Flow Metals Models 3D Subsurface of Porphyry-Epithermal Target at Sixtymile Valley

Flow Metals advances Sixtymile with 3D geophysical modelling, but value remains long-term.

What the company is saying

Flow Metals Corp. reports the completion of a 3D geophysical data compilation and re-processing program at its Sixtymile Gold Project in Yukon, emphasizing this as a technical milestone to refine exploration targeting for both gold and critical minerals. The company highlights that 27.9 line-kilometers of historical CSAMT data were reprocessed into a unified 3D resistivity block model, enabling better visualization of subsurface structures. The announcement frames the new model as a tool to connect historical drill intercepts, surface mapping, and geophysical domains, with the aim of focusing future drilling on testable porphyry and epithermal targets. Scott Sheldon, President and CEO, positions the Sixtymile Valley option as an opportunity to expand into critical minerals, leveraging both recent surface discoveries and historic drill results. The technical content was reviewed and approved by Harley Slade, P.Geo., a director and Qualified Person under NI 43-101. The company acknowledges that much of the historical data has not been independently verified and cautions that these results may not be reliable or indicative of mineralization.

What the data suggests

The company has completed a technical milestone by reprocessing 27.9 line-kilometers of historical CSAMT data from 27 survey lines into a 3D resistivity model, integrating this with 2010 airborne magnetic grids and 2026 surface mapping. The model resolves key structural features such as the Sixtymile Fault zone and correlates resistivity domains with intervals of hydrothermal alteration and anomalous copper-molybdenum and silver-gold in historical drill core. No new drill results, resource estimates, or economic studies are disclosed. The technical team is now digitizing fault architecture and statistically analyzing historical drill logs to establish vectors for future drill targeting. The announcement provides detailed technical context but lacks quantitative exploration results or financial data. The evidence supports that the company is still in the data-integration and target-refinement phase, with actionable exploration outcomes yet to be realized.

Analysis

The announcement is upbeat, highlighting the completion of a 3D geophysical data compilation and re-processing program at the Sixtymile Gold Project. The realised progress is the technical milestone of compiling and modelling historical geophysical data (27.9 line-kilometers of CSAMT), which is a legitimate step in early-stage exploration. However, the majority of key claims are forward-looking, focusing on how the new model will guide future exploration, enable targeting of critical minerals, and support the next phase of drilling. There are no new drill results, resource estimates, or economic studies disclosed, and the technical team is still in the process of digitizing and integrating data for future targeting. The district consolidation and optioning of new ground signal capital intensity, but there is no immediate earnings or resource impact. The language around 'broadening into critical minerals' and 'prioritizing the next phase' inflates the narrative relative to the actual, incremental technical progress. The data supports that a technical milestone has been achieved, but the investment case remains long-dated and unproven.

Risk flags

• ●Reliance on historical data poses a risk, as the Qualified Person has not independently verified the CSAMT, airborne magnetic, or drilling results, and the company cautions that these may not be reliable or indicative of mineralization. This uncertainty could undermine the targeting effectiveness of the new 3D model.
• ●The absence of new drilling, resource estimates, or economic studies means that the project remains at an early, pre-resource stage, with no immediate pathway to demonstrating economic viability or mineral inventory.
• ●The announcement signals capital intensity through district consolidation and optioning of the Sixtymile Valley target area, yet there is no disclosure of funding, budget, or how future exploration will be financed, raising questions about the company's ability to execute the next phase.
• ●Forward-looking statements about critical mineral potential and future drill targeting are not yet supported by concrete results, increasing the risk that future exploration may not yield economically significant discoveries.
• ●Operational risks include the need for timely permitting, First Nations consultation, and access in Yukon, as well as exposure to commodity price fluctuations and seasonal constraints, any of which could delay or impede progress.

Bottom line

Flow Metals has completed a technically detailed 3D geophysical modelling program at its Sixtymile Gold Project, integrating historical and recent data to refine exploration targets for gold and critical minerals. The announcement demonstrates progress in data compilation and target definition, but no new drill results, resource estimates, or economic studies are provided. The company remains reliant on unverified historical data, and the next steps—digitizing fault architecture, integrating datasets, and statistically analyzing drill logs—are still months from delivering actionable exploration outcomes. Investors should recognize that the path to value realization is long-term and contingent on successful future drilling and resource definition. The most important takeaway is that while technical groundwork is advancing, the investment case hinges on future exploration success, not on any immediate operational or financial milestone.

Announcement summary

(CSE:FWM) Flow Metals Corp. has completed a 3D geophysical data compilation and data re-processing program at its flagship Sixtymile Gold Project in western Yukon. The program was conducted by in3D Geoscience Inc. under the direction of Todd Ballantyne, P.Geo. The 3D data compilation enables evaluation of subsurface structures at the Sixtymile Valley copper-molybdenum porphyry and epithermal gold-silver targets. A total of 27.9 line-kilometers of historical controlled-source audio-frequency magnetotelluric (CSAMT) data were reprocessed from original 2D inversions into a unified 3D resistivity block model. The 3D model connects 2D cross sections into a continuous volume, allowing tracing of fault geometry and correlation of resistivity domains with historic drill intercepts. The model resolves the Sixtymile Fault zone, cross-cutting structures, and distinct resistivity domains that coincide with hydrothermal alteration, brecciation, and anomalous copper-molybdenum and silver-gold intervals in historical drill core. The company is using a mineral systems approach to focus exploration on areas with key subsurface features, deprioritizing those that lack them. Scott Sheldon, President and CEO of Flow Metals, stated that the Sixtymile Valley option provides an opportunity to broaden into critical minerals, and that the new 3D model, combined with recent surface discoveries and historic copper-molybdenum drill results, will help prioritize the next phase of exploration. The Sixtymile Valley target area was optioned as part of the company's 2026 district consolidation, adding a critical minerals component to the project's primary gold focus. Historical drilling in the area intersected porphyry-style alteration and brecciation with anomalous copper, molybdenum, silver, and gold. Surface mapping completed by the company in 2026 found pervasive clay alteration and vuggy residual quartz at Miller Creek, indicating preservation of the uppermost levels of a high-sulphidation epithermal system. The company initiated the 3D CSAMT modelling program to map these subsurface features and test their connectivity at depth. The 3D model shows a branching network of steeply dipping conductive structures alongside large high- and low-resistivity domains, which broadly correlate with intervals of hydrothermal alteration, brecciation, and anomalous polymetallic mineralization in 2011 drill holes. The technical team is now digitizing the primary fault architecture in 3D space and cross-referencing resistivity volumes against newly filtered 2010 airborne magnetic grids. The company will also overlay its 2026 surface mapping on the block model to trace newly identified epithermal and lithocap zones to depth, and conduct statistical analysis of historical drill logs and assay intervals against geophysical clusters to establish quantitative vectors for future drill targeting. The technical content of the news release was reviewed and approved by Harley Slade, P.Geo., a director of the company and Qualified Person as defined by National Instrument 43-101. The historical CSAMT, airborne magnetic, and drilling data referenced were produced by a previous operator and have not been independently verified by the Qualified Person. The company considers the historical data relevant as a guide to exploration but cautions that the historical results may not be reliable or indicative of mineralization on the property.
