Trending toward diamonds
Three geological "trends" in northern Alberta are being carefully searched by mining companies for signs of kimberlite, a volcanic rock that often contains diamonds. The Peace River, Wabasca River and Fort Mackay trends cover a large swath of land stretching from Grand Prairie to the Saskatchewan border east of Fort McMurray. The Alberta Geological Survey released data in mid-January from a site northwest of Red Earth Creek that has encouraged companies to step up their operations in the region north of Lesser Slave Lake.
