Chasing Bulk Tonnage Mineralisation In Ontario
Grid Metals Corp. (TSXV:GRDM)(OTCQB:MSMGF) has announced initial results from its recently completed spring 2021 drilling programme on its 100% owned Bannockburn Nickel Sulphide Property located in the Matachewan area of north-eastern Ontario.
The new drill programme is pursuing bulk tonnage disseminated nickel sulphide mineralization hosted by a three-kilometre-long serpentinized ultramafic body. The style of mineralization targeted is similar to that hosted in the Crawford Deposit owned by Canada Nickel Company.
Highlights
- Drill hole GBN21-02 intersected 296.5m averaging 0.28% nickel including a 112m section averaging 0.32% nickel
- The highest individual sample contains 0.43% nickel over a 1.5m core length
- The nickel-rich ultramafic host unit was intersected at the overburden-bedrock interface at a vertical depth of 37m and remains open to the east.
The company recently completed 2,785m in eight diamond drill holes distributed over a strike length of approximately 600m on the >1 km long B Zone trend of disseminated nickel sulphide mineralisation.
Hole GBN21-02 was one of two holes (GBN21-01 was the other) drilled from the same collar location across the strike of the B Zone trend.
Previous drilling and preliminary metallurgical studies on the B Zone confirmed the presence of heazlewoodite-dominant, secondary nickel sulphide mineralisation with similar mineralogical characteristics and nickel grades and thicknesses to that observed in the Main Zone at Canada Nickel Company’s Crawford nickel property.
Vice President of Exploration and Business Development, Dr Dave Peck, said the recent drilling programme at Bannockburn was designed to facilitate an initial assessment of the potential to develop a near surface, large tonnage nickel sulphide resource in excess of 100 million tonnes and containing over 200 kilotonnes of potentially recoverable nickel.
“We are encouraged by the nickel grade and thickness observed in hole GBN21-02. The new results confirm historical drilling results for this part of the B Zone,” Dr Peck said.
“We will soon start laboratory work that will determine the amount and type of nickel sulphide present – which is the most important piece of the story at the B Zone.
“Our target model is that the primary product from the B Zone would be a high-grade nickel concentrate for use in the EV supply chain. “
Dr Peck said additional drilling results will be reported over the coming weeks. When all results are in hand, the company will select samples for initial textural and mineralogical characterization to be followed by new metallurgical test work designed to estimate potential metal recoveries to a nickel concentrate.
A previous metallurgical programme on a composite sample from the B Zone found that 70% of the nickel in the sample reported to heazlewoodite, a secondary nickel sulphide mineral that contains 74% nickel and offers the potential to produce a very high nickel concentrate grade in the range of 25-35% Ni.
