About Orex

We read the shape of the land, and tell you what it can and cannot prove.

Exploration decisions get made on scattered data. A geological sheet in one place, a licence boundary in another, satellite imagery somewhere else, and assay results sitting in a spreadsheet nobody has gridded. Orex brings those together and does the reading.

The core of it is structure. Satellite elevation data covers the whole planet, and the faults and fractures that carried mineralising fluids often leave a trace in the terrain. We map those traces, then cut a cross-section through every one of them to see whether there is real relief there or whether it is a road. What survives that check is worth your attention. What does not, is not.

Measured, not drawn

Every lineament is profiled against the terrain and reported with the relief it actually has.

Published sources

National geological surveys, licence cadastres and open satellite missions — cited, not hidden.

Reports you can defend

Every report ends by saying where its numbers came from and what they do not mean.

Built for the field

Coordinates in the formats a handheld GPS takes, and an app that works where the signal does not.

What It Does, And What It Doesn't

Remote sensing attracts a lot of overclaiming. Here is the line we hold.

What Orex does

  • Maps terrain lineaments from satellite elevation data, anywhere on Earth
  • Cuts an elevation profile across each line and reports the relief it finds
  • Flags where structures cross, and how consistent the fabric is
  • Reads published geological maps under your licence boundary
  • Turns your own assay results into a hot-spot map with ranked targets
  • Writes it all into a report that says where every number came from

What Orex does not do

  • Detect gold, or any other metal, from orbit
  • Confirm that a lineament is a fault — only the ground does that
  • See structures buried under soil or alluvium with no surface expression
  • Replace sampling, geophysics, mapping or drilling
  • Produce a resource estimate, or anything a competent person would sign
A tool that tells you what it cannot see is more useful than one that pretends it can see everything. Structure narrows where to look. Rock type and geochemistry decide which mineral system, if any, is relevant. Your assays settle it.

How We Work

The approach, the sources, who it is for, and who is behind it.

Evidence first

We do not ask you to trust a black box. Every line on the map can be traced back to a measurement, and every report explains how its numbers were produced.

Limits stated on the page, not in the footnotes
Scoring used to rank, never to conclude

Lineaments classified by how they sit in the terrain

Built on published data

The inputs are open, documented and checkable. You are working from the same sources national surveys and space agencies publish — not from a private dataset you have to take on faith.
