IMZ Reports New Drill Results at Inmaculada Project

Wednesday, May 5th, 2010

International Minerals Corporation (Toronto and Swiss stock exchanges – “IMZ” or the “Company”) reports new drill results from the Angela Vein at the 51%-owned Inmaculada gold-silver project, located approximately 25km southwest of IMZ’s 40%-owned Pallancata silver mine.
Several high-grade intercepts (estimated true widths) are reported in the latest drill results, including 3.5 meters (“m”) at an average grade of 35.1 grams per tonne (“g/t”) gold and 1,364 g/t silver and 3.1m at an average grade of 27.0 g/t gold and 490 g/t silver.
The new drill results have extended the Angela Vein mineralization for an additional 500m of strike length from 1,400m (as reported in the January 19, 2010 news release) to more than 1,900m, with a vertical extent of up to 300m (see Appendix 2). Mineralization remains open along strike to the northeast.
Assay results for all 47 core drill holes totaling 13,910m (Inma 88-134) are summarized in Appendix 1 and shown on the long section in Appendix 2. Assay results for 26 core drill holes totaling 9,499m (Inma 62-87) were previously reported in the January 19, 2010 news release.
Highlights of drill results from the 47 drill holes (all representing estimated true widths and average uncut grades) include:
– 3.5m at 35.1 g/t gold and 1,364 g/t silver (drill hole Inma-125)
– 3.1m at 27.0 g/t gold and 490 g/t silver (drill hole Inma-129)
– 5.0m at 19.9 g/t gold and 285 g/t silver (drill hole Inma-132)
– 4.6m at 12.5 g/t gold and 386 g/t silver (drill hole Inma-100)
– 7.0m at 9.2 g/t gold and 208 g/t silver (drill hole Inma-90)
– 12.5m at 6.8 g/t gold and 251 g/t silver (drill hole Inma-122)
The Angela Vein is one of several significant vein systems recognized at the Inmaculada Project, most of which are relatively under-explored.
In February 2010, an independent National Instrument (“NI”) 43-101 compliant mineral resource estimate on the Angela Vein (based on approximately 25,000m of drilling in 84 core holes) reported both indicated and inferred resources for the Angela vein, at a 3 g/t gold-equivalent cut-off grade (assuming a 60:1 silver to gold ratio), as follows:
– Indicated Resources: 1,238,000 Tonnes at 3.9 g/t gold and 122 g/t silver containing approximately 154,000 ounces of gold and 4.9 million ounces of silver (100% project basis)
– Inferred Resources: 4,686,000 Tonnes at 3.4 g/t gold and 147 g/t silver containing approximately 512,000 ounces of gold and 22.1 million ounces of silver (100% project basis)
An updated mineral resource estimate for the Angela Vein is expected to be completed by IMZ by the end of the second calendar quarter of 2010.
