Grid Metals Corp. (TSXV:GRDM) has received additional high-grade drilling results from the Phase 1 drill programme at its Donner Lake lithium property in south-eastern Manitoba, Canada.
In addition, the company has started field work at the Property that will initially focus on sampling of several previously mapped pegmatite dykes. The project is located in the Winnipeg River pegmatite field, which hosts the world-class Tanco pegmatite and the associated Tanco lithium-cesium-tantalum mine and concentrator. The project is a 75%/25% joint venture between Grid Metals Corp and Lithium Royalty Corp., a leading player in global lithium finance.
- New drill intersections of the Northwest Dyke include the following length-weighted average grades:
- 8.2 metres averaging 1.53% Li2O in GDL22-07 (from 103.5 metres) including 5.5 metres averaging 1.96% Li2O
- 14.6 metres averaging 1.25% Li2O in GDL22-11 (from 141.7 metres) including 5.8 metres averaging 1.74% Li2O
- 3.26 metres averaging 1.88% Li2O in GDL22-14 (from 178.8 metres)
- Anomalous cesium and tantalum values were also encountered in the new holes including maximum individual sample grades of 2850 ppm Cs2O (GDL22-11) and 509 ppm Ta2O5 (GDL22-10).
The Northwest Dyke has been traced by drilling for ~600 metres along strike and to a vertical depth of ~250 metres. It is the second drill-defined LCT type pegmatite with significant strike length on the Donner Lake property.
Similar lithium grades were previously reported for the company’s 2018 drill holes targeting the Main Dyke, which is located ~1.5 km to the east of the Northwest Dyke. Note that the Northwest Dyke intersection lengths reported above do not represent the true thickness of the dyke, which is estimated to typically range from four to eight metres, representing 50-70% of the reported intersection lengths.
Complete analytical results for hoes GDL22-07, -10, -11 and -14, together with drill hole specifications for these and previously reported holes, are provided in the Appendices accompanying this release. Hole locations are shown on the accompanying plan view map and longitudinal section. Core photos from the newly reported holes are included below.
Field Programme Underway
The company has mobilised geological crews to the property to sample the known pegmatite dykes on the property. Known pegmatite dykes include the West Dyke swarm, the South Dykes and several other pegmatites on the east part of the property that were mapped by Grid in 2012. A map showing the location of the target dykes is attached. Follow up work will include a lithogeochemical survey to vector to unexposed LCT type pegmatites.
The property is viewed by Grid as very prospective for other lithium bearing LCT type pegmatite dykes. The focus is on identifying new drill targets to complement the Northwest and Main Dykes which have been the target of drilling to date.
“We continue to see consistently good widths of high-grade lithium from the recent Northwest Dyke drilling,” Vice President, Lithium Exploration, Carey Galeschuk, said.
“In addition to our drilling we look to rapidly progress the Donner Lake discovery process with the identification of new drill targets in the field. With the combination of results to date, geological prospectivity and access to infrastructure we view the project as having great potential.”
