Andover Reports Assay Results From the 2012 Drill Program at SUN Property, Ambler Mineral Belt, Alaska

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 21, 2012) - Andover Mining Corp. ("Andover" or the "Company") (TSX VENTURE:AOX)(OTCBB:AOVTF)(FRANKFURT:R2X) is pleased to announce assay results from its 2012 drilling program on the Main SUN Deposit on the Company's SUN District project located in the Ambler Mineral Belt, Northwest Alaska.

Drill core from the 2012 program was logged, split and boxed on site by Andover's geologists. Core from SUN 12-31 and SUN 12-33 were 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.

Drill hole SUN 12-31 was completed at a depth of approximately 316 meters and drill hole SUN 12-33 was completed at a depth of approximately 154 meters. Both these drill holes tested the Main SUN Deposit (see news release dated August 8/ 2012 and July 18/ 2012 for previously released 2012 drill results). Significant drill intercepts from SUN 12-31 and SUN 12-33 are reported in the following table.

"The drilling on the Main SUN Deposit continues to define and increase the known size of the deposit," states Kent Turner, Andover's COO. "We have retained Mine Development Associates of Reno, Nevada to complete a National Instrument 43-101 compliant resource calculation and a preliminary economic assessment for the SUN Deposit after the 2012 drill campaign is completed."

Drilling continues on both the SUN Deposit and S.W. SUN Deposit. Further assays will be released as they are received. Drilling is being conducted on a 24 hour basis, 7 days a week, and is expected to continue into September 2012.
