Appleton Intersects 31 metres of 2.79 g/t Au at Manalo

June 15, 2010 Vancouver, British Columbia. Appleton Exploration Inc. (AEX - TSX.V) is pleased to announce initial results from its spring 2010 reverse circulation (RC) and aircore (AC) drill campaign on the northern and southern segments of the Dialafara Prospect on the Manalo Gold Project, Mali, West Africa.  Highlights include 31 metres of 2.79 grams per tonne (g/t) gold (uncut) in a broader interval of 61 metres of 1.62 grams per tonne gold (uncut).  Follow-up analysis by screen metallics methods returned 1.43 g/t Au over the 31 metre interval and 0.95 g/t  Au over the 61 metre interval, confirming gold mineralization.

The drill results above are part of the 4,300 metre, 37 hole RC drill program and 3,771 metre, 67 hole AC drill program conducted during March and April 2010.  Maps showing drill collars locations and tables of metre by metre results for each of the intervals tabled in this news release are available on the Manalo Current Exploration Page on the Company's website: www.appletonexploration.com.

Appleton is earning a 100% interest from Delta Exploration Inc., a wholly-owned subsidiary of Rockgate Capital Corp.

Dialafara South Segment

Twenty-nine RC drill holes totalling 3,328 metres tested along approximately 900 metres of the Dialafara South structure.  To date, results have been received for 5 holes from this area.  MDL-10-086, reported above, was collared under the central artisanal workings where mapping indicates the presence of northeast and northwest trending quartz veins in a stockwork.  MDL-10-086 is situated between holes MDL-09-053 and MDL-09-054, which returned 1.58 g/t Au over 10 metres and 3.32 g/t Au over 18 metres, respectively, in a west-northwest-trending quartz-rich structure.  Significantly, gold mineralization in MDL-10-086 extends 10 metres into rock without quartz veining.

In addition, four holes, MDL-10-074 to MDL-10-077, located about 150 metres northwest of MDL-10-086 in the northwest artisanal workings on the Dialafara South structure intersected weakly mineralized quartz veining proximal to the main structure. Their highlights are tabled below. These four holes are in the vicinity of previous drilling, which included 27 metres averaging 0.50 g/t Au from MDL-09-068.

Dialafara North Segment

MDL-10-079 intersected high-grade gold mineralization associated with quartz veining at the bottom of the hole. MDL-10-079 returned 6.54 g/t Au across 10 metres by fire assay and 2.30 g/t Au by screen metallics methods.  MDL-10-079 was collared 50 metres northwest of section MDL-09-046 and MDL-09-062, which intersected 2.80 g/t Au over 11 metres and 1.03 g/t Au over 9 metres, respectively.  MDL-10-080 was collared too far to the southwest so failed to reach the mineralized structure.  Thus, this mineralized zone remains open to the northwest, heading toward mineralization identified some 750 metres to the northwest.

MDL-10-081 to 085 tested 400 to 700 metres southeast of MDL-10-079, southeast of the Dialafara north artisanal workings.  MDL-10-081 was collared approximately 60 metres southeast of MDL-09-065, which intersected 7 metres of 34.97 g/t Au.

Dialafara North Segment - NW Step-out

One RC hole, MDL-10-078, was drilled to test low-grade mineralization intersected in aircore drilling in 2009.  MAC-09-001 intersected 0.17 g/t Au across 30 metres.  MDL-10-078 intersected anomalous gold values between 95 and 116 metres downhole, including 1.28 g/t Au over 2 metres.  A new fence of aircore drilling comprising 8 holes stepped 100 metres to the south, intersecting an 8 metre interval averaging 0.73 g/t Au in MAC-10-099.  This structure is on strike with Dialafara north segment mineralization.  MAC-10-096 also intersected 10.65 g/t Au over 1 metre in a 4-metre moderately quartz-rich structure.

All samples were analyzed by 50 gram fire assay.  Samples identified in potentially mineralized zones or that returned anomalous (>0.10 g/t) gold values were checked with screen metallics analysis.  Previous work suggests that Manalo hosts moderate coarse gold.

Quality Control and Assurance

The widths and grades reported are drill intercept widths and may not represent the true width of mineralization. Individual gold assays have not been cut but high grade samples have been separately reported in the table above. Samples are reverse circulation cuttings collected using a cyclone in 1 metre intervals that are riffle split at the drill site. Samples are assayed by fire assay (50 gram charge). Zones of quartz veining and limonite were submitted for check assays by the screen metallic method in order identify the presence and significance of coarse gold in samples. The primary laboratory is ALS Chemex in Bamako, an ISO 17025 certified laboratory. Standard, blank and duplicate samples were inserted throughout the sample sequence as quality control checks.  Both Chris Wild, P.Eng. and Paul Cowley, P.Geo., director of Appleton, are qualified persons for the drilling campaign.

About Mali

Mali is the fastest growing gold producing country in Africa. Production in 2007 amounted to 2 million ounces of gold making Mali Africa's third-largest gold producer after South Africa and Ghana. AngloGold Ashanti Limited, one of the largest gold mining companies in the world, has interests in three operating mines in Mali: Sadiola, Yatela and Morila.
