OREBIT · OPEN GEOSCIENCE TOOLS
Free tools for the work geologists do every day: checking drillhole data, reading the geology of an area, and testing a pit plan. Built by a practising geologist and Competent Person.
01 / THE PROJECTS
Each project states its scope and limits right next to its results.
Turn raw drillhole files into a traceable resource screen. Core validates and desurveys, Assay analyses and composites, Resource runs the estimate and the grade-tonnage curve.
Files stay on your computer. Use it in the browser, install it as an offline app, or run the Windows desktop edition. Results support technical review; they are not a Mineral Resource statement.
Read Indonesia’s geology on an interactive map. Switch between age and lithology, check the source behind every unit, and view the terrain in 2D or 3D.
Detailed Orebit layers cover Bangka-Belitung and Sumatra; Macrostrat fills the rest of Indonesia. Provisional classifications are marked on the map. GeoAtlas is not an official geological map.
See how a block model becomes nested pit shells, pushbacks and a period-by-period plan. Compare economics, sensitivity and a first-pass bench design.
The public demo shows precomputed synthetic projects. Run PitOpt on your own computer for your own block model. It is a strategic-planning prototype, not an approved mine design or an optimal schedule.
02 / START HERE
The same four steps work for every project.
GeoSuite for drillhole data, GeoAtlas for regional geology, PitOpt for pit planning.
See the projects ↑Work through a real public drillhole dataset, step by step, in English or Bahasa Indonesia.
Open the tutorials ↗Every GeoSuite screen, setting and method is documented, with a 15-minute quickstart.
Read the manual ↗Email a question, report a bug on GitHub, or support the work with a donation.
Get in touch ↓03 / MORE TO EXPLORE
Earlier projects and single-purpose utilities. Each runs on its own site.
R workflows for exploratory data analysis, variography and estimation.
Read the documentation ↗The first Orebit drillhole visualiser, built in R Shiny and hosted on shinyapps.io.
Open the app ↗Ten browser tools for plotting, quality checks and quick calculations.
Browse the utilities ↓Each link opens a separate site. PitDesign is a standalone utility, separate from PitOpt.
04 / THE PERSON BEHIND THE TOOLS
I’m Ghozian Islam Karami, a senior geologist and Competent Person under KCMI and JORC. I have spent more than ten years in exploration, resource modelling and mine geology in Indonesia. Orebit is where I turn the questions from that work into tools anyone can open and check.
05 / KEEP THE TOOLS FREE
There is no paid tier and no account. A donation of any size keeps the servers running and pays for new tutorials and features.
Donations are voluntary. They do not unlock features or change any licence.
