Of the three dispersion trains, two of them are identified on the west half of GEFA based on microprobe-confirmed results from the final 72 till samples of the September 2014 program.

Recovered KIMs include Cr-pyrope garnets, Mg-ilmenites and chromites.

Previously, the third train was announced on the eastern half of GEFA, and it features an eclogite garnet, chromite, Cr-pyrope garnet, Mg-ilmenites and a second orange garnet.

Alto Ventures CEO Rick Mazur said: "The identification of at least three probable KIM dispersion trains on GEFA within 20km of a near surface diamond bearing kimberlite on the North Arrow Pikoo property is a strong indication that an emerging diamond district is unfolding in the northern SaskCraton.

"Alto looks forward to our team integrating these results with our recently completed high-resolution airborne magnetic survey to identify high-priority kimberlite targets for drilling."

Additional KIM samples are located in the southwest of GEFA, including sample T266 which contains 28 Cr-rich chromites and two Mg-ilmenites.
