Appleton Exploration Commences 2007 Exploration Field Programs on its Spences Bridge Gold Belt Project

May 14, 2007 - Vancouver, British Columbia. Appleton Exploration Inc. (TSX-V: AEX) has commenced its 2007 exploration programs on its Spences Bridge Gold Belt Project. The Company’s Spences Bridge Gold Belt Project, comprised of five properties covering 74,000 hectares, lies within the Spences Bridge Gold Belt in south central British Columbia. The Spences Bridge Gold Belt is emerging as a new epithermal gold camp after recent discoveries by Almaden Minerals Ltd., Consolidated Spire Ventures Ltd. and Strongbow Exploration Inc.

Appleton is led by a seasoned team of explorationists and mining professionals. The Company was incorporated on June 23, 2006 as a private company in British Columbia, raising funds to complete a $350,000 exploration program on its Spences Bridge Gold Belt Project and to proceed with an initial public offering. The Company commenced trading on the TSX Venture
Exchange on May 14, 2007.

The Company’s 2006 exploration program was successful in locating gold-in-soil and/or goldin-bedrock anomalies on each of the properties in its Spences Bridge Gold Belt Project. A brief summary of the 2006 exploration results for each of the five properties follows.


Dora

Exploration was successful in locating the Breccia Vein, a 1 metre wide SE trending quartz breccia vein. Grid geochemical soil samples returned values ranging from 10 parts per billion (“ppb”) Au to 280 ppb Au. Soil geochemistry was successful in tracing the vein 1000 metres with gold-in-soil values from 5 ppb to 40 ppb. The west trending, 7-10 metre wide Fault Zone of alteration and shearing returned values from 5 ppb to 140 ppb Au from limonite gouge zones within the structure. This zone was traced approximately 600 metres by soil geochemistry. Two additional soil grids – the Silt and the Mare – were established. Gold-in-soil and/or goldin-silt anomalies were located on each of the Silt and Mare grids.


Clapperton

Exploration located a north trending, 30-40 metre wide zone of alteration and shearing hosting individual carbonate + quartz seams and veins range from 5-10 centimetres in width. Geochemical rock values from 15 ppb Au to 60 ppb Au were obtained from the individual seams and veins. The west edge of the Clapperton soil geochemical grid appears to have located the strike projection of the zone.


Spence

Road soil geochemistry located a 600 metre section ranging from 10 ppb Au to 20 ppb Au. A soil grid over the area was successful in confirming the anomalous area.


McKay
Road soil geochemistry identified two zones of continuous gold-in-soil anomalies along with individual values ranging from 10 ppb Au to 40 ppb Au. Soil geochemical grids confirmed and expanded the southern zone, but did not confirm the north zone.


Stobart / Fame

Road soil geochemistry identified two areas that were followed up with soil geochemical grids. Gold-in-soil anomalies were located on both grids, requiring further follow-up. Additional gold-in-soil anomalies found during the 2006 Phase I road soil sampling program will also require follow up.


Mineralization on the Fame Option consists of four main showings associated within northwest trending structural lineaments: Discovery, Kelsch, Double Diamond and Twilight. The zones are epithermal veins to veinlets and breccias. Historical grab sampling obtained values from 5 ppb to 14,800 ppb Au over narrow widths.

The Company completed a soil grid over the Twilight Zone where two linear gold-in-soil anomalies were identified. The Discovery, Kelsch and Twilight zones were also examined with preliminary grab sampling returning values from 5 ppb to 2270 ppb Au.

Appleton’s 2007 exploration program will follow the recommendations of the Company’s independent Qualified Person, Stephen Butrenchuk, P.Geol. in his technical report filed in support of the Company’s initial public offering. This program will concentrate on the Dora Property. Soil grids will be tightened and expanded over the Breccia and Fault Zones. The grids will be prospected and mapped in detail. A proton magnetometer survey will then be completed over the grids to assist in the tighter definition of anomalies. Upon completion of the geology, geochemistry and geophysics, a program of excavator trenching will be initiated to evaluate the geochemistry and geophysical anomalies.
