- Further testing improves silver recoveries at Investigator Resources’ (IVR) Paris Silver Deposit in South Australia
- The company says metallurgical testwork was carried out at the main mineralisation, with results showing a 4 per cent improvement
- The weighted-average silver recovery at Paris now sits at 78 per cent, while recovery from the largest domain of the resource has jumped to 72 per cent
- The extra testwork, and previous drilling at the site, will help IVR create a new mineral resource estimate and pre-feasibility study for Paris

Further testing has improved silver recoveries at Investigator Resources’ (IVR) Paris Silver Deposit in South Australia.
The company carried out metallurgical testwork on the main mineralisation at the Paris deposit to try and improve on results from 2018.
It found the weighted-average silver recovery at Paris grew by 4 per cent to 78 per cent in total, while recovery from the largest domain of the resource also improved.
Testing from this Breccia Transitional (BT) domain saw silver recovery increase from 65 per cent to 72 per cent.
IVR said it was a significant result, as the BT domain material comprises of 54 per cent of the total 2017 Paris Mineral Resource.
Managing Director Andrew McIlwain explained it meant the updated Paris Mineral Resource was likely to show increased silver resources.
“We are very encouraged by the improved recoveries achieved in the met test program that focussed on the lower recovery material from the Breccia Transitional domain,” Mr McIlwain said.
“Previous testwork resulted in a 65 per cent recovery of silver from this material and, with the BT domain comprising 54 per cent of the resource, a clear opportunity existed to shift the economics of the project through improving the recovery of this largest metallurgical component of the resource.”
Along with extra testwork, IVR is also carrying out drilling at the deposit as it looks to create a revised Paris mineral resource estimate.
The company will then release a pre-feasibility study for Paris in the second half of the year, according to the MD.
“With the revised Paris Mineral Resource estimate anticipated to be available for ASX review in June, completion of this metallurgical testwork provides another vital component in progressing the Paris Silver Project PFS,” Mr McIlwain said.
Shares in Investigator Resources are trading up 4.76 per cent at 11 cents each at 10:42 am AEST.
