Infrastructure Materials Corp. - Company Announces Drill Results at Silver Project

RENO, NV, April 20 /PRNewswire/ - Infrastructure Materials Corp. (OTCBB: IFAM) (the "Company") is pleased to announce positive drill results on the Nivloc Mine Project (the "Project"). Exploration of the Project is being conducted by International Millennium Mining Corp. ("IMMC") (TSX-V: IMI) under an option agreement with the Company's wholly-owned subsidiary, Silver Reserve Corp. ("SRC") (see the Company's press release dated February 28, 2011). Initial results of the diamond drilling program that commenced December 21, 2010, at the Project in Esmeralda County, Nevada include the following four gold (Au) and silver (Ag) intervals in hole 11NL-5:  (from 613.7 feet to 729 feet depth in the hole) 18.8 feet grading 7.10 oz/t Ag (ounces per ton), and 0.074 oz/t Au;  9.8 feet grading 13.74 oz/t Ag and 0.026 oz/t Au;  28.0 feet grading 8.05 oz/t Ag and 15.7 feet grading 3.29 oz/t Ag and 0.182 oz/t Au. A complete description of the intervals is set out in the following table.

Summary of Drilling Results

*True widths have not been calculated and are therefore not known

Six core holes totaling 6,791 feet (2070 meters) have been completed to test the in-place resource of the -55 degree NW dipping Nivloc vein system.  Four holes were drilled from Pad 1 situated some 1,000 feet NW of where surface traces of the vein are found.  The holes were directed toward the central part of the vein in the main 600 foot deep shaft area.  On completion of hole 11NL-4 the drill was moved to Pad 2, some 750 feet SSW of Pad 1, closer to the vein trace in order to test the West End deposit of the vein system.  Hole 11NL-5 intersected the true Nivloc vein and hit the four significant grade intervals of probable mining width mentioned above.  Hole 11NL-6, is visually interpreted by the IMMC's qualified person on site, to have intersected similar mineralization approximately 150 feet along strike to the NW from hole 11NL-5.  Assays are pending for hole 11NL-6.  Both holes 11NL-5 and 11NL-6 cut the dipping vein between the 440 and 600 mine levels.  Hole 10NL-1 encountered old mine workings in the hanging wall at 730 feet, went through the opening 10 feet and could not be advanced due to metal objects in the drift.

The Nivloc Mine project represents a quartz-adularia epithermal vein system where ore grade material was mined and milled from 1937 to 1943 by Desert Silver.  The operation was shut down during the Second World War by War Production Board Limitation Order L-208, when, in the interests of national defense, miners were ordered to stop mining precious metals in order to focus on strategic minerals such as copper.

The Nivloc vein system occurs in a structural zone up to 150 feet wide and over 4500 feet long and is considered to be a ring fracture feature associated with the Red Mountain caldera of mid-Tertiary age.

Interpretation of Drill Results

Thomas L. Evans, California Professional Geologist, and the Qualified Person under Canadian National Instrument 43-101 responsible for the drilling program, prepared, reviewed and approved the technical contents of this press release.  Mr. Evans advises that he believes that drill holes 11NL-2 & 3 were not drilled far enough to hit the true Nivloc vein.  These holes intersected good quartz vein material in the hanging wall that at first was thought to be the fault displaced Nivloc vein and thus were stopped short.  Hole 11NL-4 went farther and hit a strong quartz vein at 1267 feet to 1310 feet where the hole was lost.  The core size at that depth had been reduced to BQ which resulted in poor core recovery in the vein.  Any good values may have been ground up and washed out.

Holes 11NL-5 & 6, drilled from the more southerly Pad 2, intersected the true Nivloc vein at the projected -55 degree dip from its outcrop.  It is very encouraging that this portion of the projected West End deposit of the Ag/Au system, was not included in the report of a prior operator and consequently not mined by that operator.  .

Drill hole 11NL-7 has recently been collared from the new Pad 3, located 450 feet NW of Pad 2.  This new pad is positioned to follow the vein down dip and along strike in future drilling.  Hole 11NL-7 was designed to intersect the vein down dip from holes 11NL 5 & 6.

Based in part on these initial drill results, IMMC has commenced staking additional ground at the Project.

The drill assay intervals were calculated using the weighted average method.  Drill core analysis and assaying was conducted by ALS Chemex which is an ISO Certified laboratory.  IMMC 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.

Infrastructure Materials Corp. is an 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 in Nevada.
