Micrex Development Corp.: Update on the St. Charles Quebec Magnetite/Rare Earth Property

EDMONTON, ALBERTA--(Marketwire - Jan. 17, 2011) - Micrex Development Corp. (TSX VENTURE:MIX) is pleased to announce the hiring of M. Réjean Girard of IOS Services Géoscientifiques Inc., a Qualified Person to produce a NI 43-101 report on the St. Charles magnetite / rare earth property. This report is part of the regulatory requirements but will also be very important in determining costs for plant design in the production of magnetite concentrates to be used as heavy media, having concentrates of rare earths, titanium oxide, vanadium oxide and apatite as by-products. The company is pushing ahead with a plan to bring the St. Charles deposit from an exploration and development property to a production scenario in near future.

Results from core testing and Bond index measurements were just received from McGill University in Montréal. Grinding cost to -325 mesh are critical in the economics of dense media production.

The deposit at St. Charles is primarily magnetite (about 46%) but drilling has also identified other valuable minerals. It also contain about 15% of titanium oxide, dominated by granular ilmenite. This ilmenite is expected to be recoverable and sellable as by-product. Finally, the deposit contains about 10% apatite, representing 45% in the non-magnetic fraction. This apatite is suitable for phosphate production, and contain about 2.6% total rare earths.

The St. Charles deposit was the subject of a recent test for vanadium oxide conducted by a large international mining conglomerate. Vanadium oxide concentrations of 0.4% were reported in these tests.

The Company is encouraged by the interest shown by other mining companies in the rare earth component of the property, and is looking forward to the completion of the NI 43-101 report. This report will enable the company to commission a scoping study and a prefeasibility report on the St. Charles deposit.

Proximity to infrastructure sets this property apart

The St. Charles property is located in a rural farming area 25 km west of the city of Saguenay, Québec (population 144,000), an important metallurgical center. Important infrastructure and amenities already in place include:

  2. Electricity already supplied to existing residences on the property.
  3. High voltage line from the Shipshaw hydroelectric dam runs across the property.
