Andover Mining Corp. reported the discovery of new copper, lead, zinc, silver and gold rich massive sulfide system in the SUN District in the Ambler Mineral Belt, northwest Alaska. Assays have been received from drill hole STU12-01, which targeted outcropping mineralization that was mapped and sampled by Andover's field team during this year's reconnaissance efforts in the SUN District.

The STU target was one of 6 new potential targets identified during 2012. These reconnaissance efforts were previously reported in the new release dated August 8, 2012. The STU target area is located approximately 8 km west of the Main SUN and S.W. SUN deposits where most of Andover's 2012 efforts have been focused.

Drill hole STU12-01 was completed on August 16, 2012. The drill hole was abandoned prior to reaching its planned depth due to drilling difficulties. Based on this successful drill hole, a second hole, STU12-02, was designed as a large down-dip step out hole but encountered drilling difficulties and failed to reach the mineralized zone.

Andover did not complete any additional holes at STU before the field season in the district was concluded.
