Grid Metals Corp (TSXV:GRDM) has obtained positive results from an additional five holes at its Donner Lake Lithium Property, located in the Bird River Greenstone Belt of southeastern Manitoba, Canada.
The holes are part of an ongoing resource delineation drilling program at the Main Dyke. All delineation holes from the current campaign have intercepted significant, high grade lithium values in the Main Dyke and, locally, in at least three proximal sub-parallel dykes that were not previously known.
Donner Lake is currently a 75% / 25% joint venture with Lithium Royalty Corp. Grid has an MOU in place with Tantalum Mining Corporation of Canada Limited focused on creating a toll milling operation to process spodumene-bearing pegmatites from Grid’s Donner Lake Property.
“We are pleased to see continued high-grade lithium values from our resource drilling at the Main Dyke, which is successfully tracing the Main Dyke to significant depth”, said Robin Dunbar, President and CEO of Grid. “The Main Dyke to date has been very consistent in the core ~800m resource drilling area. While we have many more exploration targets at Donner Lake we are currently focused on delineating an initial resource for the property from both the Main and Northwest Dykes.” he added.
Grid has now drilled 19 drill holes as part of the resource delineation drilling at the Main Dyke. Several other exploration holes have been completed to attempt to extend the strike extent of the Main Dyke and to provide an initial test of the mapped area occupied by the nearby Southwest Dykes.
Key findings to date include:
- Thus far the Main Dyke is showing excellent continuity of visible spodumene content within a core zone representing ~800m of strike length.
- Drilling is also locally encountering one or more narrower spodumene-rich pegmatites in the immediate (i.e., within <50m) hanging wall and footwall to the Main Dyke.
- Mineralization consists coarse-grained spodumene blades (see picture attached) and lesser quartz-spodumene (“SQUI”) intergrowths.
Programme Plans
Over the next ~two months, the Ccmpany plans to complete the initial resource delineation drilling program at the Main Dyke and the Northwest Dyke. The resource drilling at the Northwest Dyke will include infill and extension holes to augment results obtained from the 15 holes completed during the previous winter drilling campaign.
A number of exploration targets proximal to the Main Dyke and Northwest Dyke are also being assessed and could also be drilled before the conclusion of the current campaign. In particular, the southwest extension of the Main Dyke (south of diorite unit shown on the map, above) and the major gap area between the Main and Northwest dykes – which is low-lying, bog-covered and poorly exposed, are considered as immediate priorities for exploration drilling.
Other work currently being conducted in relation to the Donner Lake Property includes:
- a metallurgical test programme at the XPS laboratory in Sudbury, which is nearing completion;
- a drone magnetic geophysical survey to guide future exploration; and,
- integration of the 2022 field programme lithogeochemical sampling results with geophysical data to help guide future exploration activities.
Preparation of an Advanced Exploration Permit (AEP) application and associated environmental studies are ongoing with the application near completion. Approval of the AEP application would enable the company to complete a bulk sampling programme at Donner Lake. The bulk sample materials would be sent for processing at the nearby Tanco spodumene concentrator, as contemplated in the recently signed MOU with Tanco. The Tanco Mine is located approximately 50 km by road from the Donner Lake property and is currently Canada’s only producer of spodumene concentrate.
