Investigator Resources Ltd. said Sept. 23 that infill drilling is underway on the Paris silver deposit at its Peterlumbo project in South Australia, aiming to upgrade inferred resources of 33 million ounces of silver to the indicated category in preparation for a pre-feasibility study.
The program will comprise 6,250 meters of reverse circulation percussion, or RCP, drilling in 40 holes and 750 meters of large-diameter diamond core drilling in five holes that will twin specific RCP holes as part of the resource verification process.
Drilling is expected to be complete in mid-November to enable an updated resource estimate by early 2017. However, the program may be increased by a further 5,000 meters of RCP drilling should it be required to complete an indicated resource estimate.
If the second-phase, 5,000-meter drill campaign is carried out, it will be scheduled in the first quarter of 2017, with the updated Paris resource estimate to follow.
Investigator continues to assess various development options and scenarios for the deposit, including metallurgical and processing options such as either producing silver doré bars or a silver-lead concentrate. The company is also considering options for modular mobile processing plants, either owner-operated or using specialist third-party metallurgical process operators.
The pre-feasibility study is expected to be complete by mid-2017.
