Moved material
Blocks of altered host rock, lamprophyre and mineralized material may be carried away from their original bedrock position.
THOR IN 3D · SURFICIAL COVER
Rockslides.Where transported rock
becomes an exploration vector.
Large slope failures have moved and concealed pieces of the Thor geological system. Mineralized float, mapped slide direction and subsurface geophysics help project intact targets beneath or behind that cover.

01 · DISTRICT EXPRESSION
The surface can hide the continuation of the system.
Rockslides at Thor are large gravity-driven deposits, not minor talus aprons. They can transport mineralized blocks downslope while covering the bedrock structures from which those blocks were derived.
Fused terrain interpretation
LiDAR relief and conductivity viewed together.
Terrain morphology helps distinguish displaced slide material, while conductivity and mapped structures support projections toward possible intact bedrock sources.
Covered source
The same slide mass can conceal the structure or vein system that supplied mineralized float.
Integrated vector
Float observations are combined with slide direction, structural projection and geophysics rather than interpreted alone.
02 · LANDFORM ANATOMY
A slope failure leaves readable geometry.
A main scarp and crown define the source area. The displaced body moves downslope toward a bulging toe, commonly accompanied by cracks, ridges and disturbed vegetation.
Gravity
Movement begins when downslope stress exceeds the material's available shear strength.
Water
Rainfall and snowmelt can add weight, raise pore pressure and reduce friction.
Fractured slopes
Weak, broken or oversteepened terrain is more susceptible to large mass movement.
Scarps and toes
Cracks, displaced blocks, ridges and a bulging toe help map the slide envelope.
Conceptual anatomy
From crown to toe.
The source-facing scarp, displaced body and downslope toe provide a framework for tracing likely transport direction back toward intact bedrock.
03 · PRIORITY AREAS
Two covered corridors frame the exploration problem.
The Ferguson and Horton–Mountain Goat Creek areas illustrate the same method at different positions: follow displaced mineralized material up-slope, then test the structure beneath or behind slide cover.
Southeastern continuation
Ferguson Rockslide.
The source interpretation projects a possible continuation of the Thor mineralized corridor for nearly two kilometres beneath slide cover southeast of the known deposit.
Northwestern vector
Horton–Mountain Goat Creek.
Mineralized boulders and float northwest of Thor are evaluated with VLF, EM-37 and airborne conductivity trends to search for a nearby concealed source.
04 · EXPLORATION LOGIC
Treat the float as evidence, not the endpoint.
The working model distinguishes where a mineralized block rests today from the bedrock source that produced it. Each interpretation remains a target hypothesis until it is tested by mapping, geophysics and drilling.
Observe
Record mineralized float, altered lithologies and the boundaries of the slide deposit.
Reconstruct
Use scarps, flow direction and LiDAR morphology to estimate the path of displacement.
Project
Carry mapped structures and conductive trends beneath or behind the surficial cover.
Test
Rank concealed bedrock targets, then evaluate them with focused fieldwork and drilling.
