XPS clay adumbrated added accessory of the abstracted concentrates is possible, including abridgement of nickel agreeable in the chestnut concentrate. Noront affairs to conduct connected pilot bulb testing assignment on afresh accomplished amount samples to affirm this modeling.
“These are important after-effects as they accredit us to accompany assorted business options for our concentrates,” said Noront President and CEO Alan Coutts. “Not alone can Noront advertise aerial affection articles to acceptable Canadian and all-embracing adorning companies, but we can additionally accommodate committed nickel concentrates to the arising array metals sector.”
2020 Metallurgical DrillingIn aboriginal 2020 Noront accomplished a metallurgical conduct attack to aggregate added sample absolute from the Eagle’s Nest drop for approaching airheadedness testing. Four holes totalling 642m were drilled, including two holes into the aerial area and two block holes into the lower domain. The aerial area holes were continuously assayed to bigger acquaint the adeptness model. The lower area holes were alone sporadically assayed to bottle acceptable absolute for approaching metallurgical testing. Table 2 summarizes appraisal after-effects of the aerial area holes and showcases the absurd metal tenor of the Eagle’s Nest sulfide ores. A blended photo of the massive sulfide circle in NOT-20-001 is apparent in Figure 1.

Ring of Fire Nickel ProspectivityThe brand of accepted nickel-copper-PGE sulfides in the Ring of Fire is commensurable to some of the richest nickel deposits in the world. The aerial tenor attributes of magmatic sulfides at Eagle’s Nest accompanying with the authentic altitude for accumulation of a abundant nickel drop presents a acute case for connected nickel assay in the region.
In 2019, the Aggregation completed a nickel targeting exercise which articular over 70 aboriginal date nickel targets in the Ring of Fire. The Victory target, staked in aboriginal 2020 was a artefact of this work. A afresh completed VTEM-plus assay over the Victory acreage articular several mid-time EM conductors associated with alluring targets of accessible ultramafic source. Noront is analytic aftereffect arena EM surveys to bigger boldness these targets advanced of drilling.
In addition, a thorough, absolute assay of the all-encompassing geophysical database will be commissioned to analyze ahead disregarded or undertested antecedence EM anomalies with nickel potential. It is account acquainted that the Company’s geophysical database in the Ring of Fire consists of over 130 aerial EM surveys, over 250 arena EM surveys as able-bodied as abundant added surveys of altered types (e.g., gravity, IP). Best of these surveys were completed by antecedent operators in the aboriginal canicule of Ring of Fire assay above-mentioned to our accepted compassionate of the cartography in the region. A re-evaluation of this all-encompassing dataset is appropriate and may crop a cogent cardinal of affection abstinent targets.
XPS Metallurgical Assay Assignment DetailEagle’s Nest is a high-grade nickel-copper-PGE deposit, amid in the arising mining arena accepted as the Ring of Fire in Northwestern Ontario. Noront filed an NI 43-101 adjustable abstruse address for this action in 2012, applying mineralogical and metallurgical assay assignment by SGS Lakefield.
The 2020 mineralogical and metallurgical assignment was commissioned to verify that marketable, abstracted nickel and chestnut concentrates could be able with adumbrative sulfide samples from the deposit. Open-circuit tests were acclimated to ascertain and tune the processes to aftermath a aggregate concentrate, constant with antecedent SGS assignment and to breach it into two concentrates via a break process. Locked-cycle tests were run to appraise the final action performance, based on a sample able by XPS. Since bank tests do not absolutely crop the after-effects that can be accomplished in a all-encompassing bulb with columns and re-circulating loads, XPS developed simulation software to appraisal the accepted final articles to be produced at the all-encompassing plant.
XPS acclimated absolute and blended samples that had been stored in SGS Lakefield’s freezer for the antecedent work. The action of this absolute was absolute by replicating the SGS action application the aforementioned celebrated alloy ratios of net-textured to massive sulfide acclimated by SGS to aftermath aggregate concentrates with agnate backdrop as the SGS work. XPS again acclimated absolute from the composites to adapt a new adumbrative blended alloy of 83:17 (net-textured to massive sulfide) to assay the revised action steps.
Test assignment with accessible circuits on the 83:17 alloy was done to clarify the breeze area and aftermath an bigger aggregate apply process. XPS again confused on to locked-cycle tests with the new 83:17 blended to aftermath a aggregate apply and again abstracted nickel and chestnut concentrates. The aggregate apply ambit produced abiding after-effects and yielded recoveries of 91.8% Cu, 83.1% Ni, 81.8% Co, 72.6% Ag, 86.1% Au, 85.0% Pd and 76.8% Pt into a aggregate apply with 5.1% Cu, 9.7% Ni and 31.1% S (Table 3). Importantly, the magnesium akin of the aggregate apply was 4.3% MgO.

Test after-effects of the copper-nickel break are apparent in Table 4. They announce abundant copper-nickel break is achievable. The empiric akin of nickel in the chestnut apply exceeds the affected bartering target, about this is a accepted affection of best copper-nickel break bench-scale testing. To affected this, XPS developed a proprietary modelling affairs to adumbrate metallurgical achievement at the bulb calibration based on bank calibration assay work. Table 5 summarizes the modelled copper-nickel break after-effects for the Eagle’s Nest 83:17 blended alloy and indicates nickel ethics beneath 1% in the chestnut concentrate, a key cold for bankable chestnut concentrates worldwide.
