Drilling at Investigator Resources’ (ASX: IVR) Paris silver project has continued to confirm its very high-grade nature as well as expanding the known mineralised zones.
The company has received initial assays from 20,500m of infill drilling completed in December last year at the wholly-owned South Australian silver project.
Drilling was completed both north and south of the main 200m mineralised zone with assays now expanding the known mineralisation.
Investigator has previously described Paris as the highest-grade undeveloped primary silver project in Australia with a resource of 9.3 million tonnes at 139 grams per tonne silver and 0.6% lead for 42 million ounces of silver and 55,000t of lead.
Latest assays continue to confirm this theory with highlight intercepts of 3m at 718g/t silver from 28m; 1m at 783g/t silver from 28m; and 10m at 178g/t silver from 38m, including 7m at 299g/t silver from 38m.
These intercepts were 25m south of the main zone.
Around 75m north of the main zone, drilling hit 1m at 521g/t silver from 38m; 11m at 189g/t silver from 42m; and 9m at 142g/t silver from 45m, including 2m at 488g/t silver from 51m.
At 150m north of the main zone, Investigator struck 7m at 170g/t silver from 19m, including 2m at 288g/t silver.
Continuity of high-grade zones
Investigator managing director Andrew McIlwain said the latest results show “improved continuity” of some of the known high-grade zones.
“Importantly, the higher density of drilling will support and increase confidence in the resource estimate.”
Mr McIlwain pointed out that infill drilling completed in 2016 at the 200m main zone had resulted in a 37% increase in the inferred resource grade from 119g/t silver to an indicated resource of 163g/t silver.
He added this clearly demonstrated that as the confidence in the resource increases, so does the grade.
With recent assays “markedly above” the 2017 resource grade, Mr McIlwain said it was “really encouraging” for the project’s prospectivity.
Investigator is still awaiting assays from about 40% of the program and expects all results by April.
