Grid Metals Corp (TSXV:GRDM) has obtained promising results for the initial six holes of an ongoing exploration and resource delineation drilling programme at its Donner Lake Lithium Property located in the Bird River Greenstone Belt of south-eastern Manitoba.
The holes targeted the Main Dyke pegmatite and included intersections of 9.5m of 1.4% Li2O, 4.3m of 1.6% Li2O and 3.4m of 1.7% Li2O. Drilling has now covered a strike length exceeding 800m and to a vertical depth of up to 250m. Donner Lake is a 75% / 25% joint venture with Lithium Royalty Corp.
Highlights
- 29 drill holes completed to date at approximately 70 to 90 m step out spacing to a ~ 250m vertical depth on the Main Dyke and along over 800 m of strike length.
- Spodumene has been noted in all 29 drill holes completed to date.
- The Main Dyke is showing excellent continuity of visible spodumene content and lithium grades and is maintaining a near vertical orientation.
- Drilling is also locally encountering one or more spodumene-rich pegmatites in the immediate hanging-wall and footwall to the Main Dyke, such that the Main Dyke is now interpreted as a system of mineralogically similar LCT-type pegmatite bodies.
“The current phase of exploration is off to an excellent start. Our focus in the current programme is delineate the Main and Northwest dykes in order to establish an initial resource at the project,” President and CEO, Robin Dunbar, said.
“We will also be testing new exploration targets in the project area. We are looking to establish a ‘low footprint/high ESG credential’ resource amenable to toll milling at the operating Tanco Mine – Canada’ only lithium producing mine which is located 35km to the south of Donner Lake.”
Results to Date
To date a total of 29 drill holes have now been completed and six of those holes are reported here. Assays are pending for the other drill holes. The new drilling combined with the shallow holes completed in 2018 and previously reported by the company covers more than 800m strike length of the Main Dyke to an average vertical depth of approximately 200m – 250 m.
An important initial result from the resource drilling along the Main Dyke trend is the recognition of multiple, sub-parallel pegmatite dykes. Drilling to date has intersected three distinct lithium-enriched pegmatites including the Upper Main Dyke, which ranges from 1.00m to 9.93 m width, the Main Dyke, which ranges from 1.00m to 7.58 m in width, and the Lower Main Dyke, which ranges from 1.08m to 3.71m in width. Note that these widths represent the measured core length of the dykes and do not represent true widths.
Donner Lake Lithium Property
- The property is currently a 75% Grid / 25% Lithium Royalty Corp joint venture.
- Grid has signed an MOU with Tantalum Mining Corporation of Canada Limited ( Tanco ) with the purpose of establishing a toll milling operation (i.e., Grid mineralized material to be processed at the Tanco Mine).
- A metallurgical study is in process on samples from both the Main Dyke and Northwest Dyke.
- Year 1 baseline environmental field data collection has been completed.
- An Advanced Exploration Permit from the Manitoba government to enable bulk samples to be collected is expected be submitted during this quarter.
- A drone magnetic survey is currently being flown over the Donner Lake Property to assist in generating new exploration targets.
- Continuous engagement is occurring with the Sagkeeng First Nation on whose traditional lands the project is situated on.
