Mining Engineering · Resource Advisory

Your deposit has answers. We ask the right questions.

From first core log to final extraction plan — Seam interprets the geology, models the economics, and engineers the compliance. Three continents. Eighteen years of field-proven methodology.

"How do I know if my deposit is economically viable?"

Economic viability isn't a single number — it's the intersection of five compounding variables. Before any study is commissioned, Seam runs a rapid desktop scoping to identify which variables are the swing factors for your specific deposit and jurisdiction.

Grade × TonnageMust clear cut-off grade at projected recovery rates
Strip RatioWaste:ore ratio drives haulage costs in open pit scenarios
Metallurgical RecoveryBench-scale test work required before any study

Feasibility Stage · Q&A

"What's the difference between a PEA and a DFS?"

Both are feasibility studies — but they answer different questions for different audiences. A PEA tells your board whether the project could work. A DFS tells your bank that it will work, backed by drilling density, metallurgical test work, and engineered cost estimates.

The most common mistake junior companies make: commissioning a DFS before the geology is understood well enough to defend it. Seam prevents that by staging the work — each phase only proceeds when the preceding uncertainty has been resolved.

The investor-readiness threshold
PEASufficient for early-stage equity raises and initial resource announcements
DFSRequired for project financing, streaming agreements, and construction permits
Operating Stage · Geotechnical

"What actually causes slope stability failures — and how do we prevent the next one?"

Slope failures are rarely sudden — they're the accumulated result of deferred monitoring, under-designed drainage, and geotechnical assumptions that weren't revisited as the pit deepened. Seam's forensic slope review identifies the primary mechanism within 48 hours of mobilisation.

For new operations, our geotechnical program integrates directly with the mine plan — slope angles are not constants, they're engineered variables that change with depth, lithology, and groundwater regime.

Slope Failure Causal Analysis · Risk Matrix

Primary failure mechanisms by frequency

Groundwater PressureHigh Risk

Pore pressure buildup in pit walls is the leading cause of unplanned slope movement in tropical climates

Weak Rock Mass (UCS <20 MPa)High Risk

Saprolite and highly weathered zones require flatter inter-ramp angles and monitoring prisms

Discontinuity OrientationHigh Risk

Adversely dipping joint sets parallel to pit walls create wedge or planar failure modes

Seismic LoadingMedium Risk

Dynamic loading reduces effective friction angle — critical in Andean and Pacific Rim operations

Waste Dump SaturationMedium Risk

Undrained loading of valley-fill dumps is a common compliance failure post-heavy rainfall events

Seam has investigated 34 unplanned slope events across Africa, South America, and Australia since 2012. Zero lost-time injuries on any Seam-managed remediation.
