Eureka Lithium starts field program at Raglan South Project, Quebec

Aug 23, 2023

Eureka Lithium Corp. owner of the largest lithium-focused land package in the top third of Quebec known as Nunavik, has commenced exploration at its 229 sq. km Raglan South Project which features a 20-km-long, 15-km-wide intense lithium geochemical anomaly. 

Eureka's 15-person field crew, headed up by GroundTruth Exploration, will perform grid-style prospecting and surface mapping across the entire land package at Raglan South sampling the historic pegmatite showings as well as any additional pegmatites found during the prospecting and mapping program. Samples collected during this program will be scanned and sorted in the field by using a handheld SciAps LIBS analyzer, with selected samples sent to the laboratory for analysis as a tool for identifying prospective zones and future drill target delineation.

A major tectonic boundary separates Raglan South, prospective for lithium-bearing pegmatites, from the Raglan Nickel Belt which hosts the world class Raglan mine approximately 80 km northeast of Eureka's property. Privately-owned KoBold Metals, funded in part by Bill Gates, Jeff Bezos and Richard Branson, recently completed a $195 million (U.S.) financing and is drilling for battery metals on its 929 sq. km land package that begins approximately 15 km north of Eureka's Raglan South (see Figure 1).

Raglan South Highlights:

  • Raglan South is part of the Superior Craton which hosts the majority of known lithium deposits in Canada including those in James Bay and Northwest Ontario. Raglan South is age dated at 2273 Ma, placing it in the U.S. Geological Survey's "sweet spot" for lithium deposits;
  • Raglan South has never been systematically explored for lithium until now, but includes an unusually strong lithium-cesium-rubidium anomaly in lake sediments based on 20 widely-spaced historical samples included in the Quebec government database;
  • Raglan South contains 12.3% of the 99.96 percentile lithium samples (<60 ppm) in lake sediments in the entire government database, with 7 samples >60 ppm and as high as 79.5 ppm lithium. Fourteen of the 20 Raglan South samples returned >37.3 ppm cesium (as high as 79 ppm cesium) while a 167 ppm rubidium sample is one of the top three rubidium lake sediment values in the government database;
  • Raglan South is flanked by a Bouger gravity low, indicative of an intrusive system at depth;
  • Very little geological mapping has been carried out at Raglan South but three units have been noted: 1) The Nantais Complex comprising several volcanic packages (metamorphosed mafic to amphibolite); The Lesdiguieres Suite (hornblende-biotite-tonalite with a magmatic, foliated or gneissic texture); La Chevrotiere Suite (porphyritic quartz monzonite granite);
  • Multiple pegmatites have been noted at Raglan South. 

Jeffrey Wilson, Eureka President and CEO, commented: "Raglan South is a very compelling target and for the first time this under-explored area will be investigated specificially for lithium-bearing pegmatites."

Wilson added, "Eureka has the largest lithium-focused land package in the top third of Quebec, a province that has fully embraced the push for new hard rock lithium deposits and associated infrastructure given the recent announcement that Ford and SK, a Korean battery manufacturer, are planning to build a new $1.2 billion battery cathode factory in Becancour, Quebec."
