EXPLORATION UPDATE

Limon Mine Area

Central Sun Mining Inc. has completed seven (7) diamond drill holes totaling 2,291 m of a planned 10,000 metre program in the Limon Mine area. Results of the first three holes were previously reported in press releases dated January 29, 2008 and February 20, 2008, respectively. The first three holes successfully intersected a major new zone that significantly extends the potential downdip and on strike extensions of the Santa Pancha orebody as shown on the vertical longitudinal section (Figure 1). The Santa Pancha orebody, which has the highest grade of the Limon Mine area deposits, is currently being mined on the 100 metre level at a reserve grade of approximately 5.6 g Au/t.

Holes LM-08-004 to LM-08-006 tested the potential extension of this new zone from 120m to 250m further south of Hole LM-08-003 which intersected 4.54 g Au/t over 15.0m true width. All three holes intersected wide zones of alteration principally silicification and carbonatization that ranged from 25m to 40m in true width. Hole LM-08-004 intersected two mineralized zones grading 7.22 g Au/t over 3.4m true width and 2.57 g Au/t over 2.6m true width. Lower grade values were returned from Hole LM-08-05 (2.78 g Au/t over 2.7m true width) and in LM-08-006, in which carbonate alteration was predominant, no significant values were returned.

A deeper series of holes approximately 100m below the first six holes was commenced with Hole LM-08-007. This hole intersected a 12m wide (true width) zone of quartz veining and quartz vein breccia but returned only low grade values. Hole LM-08-008 intersected a 12m wide (true width) mineralized zone; assays on this hole are pending. Complete drilling results are listed in Table 1.

Dr. Bill Pearson, P.Geo., Executive Vice President, Exploration commented, "Drilling continues to confirm that the Santa Pancha structure is very extensive and remains open at depth. However, closer spaced drilling is required to fully assess the resource potential of this zone. One additional deep hole further south will be completed and then the drill spacing will be tightened to approximately 50m centres to better define the distribution of gold mineralization within this extensive structure."

The Santa Pancha structure, located about 4 kilometres east of the Limon processing plant, strikes N20E and extends for approximately 2.5 kilometres along strike. The target zone being tested as shown on the longitudinal section (Figure 1) extends for approximately 650 metres along strike from the No. 2 shaft area southwards to the No. 8 shaft. The drill holes completed to date have confirmed that the favourable structure extends to a vertical depth of at least 350 m.

Orosi Mine Area

Exploration drilling totaling 10,000m is planned for the Orosi Mine area. An initial five holes totalling 762 metres were completed on the Santa Maria, Mojon and Santa Elena structures in the mine area as recommended by Scott Wilson Roscoe Postle Associates Inc. Results of these drill holes which confirmed previous reverse circulation drilling are listed in Table 2. These results are being incorporated into the updated mineral resource estimate being completed by Scott Wilson as part of the Orosi Mill feasibility study.

Drilling of 1,903 m in 10 holes has been completed to test the San Juan vein structure, a potential open pittable target, located about 5km south of the mine area. These holes tested the structure over approximately an 800m strike length to a vertical depth of 180m. All but one hole intersected gold mineralized quartz veins/vein breccias. Significant results from the first seven (7) holes for which assay results have been received include 19.55g Au/t (17.58 cut) over 1.2m true width and 2.48 g Au/t over 5.7m true width. Table 2 gives complete results.

Recent geological and petrological work by Dr. Robert Hodder, P.Geo., a well known specialist in epithermal gold systems, has better characterized the nature and distribution of alteration related to the gold mineralization at Orosi. Diatreme-type breccias appear to be an important control on the distribution of mineralization with vuggy silica and quartz-adularia veins being important indicators for areas of gold mineralization. Dr. Hodder concludes that none of the deposits studied thus far appear to have bottomed-out in a geological sense. Further he notes the importance of post-mineral faults in displacing mineralized zones opening up possibilities for additional target areas especially in topographic lows resulting from down dropped blocks. A detailed geological mapping program is currently in progress in the general mine area to apply this new geological information and identify additional target areas for drilling.

Induced Polarization/Resistivity surveys have begun at Orosi to target mineralization in the potential northeastern extention of the Mojon-Crimea and Santa Maria structures.

Mestiza-La India Area

At Mestiza-La India, located 70 kilometres east of Limon, Magnetic, Resistivity and Induced Polarization (IP) surveys have been conducted on approximately 45 line kilometres of new exploration grid oriented perpendicular to the Tatiana vein crossing the Mestiza property, along with geological mapping, sampling, prospecting and data compilation. Preliminary geological mapping indicates it is likely that a complete epithermal system is exposed from the lower intrusive at La India 10 kilometres to the southeast to high level quartz veins at Mestiza. Vertically, the system appears to extend from about 500 metres to perhaps as much as 900 metres. Historic production from 1938 to 1955 at La India was 575,000 ounces of gold from 1.73 million tonnes grading 13.4 g Au/t. The Tatiana vein on the Mestiza property contains an inferred mineral resource of 558,000 tonnes at 8.80 g Au/t containing 158,600 ounces of gold (see Annual Information Form dated March 31, 2008 posted on SEDAR).

Significantly higher resistivity anomalies are associated with all of the major veins that are known on the property including the Tatiana, Espinito, Guapinol, and Constancia-America showings. These anomalies persist to the maximum search depth of the dipole array (n equals 8, a equals 25m). Resistivity and IP data show that the anomaly associated with the Espinito vein strengthens with depth where it is paired with a second resistive structure. A much stronger resistivity high with a strike length over 800 m is associated with the Guapinol vein in the middle of the Mestiza property. This anomaly persists to the maximum depth sampled in both the resistivity and chargeability data. It provides a high priority drill target.

A north-south trending resistive structure is located in the previously unexplored southwest part of the grid. This trend is potentially the northward strike extension of the La India vein onto the Mestiza property.

Eight (8) targets have been outlined for drilling including the Guapinol, Espinito, Norte de La India, and Tatiana anomalies. Planning is underway for a 2,500 m drill program to evaluate these anomalies beginning in June 2008.

Dr. Christopher J. Hale, P. Geo. the qualified person for the geophysical programs commented, "I am very pleased with the high quality work that CSM's team has been doing at Mestiza. Central Sun enjoys the flexibility offered by an in-house Nicaraguan technical team provided with the latest in instrumentation. Resistivity in particular has been shown to be an excellent technique to target the silicious vein systems on the property and at depths approaching a hundred metres. CSM has been quick to recognize that modern geophysical surveys can target drilling to evaluate discoveries systematically and efficiently."

SAMPLING, ASSAYING AND QUALITY CONTROL

The core (NQ 47.6 mm) is logged, photographed and then sawn in half with one-half sent to the laboratory for analysis and the other half retained and stored on site. All core samples were prepared and assayed at the Company's Limon Mine laboratories. The Limon mine laboratory has a separate preparation circuit for exploration samples so that these are prepared and analyzed separately from run-of-mine samples. Samples for the Orosi drill program will be analyzed at the Orosi Mine laboratory. A second circuit is currently being installed at the Orosi laboratory; however, no run-of-mine samples are currently being assayed at this facility.

Both the Limon and Orosi Mine laboratories use normal industry procedures. The entire half-core samples are crushed to pass 10-mesh-size sieve, a 1/4 split is then pulverized to have greater than 90% passing the 200-mesh-sized sieve to produce a 100 gram homogenized sub-sample. A one-assay ton aliquot (a 29.2 gram sub-sample) is used for fire assaying with an atomic absorption (AA) or gravimetric finish to determine gold concentration. Internal quality control includes the use of blanks, duplicates and standards in every batch of samples. The Company also conducts internal check assaying. Regular external check assays are performed at a certified Canadian commercial laboratory and certified external reference standards are inserted into each batch.
