Augyva Mining Resources Inc. Announces the Withdrawal of its Intention to Acquire Niocan Inc.

LA MACAZA, QUEBEC--(Marketwire - May 6, 2011) - Augyva Mining Resources Inc. (TSX VENTURE:AUV) (« Augyva ») previously announced on January 12 and 13, 2011 that it had the intention to make an offer to acquire all of the issued and outstanding common shares of Niocan Inc. (TSX:NIO) (« Niocan ») in exchange of one and a half (1.5) common share of Augyva and a cash payment of ten cents (C$0.10) for each common share of Niocan, the whole by way of a formal take-over bid (the « Offer »).

Niocan announced on May 4, 2011 that it has entered into a binding letter of intent with Forbes & Manhattan, Inc. pursuant to which Forbes & Manhattan, Inc., its affiliates and/or assigns would provide Niocan with the lead order for a private placement of 5,157,000 common shares of Niocan at a price of $1.15 per share. Niocan has agreed to a 16 day exclusivity period ending on May 20, 2011 (the « Exclusivity Period ») to allow the completion of due diligence and the negotiation of a definitive subscription agreement. During the Exclusivity Period Niocan shall not be permitted to discuss, negotiate or solicit competing financing transactions or the sale of Niocan's assets with any other person.

In light of such announcement, Augyva announced today its decision to withdraw its intention to make an offer to acquire all of the issued and outstanding common shares of Niocan. Consequently, Augyva shall not pursue the contemplated Offer. Given the Exclusivity Period, the private placement contemplated by Niocan can be considered as defensive tactics taken by Niocan in response to Augyva's intention to make the Offer and may have the effect of denying Niocan shareholders the ability to make a fully informed decision on the Offer.
