New gravity and continuous vat leaching recovery testwork on a Spring Hill ore sample has returned outstanding gold recovery, and reinforced previously reported assay upgrades for Thor Mining PLC (“Thor”) (AIM, ASX:THR) on its Spring Hill gold project in Australia’s Northern Territory.
Highlights of testwork results:
- 70.6% and 59.8% gravity recovery respectively for Hong Kong and Main zones.
- 98.3% gold recovery from combined gravity and continuous vat leaching of Main zones ore.
- Composite assays and process recovery support previously reported upgrade of fire assays to screen fire assay.
Thor commissioned Nagrom Mineral Processors, an independent metallurgical testing laboratory to assess potential gold recovery outcomes from gravity processing, followed by Continuous Vat Leaching as detailed below.
