Right Resources Confirms Large RIRGS System at Pilot with High-Grade Core Untested

Right Resources’ drilling at the Pilot Project in Tumbarumba validates a large Reduced Intrusive Related Gold System, with assays highlighting low grades in the transitional halo but confirming the presence of a substantial mineralised footprint. The high-grade core remains untested, marking a key exploration focus.

  • Drilling confirms transitional halo within RIRGS framework
  • PhotonAssay reveals high nugget gold variability
  • Large mineralised system defined over 2.4km by 2.9km footprint
  • Higher-grade proximal Au-Bi-Te-W core remains untested
  • Third hole intersects major faults; assays pending

Drilling Validates RIRGS Model but Leaves High-Grade Core Untested

Right Resources Limited (ASX:RRE) has delivered a nuanced update from its Pilot Project in Tumbarumba, NSW, confirming the presence of a large Reduced Intrusive Related Gold System (RIRGS). Recent diamond drilling results from holes RRPT0001 and RRPT0004 have intersected gold mineralisation consistent with the transitional halo zone of the RIRGS model, characterised by low-frequency quartz veins with arsenic. However, the higher-grade proximal core; signalled by gold-bismuth-telluride-tungsten (Au-Bi-Te-W) mineralisation; remains untouched by modern drilling and represents the company’s prime exploration target.

PhotonAssay Highlights Nugget Gold Variability

The company’s use of PhotonAssay (PA), which analyses a larger sample mass than traditional 50g Fire Assay (FA), has revealed significant variability in gold grades; typical of nugget-style distribution. For example, in RRPT0001, PA upgraded some intervals by up to 307% compared to FA, with a maximum grade increasing from 5 g/t Au (FA) to 6.46 g/t Au (PA). This variability supports the interpretation that low grades in the transitional zone do not reflect the system’s true potential. The historic underground workings, which produced gold at around 38 g/t, underscore the presence of much richer mineralisation in the untested proximal zone.

Large-Scale Mineralised Footprint Confirmed

Together, RRPT0001 and RRPT0004 define a coherent mineralised system extending over approximately 70 metres of strike within a broader 2.4 by 2.9-kilometre footprint. The consistent As-Au geochemical signature and low-sulphide, sheeted quartz vein textures observed across these holes bolster the RIRGS interpretation. This sizeable system footprint suggests meaningful scale, but the true grade and continuity remain to be established pending further drilling and assay confirmation.

Structural Complexity Tested in Third Hole

RRPT0002, drilled to 1,400 metres, targeted a major northeast-trending fault corridor within the MTPR02 geophysical anomaly, interpreted as part of an intrusive complex southeast of historic workings. This hole intersected significant fault structures that may influence mineralisation distribution. Assay results from RRPT0002 are pending and will be critical to understanding the structural controls on gold mineralisation and refining vectoring towards the proximal high-grade core.

Ongoing Assay Validation and Next Steps

Right Resources is advancing additional assay testwork, including Screen Fire Assay (SFA), to validate PA results, especially near detection limits where accuracy declines. This step is vital to confirm the nugget effect and establish reliable grade estimates. The company also plans further drilling designed to test the proximal Au-Bi-Te-W zone, which remains the highest priority target. Meanwhile, collaboration with the University of Tasmania’s CODES group continues to refine the regional RIRGS framework and support metallurgical studies.

Bottom Line?

The Pilot Project’s large mineralised footprint and evidence of high nugget gold variability signal promising upside, but the untested high-grade core remains the crucial unknown for Right Resources’ next phase.

Questions in the middle?

  • Will assays from RRPT0002 clarify structural controls and improve targeting of the high-grade core?
  • How will Screen Fire Assay results affect the interpretation of gold grades near detection limits?
  • When will drilling commence to test the proximal Au-Bi-Te-W zone and what initial results can be expected?
