Red Pine Exploration Inc. reported that a transient magnetotelluric (MT) survey that was conducted for Red Pine in May 2017 on the Surluga project has been reinterpreted. One-hundred and thirty-seven stations were collected with a station and line spacing of 300 metres. In 2017 a three-dimensional inversion of the phase-tensor, tipper and horizontal magnetic transfer function was performed and recently the results have been further refined and interpreted.

The 3D inversion clearly shows that the Jubilee Stock is a large intrusive complex that is now known to host an intrusion-related gold system. This interpretation is supported by inversions of not only the Mt survey, but airborne time domain electromagnetics (EM) (VTEM), airborne magnetics (Hogg), drilling results, geochemistry, and surface mapping. Historical work from the OGS indicate that the Jubilee Stock is a shallow-level subvolcanic intrusion (Ontario Geological Survey Open File Report 5586), a critical ingredient for the formation of intrusion-related gold mineralization.

Highlights – Geophysics Interpretation: Large intrusive complex mapped; >7km strike X >5km and run over 3km deep; Demagnetization zones identified along structural corridors like the Jubilee sheer; Multiple areas of interest identified with significant discovery potential; Provides direction for current drill program in identifying the Intrusion Related Gold System ‘'IRGS”; Illustrates the extension of the Jubilee and Hornblende shear to depths >1.5km. The correlation of the magnetic 3d inversion (for ease anti correlation shown – blue) adds significant credence to the revised interpretation. The interpreted intrusion is shown in orange and color varies with changes in the resistivity.

The geophysical interpretation: the presence of deep-rooted resistivity anomalies (> 3000 m) that extend to shallow depth (< 200 m), and which in some cases coincide with local shear and fault structures provides evidence of a large intrusive system with well-developed pathways for fluid flow, a critical ingredient for mineral deposition.
