The Apache Prospect 4 of 18

THE APACHE PROSPECT HISTORICAL PERSPECTIVE The Permian Basin is a rich oil and gas producing region located in West Texas and Southeastern New Mexico. Three hundred million years ago, The Permian Sea covered the vast expanse of this region and in the wake of the largest mass extinction in Earth’s history, left gigantic reservoirs of oil in one of the thickest deposits of Permian rocks found anywhere in the world.

Formally home to the Apache Nations, among the strongest and fiercest tribes of the Plains Indians, the first commercial oil well in the Permian Basin was completed in 1921, about 20 miles from Sterling County, Texas and the site of Goldstone Energy’s oil and gas lease, appropriately named, The Apache Prospect. During its peak, drilling in this region resulted in lines of oilfields, some stretching as muchas 200 miles long and 35 miles wide. Over the past 100 years, the Permian Basin has produced 30 billion barrels of oil and 75 trillion cubic feet of natural gas. Industry experts have long estimated that the recoverable oil and natural resources still in the ground will exceed what has already been produced over the past 90 years using modern recovery technologies. Their assertion proved true when late last year the most prolific oil discovery since the Anwar Oil Field in Saudi Arabia was found in the Basin, making it the second largest oil reserve in the world.

The Apache Prospect 5 of 18

CURRENT VIEWPOINT As reported by Bloomberg News on Nov. 15th, 2016, “One portion of the giant field, known as the Wolfcamp formation, was found to hold 20 billion barrels of oil trapped in four layers of shale beneath West Texas. That’s almost three times larger than North Dakota’s Bakken play and the single largest U.S. unconventional crude accumulation ever assessed, according to the U.S. Geological Survey. At currentprices, that oil is worth almost $900 billion.

The estimate lends credence to the assertion from Pioneer Natural Resources CEO Scott Sheffield that the “Permian’s shale could hold as much as 75 billion barrels, making it second only to Saudi Arabia’s Ghawar field.”

Oil explorers have been flocking to the Permian Basin in West Texas and New Mexico to tap deposits so rich that they can generate profits even at lower oil prices. A race to grab land in the Permian has been the main driver of a surge of deals in the energy patch and the industry’s main source of good news in an otherwise, somewhat stagnant market.

Although the Permian has been gushing crude since the 1920s, its multiple layers of oil-soaked shale remained largely untapped until the last several years, when intensive drilling and fracturing techniques perfected in other U.S. regions were adopted. The Wolfcamp, which is as much as a mile thick in some places, has been one of the primary targets. The Apache Prospect rests in the heart of this region.

“

The fact that this is the largest assessment of continuous oil we have ever done just goes to show that, even in areas that have produced billions of barrels of oil, there is still the potential to find billions more.

Walter Guidroz, Coordinator for the Geological Survey’s Energy Resources Program

THE DETAILS Our newest project in this area, the Apache Prospect, sits just north of our previous project, the 320-acre Comanche Prospect on the N. Sellers Lease in Sterling County, Texas. Management has had extensive previous recovery experience in this area with production in the Albaugh, Triple M and Credo Limestone Zones in the Wolfcamp formation and is very excited at its continued growth in the Permian Basin.

The property is on known oil production ground and its proven undeveloped site is ready for drill and test. We will be able to use the salt water disposal installed on our adjacent property, the Comanche Prospect, thereby keeping waste water disposal costs at a minimum and much of the production infrastructure is already laid or nearby.

Goldstone Energy’s operator and partner in this project is Ampak OilCompany, which has been operating since 1988 and is the same operator that brought the Comanche Prospect online earlier in the year. Their experience in drilling, completing, equipping, producing and operating

both vertical, directional, and horizontal oil and gas wells in the Basin is extensive.

Ampak currently operates many oil and gas wells throughout the Permian, including the Comanche Prospect, and is led by M.G. Khan, who has a Master of Science degree in Petroleum Engineering from the University of Oklahoma and over 35 years’ experience in supervising and managing oil and gas operations. Mr. Khan has laid out an action plan that will rapidly and efficiently bring the Apache Prospect into production. This project makes sense and has a high probability of success.

// ACTION PLAN Their plan calls for the drilling of a new well to a depth of 8,700’. The primary targets will be the Upper and Lower Wolfcamp Formation where a multi-stage fracking will occur and secondary targets would include a conventional completion in the Mississippian Oil Zone among others. Current data suggests that this site could produce in the range of 200-400 BOPD (barrels of oil per day) and could include commercially viable quantities of natural gas.

AMPAK OIL COMPANY Ampak Oil Company has been a licensed oil and gas operator in the state of Texas (Operator #020463) since its founding in 1988. During the last 27 years, Ampak Oil has drilled, acquired, or participated inwells in many areas around the state. Wells in the Permian Basin, the Bend Arch, South Texas, the Hardeman Basin in North Texas, and along the Texas Gulf Coast have resulted in production in excess of 1 million barrels of oil to-date. That number continues to increase as new successful wells are completed.

KEY MANAGEMENT M.G. Khan

Ross Townsley

Mr. M.G. Khan, 62, is President of Ampak Oil Company and has been since its inception in 1988. Mr. Khan holds a Master’s Degree in Petroleum Engineering from the University of Oklahoma. Since enteringthe oil business in the early 80’s, Mr. Khan has supervised operations in over 700 wells. Mr. Khan has been an active member of the Society of Petroleum Engineers of AIME since 1978.

Mr. Townsley, 58, entered the oil and gas industry in 1981 with an MBA from the Ohio State University with dual majors in International Business and Logistics.

He advanced through the Land Managementdepartment with Sun Exploration and Production Co. (Sunoco) until 1988. Mr. Townsley joined Ampak Oil Company at the beginning of 1990 as Director of Land Management.

GEOLOGICAL SUMMARY THE APACHE PROSPECT: AMPAK OIL COMPANY The Comanche Prospect is in northwest Sterling County, approximately 30 miles southeast of Big Spring, Texas. Most of the wells within the field were drilled to the base of the Wolfcamp and the majority of production has come from the Middle Wolfcamp carbonate.

The plan is to drill one new well (The Apache 1) to a depth of around 8,700’. The well will be completed by employing the multi-stage fracking technique. The completion will involve fracking the target zones with high-rate pumping, one-zone-at-a-time beginning with the deepest zone.

The prospect area offers significant potential for additional developmental drilling opportunities. Based on published reports from larger oil companies and using the basic oil-in-place formula, 8-12million barrels of recoverable oil is estimated to be in place per 640-acre section in the Apache Prospect area.

To summarize: The Comanche Prospect is located within a proven oil field and in an area were oil companies have large blocks of land under lease with the mindset of owning reserves in the ground. The presence of multiple oil-bearing zones, comprised of over 2,000’ of tight oil strata, offers a tremendous opportunity to develop significant, long-lasting oil production. The proposed developmental drilling plan should result in oil production which will provide cash flow for many years to come.

TAX ADVANTAGES There are extremely generous tax benefits available to oil and natural gas investors.

Such benefits include the deduction for Intangible Drilling Costs (”IDCs”), depreciation deductions with respect to Tangible Drilling and Completion Costs (“TDC’s”), amortization deductions with respect to Geological and geophysical Costs (G&G Costs) and depletion, if applicable.

TAX BENEFITS

DEPLETION ALLOWANCE

Investing in oil and gas can be one of the most tax-advantageous investments available today.

Congressional incentives encourage domestic petroleum development. Oil and natural gas from domestic reserves helps to make our country more energy self-sufficient by reducing our dependence on foreign sources. Congress has provided tax incentives to stimulate domestic oil and natural production financed by private sources. Drilling projects offer many tax advantages that were placed in the Tax Code by Congress. At the end of each calendar year, Aimco, LLC will provide you with a schedule K1 for your working interests(s).

The current depletion allowance is 15% of your share of the gross income from the property based on average daily production and can be taken every year until the well plays out. This makes fifteen cents of every gross income dollar non-taxable, thereby producing tax-sheltered income.

ACTIVE VS. PASSIVE INCOME The Tax Reform Act of 1986 introduced into to the Internal Revenue Code the concepts of “passive” income and “active” income.

The Act prohibits the offsetting of losses from passive activities against the income from active businesses. The Tax Code specifically states that a Working Interest in an oil and natural gas well (including an investment made through a general partnership interest in a limited partnership) is not a “passive” activity; therefore, deductions can be offset against income from active stock trades, business income and salaries. Limited partners in a partnership owning working interests, however, are only deemed to be passive investors and may only deduct passive losses against passive income.

SMALL PRODUCERS TAX EXEMPT Small Producers Tax Exemption: The 1990 Tax Act provided one special tax advantages for companies and individuals. This tax incentive, known as the “Percentage Depletion Allowance”, is specifically intended to encourage Participation in oil and gas drilling.

This tax benefits is not available to large oil companies, retail petroleum marketers, or refiners that process more than 50,000 barrels per day. It is also not available for entities owning more than 1,000 barrels of oil (or 6,000,000 cubic feet of gas) average daily production. The “Small Producers Exemption” allows 15% of the Gross Income (not Net Income) from an oil and gas producing property to be tax-free.

INTANGIBLE DRILLING COST (IDCS) Intangible Drilling Costs (IDCS): IDC’s can include labor intensive costs such as the drilling contractor and professional services, and are reported to the investor at the end of

the year. For a producing well, up to 85% of the investment constitutes what are known as IDC’s and are written off an investor’s ordinary income in the first year. Typically, most of the investment is deductible in the same tax year and can be offset against active or ordinary income (salaries, business income, stock trades, etc.). For every dollar of IDC invested, the investor receives one dollar of deduction.

These IDC deductions reduce an investor’s dollars at risk. IDC’s can make up roughly 85% of the total investment. By way of illustration, an investment of $100,000 made in an oil and gas partnership could yield up to $85,000 in tax deductions for the year the investment is made. For an investor in a 35% tax bracket, that could mean actual tax savings of up to $29,750 in the first year.

TANGIBLE DRILLING COST (TDCS) Tangible Drilling Costs (TDCS): TDC’s can include pipe, storage tanks, along with wellhead equipment which are then capitalized and depreciated. For a producing well, approximately 15%-30% of your investment constitutes TDCs, which are depreciated over a seven-year period using the Accelerated Cost Recovery System (ACRS).

LEASE COSTS Lease Costs: Leasehold costs (purchase of leases, minerals, etc.), legal expenses for title opinions, etc., administrative, accounting, and lease/well operating costs (LOC) are also 100% tax deductible through cost depletion.
