Salvador (also called Bahia) is the capital. Gold Belt target area, 50 km north of Jacobina. This update reports the new drill results received for each of these target areas. Canavieiras To date, 44 holes totaling 5,005 metres have been completed at Canavieiras located 3 km north of the processing plant. Table 1 summarizes results of twelve (12) new drill holes at Canavieiras. Highlights are as follows: Extensions of Reefs Previously Mined - 21.62g Au/t (19.49 highs cut to 30g/t) over 2.6m true width in 9.9m (true width section) grading 7.04g Au/t (6.49 cut) in CAN-84 - 15.28g Au/t over 4.0m true width in 17.8m (true width) grading 4.67g Au/t in CAN-95 - 18.12g Au/t over a true width of 2.0m in CAN-89 - 17.57g Au/t (11.77 cut) over a true width of 1.4m in CAN-94 - 4.06g Au/t over a true width of 8.4m in CAN-88 Reefs Below Old Workings - 3.97 g Au/t (3.31 cut) over 15.4m true width in 31.5m grading 2.28 g Au/t (1.96 cut) in CAN-94 - 2.49 g Au/t over a true width of 20.9m in CAN-84 - 4.26 g Au/t over a true width of 5.8m in CAN-93 - 5.23 g Au/t over a true width of 4.4m in CAN-91 - 3.28 g Au/t over a true width of 6.4m in CAN-85 "The grades and widths that we see here continue to confirm and expand upon the excellent results obtained at Canavieiras earlier this year," commented Dr. Bill Pearson Pear·son , Lester Bowles 1897-1972.

A surface rig has just started drilling near the portal of an old adit about 230 metres south of the former Canavieiras Mine. The adit is being rehabilitated and serviced in preparation for underground drilling. As previously reported (see press release July 14, 2005) wide spaced historical holes returned significant results in the southern extension area including CAN-7, which intersected 10.42g Au/t (7.57g Au/t cut) over a true width of 4.8 metres. These historical holes confirm that the mineralization extends to the south but further drilling is required to fully evaluate the potential of this extensive target area that extends at least 600 metres along strike to the south from the existing old mine area. Drilling is also continuing from the new cross-cut at the southern end of the mine workings. The first two holes from this cross cut (CAN-95 and CAN-97) intersected east-west striking faults which significantly disrupted dis·rupt tr.v. dis·rupt·ed, dis·rupt·ing, dis·rupts 1.

Drilling is now being done from the eastern end of the cross cut to avoid problems with these faults. Hole CAN-88 which intersected 4.06g Au/t over 8.4 metres in the Piritoso and Liberino reefs is about 8 metres north of CAN-21 drilled in the 2004 program which intersected 8.0g Au/t over a core length of 13.0 metres in the Hollandez reef which is about 20 metres above the Liberino reef in the northern part of the old mine area.

Morro do Vento Extension At the Morro do Vento Extension area located immediately north of the processing plant, 19 drill holes totaling 7,985 metres have been completed of which new results are available for four holes as summarized in Table 2. Recent drilling has focused on exploring the southern continuation of the Basal basal /ba·sal/ (ba´s'l) pertaining to or situated near a base; in physiology, pertaining to the lowest possible level. ba·sal adj. 1. and Main reefs into the Morro do Vento area. The Main Reef, which is stratigraphically about 50 metres above the Basal Reef, is a major target that was intersected in the new drill holes and is the northern extension of the same reef in the Morro do Vento area that was previously mined. Highlights from new holes in the Morro do Vento Extension target include: - 3.84g Au/t over a true width of 7.1m in 14.4m (true width) grading 2.54g Au/t in Basal Reef in Hole MCZ-92 - 5.94g Au/t over 3.8m true width in Main Reef in Hole MCZ-91 - 3.51g Au/t over 4.9m true width in Main Reef in Hole MCZ-93 An underground drilling program has commenced at the Morro do Vento Extension area from the 630-metre level to test the potential for the Main Reef at shallower levels.

Northern Area (Pindobacu - Fumaca) To date, 30 holes totaling 5,991 metres have been completed in the northern area to test the Pindobacu, Entry Point and Fumaca targets. The drilling program in progress at Pindobacu where the majority of drilling has been completed (21 holes totaling 3710 metres) consists of several fill-in holes near hole PB-02 (5.46g Au/t over 21.9 metres) and a series of 100-metre spaced holes to provide a first drill test of the full strike length which based on geological ge·ol·o·gy n. pl. ge·ol·o·gies 1.

"Drilling is now being focused in this area to better define the centres of hydrothermal gold mineralization within this extensive altered system. Dr. Paul Karpeta, an expert on Precambrian conglomerate-hosted gold deposits has returned to Jacobina to review results of the Entry Point drilling (see press release July 14, 2005) and recommend additional drill holes to test the areas most likely to be channels with the thickest sections of coarser conglomerates A Conglomerate is the term used to describe a large corporation that consists of diverse divisions. Conglomerate companies tend to be large multinational corporations with operations in multiple regions of the world. ." At Fumaca, located 15 km north of Pindobacu, drill hole FN-06 that tested an area of strong silicification related to the northern extension of the Pindobacu Fault intersected 5.38g Au/t over a true width of 1.4 metres.

Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In addition, 'inferred resources' have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for Preliminary Assessment as defined under 43-101.
