Greenstone setting
The Schweizer-Reneke Greenstone Belt is one of several Archaean greenstone belts preserved within the Kaapvaal Craton, comprising metavolcanic and metasedimentary sequences deformed into a narrow, steeply dipping corridor.
Regional exploration

Systematic regional exploration across a gold-bearing greenstone corridor roughly 4 km wide and 55 km long in the Kaapvaal Craton, North West province — the district that hosts our flagship Project Jerusalem.

Geological setting
An Archaean belt worked since 1903
Gold was first discovered in the Schweizer-Reneke district in 1903, and the belt has been worked intermittently ever since — largely by small-scale operations following surface expressions of mineralisation. Modern, belt-scale geoscience has never been applied consistently across the corridor, which is where our regional programme is focused.
Our approach is to build a single structural and geochemical picture of the belt, then convert the strongest targets into rights applications and standalone project studies.
Host lithology
Gold mineralisation is hosted primarily in siliceous banded iron formation (BIF) and associated quartz-carbonate vein systems, with magnetite enrichment marking favourable horizons.
Structural control
Mineralisation is strongly structurally controlled — shear zones, local bends and fold hinges act as fluid conduits, concentrating gold where deformation intensity is highest.
Limited outcrop
Scarce outcrop across the belt has made an accepted regional stratigraphy difficult to establish, leaving substantial ground under-explored by modern geophysical and geochemical methods.
Exploration workstreams
What we are doing on the ground
Literature and data compilation
Ongoing- Consolidation of historical mining and drilling records dating from the 1903 discovery
- Review of Council for Geoscience mapping and open-file reports
- Digitisation of legacy assay and borehole data into a single project database
Regional geophysics
Planned- Regional magnetic and gravity mapping of main structures and magnetite enrichment
- Seismic survey to define the deepest structures and channels
- Induced polarisation to detect associated sulphide mineralisation
Geochemistry and mapping
Ongoing- Soil and rock chip geochemical sampling on regional grids
- Field mapping of BIF horizons, shear zones and vein sets
- Target ranking against structural and geochemical criteria
Modelling and targeting
Planned- 3D modelling of rock structure and type from drill information
- Definition of hard boundaries, major faults and mineralised envelopes
- Drill target generation for follow-up prospecting applications
Target pipeline
From regional ground to a standalone project
01
Ground selection
Screening of open ground and third-party opportunities along strike from known mineralisation.
02
Desktop and survey work
Literature review, regional geophysics and geochemistry to rank targets before any drilling spend.
03
Rights applications
Prospecting right applications lodged over ranked targets, with the statutory environmental and biodiversity work packaged upfront.
04
Project promotion
Targets that survive first-pass drilling graduate into standalone projects with their own study programme, as Project Jerusalem has.
Global deposit analogues
Structurally controlled, BIF- and shear-hosted gold systems comparable to the Schweizer-Reneke Belt occur worldwide, and inform our targeting model.

Responsible exploration
Low-impact work, community first
Regional exploration is deliberately sequenced so that the lowest-impact work — desktop studies, geophysics and surface geochemistry — carries most of the decision weight before any ground disturbance. Landowner engagement, biodiversity assessment and rehabilitation commitments are built into every application we lodge.
