Andover Mining Corp. Increases Strike Length to the Northeast of SUN Deposit, Ambler Mineral Belt

VANCOUVER, 10/11/12 - Andover Mining Corp. ("Andover" or the "Company") (TSX VENTURE: AOX) (OTCBB: AOVTF) (FRANKFURT: R2X) is pleased to report additional assay results from the 2012 drilling campaign at the SUN District, Ambler Mineral Belt, Alaska. Results from drill holes SUN 12-42 and SUN 12-43 increased the drilled strike length at the Northeast end of the Main SUN Deposit.

Assays have been received from drill holes SUN 12-42 and SUN 12-43, targeting the Main SUN Deposit. Together with the previously released assay results from drill hole SUN 12-41, these drill holes have extended the drilled resource a full 300 meters down dip and increased the strike length on the Northeast end of the Main SUN Deposit some 50 meters. Results are summarized in the following table:

Previous results from Main SUN drilling were reported in news releases dated July 18, August 21, August 29, September 12, September 19, and September 26, 2012.

Drilling has been completed at the SUN Project for the 2012 field season. The drills have been demobilized from the camp. Assay results continue to become available from the labs, and will be reported as received and verified.

"The results from the two holes (SUN-12-41 & 42) on the Northeastern end of the Main SUN deposit collectively extend the drilled resource a full 300 meters down dip for about 50 meters further northeast than previously drilled," says Kent Turner, Andover's COO. "They also serve to better define the geometry of the Main SUN zone in this area. Holes previously thought to close off or restrict mineralization in this direction may not have adequately tested the system, although only additional drilling will be able to confirm this possibility. SUN-12-43 confirmed mineralization in an up-dip, near surface area above previously drilled mineralization and demonstrates the possibility that at least some of the SUN deposit may be amenable to open pit development."

The 2012 drill core was logged, split and boxed on site by Andover's geologists. 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.

This news release has been reviewed by Bradley C. Peek, Certified Professional Geologist (AIPG CPG-11299) and General Manager for Andover's Ambler District projects. Mr. Peek is a National Instrument 43-101 qualified person and is responsible for the technical aspects of this news release.
