Opus One Gold Corp. Obtains 4.12 g/t Gold Over 7.3 m at 135 m

NO-25-01 was drilled in the upper portion of the mineralized structure, a sector that had seen very limited drilling in the past. Zone 1 was intersected at a vertical depth of 115m below surface. Drill hole location and parameters are as follows:

Following our initial observations, it was decided to extend the originally planned 7,000 m drilling program to nearly 9,000 m (8,881 m). It totals 22 holes which have now all been completed. Logging and assaying are in progress. More assay results are expected soon.

Louis Morin, Opus One CEO, commented, "The first results of this drilling season are much better than anticipated. Those new results show that mineralized structure, near surface, is very strong and its thickness seems to increase from previous deeper intervals. Based on our preliminary visual review of the core, which indicated good evidences of mineralization (presence of an extended stockwork of quartz and sulphides), we decided to extend the drilling program as much as possible."

Sample preparation, analysis and QAQC program

All samples are described, labelled, cut (diamond saw) and bagged at Technominex' facilities in Rouyn-Noranda. Samples are then shipped to AGAT certified Laboratory in Val D'or for preparation. Sample pulps are then shipped to various AGAT laboratories in Canada for analysis. Samples are assayed for gold using by Fire Assay (50g), with ICP-OES Finish. All samples equal or above 10 g/t Au are submitted to ore grade gravimetric finish.

Opus One's QAQC program consists of one control sample inserted, at Technominex' facility, after 9 regular samples. Control samples consist of a certified blank and various gold grades certified material.
