Mechanical Sorting Tests Result in Significant Upgrades at Novo’s Beatons Creek Project
VANCOUVER, British Columbia, Jan. 29, 2020 (GLOBE NEWSWIRE) — Novo Resources Corp. (“Novo” or the “Company”) (TSX-V: NVO; OTCQX: NSRPF) has recently conducted laboratory-scale mechanical sorting tests on Beaton’s Creek bulk sample material at Steinert Global’s (“Steinert”) Bibra Lake and Canning Vale testing facilities in Perth, Western Australia. Initial test results are discussed in this news release.
Highlights:Nuggety gold occurring in Beaton’s Creek conglomerates is finer grained (generally sub 1 mm) than gold at Novo’s Egina and Karratha projects (generally over 1 mm). Nonetheless, initial laboratory-scale tests indicate an upgrade of gold into significantly reduced mass is achievable.Test work was conducted on a 2.8 tonne split of crushed (-50 mm) and screened Beaton’s Creek bulk sample material. Analyses conducted as part of this sorting test work generated a calculated head grade of 5.72 gpt Au for the bulk sample. The vast majority of gold reported to mechanically sorted concentrates in each of the three size fractions tested (please refer to summary below). An impressive 90.2% of gold was recovered in 54.5% of the mass of the +18/-50 mm fraction, 68.8% of gold was recovered in 42.4% of the mass of the +6/-18 mm fraction, and 95.5% of gold was recovered in 20.3% of the mass of the +2.3/-6 mm fraction. Material finer than 2.3 mm, comprising 17% of the total mass of the bulk sample, was not tested due to excessive dust issues. Novo believes such material is treatable by means of gravity concentration.Test results are considered indicative, and Novo and Steinert see additional opportunity to optimize sorting conditions and parameters that may result in further efficiencies. Nevertheless, these tests indicate robust potential for upgrading nuggety conglomerate gold mineralization, and perhaps, a broader spectrum of gold mineralization types.A second 2.8 tonne split of the same bulk sample material has been delivered to TOMRA Sorting Pty Ltd’s (“TOMRA”) mechanical sorting test facility in Castle Hill, New South Wales where it will soon undergo similar testing utilizing various TOMRA mechanical sorters.Summary of mechanical sorting test results from a 2.8 tonne Beaton’s Creek bulk sample:
