Investigator Silver has reported extraordinary silver grades well beyond the current Paris Project pit limits, including an eye-watering 1m at 13,302g/t Ag, alongside discovery of a new silver-bearing system at Theseus. These results could significantly expand the project's resource base ahead of planned follow-up drilling.
- 1m at 13,302g/t silver intersection outside DFS pit
- Multiple high-grade hits at Paris East and North
- New silver-bearing epithermal system discovered at Theseus
- Follow-up drilling of circa 30,000m scheduled
- Potential to grow silver inventory beyond current mining plan
Record-Breaking Silver Grades Outside Current Pit
Investigator Silver Limited (ASX:IVR) has delivered some of the most eye-catching assay results seen in recent Australian silver exploration, with a standout 1 metre intercept grading 13,302 grams per tonne silver from 80 metres depth at the Paris East prospect. This extraordinary hit is part of a broader 4 metre interval averaging 5,448g/t Ag, occurring well outside the margins of the Definitive Feasibility Study (DFS) optimised pit.
Other impressive intersections include 2 metres at 4,211g/t Ag from Paris North and multiple intervals exceeding 800g/t Ag. These high-grade assays were returned from the initial phase of the 2026 drilling program, which is targeting resource growth around the Paris Deposit and regional targets within the Paris Silver Corridor on South Australia's Eyre Peninsula.
Expanding the Paris Silver Inventory
The significance of these results lies in their location beyond the current DFS pit outline, which was released earlier in 2026. Managing Director Lachlan Wallace emphasised that the magnitude and grade continuity of these intersections could materially increase the available mining inventory, providing a clear pathway to expand the project's resource base.
Drilling has so far concentrated on the northern and eastern margins of the deposit, with further assays pending from Paris West and southern extensions. The company plans follow-up infill and expansion drilling to improve geological confidence and grade continuity, aiming to support future resource estimations and potentially enhance the project's economics.
Discovery of a New Silver-Bearing System at Theseus
In a compelling regional development, Investigator Silver reported the first-ever sampling of a preserved 2007 diamond drill core from the Theseus prospect, located less than 10 kilometres from Paris. Originally drilled for uranium, this core was never assayed for silver until now.
Sampling revealed multiple silver-bearing intervals, including 1.85 metres at 50g/t Ag, accompanied by lead and zinc mineralisation typical of epithermal systems. The hole ended in mineralisation, suggesting the system remains open at depth and laterally. This discovery opens a new front in the Paris Silver Corridor, with no prior drilling in the vicinity, presenting a fresh exploration opportunity.
District-Scale Drilling and Next Steps
Investigator is gearing up for an extensive circa 30,000-metre drilling campaign commencing in September 2026, designed to test both near-mine extensions and district-scale targets such as Alexander East, Manto, and Helen. While assay results from some regional targets remain outstanding, the current data reinforce the corridor’s prospectivity.
The company continues to advance its Mining Lease Application for the Paris Project, following a DFS that confirmed a maiden ore reserve and robust project economics. These drilling results arrive against a backdrop of strong silver prices and heightened investor interest in silver’s role in renewable energy and manufacturing.
Pending assays and ongoing drilling will be critical to defining the true scale and grade continuity of these discoveries, with the potential to reshape the Paris Project’s development trajectory.
Bottom Line?
Exceptional high-grade silver hits beyond the DFS pit and a new regional discovery at Theseus set the stage for a potentially transformative expansion of Investigator Silver’s Paris Project resource base.
Questions in the middle?
- How will pending assay results from Paris West and southern extensions influence resource expansion plans?
- What is the potential scale and grade continuity of the newly identified Theseus epithermal system?
- How might these drilling results impact the timing and scope of the Paris Project’s mining lease approval and development schedule?
