Common questions, straight answers

No. Orebit covers the workflow from raw drillholes to a report-ready estimate with full transparency. Commercial software is still needed for complex 3D implicit modeling, structural geology, and auditor sign-off. Orebit fits early-to-mid stage exploration, fast validation work, and small teams that can't justify a USD 30K/year license.

Yes. Output tables (assay validation, per-domain statistics, variogram parameters, M/I/I classification, grade-tonnage curves) align with KCMI 2017 Table 1. The auto-generated PDF carries the metadata auditors expect. Always cross-check with your Competent Person before final reporting.

Completely. Everything runs locally on your laptop — no server, no uploads, no external connections after download. Verify it yourself: disconnect from the internet, open the tool, everything keeps working. A full privacy audit log is in the docs.

CSV with comma or semicolon delimiters, dot or comma decimals. Indonesian Excel exports work out of the box. Column templates follow industry conventions for collar, survey, assay, and geology tables (Hole_ID, Depth_From, Depth_To, and so on).

Email hello@orebit.id. No ticket queue, no support bot — you reach the developer directly. Replies typically arrive within one or two business days.

Lean development with no enterprise sales overhead. Each module is a single self-contained tool — no servers to run, no licenses to enforce, no per-seat pricing. The savings go to the geologists using it, especially small teams and remote sites without budget for USD 30K licenses.

Yes. Once downloaded, Orebit GeoSuite works 100% offline. No internet connection required, no data leaves your laptop. Open the HTML file in any modern browser (Chrome, Edge, Firefox, Safari) and start working immediately.

Your data is saved automatically in your browser's local storage (IndexedDB). You can also export your project as a .orebit bundle file at any time. We recommend exporting regularly and keeping backups. Your original CSV files remain untouched on your computer.
