MagIndustries Announces Updated Technical Report and Clarifies Previous Disclosure

  MagIndustries Corp. (the "Company") (TSX VENTURE: MAA) is pleased to announce that it has filed an updated National Instrument 43-101 ("NI 43-101") compliant technical report entitled "Updated Reserve and Resource Estimate for MagMinerals Kouilou Potash Project, Republic of Congo" dated June 10, 2009 (the "2009 Technical Report") in respect of the property held by its wholly-owned subsidiary MagMinerals Potash Corp.  The Technical Report updates the 43-101 technical report filed on December 1, 2008 (the "2008 Technical Report").

The 2009 Technical Report updates a number of areas in the 2008 Technical Report including, but not limited to:

- A minor decrease in the total reserve and resource estimates as a result of a change in the area available for the brinefield as a result of the finalization of the land use and occupation survey.

- The 2009 Technical Report indicates proven and probable reserves of 33.2 million tonnes of potash which can support a reserve life of more than 54 years at a projected production rate of 600,000 tonnes per year. The 2009 Technical Report estimates proven reserves of 151.2 million tonnes of carnallitite, at a carnallite grade of 64.4% of ore and a KCl grade of 17.3% of ore, concluding with proven reserves of 26.1 million tonnes of KCl. The 2009 Technical Report further estimates probable reserves of 40.3 million tonnes of carnallitite, at a carnallite grade of 65.7% of ore and a KCl grade of 17.6% of ore, concluding with probable reserves of 7.1 million tonnes of KCl.

- This compares to the 2008 Technical Report which indicated proven and probable reserves of 33.5 million tonnes of potash which could support a reserve life of more than 54 years at a projected production rate of 600,000 tonnes per year. The 2008 Technical Report estimated proven reserves of 155.0 million tonnes of carnallitite, at a carnallite grade of 64.2% of ore and a KCl grade of 17.2% of ore, concluding with proven reserves of 26.7 million tonnes of KCl. The 2008 Technical Report further estimated probable reserves of 33.2 million tonnes of carnallitite, at a carnallite grade of 63.9% of ore and a KCl grade of 17.2% of ore, concluding with probable reserves of 6.8 million tonnes of KCl.

- An increase in the estimated capital expenses of Phase 1 of the Kouilou potash project from US$723 million to US$835 million due, in part, to the inclusion of the 26 km gas pipeline between the Djeno gas treatment plant and the Kouilou project site, an increase in material costs (mainly an increase in the price of steel), and an increase in the indirect costs.

- An increase in estimated operating expenses of Phase 1 of the Kouilou potash project from US$83 per tonne of K60 to US$124 per tonne of K60 resulting from, among other things, an increase in the cost of natural gas, based on the finalization of a fixed-price (US$1.20/million BTU), 13-year gas supply agreement.

- An increase in the assumption of the base potash price for 2012 of US$649 from US$464 net realized price per tonne of KCl (based on current third-party potash price forecasts).

The overall recommendations of the authors of the 2009 Technical Report remain unchanged and they conclude that, using the base case, the Kouilou potash project's internal rate of return is estimated at 23% with the net present value estimated at US$914 million using a discount rate of 12%. Assuming total project costs of US$1.2 billion, pay back is achieved in approximately five years, assuming cumulative cash flows from operations for the period 2012 to 2016.

Clarification

In connection with the review by the Ontario Securities Commission (the "OSC") of the Company's amended and restated preliminary prospectus filed with the OSC and certain other provincial regulatory authorities on June 2, 2009, the Company has been requested to issue a press release in respect of certain of its previous disclosure relating to the Kouilou potash project (the "Project").

Specifically, the OSC has noted that certain of the Company's previously filed continuous disclosure documents did not include the grade information for each category of mineral resource and reserves in accordance with Section 2.2(d) of NI 43-101. In particular, the information contained in news releases of the Company dated December 29, 2008, March 26, 2009 and April 16, 2009, in the management's discussion and analysis of financial results for the year ended December 31, 2008, in the annual information form for the year ended December 31, 2008 dated May 27, 2009 and on the Company's website, which disclosed potash resource and reserve estimates without also stating the grade or quality and quantity for each category of the mineral resource and mineral reserve and is expressly prohibited by NI 43-101. Accordingly, such information should not be relied upon.

The Company hereby confirms that its current mineral resource and mineral reserve estimates at the Kouilou potash project are as set out in the following excerpt taken from the 2009 Technical Report filed on SEDAR at www.sedar.com on June 11, 2009.

The estimated resources of each category for Horizon 1, Horizon 2, Horizon 3 and Horizon 4 are presented in the table below. Already excluded from these resources are areas with geological and technical exclusion zones (approx. 35 % reduction) and mining losses assuming the use of a solution mining method have also been accounted for.
