Acero-Martin resumes drilling at Pinaya

June 23, 2005

Acero-Martin Exploration Inc. has resumed drilling at its Pinaya property located in southern Peru. Drilling was temporarily suspended approximately three weeks ago to allow the continuation of the surface exploration program. The surface program entailed mapping, prospecting and trenching. Trenching has proved effective in locating new exposures of mineralized porphyry and in defining additional drill targets. During the last few weeks, the company has completed seven trenches totalling 707 metres and collected 283 samples. To date, the company has completed 48 trenches (new or rehabilitated) totalling 3,577 metres and collected 1,431 samples.

Mineralized porphyry has been exposed in the recently completed trenches. This information and that from prior drill holes will be used to locate future drill holes. PDH-17 (in-preparation) is to be located south of drill holes PDH-14 and 16. PDH-16 returned 90.5 metres of 0.68 per cent copper and 0.87 gram per tonne (g/t) gold. PDH-18, will be located south of PDH-15, returned 46.8 metres of 1.10 per cent copper and 0.32 g/t gold. Holes 15 and 16 are roughly 850 metres apart and are located west of the open cut.

Jeff Reeder, PGeo, and James McCrea, PGeo, are the qualified persons under National Instrument 43-101 for the Pinaya project, and are supervising the quality control and quality assurance program. Rock and core samples are transported to SGS Labs (a laboratory certified by International Standards Organization 9002) in Lima, Peru. Gold values are determined by 30-gram fire assay fusion with an atomic-absorption spectroscopy finish. All samples are also analyzed for 35 elements by ICP, total digestion, and those samples anomalous in copper are reanalyzed by atomic absorption (four-acid digestion). A quality control program of standards, blanks and duplicates is maintained.
