Investigator Silver has reported a 10-metre silver intersection grading 2,662 grams per tonne from drilling around its Paris deposit in South Australia. The results strengthen the case for resource growth beyond the current DFS mine plan, but remain exploration-stage until further drilling and the planned 2027 resource update are completed.
- 10m at 2,662g/t silver from 78m, including 1m at 13,302g/t
- Further high-grade results from Paris East, Paris North, Paris West and Paris Deeps
- More than 12,000m completed from a planned 30,000m RC drilling program
- Drilling is targeting pit expansion, resource conversion and mine-plan improvements
- Updated Mineral Resource estimate targeted for calendar 2027
Paris drilling delivers another exceptional silver interval
Investigator Silver Limited (ASX:IVR) has produced one of the standout assay results from its 2026 Paris campaign, with hole PPRC968 returning 10 metres at 2,662 grams per tonne silver from 78 metres. The interval included 4 metres at 5,448g/t and a 1-metre sub-interval at 13,302g/t.
The result came from Paris East, around the margins of the pit design used in the project’s definitive feasibility study. It sits alongside a further 5 metres at 426g/t in PPRC965, 8 metres at 118g/t in PPRC969, 3 metres at 275g/t in PPRC970 and 7 metres at 143g/t in PPRC985. All reported widths are downhole lengths rather than confirmed true widths.
The release extends the run of unusually high-grade assays from the project, following the high-grade Paris hits reported earlier in the campaign. Those earlier results included the same 1-metre, 13,302g/t interval, which has now been incorporated into the company’s fuller reporting of PPRC968.
Results target growth beyond the current mine plan
Investigator has completed more than 12,000 metres of an approximately 30,000-metre reverse-circulation program that began in September. The work is testing extensions around Paris East, Paris West and Paris North, as well as deeper mineralisation beneath the current pit outline.
At Paris North, PPRC957 returned 4 metres at 2,119g/t from 111 metres, including 2 metres at 4,211g/t and 1 metre at 8,120g/t. Paris Deeps produced more moderate but still significant intersections, including 6 metres at 111g/t from 256 metres in PPRC929 and several shorter intervals in PPRC931.
The company says drilling is intended to improve confidence in existing Inferred Resources, support conversion to the Indicated category and test whether the pit could be expanded. Infill drilling is being brought towards a nominal 25-metre by 25-metre spacing in parts of the deposit, a step aimed at supporting future resource estimation rather than immediately changing the mine plan.
Regional targets offer a more mixed signal
The results were strongest close to the established Paris deposit. Regional drilling at Alexander East returned minor silver intersections, including 3 metres at 20g/t, while no significant silver intersection was reported from the latest Manto holes. Helen produced a 3-metre interval at 19g/t, below the 20g/t reporting threshold used for the main Paris results but above the regional 10g/t threshold.
That contrast matters: the current announcement supports continuity and potential expansion around a known high-grade system, but does not establish a second comparable deposit across the wider Paris Corridor. Some assays remain outstanding, and several reported boundaries are open to change when adjacent results arrive.
Drilling continues ahead of a 2027 resource update
Investigator plans to continue infill drilling within part of the proposed starter pit, extension drilling around the DFS pit margins and exploration of priority regional targets. The company is targeting an updated Mineral Resource estimate in calendar 2027, which is expected to inform any assessment of changes to the pit design and mine plan.
The immediate question is whether these spectacular grades can be demonstrated across enough width, continuity and tonnage to alter the economics of the existing project. Until the remaining assays, follow-up drilling and resource work are complete, the 10m at 2,662g/t is best read as a powerful exploration result rather than a revised reserve or production forecast.
Bottom Line?
The assays add weight to a potential Paris expansion, but the investment case still turns on continuity, resource conversion and the 2027 mine-plan review.
Questions in the middle?
- Will follow-up drilling confirm that the highest-grade intervals continue across sufficient width and strike?
- How much of the Inferred Resource around the DFS pit can be converted into the Indicated category?
- Could the 2027 resource update support a materially larger pit or mine plan after outstanding assays are incorporated?
