KEEGAN CONTINUES TO RECEIVE EXCELLENT RESULTS FROM DRILLING SOUTH OF ESAASE GOLD RESOURCE
Vancouver, BC, September 18, 2008 - Keegan Resources Inc.

("Keegan") is pleased to announce additional results from step out drilling up to 900 meters south of the boundary of the existing 43-101 resource at the Esaase property.

Highlights include 23 m @ 4.2 g/t Au, 26 m @ 2.51 g/t Au, and 26 m @ 1.49 g/t Au.

Keegan is continuing to test mineralization in the south extension of the A-1 zone both down and up dip of previous drilling.

The drill holes in this area continue to consistently intersect significant grade-widths in the moderately west dipping basal zone of mineralization, and to date, all intercepts have been encountered at a relatively shallow depths, Please see www.keeganresources.com for a drill hole location map. Table 1: Intercepts from south step out drilling at the Esaase property having a minimum grade-width of approximately 15 g/t Au x meter.

Intercepts with grade-widths of approximately 40 g/t Au x meter or higher are bolded. Distances are in drilled meters and grades reported in g/t Au.

President and CEO Dan McCoy states: "We are continuing to make significant additions to the Esaase deposit at relatively shallow depths which is key to the successful development of an efficient, modern open pit gold mine. Regionally, these results also complement the results of recent surface exploration from the adjacent Jeni mining lease and continue to illustrate the excellent and evolving potential for the district to become a significant Ghanaian gold producer.

We expect to continue to rapidly advance exploration and engineering efforts at Esaase during the coming months." Richard Haslinger, P.

is the Qualified Person with respect to NI 43-101 at Esaase.

RC samples were taken at one meter intervals under dry drilling conditions by geologic and resource consultant RSG Global, Inc.

utilizing drilling and sampling techniques widely accepted in resource definition studies of other West African gold deposits.

All reverse circulation drill samples are weighed on site.

Drill core is HQ diameter and is split logged and sampled on site.

All core and RC samples are assayed using standard 50 gram fire assay with atomic absorption finish by Transworld Laboratories (GH) Ltd.

in Tarkwa, Ghana, SGS Labs in Tarkwa, Ghana, or ALS Chemex Labs in Kumasi, Ghana.

QA/QC programs using internal and external standard samples, re-assays, and blanks indicate good accuracy and precision in a large majority of standards assayed.

Repeatability in duplicate samples is generally within 10% variance.

In instances where variance is greater than 10%, the assays from both samples are averaged.

Intercepts were calculated to emphasize width rather than grade: a minimum of a 0.2 g/t cut off at beginning and end of the intercept and allowing for no more than six consecutive samples (six meters) of less than 0.2 g/t Au.

All internal intercepts above 10 g/t Au are reported within the intercept.

Intercepts of less than 15 g/t Au x meter grade-thickness are not routinely reported. Mineralization in the A structure strikes approximately 10 to 30 degrees east of north and dips 45 to 90 degrees to the west.

Holes are drilled at 110 degrees azimuth and are inclined at 45 to 60 degrees, so true widths are estimated to be over 80% of the drilled widths.
