Core International Limited Reports Assay Results From Optioned Dog Lake Claims

TORONTO--(Marketwire - November 21, 2007) - Core International Limited (PINKSHEETS: CRLD) reports assay results from optioned Dog Lake claims.

Core International Limited announces the assay results from the six (6) soil samples submitted for till sample processing and kimberlite indicator mineral selection, collected from their optioned Dog Lake mining claims.

Each sample was wet screened at 20 and 60 mesh. All of the +20 mesh and -60 mesh material was dried and stored. The -20+60 mesh fraction was submitted for heavy liquid separation (Methylene iodide @ 3.1 g/cc). Following heavy liquid separation, the Sink material was cleaned in an ultrasonic bath. The sample was dried, weighed and submitted for dry screening (35 mesh) and magnetic separation (hand-magnet and Frantz electromagnetic separator). The mineral concentrates were observed with a binocular microscope for the selection of kimberlite indicator mineral species.

The assay results returned mostly insignificant values for most of the kimberlite indicator minerals tested for, but did give values for Ilmenite and Chromite as the recorded minerals present. Further information about the potential kimberlite diamond prospectivity may be gained by analyzing the selected kimberlite indicator minerals by electron microprobe.

The Company is now waiting for completion of the field report from MMES Inc., on the specific ground geophysics, ground magnetometer surveying testing the potential of the anomalies previously identified by the airborne survey of 2006, to host gold mineralization.

"The real body of work, on a preliminary basis, will be in the findings and recommendations of the pending field report. We should get a more specific direction towards, and a better understanding of the potential of the selected anomalies, to host gold mineralization, and the best way to proceed from here," said company president Jan Vrba.

"We have also been active in our negotiations with several other prospective gold mining properties here in Canada and the US, and should have something to announce very shortly."
