The Calgary, Alberta-based company plans to sell 28 million units, each made up of one share and one half purchase warrant, priced at nine cents.
Each purchase warrant gives the holder a right to buy another common share of Celeste for a price of 12.5 cents for a 30 month period, after the transactions close.
Proceeds from the placement will go toward boosting Celeste's interest in Cornish Minerals Limited to 25 percent from 19 percent.
Additionally, the company can further increase its stake in Cornish Minerals to either 50 or 60 percent, provided it completes required funding commitments by September 30, 2013.
Liberty Metals & Mining Holdings, a unit of Boston-based Liberty Mutual Insurance, plans to subscribe for up to 23.3 million units. Liberty, which is a control person of Celeste, would hold about 48 percent of the company's common shares and 85 percent of the outstanding warrants.
Separately, both companies have amended a previous agreement which will now allow Liberty to elect two nominees to Celeste's board. At the moment, Liberty can only designate one nominee.
