JACOBINA GOLD MINE NEARS COMPLETION – FIRST GOLD POUR SCHEDULED FOR APRIL

Desert Sun also provides an Exploration Update

DESERT SUN MINING CORP. (TSX:DSM, AMEX:DEZ) continues to make significant progress toward gold production from the Jacobina Mine and is pleased to report that the first gold pour is scheduled for April 2005. Desert Sun is on track to complete the project on schedule and on budget and to produce gold at a steady state of 100,000 ounces per year in the third quarter of 2005.

The reactivation of the Jacobina Mine continues at a rapid pace with the processing plant construction and automation essentially complete. The crushing plant, ball mill and CIP (carbon-in-pulp) circuit are all operational. Low grade ore from previous mining was fed into the plant beginning in January and 18,000 tonnes have been processed so far. Processing of development ore, of which approximately 71,000 tonnes had been stockpiled to the end of February, will begin in early March.

“The success we have achieved in reaching our milestones has put us on schedule for a gold pour in April,” commented Bruce Humphrey, President and CEO of Desert Sun Mining. “This is a testament to the skill and expertise of the individuals who are dedicated to this project and have been driving it forward.”

Progress to date on the processing plant and mine include:

The conveyor and pumping systems are operational

New leach tanks have been erected and have completed hydraulic testing

Gold refinery electrowinning equipment is in place

The refinery’s induction furnace has arrived on site and is currently being installed

Compressors and back-up generators are commissioned

The tailing facility is complete

The assay laboratory is complete and currently in use

Mining equipment required for start-up is on site

The remaining fleet of required haulage trucks will be delivered during the second quarter of 2005

Simba long-hole drills are now operational underground with Desert Sun crews and Atlas Copco trainers

Ramp development is underway and making excellent progress

The mine ventilation system and compressor plant are operational

The new repair shop and mine offices are in use

Desert Sun has completed over 7,000 hours of staff training on mine equipment and safety procedures and has maintained an excellent safety record

The newly-formed Mine Project Group is preparing budgets for advancing the exploration and development in the Jacobina South Extension, Morro do Vento, Canavieiras, Serra do C6rrego and the Morro do Vento Extension. This is anticipated to encompass expenditures of approximately US$5 million in addition to the previously reported exploration program of US$5 million (Desert Sun press release dated January 19, 2005).

Exploration Update

Desert Sun has initiated a major exploration program for 2005, which will include at least 25,000 metres of diamond drilling. This program will focus on further exploring and developing major targets in the Jacobina Mine area as well as significantly expanding the exploration work in the northern area of the Bahia Gold Belt, especially at Pindobaqu. Results of exploration work, including drilling, will continue to be released on a regular basis as results become available.

Work in progress on exploration is as follows:

One surface drill is testing the downdip and on-strike extension of the Basal/Main Reefs in the Morro do Vento Extension. Hole MCZ-83 drilled in 2004 intersected 4.94 grams gold per tonne (g Au/t) over a true width of 12.6m in the Main Reef in this area.

Underground services are being installed to enable underground drilling in the Morro do Vento Extension to test the possibility that the Main Reef, intersected in Hole MCZ-83, may extend to shallower levels near the old mine workings.

At Canavieiras, underground services are being installed and an 80 metre long crosscut is being driven to enable underground drilling to test the southeastern and southern extensions of the Piritoso/Liberino Reefs that were previously mined and the MU/LU Reefs below the old workings. The mine is also being completely re-surveyed.

In the Northern area, one track-mounted diamond drill, shortly to be joined by a second surface drill rig, is following up on excellent intersections at Pindobacu 50 km north of Jacobina including 5.46 g Au/t over a true width of 21.9m in Hole PB-2.

Fugro-LASA-Geomag has been contracted to complete a 50 line-kilometre induced polarization geophysical survey in the Pindobaqu-Fumaga , area. A detailed soil geochemical survey and detailed geological mapping is also in progress to cover the entire 15 km strike length of the target zone.

Dr. Paul Karpeta, an expert on Precambrian conglomerate-hosted gold deposits with extensive experience in the Witwatersrand, South Africa and at Tarkwa, Ghana, has been contracted to complete a study of the Jacobina basin to identify additional entry points outside the mine area where conglomerates would have been deposited.

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 program. Peter Tagliamonti, P.Eng. is the Qualified Person, as defined under National Instrument 43-101, responsible for all engineering and mining reserve estimates and has been on-site throughout the mine re-development since April 2004.

Desert Sun Mining is a Canadian gold exploration and development 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. The mine is scheduled to re-start operations in April of 2005 with proven and probable mineral reserves of 10,746,000 tonnes at 2.2g Au/t containing 758,000 ounces of gold. As a result of the Desert Sun’s exploration programs to date, Measured and Indicated resources total 24,800,000 tonnes @ 2.53 g Au/t containing 2,050,000 ounces of gold, and Inferred Resources total 22,000,000 tonnes @ 2.61 g Au/t containing 1,900,000 ounces of gold. The mineral reserves are included within the Measured and Indicated mineral resources. For additional information, please see Desert Sun’s website at www.desertsunmining.com.

DESERT SUN INCREASES JACOBINA GOLD MINE
RESERVES TO NEARLY 1 MILLION OUNCES

DESERT SUN MINING CORP. (TSX:DSM, AMEX:DEZ) has completed a mineral reserve estimate for its Jacobina Mine – Joao Belo Zone – based on the latest Measured and Indicated mineral resource estimates released on December 15, 2004. Mineral reserves in the Joao Belo zone as estimated in the SNC Feasibility study of September 2003 were 7,471,000 tonnes at 2.10 g Au/t containing 504,000 ounces of gold.

Proven and probable mineral reserves in the Joao Belo zone are now 11,102,000 tonnes grading 2.04 g Au/t containing 727,000 ounces, an increase of 44% in contained ounces. Total Proven and Probable mineral reserves in all zones at Jacobina, which previously were 10,746,000 tonnes at 2.20 g Au/t containing 758,000 ounces of gold, are now 14,378,000 tonnes at 2.12 g Au/t containing 980,000 ounces of gold as summarized in Table 1 below. The conversion rate of the new indicated resource to mineral reserve is about 75% which is comparable to the historical experience at the mine and to the conversion rate of the SNC Lavalin feasibility study.

This new reserve is now being used in the Jacobina Mine development plan and increases mine life by over two years. The other major zones – Morro do Vento, Morro do Vento Extension (Basal/Main Reef), Canavieiras and Serra do C6rrego – will have updated and/or new mineral reserves estimated as mine planning/feasibility studies for each area are completed. The total Measured and Indicated mineral resource at Jacobina for all zones is 24,800,000 tonnes grading 2.53 g Au/t containing 2,050,000 ounces of gold (see press release December 15, 2004).

“The 44% increase to 727,000 ounces from the original estimate of 504,000 ounces in Proven and Probable reserves for the Jacobina Mine – Joao Belo Zone – allows us to extend the mine life of our primary ore zone,” commented Peter Tagliamonte, Vice President, Operations and Chief Operating Officer. “Our expectations are that, as the Mine Project Team works through the other zones included in the Measured and Indicated resources, we will see further significant increases in reserves.”

The Measured and Indicated resource estimate upon which these new reserve estimates are based was reviewed and confirmed by Terry Hennessey, P.Geo. of Micon International. Mr. Hennessey, who is an independent qualified person as defined under National Instrument 43-101 as reported in the press release dated December 15, 2004. The resource estimation methodology and classification used is the same as outlined in the August 2003 report by Mr. Hennessey filed on SEDAR. The mineral reserve estimate was completed by the Desert Sun Mining group at Jacobina under the direction of Mr. Tagliamonte, P.Eng. who is a Qualified Person, as defined by National Instrument 43-101.

Key parameters for the mineral reserve estimate as set out in Table 1 below are as follows:

Mineral resources and reserves were estimated using the polygonal method on vertical longitudinal sections

Dilution is 1 metre on the hanging wall and 1 metre on the footwall at grades indicated by diamond drilling

Mining recovery rate is 80%

High assay cutting factor is 30 grams gold per tonne

Specific gravity is 2.6 based on tests completed for the SNC Lavalin feasibility study

Block cut-off grade is 1.33 grams gold per tonne

Gold price is US$350 per ounce

Desert Sun has all operating permits in place for production

Assaying for the drilling program, which defined the new Indicated mineral resources, 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 Personas defined under National Instrument 43-101 responsible for the scientific and technical work on the exploration program.
