Trilogy Metals Inc. provided an update on metallurgical test work results for samples from the In-Pit Resource area of the Bornite Project, a part of the Company's Upper Kobuk Mineral Projects located in the Ambler mining district of Northwest Alaska. The defined In-Pit Resource contains 40.5 Mt of 1.02% Cu (indicated) and 84.1 Mt Cu (inferred) at 0.5% Cu cut-off grade. The objectives of this test work are to demonstrate that the Bornite mineralized materials are amenable to the production of high-grade copper concentrates using traditional mineral processing techniques and to determine the hardness and grindability of the mineralization. Results demonstrate that a high quality, 30% copper concentrate containing no deleterious metals can be produced. Furthermore, grindability test work conducted indicates an average Bond Work Index of 9.8kWhr/tonne, which is considered soft and therefore will have low grinding costs and power consumption. Test work has been completed at SGS Laboratories in Burnaby, British Columbia, which is independent of Trilogy Metals. Test work followed industry standard methods and procedures commonly used for the design and development of copper recovery processes, including hardness testing, floatation testing (lock cycle testing) and assaying of metallurgical products. The Bornite deposit is hosted in dolomite and typically contains approximately 5% to 15% total sulphide minerals including pyrite, chalcopyrite, bornite and chalcocite. Mineralogical evaluations conducted as part of this test work program show the copper minerals to display a wide variety of grain sizes. A majority of the copper mineralization is very well liberated at 100 microns, however, a minor fraction of the contained copper consists as very fine-grained copper sulphide minerals occurring in pyrite. The copper rich zones of the Bornite deposit do not typically contain significant precious metals and nor do the concentrates. Penalty elements in both the mineralized materials and copper concentrates are also low and below levels of concern. The mineralized materials were subject to grindability testing to determine power requirements in grinding. The materials were shown to be consistent with an average work index determination (Bond Work Index) of 9.8kWhr/tonne. Of the 15 individual samples tested, the variance of work indices was very low, with a minimum value of 8.8kWhr/tonne and a maximum value of 10.8kWhr/tonne. The Bornite materials are considered soft to very soft in terms of grinding power requirements.
