on anomaly strength, volume, and alteration assemblages

The 3D modeling approach streamlines drill testing and increases the odds of intersecting high-grade zones while minimizing operational risks and unnecessary costs—aligned with modern, data-centric mineral resource assessment practices.

Drill Target Identification & Mineralization Potential

The mogotes geophysical survey has directly contributed to the identification of compelling new drill targets. Here’s a breakdown of how the process unfolds:

1. Surface-Supported Targeting: Initial surface sampling yields geochemical anomalies in rock chip and soil data, highlighting potential mineralization zones.
2. Geophysical Validation: Coincident with surface anomalies, robust MT and IP features at shallow to moderate depths serve as subsurface vectors to ore.
3. 3D Integration: Datasets are merged into a spatial model, prioritizing anomalies with the best geometry, depth, and alteration halo characteristics.
4. Drill Planning: With vectorized anomaly mapping, technical teams design angled holes to maximize the probability of intercepting concealed porphyry copper-gold systems.

At least three high-priority drill targets have emerged in Mogotes, each characterized by strong conductive and chargeable features within a wide alteration envelope. Early data shows classic “telescoped” alteration patterns as documented in regional economic geology studies.

Rock Chip Sampling, Alteration Patterns, and Assay Results

Successful rock chip sampling is a linchpin of the mogotes exploration program. The latest infill and surface (Los Mogotes rock chip) campaigns reveal:

• Multi-gram gold and high copper grades in near-surface rock samples within alteration zones
• Widespread occurrence of advanced argillic and silicic alteration assemblages, consistent with porphyry and epithermal system models (see references: Perello et al., Hedenquist & Arribas)
• Ongoing soil, trench, and channel sampling programs to extend anomaly footprints

All samples are processed under a rigorous QA/QC framework, with geochemical analysis performed at ALS laboratories in Chile, Argentina, and Peru, using industry-standard fire assay and multi-element analysis protocols. The spatial overlap of geochemical results (surface) and resistivity/chargeability anomalies (subsurface) forms a powerful case for further drilling and exploration investment.

Assay results, combined with blockchain-based traceability solutions, offer secure and transparent data management—facilitating compliance and increasing confidence for investors and regulators in both the mining and agricultural supply chains.
