Silver explorer Investigator Resources (ASX: IVR) has continued to unearth “eye watering” grades at its Paris project in South Australia with one interval assaying 12,447 grams per tonne silver.
Latest notable results from infill drilling were 2m at 6,247g/t silver from 29m, including 1m at 12,447g/t silver; 29m at 534g/t silver from 45m; and 14m at 715g/t silver from 63m.
Drilling was also undertaken at the southern end of the Paris resource and uncovered 16m at 261g/t silver from 94m, and 19m at 181g/t silver from 43m.
All-up 20,500m of infill drilling has been completed at the Paris project, which hosts what Investigator claims is the highest-grade undeveloped primary silver deposit in Australia.
The existing resource is 9.3Mt at 139g/t silver and 0.6% lead for 42Moz of contained silver and 55,000t of lead.
Investigator managing director Andrew McIlwain said the drill results continue to support the company’s objectives of building confidence in grade and continuity of mineralisation.
He added seeing silver grades above the 2017 resource was “very encouraging” and that the hit of 12,447g/t silver outstripped what he had previously described as “eye watering” results.
“Additionally, in the initial assays from the first holes drilled in the southern part of the Paris resource have been returned.”
“Whilst incomplete over some intervals, reportable (closed off) mineralised intersections above 30g/t silver indicate the presence of broad mineralisation consistent with that noted in previous drilling,” Mr McIlwain said.
Advancing Paris silver project
Of the completed 20,500m of infill drilling, about 21,500 samples were generated.
Investigator has now received assays from about 4,500 of these samples.
“With a further 8,000 samples at the laboratory and the remaining 9,000 undergoing preparation at site prior to transporting to Adelaide, there will continue to be news flow for the next three months as analysis of these samples is finalised and a revised resource estimate is completed,” Mr McIlwain added.
Investigator is looking to develop a bulk open pit operation at Paris with latest drilling underpinning a pre-feasibility study.
The company is also refining the process plant flowsheet and design, as well as the proposed mine model. It is also evaluating the best power and water supply options.
