This follows receipt of advice from US Lithium outlining project progress and corporate activities.

Highlights

· A capital raise, issuing 2,000,000 shares @ A$0.12/share raising A$240,000 before expenses associated with the raise. This compares with the Thor acquisition of 2,500,000 shares @ US$0.03/share (approximately A$0.04/share). Thor equity has been diluted to a 20.83% interest in US Lithium.

"US Lithium has made very positive progress in recent months, and we welcome the additional investment at a substantial premium to the original Thor investment."

"The market for lithium continues to grow, and quality assets will be rewarded. We look forward to a successful listing of US Lithium on ASX in due course."
