Companies reporting major news:

BlackPearl Resources Inc. (TSX:PXX). Oil and gas. Up nine cents, or 7.26 per cent, to $1.33 on 696,848 shares. The developer of a multi-billion dollar oilsands project says approval announced Thursday by the Alberta government is critical to raising money or finding a partner with deep pockets to go ahead with construction. CEO John Festival of BlackPearl Resources says he is relieved after receiving official endorsement for the 80,000-barrel-per-day Blackrod project more than four years after filing an application in May 2012. Analysts estimate the first 20,000-barrel-per-day phase at Blackrod will cost about $800 million to build and Festival says that number is in the ballpark. Detailed estimates will come if the project is approved in future.
