EXPLORATION UPDATE
Limon Mine Area
Drilling has continued on the new Santa Pancha southern extension to follow up on the promising results from the initial discouvery drilling previously reported and as shown on vertical longitudinal section below in Figure 1. Central Sun Mining Inc. has completed 14 diamond drill holes totaling 4,441 metres of a planned 10,000 metre program in the Limon Mine area. The Santa Pancha orebody, which has the highest grade within 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.
"We are very excited about the high grades and significant widths being discovered by Dr. Pearson and his exploration team" commented Peter Tagliamonte, President and CEO, "it really shows the potential of the area and with the ongoing exploration program we are confident in our ability to define this new discovery and to grow it into a considerably larger production base for the Limon Mine."
Commencing with Hole LM-08-10 the drill program has focused on defining a mineral resource in the new extension area with drill hole spacing at approximately 50 metres by 50 metres. Complete drilling results are listed below in Table 1 and shown in Figure 1.
Significant results from the first definition holes are as follows:
- 8.76 g Au/t (6.21 cut) over true width of 15.4 metres in LM-08-13
- 6.70 g Au/t over true width of 6.6 metres in LM-08-14
- 6.25g Au/t over true width of 5.0 metres in LM-08-10
- 7.43 g Au/t over true width of 3.8 metres in LM-08-12
Holes LM-08-008 and LM-08-009 were part of a deeper series of holes approximately 100 metres below the first six holes. A 34 metre wide (true width) altered and mineralized zone was intersected in LM-08-009 which returned 3.83 g Au/t over a true width of 2.0 metres.
Dr. Bill Pearson, P.Geo., Executive Vice President, Exploration commented, "Drilling is contining to confirm the potential for a significant mineral resource in this zone. The closer spaced drilling is providing better definition of the distribution of gold mineralization within this extensive structure. Downhole induced polarization surveys will also be carried out to aid in outlining the full extent of the strong zones of silicification with which the best grade mineralization is associated."
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 in 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 metres.
Orosi Mine Area
Exploration drilling totaling a minimum of 10,000 metres is planned for the Orosi Mine area of which 7,140 metres in 40 holes have been completed to date including the check holes previously reported that were recommended by Scott Wilson (758 metres in 5 holes). Targets being tested as shown below in Figure 2 include Mojon SW, Victoria-Santa Maria, San Juan, Los Angeles and Quernos do Oro. In addition, an induced polarization geophysical survey has been completed covering a potential strike extension of 3 kilometres of the Mojon-Crimea and associated structures northeast of the mine.
Drilling of 2,036 metres in 12 holes has been completed to test the San Juan vein structure, a potential open pittable target, located about 5 kilometres south of the mine area. These holes tested the structure over approximately an 800 metre strike length to a vertical depth of 180 metres. All but one hole intersected gold mineralized quartz veins/vein breccias. Significant results previously reported from the first six (6) holes (see press release April 30, 2008) include 19.55g Au/t (17.58 cut) over 1.2 metres true width and 2.48 g Au/t over 5.7 metres true width. Significant results from the new holes include 18.28 g Au/t (13.26 cut) over 1.9 metres true width in SJ-08-07 and 2.86 g Au/t over 7.6 metres true width in SJ-08-08. Table 2 gives complete results. Compilation of new drill data with historical drill data is being completed to outline the best areas for resource definition.
A detailed mapping program including re-interpretation of previous geological data in conjunction with new diamond drilling and petrological work by Dr. Robert Hodder, P.Geo., a well known specialist in epithermal gold systems, working with the Central Sun exploration team has outlined a number of new targets along the Mojon-Crimea structure which hosts the majority of the mineral resources outlined to date at Orosi. A particular focus has been the potential extension to the southwest of the current pit design limits on Mojon. Seven (7) holes totaling 1,548 metres have completed to test potential new structures. Results on these holes are pending.
Trenching on the Cuernos de Oro structure located 2 kilometres north of the mine has been completed with results pending. Drilling to test this structure over a strike length of 1 kilometre has now commenced.
In the Victoria-Santa Maria area, twelve (12) holes totaling 2,618 metres have been completed at approximately 100 metre spacing to test the structure between the two mining areas that previously had very little drilling. All holes have intersected mineralized structures. Results have been received for the first five (5) holes only but no significant values were returned.
Induced Polarization/Resistivity surveys totaling 38.6 line kilometres in 21 lines have been completed to explore the potential strike extension over approximately 3 kilometres of the Mojon-Crimea structures as well as satellite structures to the immediate northeast of the mine area. This survey has outlined a number significant anomalies including two major chargeability anomalies 1.2 kilometres and 2.5 kilometres northeast of the mine area respectively, as shown below in Figure 2. The chargeability response likely results from sulphide mineralization in an alteration envelope. These anomalies are highly prospective for gold. Significantly, the chargeability is stronger at depth than at the surface which explains why this area has received little previous attention and there is a lack of small miner activity. Dr. Chris Hale, P.Geo. consulting geophysicist who supervised the work and is a Qualified Person as defined by National Instrument 43-101 has recommended an initial program of 8 drill holes to test these anomalies. The targets have been ground checked and the hole locations confirmed. Drilling commenced at the end of June.
Dr. Bill Pearson, P.Geo. commented "The program at Orosi has accelerated significantly over the past two months with our improved understanding of the geology and distribution of gold mineralization. It is evident that the Mojon-Crimea structure extends much further to the northeast and the results of the IP survey have outlined strong anomalies on this structure as well as satellite ones with excellent potential to host significant gold mineralization. In addition, we have obtained a number of positive drilling results but also have a large backlog of some 1,500 samples pending. The completion of the new office and core logging facilities has greatly improved the efficiency of our exploration team."
Mestiza-La India Area
At Mestiza-La India, located 70 kilometres east of Limon, as previously reported, 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 that a complete epithermal system is exposed from the lower intrusive at La India 10 kilometres to the southeast to an area of high level quartz veining 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 Technical Report dated March 31, 2008 posted on SEDAR). This vein has now been traced for a strike length of 5 kilometres.
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 of over 800 metres is associated with the Guapinol vein in the middle of the Mestiza property. This anomaly persists to the maximum depth as 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 metre drill program to evaluate these anomalies beginning in August 2008. Geological mapping, sampling and prospecting is continuing with trenching of selected areas also planned.
SAMPLING, ASSAYING AND QUALITY CONTROL
The core (NQ 47.6 mm) was 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.
The Limon Mine laboratory uses 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.

Cautionary Note to U.S. Investors Concerning Estimates of Measured, Indicated or Inferred Resources
The information presented uses the terms "measured", "indicated" and "inferred" mineral resources. United States investors are advised that while such terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize these terms. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and as to their 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 other economic studies. United States investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. United States investors are also cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically or legally mineable.
