Grid Metals Corp Reports Positive Metallurgical Test Results from Donner Lake Lithium Property
Grid Metals Corp Reports Positive Metallurgical Test
Results from Donner Lake Lithium Property
June 26, 2023 TORONTO -- Grid Metals Corp. (TSXV: GRDM ; OTCQB:MSMGF) (“Grid
” or the “Company”) is pleased to announce positive initial results from metallurgical
tests carried out on drill core samples from its 75% owned Donner Lake Lithium
Property. Samples were taken from the Main and Northwest Dykes that together are
the subject of an initial NI 43-101 resource estimate currently underway.
Mineralogical assessment and a bench scale metallurgical test program on composites
representing a number of the drill core intervals were completed at XPS Expert Process
Solutions, a GLENCORE Company, in Sudbury , Ontario (XPS). XPS is an experienced
provider of metallurgical testwork to the lithium industry. The mineralogical study
positively identified the main lithium -bearing mineral in the samples as spodumene,
the preferred mineral of concentrate feedstock for conversion facilities globally. The
bench scale metallurgical testin g produced excellent recoveries and marketable
concentrate grades.
Highlights from the program were as follows:
▪ Lithium recoveries (expressed as Li 2O) to concentrates of 76.9% (Northwest
Dyke) and 74.1% (Main Dyke) were achieved using standard grinding and
direct flotation methods.
▪ Both composite samples produced quality lithium concentrates - 6.2% Li2O for
the Northwest Dyke and 5.7% Li2O for the Main Dyke.
▪ Head grades (as Li 2O %) for the Main and Nor thwest Dyke composite samples
were 1.46% and 1.34 %, respectively, approximating average exploration
drilling grades obtained in Grid’s drill campaigns.
▪ Iron content of the concentrates was low.
▪ The mineralogical analyses completed as part of the testwork program found
that the main lithium carrier by grade was spodumene, which accounted for
89.3% of the lithium in the Main Dyke and 94.9% of the lithium in the Northwest
Dyke.
▪ The report was successful in recommending an optimal grind size to maximize
recovery from both of the Main Dyke and the Northwest Dyke composites.
▪ The report concluded that standard flotation was the best method for
recovering lithium from the samples. Testing of Heavy Liquid Separation, as an
initial evaluation of the Dense Media Separation process, was conducted and it
was determined that this process would not be of material value for enhancing
lithium recovery.
With a successful initial metallurgical program now completed the Company plans to
continue additional metallurgical testing in the future and has an upcoming program
of complementary metallurgical testwork to be completed at the Tanco Mine. The
initial work at Tanco will provide analysis of the potential recovery of Donner Lake
material from the Tanco lithium spodumene circui t. Tanco is one of two currently
producing lithium operations in Canada and Grid has a Memorandum of
Understanding with Sinomine Canada regarding toll milling of material from
Donner Lake at the Tanco Mine . In addition, the Company will follow up on
recommendations from the XPS report to complete variability testing on future
composite samples from the Main and Northwest Dykes.
“We are pleased to now have tangible met test results confirming that spodumene is
the dominant lithium mineral and that standard flotation processing appears to be
effective at recovering lithium to a marketable concentrate” said Robin Dunbar, CEO
of Grid Metals. This is another positive initial milestone for the Donner Lake Lithium
Property” he added.
Grid anticipates announcing the results of an initial resourc e estimate from the
Donner Lake Lithium Property in the coming weeks. The Company has also
commenced field operations to follow up on lithium exploration targets that were
identified by lithogeochemical data collected during the summer/fall field program in
2022.
