Flow Metals Corp. (CSE: FWM) has completed a 3D geophysical data compilation and reprocessing program at its flagship Sixtymile Gold Project in western Yukon, the company announced on November 9, 2026. The program, carried out by in3D Geoscience Inc., converted 27.9 line-kilometres of historical CSAMT survey data from isolated 2D cross-sections into a unified 3D resistivity block model. The work is designed to map subsurface fault structures and alteration zones at the Sixtymile Valley copper-molybdenum porphyry and epithermal gold-silver targets, potentially sharpening future drill targeting for investors watching the junior explorer.

Key Points

  • Flow Metals Corp. (CSE: FWM) is a Vancouver-based junior mineral exploration company focused on gold and critical minerals in Yukon and British Columbia.
  • The company completed a 3D CSAMT resistivity block model of the Sixtymile Valley porphyry-epithermal target, reprocessing 27.9 line-kilometres of historical survey data.
  • The 3D model reveals a branching network of steeply dipping conductive structures that broadly correlate with historical drill intervals of hydrothermal alteration and anomalous copper, molybdenum, silver, and gold.
  • Investors may be watching whether the new 3D framework leads to prioritised drill targets at the Sixtymile Valley option area.

3D Resistivity Modelling Connects Historical Sixtymile Valley Data

In 2011, a previous operator completed 27.9 line-kilometres of controlled-source audio-frequency magnetotelluric (CSAMT) surveys along 27 lines over the Sixtymile Valley. Those data had been interpreted only as isolated 2D cross-sections. Flow Metals engaged in3D Geoscience Inc., under the direction of Todd Ballantyne, P.Geo., to re-grid those inversions into a continuous 3D block model. The resulting model reveals a branching network of steeply dipping conductive structures alongside distinct high- and low-resistivity domains that the company states broadly correlate with historical drill intercepts of alteration, brecciation, and polymetallic mineralisation.

Surface Mapping Supports Porphyry-Epithermal System Interpretation at Miller Creek

Flow Metals' 2026 surface mapping at Miller Creek identified pervasive clay alteration and vuggy residual quartz, which the company states may indicate that the uppermost levels of a high-sulphidation epithermal system are preserved. Combined with historic porphyry-style drill results showing anomalous copper, molybdenum, silver, and gold, the company's disclosure suggests the valley could host a calc-alkaline porphyry-epithermal system. The 3D CSAMT programme was initiated specifically to test how subsurface alteration zones and fault pathways connect at depth across this interpreted system.

Sixtymile Valley Option Broadens FWM's Critical Minerals Profile

Flow Metals optioned the Sixtymile Valley target area as part of its 2026 district consolidation, announced August 6, 2026, adding a critical minerals component alongside the project's primary gold focus. President and CEO Scott Sheldon stated in the release that combining the new 3D model with recent surface discoveries and historical copper-molybdenum drill results allows the team to look beneath the valley and prioritise the next exploration phase. The technical content of the announcement was reviewed and approved by Qualified Person Harley Slade, P.Geo., a director of the company.

Technical Team Now Digitising Fault Architecture and Integrating Magnetic Data

With the initial 3D block model complete, the technical team is digitising the primary fault architecture in 3D and cross-referencing resistivity volumes against newly filtered 2010 airborne magnetic grids. The company also plans to drape its 2026 surface mapping over the model to trace epithermal and lithocap zones to depth, and to conduct statistical analysis of historical drill logs against geophysical clusters to establish quantitative vectors for future drill targeting. The immediate share price impact was not clear from available public information.
