Red Metal Resources Ltd. (CSE: RMES) has released initial findings from a three-dimensional induced polarization (IP) survey conducted at its Carrizal Copper-Gold-Cobalt Property in Chile’s Atacama Region. The survey identified a continuous chargeability trend across six consecutive lines spaced 200 metres apart, covering roughly one kilometre in the southern block. These anomalies are interpreted as promising indicators of disseminated to semi-massive sulphide mineralization. Notably, the company highlighted that prior drilling has yet to test the highest IP anomalies delineated by this survey.
Key Highlights
- Red Metal Resources Ltd. (CSE: RMES) announced preliminary results from a 3D IP survey at its Carrizal Property near Vallenar, Chile.
- Chargeability anomalies were detected across all six survey lines (L0, L200, L400, L600, L800, and L1000), each approximately 2,000 metres in length and spaced 200 metres apart.
- The chargeability trend extends across the southern block for about one kilometre and remains open both along strike and at depth.
- A secondary chargeability trend was identified at depth in the eastern sections of Lines L800 and L1000, aligning with a mapped and sampled vein.
- The company plans to incorporate northern block survey data into a 3D model and schedule drilling to test top-priority targets.
3D IP Survey Methodology and Technical Details
Red Metal reported that the IP survey was executed by independent contractor Geophysical Studies Chile using a true three-dimensional approach with overlapping data blocks. The survey employed a pole-dipole IP resistivity method in the time domain via a 3D distributed array with offset configuration GS'DAS-DCIP3D, utilizing a MultiRx system by GDD. This comprehensive acquisition strategy was designed to capture subsurface chargeability and resistivity variations across the exploration area.
The survey grid comprised six lines, each 2.0 kilometres long and spaced 200 metres apart across the southern block. Receiver spacing was 125 metres inline, with the infinite current electrode positioned about 3.0 kilometres away. Current was injected using a GDD-Tx4 transmitter rated at 5000 watts, 2400 volts, and 20 amperes, with transmitter poles between receiver pairs. During injection along a primary line, adjacent lines recorded signals simultaneously on 32 channels using two dual 16-channel GDD receivers. This overlapping setup enabled true 3D data acquisition with an online level up to 20.
Primary Chargeability Anomaly and Sulphide Mineralization Indicators
The survey revealed a primary chargeability high coinciding with historic drilling and a zone of reduced resistivity. The company interprets this as a favourable indicator of disseminated to semi-massive sulphide mineralization, consistent with surface structural geology mapping and sampling.
The southern block’s chargeability trend is continuous across all six lines and remains open at depth on northern lines, indicating potential unexplored mineralization below current survey depths. The survey targeted the primary sulphide zone between 100 and 500 metres depth, relevant for underground and open-pit exploration.
Secondary Chargeability Anomaly and Eastern Block Insights
In addition to the primary trend, a secondary chargeability anomaly was detected at depth in the eastern portion of Lines L800 and L1000, aligning with a mapped and sampled vein. This suggests multiple mineralization styles or structural settings within the southern block that may require separate drilling assessments.
The presence of these features at depth in eastern lines indicates the property may host mineralization in varied geometric configurations, influencing future drilling priorities and resource estimation.
Historical Drilling and Untested High-Priority Anomalies
Red Metal emphasized that existing drilling has not tested the highest IP anomalies identified by this survey. Previous drilling sampled one of three interpreted structures but did not reach zones with the strongest chargeability responses. This gap presents a significant exploration opportunity to target untested or extended mineralized zones at depth or along strike.
Integration of Mapping, Sampling, and Geophysical Data
The chargeability responses correspond with two surface-sampled structures and one that has been drill tested, as referenced in the company’s April 28, 2026 news release. This correlation supports the interpretation that the anomalies represent valid mineralization targets rather than survey artefacts.
Red Metal plans to integrate all IP results, including pending northern block data, with historical drilling, mapping, and geochemistry into a comprehensive 3D model to refine and prioritize drill targets before advancing exploration.
Management Remarks and Technical Validation
President and CEO Caitlin Jeffs, P.Geo., described the preliminary IP results as "very encouraging," highlighting the identification of strong chargeability anomalies coincident with mapped and sampled structures. She labeled these as "compelling, drill-ready targets," reflecting confidence in the survey’s quality and exploration relevance.
Jeffs, a Qualified Person under NI 43-101, reviewed and validated the geophysical data and inversion results provided by Geophysical Studies Chile, ensuring technical reliability.
Pending Northern Block Data and Future Plans
Results from the northern block remain outstanding. Once received, the company will integrate all data into a 3D model alongside historical information to finalize the mineralization framework. This comprehensive approach aims to optimize drill target prioritization based on geophysical, geological, and historical data alignment.
Following integration, Red Metal intends to prioritize drilling targets carefully, though no specific timelines, budgets, or drill hole counts have been disclosed.
Exploration Cautionary Statement
The company cautioned that the IP results are preliminary and based on geophysical inversion modeling. Geophysical anomalies do not inherently confirm mineralization and require drilling for validation. This standard industry disclaimer underscores the difference between geophysical signatures and economically viable mineral deposits.
