Grid Metals Corp. (TSXV:GRDM) (OTCQB:MSMGF) hassigned an option agreement to acquire a 100% interest in a previously undiscovered and prospective spodumene and lepidolite-bearing pegmatite lithium property located approximately 250 km northwest of Thunder Bay in Ontario.
The property hosts at least one highly fractioned and rare metal-enriched pegmatite dyke evidenced by high-grade lithium and highly anomalous cesium, rubidium and tantalum values obtained from Grid’s initial surface grab sampling.
Campus Creek Property – Highlights
- The Campus Creek property is located directly adjacent to the TransCanada highway and is road accessible with the initial discovery attributable to the recent logging in the area.
- Prospective geological setting for rare metal pegmatites, with property straddling a major tectonic boundary zone between three discrete structural domains in the western Superior Province
- No previous lithium or rare metal exploration; a bona fide new discovery
- Multiple fertile granite and granite pegmatite dyke outcrops identified by geochemistry over an initial reconnaissance prospecting area of ~4 km x ~2km
- Outcropping spodumene and lepidolite bearing pegmatite with high-grade Li2O contents
Whole rock geochemical analyses from a suite of ~80 outcrop grab samples consistently returned highly fractionated incompatible element ratios indicative of a fertile environment for rare metal-enriched pegmatites. The property remains poorly explored with only a handful of historic drill holes occurring in the existing claim block – none of which were drilled for rare metals. Initial analytical highlights for grab samples from the Highstone dyke are given in the table above.
Preliminary investigations indicate there are a number of granitic pegmatite outcrops on the Property with apparent widths locally exceeding 100 metres. The project occurs in a highly prospective geological environment centered on a major regional tectonic boundary.
The company believes the acquisition of a large land position with a highly encouraging initial lithium and rare metal occurrence, multiple outcropping pegmatite bodies and positive geochemistry is an exciting initial opportunity for Grid, particularly given the strong market fundamentals for lithium.
The company’s exploration model for a lithium pegmatite project is the discovery of a large zone(s) of spodumene-rich granite pegmatite from one or more dykes displaying strong and consistent mineralogical zonation and having highly fractionated geochemistry. Grid’s target tonnages are on the order of 10 million tonnes with grades exceeding 1% Li2O in a spodumene-rich resource capable of delivering a >6% Li2O spodumene concentrate.
In other news, Dr Julie Selway, a foremost expert in rare metal pegmatite geology and exploration approaches, has been engaged by the company to guide its ongoing exploration activities and provide interpretations on the results from initial due diligence work.
“I am excited to be involved in advising exploration work on this discovery. This is the first time spodumene and lepidolite have been identified on the Campus Creek Property,” Dr Selway said.
“The presence of both spodumene and lepidolite in the same pegmatite indicate a higher level of fractionation than a typical spodumene pegmatite. The spodumene in Highstone pegmatite is beige to pinkish indicating low iron content for future processing. The presence of fertile granites near the Highstone pegmatite indicates that there is a potential for more lithium pegmatite dykes to be found on the Property.”
The Company has commenced an initial geological mapping and additional outcrop sampling on the Property to map pegmatite occurrences and obtain additional geochemical information. Access to the property is very good via logging roads off the TransCanada highway. The sampling programme is expected to cost approximately C$50,000 and be completed over the next several weeks.
