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

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 08/22/12 -- Andover Mining Corp. ("Andover" or the "Company") (TSX VENTURE: AOX)(OTCBB: AOVTF)(FRANKFURT: R2X) is pleased to announce updated results from its on-going drilling campaign at the S.W. SUN Deposit on the Company's SUN District project, located in the Ambler Mineral Belt, Northwest Alaska.

Assays have been received from drill holes SUN 12-30, SUN 12-32, SUN 12-34 and SUN 12-37 that targeted the S.W. SUN Deposit. These drill holes stepped out to the southwest and down dip from previous drilling. Drill hole SUN 12-30 was completed at a depth of approximately 136 meters, drill hole SUN 12-32 was completed at a depth of approximately 480 meters, drill hole SUN 12-34 was completed at a depth of approximately 379 meters and SUN 12-37 was completed at a depth of approximately 328 meters. Significant drill intercepts from SUN 12-30 and SUN 12-34 are reported in the following table. (see news releases dated August 21/ 2012, August 08/ 2012 and July 18/ 2012 for previously released 2012 results.)

         Note(i) SUN 12-32, SUN 12-37 had no significant intercepts.

The 2012 drill core was logged, split and boxed on site by Andover's geologists. Core from the S.W. SUN 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.

Drilling continues on both the Main SUN Deposit and S.W. SUN Deposit. New assays will be released as they are received from ALS-Chemex. Drilling is planned to continue into September of 2012.

A second drill rig operated by Core One Drilling of Delta, Colorado, is currently testing new targets outside of the known Main SUN and S.W. SUN Deposits. These targets were generated in the SUN District by Andover's 2012 reconnaissance efforts. Results from these drill holes will be reported as they are received. New targets will be addressed for as long as the exploration season allows.

"The drilling at S.W. SUN continues to increase the known size of the deposit and is allowing us to better understand the mineralization controls and structural setting of this deposit," says Kent Turner, Andover's COO. "We will continue to develop a new resource here to add to our Main SUN Deposit resource. We expect to be able to provide a National Instrument 43-101 compliant resource estimation on the S.W. SUN Deposit later this year or early in Q1, 2013."

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.
