July 15, 2010 Vancouver, British Columbia. Appleton Exploration Inc. (AEX - TSX.V) is pleased to announce results from a further thirteen reverse circulation (RC) holes focused on the southern segment of the Dialafara Prospect on the Manalo Gold Project, Mali, West Africa.  These new results, in conjunction with previous drilling to date, now define a minimum 450 metre strikelength trend of encouraging gold mineralization. The latest results include: 61 metres of 1.45 grams per tonne (g/t) Au, 27 metres of 1.50 g/t Au and 3 metres of 26.88 g/t Au.

Drill results last reported on June 15, 2010 focused on testing the northwesternmost 250 metre strikelength of the Dialafara Southern Segment. The drill results reported in this release with holes MDL-10-087 through MDL-10-099 tested a 700 metre strikelength of the Dialafara Southern Segment, overlapping 150 metres with the previous reporting. These new results, in conjunction with previous drilling to date, now show good signs of lateral and downdip continuity to gold mineralization along a minimum 450 metre strikelength. Other drilling previously reported along this 450 metre strikelength include hole MDL-10-086 with 61 metres of 1.62 g/t Au hole and hole MDL-09-54 with 18 metres of 3.32 g/t Au.

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 collar 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. There are still 10 holes pending results from this campaign, all on the Dialafara Southern Segment.

The Company also wishes to announce that it has completed 39 aircore holes totaling 2,586 metres on its Sirabada target and 52 aircore holes totaling 1,784 metres on its Mansaya target, both of which are part of the Manalo Project. Results are pending from this program.

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

Quality Control and Assurance

All samples were initially analyzed by 50 gram fire assay.  Samples in high quartz intervals or those returning anomalous (>0.10 g/t Au) gold values were analyzed by screen metallic assay method, in order to identify the presence and significance of coarse gold in samples. All intercepts presented in this news release are screen metallic assay. 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. 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.
