Carbonaceous material
Graphite-rich schist provides a direct explanation for part of the strong conductive response observed in core.

Tusks.Two deep conductors
beneath Thor.
North Tusk and South Tusk are steep, low-resistivity bodies that wrap around and extend beneath the Thor epithermal deposit. Their scale and geometry make them central to the district-scale exploration model.

01 · SYSTEM VIEW
A conductive frame around the known deposit.
Magnetotelluric measurements were inverted into a three-dimensional resistivity model. In that model, the Tusks appear as large, elongated low-resistivity volumes beside and below the Thor deposit, with a geometry that crosscuts the folded host-rock package.
Integrated geological model
North and South Tusks.
The magenta volumes represent a 70 ohm-metre resistivity shell. They sit within a larger interpreted system that includes the epithermal deposit, Silver Cup Anticline, lamprophyre dyke and alteration shell, Borr Zone and I-1 intrusive.
Looking north-northwest
Paired, elongated conductors.
The interpreted South and North Tusks flank the epithermal mineralization and continue to depth.
02 · PHYSICAL FORM
Large in plan.
Steep at depth.
The Tusks are interpreted from geophysics rather than surface exposure. Their mapped physical character establishes a focused set of geological questions.
- 01
Elliptical plan
Two parallel, elongated bodies define the North Tusk and South Tusk.
- 02
Steep plunge
The conductive volumes dip steeply to vertically beneath the deposit.
- 03
Buried expression
No surface exposure is known; the model places the nearest approach at roughly 500 metres below surface near Broadview.
- 04
Strong contrast
Values below approximately 70 ohm-metres distinguish the Tusks from surrounding metasedimentary and volcaniclastic rocks.
03 · DRILL EVIDENCE
A first physical glimpse of the South Tusk.
Deep hole THOR-242 tested the South Tusk during the 2024 program. Taranis reports that the hole entered its upper part at approximately 576 metres, intersecting intensely sheared, carbon-rich material unlike the surrounding host rocks.
- Host material
- Black graphitic schist
- Distinctive texture
- Pyrite fragments or “bombs” to about 4 cm
- Alteration
- Pale to white altered fragments
- Reported carbon
- 4.7% C in black schist
The source page separately captions the photographed core at 549 m. That image depth and the reported approximate 576 m Tusk entry are retained as distinct source observations.

The “Bomb Unit.”
Dark, graphitic and strongly sheared core contains pale altered patches and conspicuous pyrite fragments.
04 · EXPLORATION MEANING
Conductivity is evidence.
Geology supplies the meaning.
Low resistivity can arise from several materials and processes. The value of the Tusk model is therefore in combining geophysics, drill core, structure and spatial relationships—not in treating conductivity alone as proof of mineralization.
Hydrothermal alteration
Clay alteration, sulphides and fluid-driven rock modification may also contribute to zones of low resistivity.
Deep-system context
The Tusks crosscut folded host rocks and sit close to the interpreted I-1 feature, supporting evaluation of a younger, buried intrusive-hydrothermal system.
A system-scale target, not a completed conclusion.
The geometry, scale and first drill evidence make the Tusks important guides to deeper exploration. Further drilling and integrated interpretation are required to determine their origin, continuity and relationship to mineralization.
