How it works

From raw CSV to a signed technical report — in five steps.

No installer. No IT ticket. No admin rights. Every step is reproducible, auditable and driven by your own project data.

Try the flow yourself Watch a 3-minute walkthrough

Step 01
Sign up
30 seconds
Create a workspace with your work email. No credit card required. Starter plan is free forever for one project and up to 100 000 drillhole intervals.
You'll have
- Workspace URL
- First user account
- Empty starter project
Step 02
Import data
5 – 30 minutes
Drop your Collar / Survey / Assay / Lithology CSVs. Automatic column mapping, coordinate reprojection, and standards / blanks / duplicates QAQC dashboards catch data quality issues before they contaminate downstream stages.
You'll have
- Validated drillhole DB
- QAQC PDF pack
- Interactive 3D drillhole viewer
Step 03
Model & estimate
1 – 3 days
Composite intervals, code lithology domains, model implicit RBF ore shells, fit variograms, and run IDW or Ordinary Kriging. Slope-of-regression classification produces Measured / Indicated / Inferred categories with confidence tercile analysis.
You'll have
- Ore wireframes
- Classified block model
- Grade-Tonnage curves
Step 04
Optimise & schedule
Half a day
Run Lerchs–Grossmann pit optimisation with slope zones by rock domain and revenue-factor sensitivity sweeps. Generate nested pushbacks and multi-period NPV-optimised production schedules with tornado sensitivity analysis.
You'll have
- Optimal pit shell
- Pushback design
- NPV-optimised schedule
Step 05
Publish report
10 minutes
One-click code-compliant report — CRIRSCO · SAMREC · PERC · SME · S-K 1300 · NAEN · KAZRC — in DOCX, PDF, XLSX or PPTX. Every plot, table and paragraph is stamped with the exact model version and dataset SHA-256 hash for full audit-grade traceability.
You'll have
- Signed PDF report
- Editable DOCX
- Data appendix (XLSX)

Under the hood

What's actually running when you click "Estimate".

Four engineered components that make the whole workflow fast, auditable and reproducible.

Ordinary Kriging engine

Experimental + modelled variograms with nugget / sills / ranges. Search neighbourhoods, quadrant / octant restrictions. Cross-validation and QKNA panels built in.

GPU-accelerated 3D viewer

InstancedMesh rendering of 250 000 blocks at 60 FPS. Section clipping, frustum culling, custom shaders. Runs on any WebGL 2 GPU including Apple Silicon.

Lerchs–Grossmann solver

Bench-level max-flow LG solver scales to 500 000 blocks. Sensitivity sweeps across 12 revenue factors complete in under 20 minutes on a mid-range laptop.

Signed report pipeline

Deterministic DOCX / PDF / XLSX / PPTX generation. Cryptographically-signed SHA-256 hashes make every report bit-for-bit reproducible years later.

Legacy vs SMIN

Same job. Very different day.

Aspect	Legacy desktop stack	SMIN
Time to first block model	2 – 4 weeks	< 1 day
Setup / installation	IT ticket + admin rights per user	Open a URL
CSV round-trips	Constant	Zero
Version mismatch pain	Weekly	None (single source of truth)
Multi-user collaboration	Emailed copies	Real-time workspace
Audit trail	Manual	Immutable, per-action
Report generation	Word merges + copy-paste	One click
On-prem / air-gapped	Per-seat licences	Included on Enterprise

Common questions

The three questions we get most.

How do I import from Datamine / Vulcan / Micromine?

Export your block model, wireframes and drillhole database to CSV / GSLIB / DXF from your legacy tool. SMIN's data manager will map columns, reproject coordinates and validate integrity — no scripting required.

Can I run SMIN offline?

The 3D viewer and reporting UI work offline once a project has been synced. Compute-heavy workflows (kriging, LG optimisation) require a connection. Enterprise on-prem deployments run fully air-gapped.

How does SMIN handle very large block models?

Regularised block models up to 10 million cells are handled server-side. The 3D viewer streams 250,000+ blocks at 60 FPS with LOD switching for the rest. Enterprise deployments scale to 100M+ cells.
