Nortec Minerals Corp. is announcing that it has received positive metallurgical test results from representative core samples taken from the Kaukua Main Zone ("K-MZ") within the LK Palladium-Platinum-Gold-Copper-Nickel ("PGE+Au-Cu-Ni") Project ("LK Project") located in North Central Finland.
The test work was conducted by SGS Minerals Inc. of Vancouver, BC, Canada.
The preliminary test work on a blended representative composite of ore types concludes that conventional rougher flotation yielded substantial recoveries of over 80% PGE+Au, associated with recoveries of over 93% for Cu and 51% for Ni. The recoveries appear to be somewhat dependent on the host rock composition.
Cleaning this concentrate, again using conventional flotation means, produced a product assaying 16% Cu+Ni and 60 grams/tonne PGE+Au. Although this is not yet confirmed, a concentrate of this grade should be attractive to nickel and PGM smelters, especially given the low value of 4% Magnesium Oxide (MgO). This also means that the initially planned PLATSOLâ„¢ process for higher recoveries of PGE metals may now not be required. This will help lower the processing costs, simplify the project and reduce the technical risk of the project as a whole.
Further work is being planned for:
1) Optimization work for cleaner concentrate, with the addition of various amounts of the relevant reagents,
2) Tests and analysis to identify any other PGE associated metals like Rhodium, Iridium, etc.; and,
3) Marketing studies for the saleability of concentrate.
Nortec management is very pleased with these results as they validate the reasons for entering into option agreements for the claim groups initially with Akkerman Exploration B.V. for the Kaukua Group of claims in 2007 and the subsequent acquisition of the Haukiaho claims from Vulcan Resources of Australia in 2009. In comparison to other PGE+Au and Ni-Cu massive sulphide deposits, the concentrate from the LK Project has a much higher ratio of precious and base metals, producing a very high unit value per tonne of concentrate. This also favourably impacts infrastructure and transportation costs.
Mr. Chris Martin, Consultant to SGS Minerals, as Qualified Person (NI 43-101 Guidelines), approved the technical content on the metallurgical tests of this press release.
The present day metal prices for PGE+Au and Nickel-Copper are:
Palladium: US$417 per ounce
Platinum: US$1500 per ounce
Gold: US$1100 per ounce
Copper: US$3.00 per pound
Nickel: US$8.00 per pound
The K-MZ is located in the Kaukua Group that is one of the three groups of contiguous claims making up the LK Project, along with the Lipeavaara Group and Haukiaho Group. The LK project has a combined surface area of over 3,200 hectares and covers the PGE+Au-Cu-Ni mineralized Marginal Series hosted within a sequence of mafic and ultramafic layered intrusions.
Based on the current drilling information, the K-MZ mineralisation is open down-dip and along strike to the west and south. Furthermore, other targets have also been identified within the Property that could host commercial zones of PGE+Au-Cu-Ni mineralisation similar to the K-MZ in both size and grade. The Company believes that the LK Project can host several large-tonnage PGE+Au-Cu-Ni deposits amenable to low cost open pit methods. Drill results on the K-MZ can be referred to in the Company's previous press releases.
The geology and modes of mineralisation occurrence are similar to Goldfields' Suhanko Project (Arctic Platinum) situated 80 km to the west-northwest. Goldfields reported total resources (measured, indicated and inferred categories) at Suhanko to be 183 million tonnes grading 1.54 grams/tonne PGE+Au, 0.20% Cu and 0.08% Ni.
