Idaho Champion Reports Positive Metallurgical Results from its Baner Project

TORONTO, June 06, 2019 (GLOBE NEWSWIRE) — Idaho Champion Gold Mines Canada Inc. (CSE: ITKO) (“Champion” or the “Company”), a discovery-focused gold exploration company, is pleased to announce that metallurgical work at the Company’s Baner Project returned favourable scoping level leach test results of 87.1% Au recovery at 10 mesh.  The metallurgical testing work was conducted by Resource Development Inc. (“RDI”), in Lakewood, Colorado.

Highlights of the metallurgical testing results are as follows:

  • Gold readily leached from the sample. Gold extractions ranged from 87.1% to 93.2% with higher extractions coming from the finer ground material. The majority of gold was extracted in the first 24 hours with slower kinetics observed with the 10 mesh leach test.
  • Little silver was extracted from the sample. Silver extractions ranged from 19.7% to 30.5%, which appeared to be independent of grind size.
  • Cyanide consumptions ranged from 0.19 kg/mt to 1.45 kg/mt, with the higher consumption coming from the finer ground material. Lime consumptions ranged from 3.4 kg/mt to 4.53 kg/mt.
  • Head analyses indicate that the composite sample contains approximately 1.0 g/mt Au and 2 g/mt Ag. There is virtually no organic carbon or sulfides present in the sample.
  • The gold present in the composite sample is free milling with extractions over 87% even at a coarse particle size of 10 mesh. A maximum gold extraction of 93% was achieved at 100 mesh and 200 mesh grinds, but with significantly higher cyanide consumption than observed at the 10 mesh particle size.

Jonathan Buick, Champion’s President and CEO, explains that: “The favourable leach test result compares to similar projects in North America and adds further positive understanding to Idaho’s newest gold discovery. We will continue with additional leaching test work to characterize the deposit. We will look at static leach tests with the coarse material to determine if heap leaching would be a reasonable processing option.”

Samples for metallurgical testing were split from drill core reject material returned from American Analyatical’s assay lab.  Twenty-five kilograms were split from four drill holes; IGC2018-6,9,10, & 13.  The split material was kept in a secure location until delivery to RDI in Lakewood, Colorado. 

Metallurgical Test Work  – Sample preparation and  Characterization

The primary objective of the metallurgical test program was to determine leach extractions of precious metals at various particle sizes.

RDi received twenty-three intervals of material for testing, at a combined weight of approximately 25 kilograms. The individual samples of material were inventoried and split in half to be combined to create a composite sample. The composite sample was stage crushed to minus 6 mesh utilizing a jaw crusher and cone crusher. The composite sample was then thoroughly blended, and representative 1 kilogram samples were split out for testing utilizing sample splitters. The description of samples that were used to create the composite are given in Appendix A.

Approximately 1 kilogram of material from the composite sample was split out for head assay. The material was pulverized and submitted for gold, silver, forms of carbon, forms of sulfur, and ICP analysis. The head assay results are summarized in Table 1.

Head analyses indicate that the composite sample contains approximately 1.0 g/mt Au and 2 g/mt Ag. There is virtually no organic carbon or sulfides present in the sample.

Bottle Roll Leach Tests

Cyanide leaching tests were completed with one-kilogram charges of the composite sample to determine precious metal extractions at particle sizes of P80 10 mesh, 100 mesh, and 200 mesh. The bottle roll tests were conducted with 1 g/L sodium cyanide maintained for 72 hours and at 40% solids and pH 11. Kinetic leach solutions samples and leach residues were submitted for gold and silver analysis. The leach results are summarized in Table 2.

About the Baner Project

The Baner Project is located within the Orogrande shear zone (OSZ), a 20-kilometre-long and up to 1 kilometre wide regional shear zone located in Central Idaho.  The OSZ resembles a series of grabens composed of metamorphosed Proterozoic belt sedimentary rocks, Cretaceous Idaho batholith intruded by Tertiary rhyolites and dacitic dikes.  The BC claim block covers a series of parallel shear zones on the eastern margin of the OSZ. Hydrothermal alteration is spatially associated with the OSZ and consists of silicification, seritization, and chloritization. Mineralization is hosted by three types of broadly defined deposit types; Tertiary epithermal deposits, Cretaceous intrusive related gold systems and orogenic shear zone deposits hosted within the batholith. Mineralization includes disseminated low-grade precious metal mineralization in associated stockwork veins, hydraulic breccias and extensive widespread alteration; high-grade gold associated with discreet structurally controlled quartz veins and silicified zones.

The Baner/Sally Project is in the central Idaho Gold Belt, 8 km south of Elk City, Idaho. Elk City is an historic gold mining region dating back to the 1860s and once supported more than 20 underground mines and extensive placer operations.  During the 1930’s there were three cyanide gold mills along Crooked River processing open pit and underground sulfide ore.  Exploration in the district during the 1980’s and 1990’s included Cypress-Amax, Kinross Gold, and Bema Gold primarily focused on near-surface bulk-tonnage gold potential. Premium Exploration conducted extensive drilling, soil sampling, and airborne and surface geophysics in the 2010 era. Currently a Finnish gold producer, Endomines AB is developing the Friday project at Orogrande into an underground gold operation and is constructing a gold processing mill.
