IMI International Millennium Mining Corp

Infrastructure Materials Corp. (OTCBB:IFAM) (TSX-V:IFM) (TSX-V:IFM.s) (the "Company") reports that its joint venture partner for the Nivloc Mine Project (the "Project") released assay results from four additional diamond drill holes at the Project. International Millennium Mining Inc. ("IMMI"), the Company's joint venture partner and a wholly-owned subsidiary of International Millennium Mining Corp. (TSX-V:IMI), is continuing its exploratory drilling at the Project under an option agreement with the Company's wholly-owned subsidiary, Silver Reserve Corp.

The results announced by IMMI are from holes 11NL-19 through 11NL-22, drilled from Pad 2 near the center of the zone, which tested previously undrilled portions of the deposit. The IMMI drilling program at Nivloc continues to expand the mineralized zone, which remains open at depth and along strike in both northeast and southwest directions.

The following highlights of Holes 11NL-19 to 11NL-22 were reported by IMMI:

Drill Highlight from hole 11NL-19:

16.8 feet @ 113.0 grams/tonne (g/t) Ag and 1.32 g/t Au - Main Nivloc vein

Drill Highlight from hole 11NL-20:

9.8 feet @ 173.0 g/t Ag and 1.78 g/t Au - Main Nivloc vein

Drill Highlights from hole 11NL-21:

200.8 feet @ 120 g/t Ag and 1.01 g/t Au – Main Nivloc vein, including:

9.0 feet @ 418.0 g/t Ag and 0.72 g/t Au - Main Nivloc vein, and

4.0 feet @ 731.0 g/t Ag and 8.61 g/t Au - Main Nivloc vein

Drill Highlight from hole 11NL-22:

8.2 feet @ 323.0 g/t Ag and 3.98 g/t Au - Main Nivloc vein

Drill hole 11NL-19 intersected the Nivloc vein system above the 440 ft level, in the eastern portion of the target area above the main haulage drift in the old workings. Drill hole 11NL-20 was a fill-in hole near the center of the target area and intersected the Main Nivloc vein system between the 600 and 700 ft levels. Hole 11NL-21 intersected the Main Nivloc vein between the 600 and 700 ft levels approximately 100 feet west of Hole 11NL-5. Drill hole 11NL-22 intersected the Main Nivloc vein system between the 600 and 700 ft levels and beneath the old workings in the eastern part of the target area. The level numbers referred to above, along with distances from other hole intercepts, are deemed to be approximate.

***Previous drill hole results are set out in the Company's February 22, 2012 Press Release.

The drilling program is focused on a target area that lies between previously mined zones within the northeast-southwest trending Nivloc vein structure. The exploration target lies between the surface and the existing 800 ft level drift in the old mine workings. The 800 ft mine level is approximately 900 feet vertically below surface and the vein and workings dip from -45 to -65 degrees towards the northwest. Previous mining at Nivloc focused on high-grade lenses of ore that were encountered while drifting along the vein structure. The IMMI drilling program indicates that the Nivloc structure ranges from 50 to more than 150 feet wide and contains several parallel vein zones. It appears from available data that only one of these parallel vein zones was exploited by prior mining activity. In addition to the potential for high-grade lenses similar to those that were mined historically, the material between the lenses is consistently mineralized to some degree.

It is stressed that no tonnage or grade estimates have been calculated to date. The current drilling program is designed to generate enough reliable information to outline viable mineralized zones that can be converted to resources in compliance with Canadian National Instrument (NI) 43-101 standards.

IMMI has increased the Project size by staking and adding 20 additional claims in April, 2011 and 73 additional claims in September, 2011, for a total of 122 claims covering approximately 2,280 acres. In addition, IMMI also reported that it discovered a decline on the Nivloc Mine property that is clean and structurally sound, measuring nine feet by nine feet and approximately 2,000 feet in length, ending within 170 feet of the historic Nivloc workings and approximately 80 feet above the 600 ft level. Together with the water rights, the county road through the property and power poles and lines already in place, this decline will be a significant factor when it is time to make decisions about the viability of bringing the Nivloc Mine back into production.

The drill assay intervals were calculated using the weighted average method. Drill core assaying was conducted by ALS Chemex, which is an ISO Certified laboratory. IMMI reports that it has implemented a quality assurance and quality control program to ensure that sampling and analysis of all samples is conducted in accordance with the best possible practices. The system includes the use of standards, blanks and duplicates to ensure analytical accuracy and the submission of duplicate samples to a second laboratory to verify the integrity of the analytical results.

Thomas L. Evans, California Professional Geologist, IMMI's qualified person under NI 43-101 in charge of the drilling program, reviewed and approved the technical disclosure of this press release.

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.
