Yoho Announces Ongoing Unconventional Activity, Higher Production and Financial and Operating Results for the First 2011 Fiscal Quarter and Provides Operational Update

Calgary, Alberta - February 28, 2011 - Yoho Resources Inc. (“Yoho” or the “Company”) filed today
the interim unaudited consolidated financial statements for the three months ended December 31, 2010
and related Management’s Discussion and Analysis on www.sedar.com.

Highlights

  • Production for the three months ended December 31, 2010 was 2,505 boe per day, an increase
    of 12% from the 2,236 boe per day for the three months ended December 31, 2009. The
    increase in production is due to the tie-in of new wells from the successful drilling program.

  • Net exploration and development expenditures for the first three months of fiscal 2011 were $6.8
    million with 3 (1.8 net) wells drilled.

  • Generated funds from operations for Q1 2011 of $3.6 million ($0.10 per share diluted).

  • Closed equity issue in December 2010 for total gross proceeds of $10.0 million.

  • Maintained a flexible balance sheet with total net debt of $17.3 million at December 31, 2010 with
    a bank credit facility of $34 million.

Operations

During fiscal Q1, Yoho drilled three (1.8 net) wells resulting in one (1.0 net) gas well and two (0.8 net)
oil wells. These wells were placed on production during fiscal Q2, increasing Yoho’s current estimated
production to approximately 2,600 boe per day.

At Kaybob, Alberta, Yoho is currently participating in the drilling of two vertical wells and one horizontal
well targeting the Duvernay formation. At Mike, British Columbia, Yoho is drilling a horizontal well
targeting the Jean Marie formation. Field operations are ongoing on these four wells.

At Umbach, British Columbia, Yoho has recently completed a 48 section pooling agreement. Yoho now
holds a 52% working interest in 50 sections of Montney rights. The Company’s first well to test the
Montney formation will be a horizontal re-entry well and field operations on this well are expected to
begin during fiscal Q2.

Outlook

Yoho is currently planning a capital program for fiscal 2011 of between $28 and $29 million. With the
continued volatility in commodity prices, the activity levels for fiscal 2011 will be closely monitored and
adjusted based on cash flow levels. Yoho has also closed an equity financing in February 2011 for total
gross proceeds of $12 million. The amount currently drawn on the Company’s credit facilities is
approximately $1 million. Capital expenditures will also be adjusted subject to the results from several of Yoho’s larger unconventional projects.

Yoho will continue to move forward with the unconventional resource style projects that the Company
has been able to develop over the last 12 to 18 months. Yoho’s 2011 winter drilling program is
underway, with three wells (one horizontal and two vertical) currently being drilled that target the
Duvernay Shale and the drilling of the Jean Marie target at Mike/Pickell, British Columbia. A well
targeting the Montney at Umbach, British Columbia is scheduled to begin operations in fiscal Q2. The
Company has also been successful in the Kaybob area targeting high-liquids gas in the Cretaceous
section, utilizing both horizontal drilling and vertical wells. This program will also continue through fiscal
2011.
