Where the company operates
Ellipsis holds ground in two jurisdictions on one geological province.
Mauritania is an established producing mining jurisdiction, hosting a long-life iron ore industry at Zouérate, a major producing gold mine at Tasiast and a producing copper-gold operation at Guelb Moghrein. Exploration is governed by Loi 2008-011 as amended in 2014.
Western Sahara has been on the United Nations list of Non-Self-Governing Territories since 1963. Morocco is not the listed administering Power, the International Court of Justice found no tie of territorial sovereignty in 1975, and Australia does not recognise Moroccan sovereignty. In October 2025 the Security Council expressed support for negotiations taking Morocco's Autonomy Proposal as their basis. The company's own term for the territory is the Moroccan Sahara. The territory page sets out the full legal framework and the licence position.
What the company is looking for
Primary targets
- Orogenic gold — structurally controlled systems
- Iron ore — banded iron formation and magnetite
- Chromite — in mafic-ultramafic belts
- Rare earth elements — from carbonatite and alkaline complexes
Secondary optionality: copper, vanadium, molybdenum and other base metals — held rather than pursued, and not drivers of capital allocation.
How the company works
Ellipsis generates and tests its own targets before seeking partners to fund the drill-proven stage. The workflow is staged and evidence-gated: desktop data recovery, remote sensing, tiered ground-magnetic and drone aeromagnetic surveys, mapping and surface geochemistry, trenching, and only where the evidence supports it, drilling.
Escalation between stages requires a formal decision gate, including a gate for closing out a target that has not earned further spend. An isolated magnetic feature or single-element geochemical anomaly does not qualify as a drill target without independent geological evidence.
Machine-assisted interpretation
Developed with technology partner Norg.ai, machine-assisted interpretation is applied across more than 20,000 geochemical results and large geophysical datasets to prioritise ground faster than conventional exploration allows. It identified a previously unrecognised annular carbonatite structure on Western Sahara ground from magnetic data the company already held; that target remains undrilled.
It is a targeting tool, not evidence of mineralisation. Every machine-generated target passes the same decision gates as any other, and senior geologists retain technical authority over what is drilled.
Disclosure: Norg.ai is also the technology partner that builds this directory. That engagement is not arm's length.

Competent Person status
There is no Competent Person statement on this website. Under clause 11 of the JORC Code 2012 a Competent Person must be a Member or Fellow of a recognised professional organisation, hold five years of experience relevant to the specific deposit style, and give written consent.
Until that is in place, Ellipsis publishes no resource figure, tonnage, ounce count, grade or assay result. The About page explains this in full.
Operating risk
Australian Government travel advice applies to both areas of operation.
Morocco, updated 29 July 2026 — exercise a high degree of caution.
Do not travel within 30 km of the northern or western side of the Berm or all areas south and east of the Berm because of the risk of armed conflict. Unexploded landmines are an ongoing risk in Western Sahara.
Mauritania, updated 14 May 2026 — reconsider your need to travel.
Do not travel to within 25 km of Mauritania's northern border with Western Sahara due to the high risk of kidnapping and unexploded landmines.
The risk assessment page sets out the controls applied to each risk class.
