Tinka to Acquire Darwin; Arranges $4.54 Million Financing

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR RELEASE, PUBLICATION,
DISTRIBUTION OR DISSEMINATION DIRECTLY, OR INDIRECTLY, IN WHOLE OR IN PART, IN
OR INTO THE UNITED STATES. 


Tinka Resources Limited ("Tinka") (TSX VENTURE:TK) and Darwin Resources Corp.
("Darwin") (TSX VENTURE:DAR)(PINKSHEETS:DARWF)(FRANKFURT:DWU) jointly announce
that they have entered into a binding term sheet (the "Agreement") whereby Tinka
has agreed to acquire through a statutory plan of arrangement (the
"Arrangement") all of the outstanding shares of Darwin. Under the terms of the
Arrangement, Darwin shareholders will receive one Tinka common share (a "Tinka
Share") for each five and one half Darwin common shares (the "Darwin Shares")
resulting in the issuance of 6,131,725 Tinka Shares in exchange for 33,724,488
Darwin Shares. The offer values Darwin at $0.066 per Darwin Share, based on
Tinka's April 11, 2014, closing price on the TSX.V of $0.365.


As part of the Arrangement, Tinka will undertake a private placement (the
"Private Placement") of up to 16,509,090 units of Tinka (the "Units") at a price
of $0.275 per Unit for gross proceeds of up to $4.54 million. Each Unit will be
comprised of one Tinka Share and one half of one share purchase warrant, with
each whole warrant (a "Warrant") exercisable to acquire an additional Tinka
Share at a price of $0.365 for a period of twenty four months. Sentient Global
Resources Fund IV, LP ("Sentient") has agreed, subject to certain conditions, to
subscribe for 12,872,727 Units under the Private Placement. 


Andrew Carter and Graham Carman, President and CEO of Tinka and Darwin,
respectively, jointly state: "We believe this transaction will be a good outcome
for the shareholders of both Tinka and Darwin, and has our combined support. The
acquisition of Darwin comes with funding for Tinka so it can continue with its
drill program at the Ayawilca and Colquipucro projects in Peru. It also brings
to the Tinka share register a strong institutional shareholder in the Sentient
Group, an independent private equity investment firm specialising in the global
resources industry, and new management with a track record in advanced zinc
projects in Peru. Darwin shareholders will gain exposure to Tinka's highly
prospective Ayawilca zinc project along with an inferred silver resource at
Colquipucro, both of which we believe have strong growth potential."


Terms of Agreement



--  Darwin shareholders will receive one Tinka Share for each five and one
    half Darwin Shares held. 
    
--  All outstanding Darwin options and warrants will be adjusted and
    exchanged in accordance with the same exchange ratio. 
    
--  Upon closing of the Arrangement, Dr. Graham Carman, President and Chief
    Executive Officer of Darwin, will be appointed President and Chief
    Executive Officer and a director of Tinka. 
    
--  Closing of the Arrangement and Private Placement (the "Closing") is
    expected to occur approximately ten days after receipt of Darwin
    shareholder approval. 
    
--  Tinka will receive up to $4.54 million in Private Placement proceeds. 
    
--  Tinka will gain access to Darwin's mineral exploration portfolio located
    in Peru. 
    
--  Darwin shareholders gain exposure to Tinka's Ayawilca and Colquipucro
    zinc, silver, copper and lead projects (collectively, the "Ayawilca
    Colquipucro Project"). 



The parties will negotiate in good faith and enter into definitive agreements
relating to the Arrangement and Private Placement. 


The Arrangement will be subject to standard closing conditions for a transaction
of this nature including, without limitation, receipt of all required
shareholder, court and regulatory approvals by July 31, 2014. 


The Agreement may be terminated by written agreement of Sentient, Darwin and
Tinka, by Sentient upon written notice to Darwin or Tinka, or by any party if
Closing has not occurred by September 15, 2014.


The Private Placement 

Under the terms of the Private Placement Sentient has agreed, subject to certain
conditions, to purchase 12,872,727 Units. Within ten days from the date hereof,
Sentient will purchase 1,818,182 Units for aggregate gross proceeds of
approximately $500,000 (collectively, the "1st Tranche Units").
Contemporaneously with the Closing, Sentient will purchase an additional
11,054,545 Units for aggregate gross proceeds of approximately $3,040,000 (the
"2nd Tranche Units"). An establishment fee equal to 5% of the aggregate
subscription price of the 1st Tranche Units and the 2nd Tranche Units will be
paid by Tinka to Sentient by issuing an additional 643,636 Units. Up to
3,636,363 Units for aggregate gross proceeds of approximately $1 million may be
purchased by subscribers identified by Darwin (the "President's List
Subscribers"). 


Sentient and its affiliates currently hold 10,112,032 Darwin Shares and share
purchase warrants (collectively, the "Darwin Warrants") entitling Sentient to
acquire up to 3,400,000 Darwin Shares. Sentient has agreed to cancel its Darwin
Warrants as part of the Arrangement. Accordingly, upon Closing of the
Arrangement and the Private Placement, Sentient will hold 15,354,915 Tinka
Shares and 6,758,182 Warrants (the "Sentient Warrants") to acquire 6,758,182
Tinka Shares, representing approximately 19.98% of the Tinka Shares outstanding
on completion of the Arrangement assuming full exercise of the Sentient
Warrants. 


Upon Closing, for so long as Sentient owns 5% or more of the outstanding Tinka
Shares (on a diluted basis), Sentient will have the right to nominate one
individual to the Tinka board of directors. In the event that Sentient owns 20%
or more of the outstanding Tinka Shares (on a diluted basis), Sentient will have
the right to nominate two individuals to the Tinka board. 


Sentient will be granted a pre-emptive right to maintain its diluted percentage
interest in the outstanding Tinka Shares in connection with any future issuances
of Tinka securities other than in connection with Tinka securities issued
pursuant to Tinka's employee stock option plan or any convertible securities of
Tinka outstanding as at the date hereof or contemplated under the Private
Placement. 


The obligation of Sentient to proceed with the Private Placement is subject to
Sentient being satisfied, in its sole discretion, with its due diligence review
of Tinka anticipated to be completed on or before May 30, 2014. 


Tinka will use the proceeds from the Private Placement as follows: (i) the
proceeds from the 1st Tranche Units will be to provide interim working capital
for Tinka; and (ii) the proceeds from the 2nd Tranche Units and the President's
List Subscribers will be used for conducting exploration and resource
development work on the Ayawilca Colquipucro Project and the combined
Tinka/Darwin exploration portfolio and for general working capital purposes. 


Tinka has agreed for a period of six months following closing of the Private
Placement, that it will not, without the written consent of Sentient, offer: (i)
Tinka common shares or units at a price that is less than $0.275; or (ii) share
purchase warrants that are exercisable into Tinka Shares at a price that is less
than $0.365 per share.
