IMI International Millennium Mining Corp

Infrastructure Materials Corp. (OTCBB:IFAM) (TSX-V:IFM) (TSX-V:IFM.s) (the "Company") reports that International Millennium Mining Corp. (TSX-V:IMI) ("IMMC"), the option holder for the Company's NL Project, has announced an estimate of the mineralization at the Nivloc Mine Property (the "Estimate"). IMMC also announced that the Canadian National Instrument 43-101 compliant technical report from which the Estimate is derived will be filed on SEDAR no later than August 31, 2012.

The Nivloc Mine Property is situated in Esmeralda County, Nevada, and consists of 18 unpatented lode mineral claims (the "NL Project") owned by the Company's wholly-owned subsidiary, Silver Reserve Corp. ("SRC"), and 104 unpatented lode mineral claims owned by International Millennium Mining Inc. ("IMMI"), a wholly-owned subsidiary of IMMC (the "IMMI Property"). Pursuant to the terms of an option agreement dated February 25, 2011, IMMI has the exclusive right and option to acquire an 85% interest in the NL Project in consideration of payments to SRC of $350,000 and 1,925,000 shares of IMMC over a five-year period, with IMMI's interest in the NL Project vesting at the end of the period. If the Nivloc Mine Property is determined to be economically feasible based upon criteria described in the option agreement, SRC will be required to fund its portion of the operating budget in order to retain its 15% joint venture interest in the NL Project and to acquire a 15% interest in the IMMI Property. In the event that SRC decides not to fund its portion of the budget, its 15% interest in both the IMMI Property and the NL Project would be forfeited, but SRC would be entitled to a 2% net smelter royalty.

Infrastructure Materials Corp. is a Reno, Nevada based exploration stage mining company that is directing its efforts to the exploration and development, if warranted, of cement grade limestone deposits in strategic locations in the United States and Canada and precious metal properties located in Nevada.
