Desert Sun Updates Drilling at Pindobacu in Bahia Gold Belt, Brazil

TORONTO, ONTARIO--(CCNMatthews - Nov. 21, 2005) - DESERT SUN MINING CORP. (TSX:DSM)(AMEX:DEZ) reports that it has received results for an additional 14 holes completed in the Pindobacu target area located 50km north of Jacobina. As previously reported (see press release November 3, 2005) the more recent drill holes at Pindobacu have tested the core area that extends at least 700 metres along strike at a deeper level (100m to 150m) than the original series of 100 metres spaced holes (50-80m).

Highlights from new holes at the Pindobacu target include:

- 23.63 (13.51 with highs cut to 30 g/t) over a true width of 2.5m in PB-30

- 3.11g Au/t over a true width of 8.0m in PB-27

- 3.02 g Au/t over a true width of 5.1m in PB-35

New results from drilling received to date are shown in Table1. Figure 1 is a plan map showing locations of the drill holes which have tested a total strike length of 1.3km along the mineralized structure.

"The new results continue to enhance the potential for outlining a significant gold deposit at Pindobacu," commented Dr. Bill Pearson, P. Geo., Vice President, Exploration. In the deeper series of holes, the silicified and mineralized zone is wider and more intense, however it is clear that the core of the hydrothermal system is likely deeper which will require further geophysical work and drilling to locate."

Based on drilling and detailed mapping at the Pindobacu, Entry Point and Fumaca targets the mineralized structure has now been traced over a strike length of 18 km and a new exploration model has been developed for the structural evolution and deposition of gold mineralization. Gold occurs as very fine grains of native gold associated with tourmaline within fractured, faulted and brecciated quartzites in the hinge area of a major fold structure. A 3-D model has been prepared combining geological information with the interpretation of the recently completed induced polarization (IP) geophysical survey that was prepared by John Buckle, P.Geo., consulting geophysicist. This model and down-hole IP surveys will be used to guide further drilling at Pindobacu in 2006.

Assaying for the program was carried out by Lakefield Geosol, an ISO 9001, 2000 laboratory based in Brazil, using fire assay on 50 gram pulps. Check assaying is routinely carried out, by ALS Chemex in Vancouver, on 10% of sample pulps and 5% of sample rejects. Independent standard reference samples are also inserted at regular intervals into each batch of analyses. Security is maintained at the core logging and sampling facility. Dr. Bill Pearson, P.Geo. is the Qualified Person as defined under National Instrument 43-101 responsible for the scientific and technical work on the exploration program.

Desert Sun Mining is a Canadian gold mining company listed on the Toronto Stock Exchange and the American Stock Exchange with 100% ownership of the Jacobina Mine and the 155 km long Bahia Gold Belt in the state of Bahia, in northeastern Brazil. Proven and Probable mineral reserves in the Jacobina Mine area are 17,620,000 tonnes at 2.11 g Au/t containing 1,200,000 ounces of gold. As a result of the Desert Sun's exploration programs to date, Measured and Indicated resources total 24,800,000 tonnes at 2.53 g Au/t containing 2,050,000 ounces of gold, and Inferred Resources total 22,200,000 tonnes at 2.61 g Au/t containing 1,900,000 ounces of gold. The mineral reserves are included within the Measured and Indicated mineral resources.

Readers are cautioned that any such statements are not guarantees of future performance and that actual developments or results may vary materially from those in these "forward-looking statements". This news release also uses the terms "measured resources", 'indicated resources' and 'inferred resources'. Desert Sun Mining Corp. advises investors that although these terms are recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and Exchange Commission does not recognize them. 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. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
