Yoho Resources Inc. Updates Unconventional Activity and Announces Financial and Operating Results for the Second 2011 Fiscal Quarter

Calgary, Alberta - May 25, 2011 - Yoho Resources Inc. (“Yoho” or the “Company”) filed today the
interim unaudited consolidated financial statements for the six months ended March 31, 2011 and
related Management’s Discussion and Analysis on www.sedar.com.

Highlights

  • Production for the three months ended March 31, 2011 was 2,472 boe per day. Production for
    the quarter was impacted by disruptions at third-party processing facilities. Yoho’s current
    estimated production is approximately 2,850 boe per day with the alleviation of recent production
    interruptions caused by the recent forest fires in the Kaybob area.
  • Net exploration and development expenditures for the first six months of fiscal 2011 were $23.4
    million.
  • Generated funds from operations for fiscal Q2 2011 of $3.4 million ($0.09 per share diluted).
  • Closed an equity issue in February 2011 for total gross proceeds of $12.0 million.
  • Maintained a flexible balance sheet with total net debt of $18.5 million at March 31, 2011 with a
    bank credit facility of $34 million.

Operations

During fiscal Q2, Yoho continued to move forward with the three unconventional resource style projects
that the Company has been able to develop over the last 12 to 18 months.

Kaybob, Alberta

During fiscal Q2, Yoho participated at a one-third working interest in the drilling and completion
operations for the second horizontal well targeting the Devonian Duvernay shale formation. The well
(the “3-13 well”) was drilled to a bottom hole location at 03-13-060-20W5 and completed using a 12
stage “plug and perf” horizontal completion technique, incorporating perforation clusters (2 and 3 per
stage) to stimulate the well. The 3-13 well was placed on production during April 2011 at several
restricted rates to determine a variety of reservoir parameters at different flowing conditions. Also
during April 2011, the first horizontal Duvernay well (the “15-33 well”), which was drilled in fall 2010,
was placed on production at initial rates exceeding 500 boe per day with very high associated liquids
production. The natural gas liquids content of the 15-33 well is similar to the 3-13 well and both exceed
original expectations for liquid-to-gas ratios.

The Company also participated in two vertical wells targeting the Duvernay shale as part of farm-in
agreements to earn working interests in additional land. The first vertical well (26.0%) was drilled,
cored, logged and cased with 7 inch casing which would allow the drilling of a horizontal section at a
later date. The second vertical well (50%) was drilled, cored, logged and completed to determine both
the liquids content of the gas and the reservoir pressure in that geographic location.

Yoho is extremely encouraged by the production results from both of the horizontal Duvernay shale
wells, particularly the high liquids content associated with the natural gas given the current premium in
pricing for natural gas liquids. Production from the two Duvernay horizontal wells will be monitored and
Yoho will review additional drilling locations with its partners. 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.

Mike, British Columbia

During fiscal Q2, Yoho drilled the a-B21-I/94-H-3 well targeting the Jean Marie formation. It was
completed in the open hole section with a nitrified acid stimulation. The well is was tied-in and place on
production during April 2011 at an initial stable rate of 3.0 Mmcf per day. Yoho has accumulated
22,000 net acres of land adjacent to this well. The successful application of horizontal technology in
this tight gas formation will now allow Yoho to establish a comprehensive development plan for the
Jean Marie on the Company’s extensive land base in the area.

Umbach, British Columbia

Yoho’s first well to test the Montney formation at Umbach was a horizontal re-entry well. A 1,050 metre
horizontal section was drilled during Q2 with excellent penetration rates and substantial mud gas shows
through the entire horizontal section. The well will be completed using a multi-stage “plug and perf”
horizontal completion technique. Completion operations are expected to begin before the end of May
2011. Yoho currently holds a 50% working interest in 52 sections of land at Umbach.

Outlook

Yoho is extremely pleased with the results to date of the unconventional resource style projects that
were tested during fiscal Q2. The Company will continue to monitor production from both the Mike
Jean Marie well and from both horizontal Duvernay wells and will await the results of the completion of
the Umbach well to determine capital expenditures for the balance of fiscal 2011. These results will
also build the basis for the Company’s fiscal 2012 business plan.
