Summary of Material Change

 

Central Sun Mining Inc. (“Central Sun” or the “Company”) announced updated mineral reserve and mineral resource estimates for its Limon Mine, Orosi Mine and Mestiza-La India projects in Nicaragua. These updated estimates include the results of the successful 2008 exploration program which discovered new zones at Limon (Santa Pancha South) and Orosi (San Juan).

Full Description of Material Change

 

Central Sun announced updated mineral reserve and mineral resource estimates for its Limon Mine, Orosi Mine and Mestiza-La India projects in Nicaragua. These updated estimates include the results of the successful 2008 exploration program which discovered new zones at Limon (Santa Pancha South) and Orosi (San Juan). The recently returned Cerra Quema property in Panama and the Bellavista Mine are currently being evaluated and are not included in this current estimate.

Total proven and probable mineral reserves at Limon Mine are estimated at 1,158,000 tonnes at 4.68 g Au/t containing 174,100 ounces of gold. This reduction of 43,100 ounces from the December 31, 2007 estimate of 1,381,000 tonnes at 4.89 g Au/t containing 217,200 ounces is due principally to losses from mining and reclassification of certain blocks in the Talavera mine as the mining activities shift to the Santa Pancha area. Total measured and indicated mineral resources excluding reserves are estimated at 563,400 tonnes at 5.68 g Au/t containing 102,900 ounces of gold as compared to 384,000 tonnes at 4.99 g Au/t containing 61,600 ounces of gold in December 31, 2007. This increase reflects reclassification of some reserve blocks in the Talavera mine not currently accessible to measured and indicated resources as well as some additions from exploration in the Santa Pancha Mine. As a result of the successful 2008 exploration that discovered the new Santa Pancha South zone, inferred mineral resources in the Limon Mine are now estimated at 2,441,000 tonnes at 5.34 g Au/t containing 419,300 ounces a significant increase of 173,300 ounces from the December 31, 2007 estimate of 1,291,000 tonnes grading 5.91 g Au/t containing 246,000 ounces gold. The bulk of this increase is in the new Santa Pancha South zone which is estimated to contain 1,033,000 tonnes grading 4.99 g Au/t containing 165,600 ounces of gold.

Total proven and probable mineral reserves at the Orosi Mine mainly in the Mojon-Crimea zone are unchanged from the January 31, 2008 estimate by Scott Wilson Roscoe Postle Associates (“Scott Wilson RPA”) of 11,017,000 tonnes at 1.44 g Au/t containing 509,500 ounces of gold as previously reported (see

press release May 8, 2008). Similarly, measured and indicated mineral resources excluding reserves as estimated by Scott Wilson RPA are unchanged at 4,126,000 tonnes at 1.51 g Au/t containing 200,400 ounces of gold. The NI 43-101 report by Scott Wilson RPA is available on SEDAR. Inferred mineral resources in the new San Juan zone located 5 kilometres south of the plant are estimated to be 2,221,000 tonnes at 1.98 g Au/t containing 141,400 ounces of gold. This includes a higher grade portion mainly in the northeast end of the zone containing 395,000 tonnes at 4.79 g Au/t containing 61,000 ounces of gold. The structure, which has been drilled over a strike length of one kilometre, is open along strike in both directions and at depth. In addition, excellent drill results including 13.04 g Au/t (12.31 g Au/t with highs cut to 25 g Au/t) over a true width of 5.0 metres at a vertical depth of only 30 metres and 2.61 g Au/t over a true width of 4.5 metres at a vertical depth of about 20 metres were obtained at the Los Angeles target which is a possible satellite target adjacent to San Juan. Overall inferred resources of 224,000 ounces of gold for Orosi include an additional 3,370,000 tonnes at 0.76 g Au/t containing 82,600 ounces of gold in spent ore as estimated by Scott Wilson RPA.

At Mestiza-La India, no drilling was completed in 2008. Geological mapping indicates that 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 576,000 ounces of gold recovered from 1.7 million tons grading 0.39 ounces per tonne (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 as previously reported.

Qualified Persons

The mineral reserve and mineral resources estimates for the Limon mine, excluding the Santa Pancha South zone, were prepared using conventional polygonal methods by CSM mine personnel under the supervision of Dr. William (Bill) Pearson, P.Geo. and Mr. Graham Speirs, P.Eng., both of whom are qualified persons as defined under National Instrument 43-101. The mineral resource estimate for the Santa Pancha South zone was prepared using a block model and ordinary kriging by CSM exploration personnel in Managua and Mr. Farshid Ghazanfari, an experienced GEMCOM resource specialist based in Toronto under the supervision of Dr. Pearson. An updated NI 43-101 technical report outlining the updated estimates for Limon and Orosi will be filed on SEDAR within 10 days of this release.

The mineral reserve and mineral resources estimates for the Orosi mine, excluding the San Juan zone, were prepared using block models by Scott Wilson RPA as outlined in their NI 43-101 technical report dated June 26, 2008 filed on Sedar. The mineral resource estimate for the San Juan zone was prepared using a block model and ordinary kriging by CSM exploration personnel in Managua and Mr. Farshid Ghazanfari, an experienced GEMCOM resource specialist based in Toronto under the supervision of Dr. Pearson. An updated NI 43-101 technical report outlining the updated estimates for Orosi has been filed on SEDAR.

Sampling, Assaying And Quality Control

The core (NQ - 47.6 mm diameter) for the 2008 drilling program for both Limon and Orosi was logged, photographed and then sawn lengthwise 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. This laboratory has a dedicated preparation circuit for exploration samples so that they are prepared and analyzed separately from run-of-mine samples.

The Limon Mine laboratory uses normal industry procedures for sample preparation and fire assaying. 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) of this homogenize 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.
