Central Sun Extends New Zone at Limon-Intersects 4.54 Grams Gold Per Tonne Over 15.4 Metres True Width

TORONTO, ONTARIO--(Marketwire - Feb. 20, 2008) - Central Sun Mining Inc. (TSX:CSM)(TSX:CSM.WT)(AMEX:SMC) -


Central Sun Mining Inc. (the "Company") has scheduled a conference call for analysts and investors on Thursday, February 21, 2008 at 11:00 a.m. (Eastern) to provide an update on its exploration and operations activities.

Conference Call

To participate in the conference call, please dial 416-641-6132 or 1-866-226-1792 about five minutes prior to the start of the call.


Limon Mine Area

Central Sun Mining Inc. has completed the first three diamond drill holes of a planned 10,000 metre program in the Limon Mine area. Results of the first two holes were previously reported in a press release dated January 29, 2008. The first three holes have 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.

Hole LM-08-003 intersected 4.54 g Au/t over a true width of 15.0 metres within a strong alteration zone 40 metres wide. Hole LM-08-003 extends the potential strike length of the new zone by over 200 metres. LM-08-003 is located approximately 200 metres south of Hole LM-08-001 which intersected 5.83 g Au/t (4.99 cut) over a 12.3 metre true width including 9.62 g Au/t (8.03 cut) over a 6.5 metre true width as previously reported.

As show in Figure 1, historical drilling further to the south of LM-08-003 intersected significant values of 28.93 g Au/t over 2.3 metres true width, 7.94 g Au/t over 8.85 metres true width and 4.57 g Au/t over 4.41 metres true width.

Dr. Bill Pearson, P.Geo., Executive Vice President, Exploration commented, "This is an excellent result as the hole confirms significant gold mineralization in the area where very little exploration has been previously carried out. The good results from historical drill holes further to the south as shown on the longitudinal section indicate that the potential for further extending this new zone is excellent and significant. The next three holes will test this area and then a deeper cut of holes will be completed. This is a major structure that continues to be open both along strike to the south and down dip."

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 vertical extent of the target zone is between 100 to 150 metres; however, the full potential extent of the epithermal vein system at depth has not been tested and remains open.

Orosi Mine Area

Exploration drilling at the Orosi Mine area has now started. A second drill rig has commenced drilling in the Orosi Mine area with a planned 10,000 metre program. An initial six holes totalling about 700 metres are being completed on the Santa Maria and Mojon structures as recommended by Scott Wilson Roscoe Postle Associates Inc. Compilation and interpretation of the historical drilling information has outlined a number of additional targets in the general mine area. A total of 3,000 metres of drilling are planned to test these targets. Line cutting is in progress on the potential northeastern extensions of the vein structures with induced polarization (IP) surveys to be carried out. Geological mapping, sampling and prospecting as well as data compilation for this area are in progress.

Mestiza Area

Exploration activity at Mestiza has also begun. IP surveys have commenced at the Mestiza property, located 70 kilometres east of Limon, along with geological mapping, sampling, prospecting and data compilation. Preliminary 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.


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 also be analyzed at the Limon Mine laboratory until the second circuit currently being installed at the Orosi laboratory is completed.

The Limon 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.
