Orvana Formally Commences All-Cash Offer to Acquire Kinbauri Gold Corp. for $0.55 Per Share

TORONTO, ONTARIO, May 25 (MARKET WIRE) --
Orvana Minerals Corp. (TSX: ORV) today announced that it has formally
commenced its all-cash offer of C$.0.55 per share for all outstanding
common shares of Kinbauri Gold Corp. (TSX VENTURE: KNB), a gold
exploration company based in Carp, Ontario. The Company has mailed its
take-over bid circular and relating documentation to Kinbauri security
holders and filed all such documentation on SEDAR.

The offer represents a premium of 39.2% over the closing price of
Kinbauri's common shares on May 8, 2009, the last trading day prior to
the announcement of Orvana's intention to make an offer to acquire
Kinbauri, and a 36.1% premium over the average closing price for
Kinbauri's common shares over the ten-day trading period ended May 8,
2009.

Orvana's offer is open for acceptance until 8 p.m. (Toronto time) on June
30, 2009, unless it is extended or withdrawn. The offer is subject to the
condition that Kinbauri terminate its previously announced proposed
transaction with Glen Eagle Resources Inc., as well as conditions that
are customary for a transaction of this nature. The full details of
Orvana's offer, including the conditions to the offer, are included in
the take-over bid circular and related documentation being mailed to
Kinbauri's security holders and filed on SEDAR.

"We are offering Kinbauri shareholders a choice: tender to our offer and
receive liquidity, value and certainty today or face a risky future with
Kinbauri, whose plan to bring its Spanish properties into production
relies upon uncertain financing and inexperienced management," said Kent
Jespersen, Chairman of Orvana.

Should you have any questions regarding the offer, please contact
Kingsdale Shareholder Services Inc., the information agent in connection
with the offer, at 1-800-749-9052 (toll-free) or 416-867-2272 (outside
North America).

Orvana is a well-established mine operator with an experienced management
team that has collectively brought a number of underground mines into
production. Orvana had cash of approximately US$96.2 million (C$112.5
million) as of March 31,2009, more than sufficient to acquire Kinbauri's
shares and then to develop Kinbauri's Spanish mineral project.
