Ampliacion Pueblo Viejo

The Ampliacion Pueblo Viejo concession is adjacent and to the north of Barrick's large Pueblo Viejo project, where reportedly, 14 million ounces of gold has been identified. Brigus has joint ventured this project to Everton Resources, wherein Everton has been granted an option to earn an initial 50% interest by making cash payments totaling US$700,000, incurring expenditures of US$2.5 million and issuing Brigus 1.2 million Everton common shares over a three year period. Upon reaching a 50% interest, Everton has an option to increase its ownership to 65% by incurring all expenses to the completion of a bankable feasibility study, and paying Brigus an additional US$2.0 million and 1.0 million Everton common shares.

Current Work

Recent exploration by Brigus has uncovered gold and silver mineralization in the La Lechoza area. An initial soil sampling program outlined areas of elevated mineralization identifying five separate zones of gold, silver, copper and zinc mineralization. Follow-up trenching within several of these zones has produced significant results, in particular from trench LT-10 where a zone of 18 metres graded 11.3 g/t gold and 310 g/t silver. A 1500 metre diamond drilling program has commenced to explore these targets.



Previous Brigus Exploration

During November 2003, the Company completed a trench and surface rock sampling program at the La Lechoza prospect on its Ampliacion Pueblo Viejo concession in the Dominican Republic and obtained results indicating an extension of near-surface gold mineralization 450 metres southeast of previous drilling and trenching. The results of trenching conducted perpendicular to previous soil sampling indicates anomalous gold mineralization can be viewed here.

Two rock samples taken from float material immediately past the end of the trench contained values of 0.8 grams per tonne gold and 4.0 grams per tonne silver, respectively. Trench samples were taken at a depth of 1.8 metres in saprolite (weathered rock) material with continuous chip channel samples taken at 2-metre intervals along the base of the trench wall.

The results indicate the extension of near-surface gold mineralization on an additional 400 metres in the updip direction from previous trenching and drilling by MIM and Rosario. The higher gold values in float-rock material at one end of the trench suggest the potential for additional grades in the subsurface below the saprolite (weathered) zone. The La Lechoza target area remains open in three directions.

Additional geologic mapping, soil geochemistry, rock chip geochemistry and a dipole-dipole induced polarization survey at the La Lechoza prospect indicate an anomalous area of 600 metres by 800 metres, which remains open to the south and northwest. Other targets also remain in other areas of the Ampliacion Pueblo Viejo concession where gold mineralization has been identified with little or no follow-up exploration.

Historical Exploration

Minera Mount Isa Panama won the rights to the Ampliacion Pueblo Viejo Fiscal Reserve as part of a privatization process held by the government of the Dominican Republic in 2001. Previously, this area surrounding the north and western sides of the Pueblo Viejo mining leases had been held under a fiscal reserve status which restricted exploration for the government due to its high potential for discovery of additional gold deposits.

Work by the government mining company, Rosario Dominicana, in 1981 on Brigus's Ampliacion Pueblo Viejo concession consisted of a program of 61 shallow (average depth 18m) holes in the La Lechoza prospect area. The results of this drilling can be viewed here.

During 2002-2003, Minera Mount Isa Panama conducted a program of stream sediment sampling, geologic mapping, soil sampling, and trenching at the La Lechoza prospect. Results indicated that the strike and dip extent of the zone of mineralization is larger than anticipated by the Rosario drilling (in excess of 800x600 meters) and is open to the south and northwest. Trench results along the most anomalous soil line show the following values:

Width	Cu	gAu
154 m including 54 m including 26m including 12m	0.2 0.3 0.4 0.5	1.6 3.3 5.2 9.8

A program of nine diamond drill holes was completed by Minera Mount Isa Panama in the anomalous areas during 2002-2003. The results can be viewed here.



A dipole-dipole IP survey was conducted over the anomalous trend and indicates a strong correlation of mineralization proximal to zones of high chargeability. The chargeability trend remains open to the south and northwest as does the gold anomaly from soil sampling.
