Getting Started with Orebit Geologist Toolkit — From CSV to First Chart in 5 Minutes

The Orebit Geologist Toolkit is a single HTML file. You open it in any browser. You upload your collar/survey/assay CSVs. You get strip logs, sections, EDA charts, and resource estimates. That’s the whole pitch.

This post walks through getting from “I just bought it” to “I’m looking at my first cross-section” in under five minutes.

What you got when you bought it

A ZIP file. Inside the ZIP:

01-Drillhole-Prep.zip
  └─ Drillhole-Prep.html  (4.8 MB, all assets bundled)
  └─ README.html          (license, quickstart, troubleshooting)
  └─ sample-data/
       └─ collar.csv      (40 Thalanga VMS holes)
       └─ survey.csv      (downhole survey records)
       └─ assay.csv       (1,521 sample intervals, AU/CU/PB/ZN/AS/FE)
       └─ geology.csv     (lithology codes per interval)

Each phase is a separate ZIP. The bundle gives you all three (Drillhole Prep, Drilling EDA, Resource Estimation) plus shared sample data.

System requirements

• Any modern browser (Chrome, Firefox, Safari, Edge)
• 4 GB RAM (8+ recommended for large datasets)
• That’s it. No install, no account, no internet required.

The file runs entirely in your browser. Once it’s loaded, you can disconnect from the network and it’ll keep working. Your data never gets uploaded anywhere — there’s no server.

The 5-minute walkthrough

Minute 1: Open the file

Double-click Drillhole-Prep.html. It opens in your default browser. You’ll see:

• Top header: “Orebit · Drillhole Prep” with a Phase 01 badge
• Left sidebar: 12 numbered workflow steps (01 Tutorial → 12 Export)
• Main area: a welcome modal with a “Take the 6-step tour” button

Click “Take the tour” if it’s your first time. Six guided callouts explain the layout in 60 seconds. Or click “Skip” to jump in.

Minute 2: Load the sample data

Click “02 Import” in the sidebar. You’ll see four upload boxes:

1. Collar CSV
2. Survey CSV
3. Assay CSV
4. Geology CSV (optional)

Drag the four sample files from sample-data/ into the boxes. Each upload triggers an auto-detection of column mappings:

collar.csv: detected columns
  hole_id     → HoleID ✓
  east        → Easting (m) ✓
  north       → Northing (m) ✓
  rl          → Elevation (m) ✓
  total_depth → FinalDepth (m) ✓

If auto-detection misses a column (it shouldn’t on the sample), use the dropdown to map manually.

Click “Continue to validation →” at the bottom of the page.

Minute 3: Run validation

Click “03 Collar” in the sidebar. The validation runs automatically:

• ✓ 40 unique hole IDs
• ✓ All coordinates within project bounding box
• ✓ Elevation range 1,180 – 1,420 m (consistent with topo)
• ✓ Hole types: 35 DDH, 5 RC

Click through “04 Survey”, “05 Assay”, “06 Geology”, “07 Validation” — each runs in under a second on the sample dataset. You’ll see green checkmarks on the sidebar as each tab passes.

If you load your own data and a check fails, you’ll get a yellow warning row showing exactly which hole/sample is the problem. Click the row to jump to the offending record.

Minute 4: Generate strip logs

Click “08 Strip Log”. Pick a hole from the dropdown — try TRRC014. You’ll see:

• A multi-track strip log: Lithology, Weathering (Wx), AU, CU, PB, ZN, AS, FE, Sample intervals
• Depth axis on the left (0 – 100m, increasing downward — industry standard)
• Hover any track for tooltip with depth + value
• Dotted orange line on each grade track = P99 cap suggestion

Switch holes from the dropdown to compare. Multi-track strip logs are the fastest way to spot lithology-grade correlations and outlier intervals.

Minute 5: Generate a cross-section

Click “09 Section”. The sidebar lets you:

• Pick an azimuth (default: 0° = north-south projection)
• Pick a corridor width (default: 50m)
• Pick which holes to include

Click “Render section”. You get a 2D cross-section with:

• All holes within the corridor projected onto the section plane
• Lithology bands colored per code
• Grade highlights (configurable threshold)
• Topo line at top, hole traces inclined per dip

Change the azimuth slider — the section updates in real-time. This is where multi-hole correlation happens.

What’s next after Phase 01

Once you’re done with Drillhole Prep:

1. Click “12 Export” to dump your validated dataset as CSV (composited if needed)
2. Open Drilling-EDA.html (Phase 02) to run bivariate/multivariate analysis on the same data
3. Open Resource-Estimation.html (Phase 03) for variography + kriging

Each phase reads the previous phase’s export, so the workflow chains end-to-end without manual reformatting.

Loading your own data

Replace the sample CSVs with your project data. The required columns are minimal:

• Collar: hole ID, easting, northing, elevation, total depth, hole type (optional)
• Survey: hole ID, depth, azimuth, dip
• Assay: hole ID, from, to, value (one column per element)
• Geology: hole ID, from, to, lithology code

Column names can be anything — the auto-detector handles common aliases (HoleID / BHID / hole_id all work). If detection fails, use the manual mapping dropdown.

Common first-time questions

Does it work offline? Yes. The HTML bundles all assets (CSS, JS, fonts, sample data). After first load, no network needed.

Where does my data go? Nowhere. The file processes everything in your browser’s memory. No server, no upload, no analytics. You can run it on an air-gapped machine.

Can I share my project? Yes — export the validated CSV from Phase 01, send it to a colleague who has the same toolkit. They re-import and continue.

What if I have 10,000 holes? The toolkit handles up to ~50,000 sample records comfortably on 8 GB RAM. Beyond that, performance degrades. For mega-projects, split by domain or subset.

Browser compatibility? Chrome and Edge are best (V8 engine, fastest). Firefox works. Safari works but slower on large datasets.

What about commercial software?

Orebit is designed to complement, not replace, commercial 3D mining packages. The 80% of geology that happens before you fire up the workstation — data validation, EDA, top-cuts, compositing, basic kriging — is what Orebit handles. You can hand off the cleaned, composited dataset to your 3D package for final block modeling, mine planning, and reserves.

That said, for early-stage exploration, due diligence reviews, or quick scoping studies, Orebit’s three phases are often enough on their own.

Pricing

• Single module: IDR 49,000 (one-time)
• Full bundle (3 modules): IDR 99,000 (one-time)
• No subscription. No DRM. No license server. The HTML files are yours forever.

Bottom line

Five minutes from purchase to your first cross-section. No install, no friction, no data leaves your laptop. That’s the entire point of the toolkit.

If you hit a snag, email hello@orebit.id with your CSV (or a redacted version) and I’ll usually have a fix within a day. The toolkit is built by a working geologist, sold direct, and supported the same way.
