Andover Mining Corp. Adds Strike Length to S.W. SUN Deposit, SUN District, Ambler Mineral Belt

VANCOUVER, 10/15/12 - Andover Mining Corp. (TSX VENTURE: AOX )(OTCBB: AOVTF) (FRANKFURT: R2X) ("Andover" or the "Company") is pleased to announce that the last of the drill assays have been received from the 2012 drilling campaign at the SUN project, Ambler Mineral Belt, Alaska.

Assays have been received from drill hole SUN 12-44, which was completed on September 05, 2012. Drill hole SUN 12-44 is approximately 100 meter southwest of all previous drilling at the S.W. SUN Deposit. Results are summarized in the following table:

Previous results from S.W. SUN drilling were reported in news releases dated September 05, 2012, Aug 22, 2012 and July 18, 2012.

The 2012 drill program is now completed and all the drills, equipment and staff have been successfully demobilized from the site.

"SUN 12-44 is an exciting hole in the development of the S.W. SUN Deposit," said Kent Turner, Andover's Chief Operating Officer. "It not only serves to demonstrate both an additional 100 meters of strike length to the deposit with open down-dip potential, but importantly the copper grade is significantly higher than that seen in SUN 12-30 and SUN 12-34, the 2 next closest holes to the northeast. Perhaps more importantly still, the S.W. SUN Deposit remains wide open on strike to the southwest and down dip. As the outcrops have disappeared beneath talus and scree cover in this direction, the additional strike potential towards the southwest remains undefined. With this new additional strike length and still open on strike at S.W. SUN, the new discoveries at STU and SAL and our success at defining new mineralization at Main SUN, the drill-demonstrated mineralization in the SUN District continues to impress."

The 2012 drill core was logged, split and boxed on site by Andover's geologists. The core was shipped to the ALS-Chemex Prep Lab in Fairbanks, Alaska. The pulps from Fairbanks were analyzed for 35 elements at the ALS-Chemex facilities in Vancouver, British Columbia and the gold assays were performed at ALS-Chemex facilities in Reno, Nevada. Base metal over-limits were wet assayed. Blanks and standards were inserted with each sample shipment.
