Niblack Mineral Development Inc. (TSX VENTURE:NIB) ("Niblack" or the "Company")
is pleased to announce that on December 16, 2011 it mailed a notice of meeting,
management information circular (the "Information Circular") and related
documents to its shareholders, optionholders and warrantholders (together,
"Securityholders") in connection with the special meeting of Securityholders to
be held on January 11, 2012 (the "Meeting"). At the Meeting, Securityholders
will be asked to approve the arrangement announced by the Company on October 25,
2011, whereby subject to the terms and conditions of an arrangement agreement
(the "Arrangement Agreement") with Heatherdale Resources Ltd. ("Heatherdale"),
Heatherdale will acquire all of the outstanding common shares in the capital of
Niblack (the "Niblack Shares"), pursuant to a plan of arrangement (the
"Arrangement"). Assuming the Arrangement becomes effective, holders of Niblack
Shares will receive 0.50 common shares of Heatherdale (a "Heatherdale Share")
for each Niblack Share held, each holder of options of Niblack ("Niblack
Options") will receive CDN $0.01 per Niblack Option held, and each Niblack
warrant ("Niblack Warrants") will be deemed to be amended so as to entitle the
holder thereof to acquire that number of Heatherdale Shares that is equal to 50%
of the number of Niblack Shares subject to such Niblack Warrant immediately
prior to the completion of the Arrangement. At the Meeting, the Securityholders
will be asked to approve the Arrangement.


The board of directors of Niblack (the "Niblack Board") has determined that the
Arrangement is in the best interests of Niblack and is fair to the
Securityholders and recommends the Securityholders vote FOR the Arrangement. The
determination of the Niblack Board is based on various factors described more
fully in the Information Circular.


To be effective, the Arrangement must be approved by special resolutions passed
by at least two-thirds of the votes cast by holders of each of (i) the
outstanding Niblack Shares, (ii) the outstanding Niblack Options and (iii) the
outstanding Niblack Warrants present in person or represented by proxy at the
Meeting. Each holder of Niblack Shares on the record date of December 5, 2011
(the "Record Date") is entitled to one vote for each Niblack Share held. Each
holder of Niblack Options on the Record Date is entitled to one vote for each
Niblack Share issuable upon exercise of such holder's Niblack Options. Each
holder of Niblack Warrants on the Record Date is entitled to one vote for each
Niblack Share issuable upon exercise of such holder's Niblack Warrants. The
directors and officers of Niblack have entered into lock-up agreements with
Heatherdale, whereby they have agreed to vote their Niblack Shares and any
Niblack Options and Niblack Warrants held by them in favour of the Arrangement.
The Arrangement is subject to final approval by the Court of Queen's Bench of
Alberta and is subject to the satisfaction of certain other conditions.


In summary, Securityholders should pay particular attention to the following
important dates:




January 9, 2012(1) - Last day to deposit proxies.
January 11, 2012(1)  - Special meeting of Securityholders.
January 13, 2012(2) - Effective time of the Arrangement.
