CALGARY, Alberta, Canada, May 11, 2012 /CNW-AsiaNet/ –

/NOT FOR DISSEMINATION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION
IN THE UNITED STATES/

Terra Nova Minerals Inc. ("Terra Nova" or the "Corporation") is pleased to
announce that further to the news releases dated March 26, 2012 and May 7, 2012
in respect of Australian Foreign Investment Review Board approval, it has
signed a definitive agreement ("Definitive Agreement") with Holloman Energy
Corporation ("Holloman") of Houston, Texas to acquire, through its wholly-owned
subsidiary Terra Nova Resources Inc., an Alberta corporation, up to a 55%
working interest in two onshore petroleum exploration licenses (the
"Acquisition") located on the western flank of the Cooper Basin in the State of
South Australia, namely PEL 112 (comprised of 2,196 square kilometers) and PEL
444 (comprised of 2,358 square kilometers) (collectively, the "Licenses" and
individually a "License"). Eli Sakhai ("Sakhai"), an individual resident in
New York, USA and Australian-Canadian Oil Royalties Ltd. ("ACOR"), a British
Columbia corporation having offices in Cisco, Texas, each holding a 16.6665%
interest in the Licenses, have been made parties to the Definitive Agreement.
Holloman currently owns a 66.6670% working interest in the Licenses.
(Holloman, Sakhai and ACOR are referred to collectively in this press release
as the "Current Working Interest Holders").

The Corporation is also pleased to announce that, together with Macquarie
Private Wealth Inc. (Canada) ("Macquarie") acting as agent on a commercially
reasonable efforts agency basis, it has today closed the previously announced
brokered private placement offering ("Offering") of units ("Units") for
aggregate gross proceeds of CAD$10,652,075.

The Definitive Agreement

Under the letter of intent, the Corporation paid a non-refundable fee of
USD$100,000 (the "Fee") to Holloman. In accordance with the Definitive
Agreement, within ten business days of the later of: (i) the date of the
Definitive Agreement; and (ii) the date that the Acquisition is conditionally
approved by the TSX Venture Exchange (the "Exchange"); (the "Effective Date"),
the Corporation shall issue to the Current Working Interest Holders in
accordance with their pro rata working interests 1,000,000 common shares of
Terra Nova ("Common Shares"), which shares shall be subject to applicable
statutory and Exchange hold periods. These consideration shares have been
conditionally approved for listing by the Exchange.

Pursuant to the Definitive Agreement, Terra Nova will pay USD$250,000 to
Holloman which, after execution, shall be non-refundable and for Holloman’s
unrestricted use. Within 10 days from the Effective Date, Terra Nova shall pay
AUD$4,700,000 into the trust account of an escrow agent agreed upon by the
parties ("Escrow Agent") to be used for the completion of seismic acquisition
programs sufficient to meet the minimum seismic acquisition requirements for
PEL 112 and PEL 444, respectively, as well as the interpretation of the
acquired data. Upon completion of a seismic program on PEL 112 or PEL 444, as
the case may be, Terra Nova shall earn a 20% working interest in that License.

Also in accordance with the Definitive Agreement, on or before November 1,
2012, Terra Nova shall pay to the account of the Escrow Agent an additional AUD
$4,500,000 which funds shall be used by Terra Nova to conduct a three well
drilling program on the Licenses (the "Initial Well Program"), with a minimum
of one well to be drilled on each License. In the event that any well drilled
as part of the Initial Well Program tests positively for commercially viable
production of oil or gas, Terra Nova is responsible to pay 50% of the total
aggregate completion costs of such well, with the Current Working Interest
Holders responsible for the remaining 50% of such costs, in accordance with
their respective working interests.

Further, at Terra Nova’s option and on or before March 1, 2013 or within
90 days of completion of the third well in the Initial Well Program, the
Corporation may pay into trust an additional AUD$4,500,000, which funds are to
be used to conduct an additional three well drilling program on the Licenses
(the "Optional Well Program"), with a minimum of one well to be drilled on each
License, and with the same responsibilities for completion costs for wells
testing positive for commercial production as under the Initial Well Program.

Upon drilling and abandonment or completion of each well within (i) the
Initial Well Program and (ii) the Optional Well Program, within certain
designated time frames, Terra Nova shall be deemed to have earned an additional
5.8333% working interest in each of the Licenses for a total of approximately
35% in all three wells (55% including the seismic earning entitlement).

Terra Nova shall act as operator with respect to all drilling work
contemplated by the Definitive Agreement. Holloman shall be granted the right
to appoint a nominee to the Board of Directors of Terra Nova.

In the event any well drilled in connection with the Initial Well Program
or the Option Well Program demonstrates commercial viability, and Terra Nova
has elected to complete such well (a "Successful Well"), Terra Nova shall be
entitled to a preferential recovery of an amount equal to one hundred percent
of the costs it has paid to drill that Successful Well (a "Successful Well Cost
Recovery Amount"). Terra Nova shall receive and be entitled to 80% of
production from the Successful Well until either: (a) such Successful Well has
ceased production and is subsequently abandoned; or Terra Nova has received Net
Revenue attributable to the Successful Well equal to the Successful Well Cost
Recovery Amount; following which, the parties shall be entitled to a working
interest share of the production equal to their working interest at the time
the oil and gas is produced in accordance with the joint operating agreement.
"Net Revenue" attributable to a Successful Well shall be the gross proceeds
from Terra Nova’s sale of its 80% of the oil and gas from the Successful Well,
less royalties, taxes, and reasonable sales, marketing and transport costs.

The Definitive Agreement may be terminated in the following circumstances:
(i) in the event the Effective Date does not occur by June 4, 2012; (ii) by
Terra Nova at any time before it has earned the Farm-In Interest in a License
upon providing written notice of such termination to each of the Current
Working Interest Holders, provided that it has paid the Fee and has issued the
Common Shares to the Current Working Interest Holders. In the event Terra Nova
terminates the Definitive Agreement, it shall not be entitled to any interest
in a License unless it has satisfied its earning obligations in respect of such
License (in which case Terra Nova shall be entitled to the interest it has
earned in the relevant Licence) and shall not be entitled to any refund,
reimbursement or return of amounts paid to others or the Common Shares issued
to the Current Working Interest Holders under the Definitive Agreement; (iii)
by Terra Nova if any of the Current Working Interest Holders is in breach of
the material terms of the Definitive Agreement, which fails to go uncured
within 30 business days of receipt by the Current Working Interest Holder of
notice of such breach; or (iv) by any of the Current Working Interest Holders
if Terra Nova is in breach of the material terms of the Definitive Agreement
which fails to go uncured within 30 business days of receipt by Terra Nova of
notice by of such breach; provided, however, that if either ACOR or Sakhai
wishes to terminate the Definitive Agreement in accordance with the foregoing,
Holloman shall have the option but not the obligation to substitute itself or a
third party to undertake Terra Nova’s remaining obligations under the
Definitive Agreement, including without limitation any uncompleted Earning
Obligations, in exchange for the right to earn an aggregate 55% working
interest in each of the Licenses in accordance with the terms of the Definitive
Agreement.

The Exchange conditionally accepted the Acquisition on April 20, 2012,
subject to standard conditions, including receipt of an executed Definitive
Agreement, a satisfactory title report, and the approval of the Australian
Foreign Investment Review Board which approval was granted on May 3, 2012.
Following final approval, Terra Nova will be categorised as an ‘oil and gas
issuer’ on the Exchange.

The Licenses

Estimated quantities of resources disclosed herein have been prepared by
Apex Energy Consultants Inc., an independent qualified reserves evaluator, as
set out in its report entitled "Resource Study on PEL112 and PEL444 South
Australia Prepared for Terra Nova Minerals Inc." dated April 18, 2012 and
effective March 20, 2012 (the "Apex Report"). The Apex Report was prepared in
accordance with National Instrument 51-101 – Standards of Disclosure for Oil
and Gas Activities.

Pursuant to the Definitive Agreement, Terra Nova has acquired the right to
acquire from Holloman up to a 55% working interest in PEL112 and PEL 444,
located within the Cooper/Eromanga Basin in the northeast corner of the state
of South Australia. The total land holdings for each License along with the
average working interest held by Holloman are as follows:

Gross Undeveloped Acres Net Undeveloped Acres Average Working Interest
PEL 112 542,643 361,780 66.67%
PEL 444 582,674 388,469 66.67%
Total 1,125,317 750,249 66.67%

The Licenses are highly prospective for the discovery of oil. Both
Licenses are on trend with several discoveries made in the area. The
structures on PEL 112 and PEL 444 are defined by 2D seismic data acquired from
South Australia government sources and from Holloman.

In accordance with the Apex Report, PEL 112 has prospective resources with
a high estimate (P10) of 114 MMBLs and low estimate (P90) of 27.5 MMBLs. PEL
444 has prospective resources with a high estimate (P10) of 21 MMBLs and low
estimate (P90) of 6.0 MMBLs.

There is no certainty that any portion of the resources will be
discovered. If discovered, there is no certainty that it will be commercially
viable to produce any portion of the resources.

"Prospective Resources" are those quantities of petroleum estimated, as of
a given date, to be potentially recoverable from undiscovered accumulations by
application of future development projects. Prospective resources have both an
associated chance of discovery and a chance of development. Prospective
Resources are further subdivided in accordance with the level of certainty
associated with recoverable estimates assuming their discovery and development
and may be subclassified based on project maturity.

"Low Estimate or P90" means a conservative estimate of the quantity that will
actually be recovered from the accumulation. It is likely that the actual
remaining quantities discovered will exceed the low estimate. If probabilistic
methods are used, there should be at least a 90 percent probability that the
quantities actually recovered will equal or exceed the low estimate.

"High Estimate or P10" means an optimistic estimate of the quantity that
will actually be recovered. It is unlikely that the actual remaining
quantities recovered will exceed the high estimate. If probabilistic methods
are used, there should be at least a 10 percent probability tha the quantities
actually recovered will equal or exceed the high estimate.

Cancellation of Options

The 760,000 options issued to the former directors and officers of the
Corporation, exercisable at $0.53, have been cancelled with the agreement of
the holders.

The Offering

Terra Nova has entered into an agency agreement dated effective March 23,
2012 (the "Agency Agreement") with Macquarie acting as agent on a commercially
reasonable efforts agency basis, pursuant to which Terra Nova has sold Units
for aggregate gross proceeds of CAD$10,652,075. The Units were offered at a
price of CAD$0.25 per Unit and are comprised of one Common Share and one share
purchase warrant ("Warrant"). Each Warrant entitles the subscriber to purchase
an additional Common Share at a price of CAD$0.30 for 24 months from the date
of closing. Upon provision of 30 days notice to subscribers, the expiry date of
the Warrants will be accelerated if the Common Shares trade in excess of
CAD$0.70 for 20 consecutive trading days. The Agent was granted an option to
increase the size of the Offering by up to 10% which was exercised in part. In
connection with the Offering, the Agent has received a cash commission equal to
8% of the gross proceeds raised and agent’s options to purchase that number of
Common Shares equal to 8% of the total number of Units sold (the "Agent’s
Options"). The Agent’s Options are exercisable at a price of CAD$0.25 per
Common Share for a period of 24 months from the Closing Date. The Agent has
also been reimbursed for its expenses in relation to the Offering.

The Common Shares and Warrants comprising the Units, Agent’s Options and
Common Shares issued on the conversion or exercise of such securities, as
applicable, will be subject to a hold period of four months and one day from
the closing date in accordance with the rules and policies of the TSX Venture
Exchange and applicable Canadian securities laws. The Exchange has
conditionally accepted the listing of such securities.

The net proceeds of the Offering will be used to fund, in part, Terra
Nova’s payment obligations under the Definitive Agreement.

The Common Shares of Terra Nova are currently halted but are expected to
resume trading once the Exchange issues its final bulletin in respect of these
matters.
