Four of the eight listed companies being probed over the penny stock rout that wiped out billions of dollars in market value last October were asked yesterday to provide more data to the authorities.

These include Annica Holdings, Magnus Energy Group, Blumont Group and LionGold Corp.

The request for further data comes after the Commercial Affairs Department (CAD) seized computers, data storage devices and financial records from eight firms and their subsidiaries starting April 2 as part of a sweeping probe into trading irregularities in Blumont, Asiasons Capital and LionGold Corp.

The CAD yesterday asked Annica and a subsidiary, Nu-Haven Inc, to provide accounting records, minutes of meetings and resolutions and other documents for the period from Jan 1, 2011 to March 31.

Magnus Energy and its subsidiary, Antig Investments, and Wallmans Ltd, a former unit of Antig, were asked to provide similar records for the period from July 1, 2010 to March 31.

LionGold was asked yesterday to provide accounting records and minutes of meetings and resolutions from April 1, 2010 to March 31. It also sought directors' e-mails and those of the adviser to the chairman and e-mail of certain key management personnel.

Documents relating to LionGold's proposed acquisition of Minera IRL were also requested. Both parties agreed on Oct 10 last year to abort negotiations due to the volatility in LionGold's share price.

Blumont, G1 Investments and its wholly-owned unit, Waddells International, were also asked to provide accounting records and other data from Jan 1, 2011 to March 31. The CAD asked for all documents relating to announcements made by Blumont regarding several proposed acquisitions.
