TWO ADDITIONAL HANGING WALL INTERCEPTS AT NIVLOC PROJECT

RENO, NV, June 23, 2011 /PRNewswire/ - Infrastructure Materials Corp. (OTCBB: IFAM) (the "Company") is pleased to announce positive drill results from three additional diamond drill holes at the Nivloc Mine Project (the "Project"). Exploration of the Project in Esmeralda County, Nevada is being conducted by International Millennium Mining Inc. ("IMMI"), a wholly-owned subsidiary of International Millennium Mining Corp. (TSX-V: IMI) under an option agreement with the Company's wholly-owned subsidiary, Silver Reserve Corp. (see the Company's press release dated February 28, 2011).

Results from drill efforts on the Project include holes 11NL-8, 9 & 10, drilled from Pad 3, located approximately 450 feet west of Pad 2. Additional holes, including 11NL-14, just completed, and the re-drilled 11NL-12A have been drilled from Pad 3 as well. One more drill hole, 11NL-15, is now underway from Pad 3, after which the drill will be moved back to Pad 2 to target the 400 foot Level, which is above 11NL-5 & 6 and to the southwest along strike.

Drill Highlights from hole 11NL-8 include:
5.5 feet @ 0.43 gm/t gold (Au) and 293 gm/t silver (Ag) - Main Nivloc vein
5.0 feet @ 1.52 gm/t Au and 198 gm/t Ag; - Main Nivloc vein

Drill Highlights from hole 11NL-9 include:
3.6 feet @ 5.46 gm/t Au and 360 gm/t Ag; - Hanging Wall vein
27.6 feet @ 1.60 gm/t Au and 142.4 gm/t Ag; - Main Nivloc vein

Drill Highlights from hole 11NL-10 include:
7.5 feet @ 4.67 gm/t Au and 501 gm/t Ag; - Hanging Wall vein
42.5 feet @ 0.57 gm/t Au and 94 gm/t Ag - - Main Nivloc vein

Targeting the 650 Level area, hole 11NL-8 intersected the Main Nivloc vein some 200 feet west of 11NL-5. Hole 11NL-9 intersected the Main Nivloc vein approximately 320 feet southwest of 11NL-5, closer to the 700 Level. Hole 11NL-10 targeted the 790 Level area 215 feet vertically below and 320 feet southwest of hole 11NL-5. Hole 11NL-5, reported on in a prior release, contained four favorable grade vein zones of probable mining widths.

On June 14, 2011, the Company first announced the new Hanging Wall vein found in hole 11NL-6. This new Hanging Wall vein represents a previously unknown and un-mined vein. Of particular interest in today's reported results are two more encouraging intercepts on this now emerging Hanging Wall vein zone. Thus far the Hanging Wall vein has been intersected in holes 11NL-5, 6, 7, 9, & 10. Assays are pending for holes 11NL-11, 13 & 14 and hole 11NL-12A is being submitted for assay. Having completed 14 holes, IMMI is beginning to outline a possible Ag/Au block of mineralization measuring 400 feet along strike and 200 feet down dip, measured vertically.
