Jellicoe Mine

"The Jellicoe is the most westerly mine in the Little Long Lac area with a record of gold production. The property is largely covered with overburden and the ore deposit was found by diamond drilling along the projected strike of a gold bearing zone at Magnet lake 1 ½ miles to the east on the property of Bankfield Consolidated Mines, Limited. In 1940-41 Jellicoe mined the whole orebody of approximately 14,000 tons, recovering 5,620 ounces of gold.The vein is in light-coloured greywacke. A mile-long dyke of fine-grained quartz feldspar porphyry 5 to 10 feet in width lies 100 feet south of the vein. A similar, even longer dyke lies 700 to 800 feet north of the vein. Some narrow diorite dykes are also rather closely associated. The porphyry dykes are gold bearing, but not ore. The vein material is quartz and silicified and brecciated greywacke. Mineralization consists of native gold, pyrite, arsenopyrite, and some sphalerite."
