TORONTO, ONTARIO--(Marketwire - Aug. 19, 2011) - On June 29, 2011, Niocan Inc. ("Niocan" or the "Company") (TSX:NIO) announced that the Company had entered into a binding term sheet with Nio-Metals Holdings LLC ("Nio-Metals") pursuant to which Nio-Metals has agreed to purchase by way of private placement a minimum of 2,000 units (each, a "Unit") and a maximum of 4,000 Units at an issue price of $1,000 per Unit, representing aggregate gross proceeds to the Company of a minimum of $2 million and a maximum of $4 million (the "Private Placement"). The Company has received interest from additional investors in participating in the Private Placement and expects to raise gross proceeds of between $3 million and $4 million. The Company expects the following changes to the terms of the previously announced private placement:

• each Unit would be comprised of one $1,000 principal amount of secured debenture ("Debenture") and 520 transferable common share purchase warrants of Niocan (each, a "Warrant"), which represents an increase in the numbers of Warrants comprising one Unit from 370 Warrants;

• each Warrant would expire on the day that is 3 years from the date of the issuance of the Warrant, rather than 2 years; and

• each Debenture would bear interest at a rate of 12% per annum, as opposed to 10%.
