OPERATIONAL UPDATE FOR THE QUARTER ENDED 30 JUNE 2011 LETTER TO SHAREHOLDERS FROM THE CHIEF OPERATING OFFICER

Dear Shareholders, 115 Days – that’s the number of days Antares Energy has been “in” the Permian Basin. In those 115 days Antares has amassed an acreage position exceeding 28,500 net acres divided amongst three project areas: Southern Star, Big Star and Northern Star. In those project areas we have drilled or are drilling 10 wells and have fracture stimulated six wells. While it is still very early in these projects there is cause for encouragement and even a bit of excitement. At Southern Star, the Lonestar No. 1 well continues to clean-up while already exceeding 100 boepd with the expectation of achieving “type-curve” results. The Cottonwood No. 1 and Smith No. 1 have been fracture stimulated and are just now coming online. The Ray No. 3 and Smith No. 2 will be fracture stimulated third quarter and will add to our growing production base. The addition of these five wells will bring the gross production from the Southern Star project to near, if not over, 1,000 boepd – a near term milestone. Production prior to the addition of these new wells was approximately 700 gross boepd. More detailed production information will be available after the final adjustment settlement of the Southern Star project, scheduled for the 5th August 2011. Going forward; surveyors have been sent out to the field to stake our next five drilling locations. There is a balance to strike in selecting locations. Firstly, given the proven nature of the asset, drilling those wells located on leases with the highest net revenue interest (NRI) is paramount. This maximizes project net present value, the ultimate objective of any commercial endeavor. Secondly, locating wells adjacent to those wells that are believed to exceed “type-curve” performance. This was the impetus in selecting the Ray No. 3 and Smith No. 2 locations. The Ray No. 3 is adjacent to an exceptional well being operated by Linn Energy and the Smith No. 2 is a direct offset to the Smith No. 1, we recently drilled and fracture stimulated. In that well oil flowed to surface while drilling through an objective reservoir – always a good sign. Thirdly, locating wells in those leases still requiring production to hold the lease. Currently 15 wells are needed to hold the entire position. A final note of interest regarding Southern Star is that only a handful of the existing 24 wells were completed with current stimulation technology and techniques. This has led Antares to rework several wells and plan for the fracture stimulation of others. For example, the Thomas No. 1 was not fracture stimulated and was only completed through several perforations and acid placed over those perforations. That same well drilled and completed today would be subject to a 10-stage fracture stimulation with over 1,000,000 pounds of proppant placed. This type of low hanging fruit has been catalogued and is currently being addressed. While Southern Star is currently our reserve and production foundation it currently represents less than 12% of our net acreage position. Our largest position in the Permian resides at Big Star where we are now in possession of over 13,000 net acres. We have been so encouraged with this position that it has rapidly expanded from 4,500 net acres on April 27th to its current size. That encouragement is now beginning to be

realized. Three wells have been drilled with a fourth currently drilling. Two wells have been fracture stimulated with the remaining two to be frac’d in August. The first of the frac’d wells, the Stuart 12 No. 1, has only been online for approximately 14 days with commercial quantities of oil and gas flowing. As the well continues to clean up these rates will further increase. It should be noted no reserves have been assigned to the Big Star project area; however, 3P reserve potential assuming a range of estimated ultimate recoveries (EURs) of 125 Mboe and 175 Mboe could yield between 30 Mmboe and 43 Mmboe of net, after-royalty reserves on 40 acre spacing. There have also been some growing pains and learning curves to surmount with our entry into the Permian Basin. Our first fracture stimulation in the Northern Star project area has not gone as we envisaged. After a month of production data from the Newbrough No. 1 it is apparent we have communicated with a shallow, water-bearing zone. However, we are confident we have a commercial well due to the flow of hydrocarbons into the wellbore from deeper zones prior to the fracture stimulation of the shallower zones. So what do we do now? We learn. We will set a retrievable bridge plug to isolate the shallow water-bearing zone from the deep hydrocarbon-bearing zone. We will then pump as much fluid off the formation to determine when/if the water cut decreases and oil cut increases. If not, we will pump cement into the perforations, retrieve the bridge plug and begin producing from the deeper hydrocarbon-bearing zone. On our next fracture stimulation at Northern Star, Cozart “A” No. 1 well, we will avoid this zone. The above aside, there is certainly industry excitement surrounding the Northern Star project area. Geologically, this area is located in a depositional low meaning the potential reservoir section is thicker. Petrophysical log analysis confirms this with some of the highest oil and gas in place numbers we’ve seen in the Basin. Industry is realizing this as well, and permitting and drilling activity in our immediate area is at a brisk pace. As a result of the expanded section there are numerous oil and gas bearing zones over thousands of feet. We admiringly call this a vertical horizontal, meaning we are essentially encountering the same amount of gross reservoir one would encounter in a horizontal well but doing it for approximately 1/5 of the cost in a vertical well. In the attached quarterly presentation we attempt to visualize this concept with images you may find familiar. In conclusion, I want to thank all shareholders for their loyalty and patience as we endeavor to build a company we will all be proud of. While there is reason for excitement, there is also much work ahead. Know that we are working hard to make this a reality. Very truly yours,

Matt Gentry Director & Chief Operating Officer

Why the Permian Basin?

Quarterly Presentation, 25 July 2011 Slide 7

“Best place to find oil is in an oilfield!” Permian Basin has been producing commercial oil since 1921 (90+ years). United States Geological Survey (USGS) estimates 95.4 BBO Original Oil In Place for Permian reservoirs (34+ main conventional play types). Over 33.7 BBO of reserves produced (35% of OOIP from 1,340+ fields). Currently producing 420,000 BOPD (44% of Texas’ 960,000 BOPD output). Permian experiencing significant activity in oil rich unconventional plays (300+ wells). Principal oil targets – Wolfberry (Wolfcamp & Spraberry), Missberry (Mississippian & Wolfberry), & Wolffork (Wolfberry & Clearfork). Investment drivers :

1.Full vertical completion costs of approx. $2.0 MM USD (accessing approximately 4,000+’ of pays) vs. horizontal shale completions of up to $10 MM USD.

2.Attractive finding & development (F&D) costs – assuming 150 Mboe/well & $2 MM USD completed well cost = F&D cost of $13.3/boe.

3.Better access to services (drilling rigs, fracture stimulations, and sales infrastructure) in the proven Permian Basin as compared to new resource play areas.

4.Significant and liquid deal opportunities for Antares providing the ability to grow oil portfolio.

Key Aspects Continual rig count growth (Currently 200+ rigs active). Drilling Permits at historic high. Play expanding from western concentration to east and north. Higher IP’s and EUR’s in previously underexploited areas. Completion “recipes” being improved in latest wells. Good, expanding oil and gas infrastructure in place.

$1.5-2.5 MM USD vertical well costs to exploit multi thousand feet hydrocarbon column unique in resource plays.

Wolfberry covers over 6,000 sq. mi. Reserve accreditors accepting larger proved areas and de-

risking 40 acre reserves. Deeper reserves potential and 20 acre spacing exploitation is

accelerating and inevitable.

Quarterly Presentation, 25 July 2011 Slide 13

After the well is drilled, mudlogs and wireline logs are evaluated. A perforation schedule is devised to access the oil and gas in place in

each of the prospective reservoirs. Working with the fracture stimulation companies, an optimal treatment

procedure is created to allow the oil and gas in each reservoir to access the recently completed wellbore.

Typical fracture treatment is between 8 and 12 stages, and lasts 2-3 days. Total treatment cost is approximately $600,000.

320 Pumping Unit at the Southern Star project area

Typical tank battery at the Southern Star project area

After the fracture stimulation, the well will go through a period of “clean-up” where the water used to fracture stimulate the well (e.g. the load) is recovered.

During clean-up, oil production gradually increases until it reaches its peak initial production rate. This can take as long as a 1-3 months.

Peak initial production rates will typically range between 75 – 150 boepd.

Our experience demonstrates mobilizing a pumping unit (320 pumping unit or 467 pumping unit) immediately onto location saves time and money. A well can immediately be put on pump when natural flow subsides.

Initial tank battery consists of two 500 barrel oil tanks and one 200-500 barrel water tank. The batteries are modular to allow for additional tanks as more wells are brought online.

Why 20 Acre Downspacing Is Inevitable

Quarterly Presentation, 25 July 2011 Slide 25

Spraberry Reservoirs Petrophysical Character

Wolfcamp Reservoirs Petrophysical Character

Wolfberry is currently being developed on 40-acre spacing. Large Operators (i.e. Pioneer) are undertaking 20-acre down-

spacing to maximize reservoir recoveries. Pioneer drilled 45, 20-acre wells in 2008 through 2010 with plans

to drill 20 more in 2011 following Field Rules applications. Original Oil in Place (OOIP) of 150-250 MMBO/section (640 Acres) Current Wolfberry per well EUR’s imply < 3% recovery of OOIP Spraberry = 60-100 MBOE Wolfcamp = 100-130 MBOE
