Yoho Resources Inc. Announces Financial and Operating Results for the Third 2011 Fiscal Quarter Initial Production from Duvernay Wells Increases Netbacks; Horizontal Wells Targeting Duvernay and Montney Budgeted for Fiscal 2012

Calgary, Alberta - August 24, 2011 - Yoho Resources Inc. (“Yoho” or the “Company”) filed today the
interim unaudited consolidated financial statements for the nine months ended June 30, 2011 and
related Management’s Discussion and Analysis on www.sedar.com.

Highlights

  • Production for the three months ended June 30, 2011 was 2,500 boe per day. Production for the
    quarter was impacted by the turnaround at the McMahon Gas Plant in British Columbia and forest
    fires and extensive flooding in the Kaybob area of Alberta.
  • The first two successful Duvernay horizontal wells in Kaybob, Alberta were placed on production
    during fiscal Q3. The high level of associated liquids production from these wells contributed to a
    $20.16 per boe operating netback for fiscal Q3, a 15% increase from $17.56 per boe in fiscal Q2
    2011.
  • Net exploration and development expenditures for the first nine months of fiscal 2011 were $28.1
    million.
  • Generated funds from operations for fiscal Q3 2011 of $4.1 million ($0.10 per share diluted).
    • Maintained a flexible balance sheet with total net debt of $20.0 million at June 30, 2011. During
    Q3 the bank credit facility was increased to $40 million.

Operations

During fiscal Q3, Yoho continued to move forward with the three unconventional resource projects that
the Company has been developing.

Kaybob, Alberta

During fiscal Q3, the first two successful horizontal wells targeting the Duvernay formation were placed
on production. Yoho has a 33 1/3% working interest in these wells and continues to be encouraged by
the production results. In particular, the natural gas liquids content of both wells exceeds the original
expectations for liquid-to-gas ratios, with condensate and pentanes comprising approximately 61% of
the natural gas liquids. Yoho currently has working interests in 50.5 gross (17.7 net) sections of land
with Duvernay rights in the Kaybob area along this liquids rich trend. Near term development plans
include drilling six wells and ultimate development spacing expected to be 6 to 8 wells per section.

Umbach, British Columbia

During fiscal Q3, Yoho completed its first horizontal well to test the Montney formation at Umbach. The
a-A41-A/94-H-4 well was flowed (on test) up casing at 6.3 Mmcf per day. Liquids production with the
natural gas is expected to be 30 barrels per Mmcf with approximately 40-50% of the liquids being
condensate. Tie-in operations for this well are currently underway. Yoho has accumulated 38,610
gross (20,005 net) acres of land on this Montney play. A second horizontal well is currently drilling with
plans for a total of five wells in 2012. Ultimate development well density is expected to be 4 wells per
section.

Mike, British Columbia

During fiscal Q3, the a-B21-I/94-H-3 well targeting the Jean Marie formation was tied-in and placed on
production at an initial stable rate of 3.0 Mmcf per day. Yoho has accumulated 22,000 net acres of land
adjacent to this well. Although this successful horizontal well, along with the two existing vertical wells,
delineates a substantial development project for the Company, this area cannot currently compete for
capital allocation by the Company relative to Yoho’s liquids rich Duvernay and Montney plays. Further
development of the Jean Marie will be dependent upon natural gas pricing.

Outlook

The successful drilling in 2011 of these three unconventional projects delineates a drilling inventory that
may have in excess of 250 locations under full development. The Company’s ongoing exploration and
development plan will focus on the Duvernay and Montney plays due to the high rate of natural gas
liquids associated with the gas. Yoho’s Board of Directors has approved the fiscal 2012 capital budget
which has been set at $35 to $40 million and includes the drilling of six horizontal Duvernay wells at
Kaybob, five horizontal Montney wells at Umbach and the construction of a Yoho operated 25 Mmcf per
day compressor station at Umbach. Production for fiscal 2012 is budgeted to average between 3,200
and 3,300 boe per day with exit production of between 3,700 and 3,800 boe per day. The fiscal 2012
capital program is expected to generate funds from operations of $22 to $24 million based on a natural
gas price of $3.75 per GJ at AECO and an oil price of $90.00 per barrel at Edmonton. Both natural gas
and oil prices have been adjusted in the budget for Yoho’s relative quality to posted prices. The
Company expects to fund the fiscal 2012 capital program with a combination of cash flow and the
Company’s credit facilities. With the continued volatility in commodity prices, the activity levels for fiscal
2012 will be monitored to match capital expenditures with expected cash flow and available credit lines.
