The Globe and Mail reports in its Saturday edition that the RCMP and several securities regulators are probing an apparent "pump and dump" stock promotion mail campaign involving Crestview Exploration. The Globe's Niall McGee and Greg McArthur write that in April and May, letters were delivered to households across the country, aggressively promoting Crestview shares, which trades on the Canadian Securities Exchange. The letter claimed investors would strike it rich by buying shares in Crestview. Much of the letter "contained elements that often appear in questionable investment solicitations," wrote Doug Muir, director of enforcement with the British Columbia Securities Commission. Crestview's market value is a mere $8-million. Crestview says it had no role whatsoever in the dissemination of the letter. As a flurry of promotion letters was distributed in April, shares in Crestview ran up from 73 cents to $1.38. A little over a week later, the shares plummeted to 66 cents. Last week, the BCSC and the Alberta Securities Commission confirmed that an investigation has been launched to find out who is behind the letters. The RCMP also confirmed that its Integrated Market Enforcement Team in Calgary is investigating.
