Additional Copper-Silver Anomalies Found at Sping

October 23, 2007 - Vancouver, British Columbia. Appleton Exploration Inc. (TSX-V.AEX) has received further encouraging geochemical assay results from its 4,600 hectare Sping coppersilver project, north of Smithers, British Columbia. The objectives of the 2007 exploration season were to substantiate the previously documented copper-silver rich limes tone and determine the potential of finding more. This was accomplished with six reconnaissance scale traverses (roughly 1 km apart) across the property, including one over the known area of mineralization. Each traverse involved mapping, prospecting and 100 metre spaced soil sampling.

Outcrops of disseminated silver-rich chalcopyrite (copper) bearing limestone were identified and grab sampled across an area 300 metres wide. Results confirmed documented levels of copper and silver with Appleton’s assays ranging from 0.28% to 1.06% Cu, and 1.1 to 30.0 grams per tonne Ag.

The reconnaissance traverses also identified several other areas of copper-silver anomalies in areas covered by overburden; the most notable fall within a general northwest trend of anomalies developing over 1.5 km with the outcropping mineralized limestone in the centre of that trend. The anomalies are expressed by copper values in soils between 80 and 104 ppm with accompanying silver values in soils between 0.4 and 2 ppm.

The reconnaissance traverses also identified an interesting east-west trending zinc-lead soil anomaly 100 - 150 metres wide and 800 metres long, with zinc values between 433 and 5,760 ppm and lead values between 29 and 318 ppm. This trend is 700 metres south of the silvercopper rich limestone outcrops.

The Company is very encouraged with the 2007 exploration results from the Sping property, which is under 100% option to the Company. Several interesting target areas have been identified and warrant further work to expand and delineate. Mapping, sampling, trenching and success-contingent diamond drilling will follow.

The 2007 Sping exploration program was completed under the direction of Steve Butrenchuk, P.Geol., a Qualified Person as defined in National Instrument 43-101.
