Yoho Resources Inc. Announces Results from Umbach Montney Unconventional Drilling

Calgary, Alberta - June 20, 2011 - Yoho Resources Inc. (“Yoho” or the “Company”) is pleased to
provide an update on its drilling and completion operations at Umbach/Nig Creek, British Columbia.

Umbach/Nig Creek, British Columbia

In March 2011, Yoho, with partner Progress Energy Resources Corp. (each 50% working interest) reentered
the a-A41-A/94-H-4 well and drilled a 1,050 meter horizontal section targeting the Montney
formation. In June 2011, the well was completed in the horizontal section with an 8 stage, 16
perforation completion using plug and perf completion methodology. The well was then flowed on
clean-up and production tested at various choke settings and flowing pressures over a 144 hour (6 day)
period. During the flow test, the well flowed up tubing at a stable rate of 4.2 Mmcf per day at 513 psi on
a 48/64” choke setting with 55 barrels per day of free condensate. The well was then flowed up casing
with a final rate of 6.3 Mmcf per day at a flowing pressure of 939 psi on a 38/64” choke setting, yielding
78 barrels per day of free condensate. The well is currently shut-in for pressure build-up. Liquids
production with the natural gas is expected to be 25 to 30 barrels per Mmcf with approximately 40-50%
of the liquids being condensate.

Yoho has accumulated 37,200 gross (19,300 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 Montney on the Company’s extensive land base in the area.

Kaybob, Alberta

Yoho continues to monitor production and pressure data from the two successful Duvernay horizontal
wells that the Company has a 33 1/3% working interest in (Yoho press releases September 14, 2010
and April 19, 2011). Core analysis data recently received from Yoho’s two vertical wells drilled in the
area targeting the Duvernay formation is currently being evaluated. Further development work in this
area on the Duvernay formation is currently being planned by Yoho subject to results of both the
production and the core data.

Mike/Pickel, British Columbia

The successful horizontal well (a-B21-I/94-H-3) drilled in January of 2011 (Yoho press release March
14, 2011) was on production up to June 15, 2011 when it was shut in due to the Spectra McMahon gas
plant turnaround. A preliminary development plan for this area has been prepared by the Company
and, given current natural gas pricing, development activities and capital allocation will be weighed
against results from both the Duvernay at Kaybob and the Montney at Umbach/Nig Creek.

Outlook

Yoho has recently had an increase in its bank credit facility to $40 million from $34 million.

Yoho is extremely pleased with the results to date of the three unconventional resource style projects
that were tested during fiscal 2011. The capital expenditures for the balance of fiscal 2011 are currently
being reviewed. Yoho will allocate “go forward” development capital for the balance of fiscal 2011 and
fiscal 2012 based on detailed economic analysis of all new data on all three unconventional projects.
