Iron Ore DepositSUNI TOWNSHIP – Iron Deposit
(aka. Central Onaman Range Prospect)
Class: Iron formation, Algoma type, oxide facies.
Location: Between Castor and Jeffries lakes, W central part of Suni and E central part of Oboshkegan townships, Ontario, Canada. Reference: ODM map 18c.
Description: Two parallel bands, striking N75W, of magnetite-quartz (jasper, chert) iron formation with intercalated greywacke, each 100 to 350 feet wide and separated by 100 to 1000 feet of greywacke. Hosted within Archean metavolcanics. The north band comprises the West, Middle and Jeffries zones, the south band includes the Jeffries zone and the “C” zone to the west.
Economic Features: The central range contains 100 million tons proven and 100 million tons of indicated reserves (NI 43-101 non-compliant). This includes an ore body 3,200 feet long and 800 feet wide, with an "island" of waste 1,300 by 300 feet, outlined in the Jeffries zone which contains 60 million tons to a depth of 600 feet averaging 22.5% mag.Fe. Composite bulk samples from 2 pits grade 29.7% Fe. By wet magnetic methods and grinding to 88.90% -325M, a concentrate assaying 66.5% Fe, 6% Si02 has been produced with a mag. Fe recovery of 94% (i.e. 3.14 tons crude yields 1 ton of concentrate).
