Abstract Stonegate Agricom Ltd. is currently conducting exploration and development drilling of the Paris Hills Project located in Bear Lake County, southeastern Idaho, 3.2 kilometres west of the towns of Paris and Bloomington and includes the former Bloomington Canyon, Consolidated (Little Canyon) and Paris Canyon (McIlwee) mine sites. The Paris Hills Project encompasses an area of approximately 856 hectares. Property holdings consist of three patented lode mining claims and 16 contiguous fee parcels (some with federal mineral reservations). It is located approximately 72 kilometres south of active phosphate mining operations at Soda Springs (regional operators include Agrium Inc., Monsanto Company and J.R. Simplot Company).
The Paris Hills Project is located near the centre of the western phosphate field which constitutes the most extensive phosphorite beds in the United States. Phosphate beds of the western phosphate field occur within the Phosphoria Formation of Permian age. Phosphate mineralized beds occur in the overturned limb and the horizontal limb of the Paris Syncline. Grades and thicknesses in both the western overturned limb and the eastern horizontal limb of the anticline are similar. The vast majority of potential mineralization occurs in the horizontal limb which underlies most of the Paris Hills Project.

Mineralization in the overturned limb has a strike length of over three kilometres and extends from the surface to a depth exceeding 300 metres depending on location along the north-trending strike of outcrops. Depths of the horizontal limb range from surface along the north side of Bloomington Canyon to estimated depths of 915 to 1,035 metres at Paris Canyon.
Access is provided by county-maintained roads in the canyons of Bloomington Creek and Paris Creek. These are all-weather roads that are cleared of snow throughout the winter. From these roads, access onto the Project site is gained via a series of trails, used primarily by ranchers to manage grazing of cattle, which have been variably improved with the commencement of drilling in the third quarter of 2010.

Infrastructure in the area is excellent. The project is located adjacent to a highway and close to Union Pacific freight services. The track through Montpelier connects into the Union Pacific Railroad system at Pocatello, Idaho and Green River, Wyoming. Bear Lake County Regional Airport serves the general aviation needs of the local communities. The airport is located between Paris and Montpelier, with commercial air service available in Pocatello, Idaho and Idaho Falls, Idaho to the northwest, Jackson, Wyoming to the northeast, and Salt Lake City, Utah, to the south. Power and water are available locally.
The property contains an Inferred resource of 109.6 million tonnes at 23.6 percent P2O5 over two horizons. The phosphate zones have a strike length of over 3 km and extend from surface to a depth of at least 600m. Drilling commenced late in the third quarter of 2010 and is planned to continue through 2011. The drilling was planned to target an area of potentially higher grade phosphate mineralization and better define/upgrade the current resources. The presentation will provide an update on the geology and mineralization at the project.
