AURX Nzega-Igunga Gold Project

The AURX Nzega-Igunga Gold Project is a 685 km² district-scale land package in the Southern Lake Victoria Goldfield, controlling strategic infill ground between Barrick Gold's Bulyanhulu operation and AngloGold Ashanti's Geita mine — two of the largest gold mines on the African continent. The project sits within the Sukumaland Greenstone Belt, the highest-endowment goldfield in Tanzania, with combined historical and current production exceeding 30 million ounces.

A seven-channel, JICA-calibrated Bayesian prospectivity model has been completed across the tenement package, identifying ten priority banded-iron-formation-hosted gold targets (NZG-T01 through NZG-T10). The targets are prioritised for a ground-magnetic survey at 25-metre line spacing — higher resolution than the 50-metre standard recommended for BIF corridor definition — followed by first-pass RC drilling on the leading three targets.

The Sukumaland Greenstone Belt is a Neoarchean (circa 2.7 Ga) volcanosedimentary sequence comprising mafic-to-felsic metavolcanics, banded iron formations (BIF), chert horizons and clastic metasediments — the classic host stratigraphy for orogenic gold. The belt is dissected by crustal-scale shear zones that acted as conduits for gold-bearing hydrothermal fluids during late-orogenic deformation.

Two principal gold mineralisation styles are recognised across the belt: shear-hosted orogenic systems (the style at Bulyanhulu and Geita, hosting multi-million-ounce deposits) and BIF-hosted gold — where gold is concentrated within oxidised iron-formation units at the intersection of favourable stratigraphy and cross-cutting structures. AURX's Nzega-Igunga package targets both styles, with the priority NZG-T01 through T10 targets focused on BIF-hosted systems where recent advances in airborne magnetic and ground-gravity survey resolution have materially reduced exploration risk.

Three factors combine to define Nzega-Igunga as a high-conviction early-stage gold opportunity. First, district-scale land position — 685 km² is substantial by any measure and exceptional in the Tanzanian goldfield context, where most junior portfolios are under 100 km². Second, proximity to established operations and infrastructure — the project sits within haul-road distance of existing processing plants operated by adjacent majors. Third, a calibrated Bayesian prospectivity model trained on regional gold endowment, giving statistical robustness to the target ranking: NZG-T01 through T10 represent the top decile of P(Au) values across the entire modelled voxel grid.

• Seven-channel Bayesian prospectivity model calibrated against JICA regional dataset
• Ten ranked BIF-hosted targets (NZG-T01 through NZG-T10)
• Spatial coordinate audit (corrected +145 m East / +414 m North offset in legacy datasets)
• Interactive 3D voxel visualisation of all prospectivity layers
• Ground-magnetic survey design at 25 m line spacing (recommended over 50 m for BIF resolution)
• Full deliverable suite: KML, shapefiles, KMZ ground overlays, survey programme documentation

The near-term exploration programme comprises ground-magnetic survey across the top four target clusters at 25-metre line spacing, approximately 250 line-kilometres; soil-geochemistry infill on the magnetic follow-ups; trenching of any confirmed surface indicators; and first-pass RC drilling of NZG-T01 through T03, approximately 3,500 metres planned. A 0.5 to 1.0 Moz JORC-compliant resource target is achievable on the leading targets given successful drill confirmation.

Nzega-Igunga's combination of district scale and early maturity makes it an attractive vehicle for strategic investors seeking direct exposure to Tanzania's most productive gold belt. AURX will consider structured partnerships on individual targets or across the broader portfolio.
