AFRIDI LAKE

Shear Minerals, International Samuel Exploration Corp., New World Resources Corp., and Mantle Resources Inc. today announced results from the spring 2008 exploration program at the Afridi Lake Diamond Project, Northwest Territories. A total of 12 drill holes (1,741 m) were completed that tested 12 priority geophysical targets including the DA1 and DA2 diamondiferous kimberlite pipes. Three holes intersected kimberlite. Drill hole AF08-01 tested a gravity low coincident with a magnetic low of the DA1 kimberlite with a vertical hole and intersected kimberlite at a depth of 9.1 meters. The hole remained in kimberlite to a depth of 186 meters. The kimberlite has been described as crater facies, mud rich with a sand matrix, visible bedding and large autoliths. AF08-02 tested a gravity low between DA1 and DA2, intercepting 0.21 m of kimberlite in a possible fault zone. AF08-03 tested DA2 gravity low and intercepted 0.36 m of fine grained kimberlite, possibly a kimberlite dyke offshoot from the main pipe. Kimberlite was not encountered in the remaining nine holes. Core has not yet been analyzed.

Stage 1 exploration program completed and has confirmed eight initial priority geophysical targets suggestive of kimberlites ready for drill testing. The airborne gravity survey at the Afridi project clearly defined the known kimberlites as well as outlined a number of potential new targets that will be drill tested in the early spring of 2008.

A 10-person crew completed ground follow-up surveys where more than 50 targets were ground checked, and a total of 206 line kilometres of ground magnetics were completed as well as 791 gravity stations. As a result, eight targets have been chosen for follow up with spring drilling. In June and July 2007, a 2,850 line kilometers high resolution airborne gravity gradient survey was completed. It was proven that the density contrast between the surrounding rock and the known kimberlites was great enough to register an interpretable gravity gradient anomaly of two hectares or larger.
