pleased to provide the following update:

International Update - Hiring of Advisor and Curamhuele Block Extension

As announced in a press release dated June 11, 2013, the exploration period
for Madalena's 90% W.I. Curamhuele block was extended by way of an official
decree signed by the Province of Neuquén. This one year extension allows
Madalena until November 8, 2014 to satisfy the remaining work commitments of
approximately US $13.8 million plus VAT on the block providing the Company
enhanced financial flexibility.

The Company has retained RBC Capital Markets ("RBC") as its exclusive
financial advisor in connection with the Company's assets located within the
Neuquén Basin of Argentina. The Company's intention is to identify a potential
joint venture partner(s) to accelerate exploration and development activities
on the Curamhuele block where the Company has exposure to over 1.5 billion boe
(65% oil) of best estimate contingent plus prospective recoverable resources
as estimated by a recent Ryder Scott evaluation. The details of the Ryder
Scott evaluation were disclosed in the Company's press release dated April 30,
2013.

Corporate Update - Increase in Credit Facilities

The Company is also pleased to announce increases to its credit facilities
with the National Bank of Canada. The revolving operating demand loan and the
acquisition / development demand loan have been increased from $4.75 million
to $10.0 million and from $1.25 million to $3.0 million, respectively. The
credit facilities are subject to a periodic review by the bank, with the next
review scheduled on or before September 1, 2013. The facilities are currently
unutilized.

Reserves and Other Oil and Gas Disclosure

All calculations converting natural gas to barrels of oil equivalent ("boe")
have been made using a conversion ratio of six thousand cubic feet (six "Mcf")
of natural gas to one barrel of oil, unless otherwise stated. The use of boe
may be misleading, particularly if used in isolation, as the conversion ratio
of six Mcf of natural gas to one barrel of oil is based on an energy
equivalency conversion method primarily applicable at the burner tip and does
not represent a value equivalency at the wellhead. Given that the value ratio
based on the current price of crude oil as compared to natural gas is
significantly different from the energy equivalency of 6:1, utilizing a
conversion on a 6:1 basis may be misleading as an indication of value.

In addition, the following sets out the applicable definition for each of the
resource categories as set out in the COGE Handbook, which is referred to in
this news release and the Company's April 30, 2013 news release.
