Update on the St. Charles Qu�bec Deposit
February 14, 2011 - The deposit on this property is primarily magnetite, but it also contains substantial amounts of other important minerals. Average concentrations are magnetite (50%), titanium oxide (15%) and apatite (10%). The apatite percentage increases to 45% in the non-magnetic fraction, which makes separation very simple. Tests done on the concentrated apatite yielded rare earths in concentrations totaling 2.6%. Also, recent tests conducted by the in-house lab of a large international mining conglomerate yielded vanadium concentrations of 0.4%.
It is important to note that the titanium oxide is discrete and not intergrowthed in the magnetite, which makes it significantly easier to separate. Recent core analyses confirm the magnetite / titanium ratio to be constant throughout the length of the cores, and the same continuity applies to the various other elements.
Micrex has also commissioned a NI 43-101 report to bring the project current to this standard. Micrex expects the NI 43-101 report to be completed by mid March.
In view of this, Micrex has hired McGill University in Montr�al to test for the Bond Index of magnetite. They are currently running grinding tests to -325 mesh to determine the power consumption and time required to do this. This is essential to finalize the design of the plant to make heavy media for use in the water purification and metallurgical coal industries. Micrex intends to build this plant commencing early this year. In addition to the production of heavy media, concentrates of rare earths, titanium oxide, vanadium and apatite will also be produced.
The Micrex Magnetite projects will offer a secure, high quality source of supply to the wide range of industrial users desperate for magnetite produced locally.
