"SUN-12-35 confirms the presence and character of the mineralization on the northeastern extension of the Main SUN Deposit," says Kent Turner, COO of Andover Mining Corp., "and should serve to help increase our resources along strike in that direction when we have completed the seasons work and Mine Development Associates of Reno, Nevada completes a National Instrument 43-101 compliant resource calculation and a PEA for the Main SUN Deposit after the 2012 drill campaign is completed and the assays and QA/QC work have been completed. We continue to be pleased with the results of our 2012 program on our deposits within this emerging mineral belt."

Drilling will continue 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.

Drill core from SUN 12-35, completed on 27 July 2012 was logged, split and boxed on site by Andover's geologists. Core from SUN 12-35 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.
