ASX-listed Neometals has reported encouraging outcomes from preliminary metallurgical check work achieved on mineralisation from the Armstrong deposit at its Mt Edwards nickel sulphide challenge about 35km south-west of Kambalda in WA.
The Perth-based firm says the preliminary “sighter” flotation check work factors to “industrial grade” nickel focus and materials palladium grades for the deposit.
Mt Edwards takes in roughly 50km of strike size over and across the world-class nickel sulphide-rich Widgiemooltha Dome construction, which has performed host to seven historic nickel mines, with Mincor Sources’ Cassini mine presently beneath improvement.
The most recent printed mineral useful resource estimate for Armstrong stands at 633,000 tonnes of ore at a median grade of two.1 per cent nickel for 13,200 of contained nickel, based mostly on a one per cent nickel cut-off grade.
For Neometals’ current flotation check work, samples of mineralised drill chips have been used from three RC holes accomplished by the corporate in late 2019.
Neometals says the check work carried out on the Armstrong main nickel mineralisation not solely pointed to the amenability of upgrading the nickel to acceptable focus ranges but in addition that the palladium restoration degree and grade within the check work might add to the income streams of any future industrial improvement. If palladium costs can maintain wherever close to their presently lofty ranges round US$2,600 per tonne, then they could possibly be appreciable.
In response to the Perth-based firm, focus grades for palladium and platinum present “vital encouragement” for the potential of those minority parts to contribute to income, topic to additional work.
The check work returned a 48.8 per cent restoration and an enhanced grade of 12.8 per cent for the nickel in focus and a 55.4 per cent restoration and a resultant grade of 20.4 grams per tonne for the palladium in focus.
Neometals Managing Director, Chris Reed stated: “This preliminary end result heralds a brand new chapter within the development of the Mt Edwards challenge. We’re thrilled to find the presence of palladium and platinum inside our already vital nickel endowment. We’ll pause our mining research and concentrate on a geometallurgical analysis to quantify the potential for vital co-product income.”
