lithium/rare earth

The Big Mack and Separation properties were combined into the Separation Project in 2009 and Joint Ventured to Mega Graphite Inc. in May 2010.



The original property was staked and recorded in 1997 which was subsequently transferred in 1998 to Emerald Fields Resource Corporation, Kenora, Ontario. A block of 4 claims from the group was surveyed in 1999 - lease # CLM 428 also called the "Big Mack". Through approved amalgamation in 2008, the property is 100% owned by Pacific Iron Ore Corporation.


This 224 hectare (1 mining claim) mining lease is located approximately 60 km north of Kenora, Ontario in the Kenora Mining Division. The property hosts two primary pegmatites - the Big Mack and Zone Eleven. These pegmatites consist of a mixture of the rare-elements of petalite (lithium), tantalum and tin. Petalite is an important ore of lithium prized for its mineralogical properties. The mineral is a lithium aluminum silicate (simply lithium feldspar) which contains 4.9% lithium oxide.  It is especially valuable in imparting thermal shock resistance and has almost zero expansion when heated above 700C.  Products with 60%+ petalite can take direct flame and rapid water cooling without failure – stove tops and kitchen ware.  It’s environmentally friendly.  Requires less energy in manufacturing and produces reusable glass containers. Other lithium uses is found in pharmaceutical products and in batteries


The Big Mack pegmatite exposure is about 125 metres long by an average width of 30 metres. Diamond drill testing of 75 m length of the dyke to a vertical depth of 50 metres provided positive results. The 2001 drill program performed by Rodren Drilling Ltd., Winnipeg, Manitobe under the independent supervision of geologists A. Pryslak, P.Geol. and L. Chastko, P.Geol. of Manitoba. On averaging the core assays, the petalite content was 30.5 % on the samples taken.


Pacific Iron Ore sees the potential for significant petalite resource deposits within its Big Mack claim which will require additional drilling to confirm. Pacific Iron Ore does not plan any significant field work at its Big Mack claim prior to having a detailed 43-101 report completed in 2009.
