The rework/re-completion was completed on July 28, 2015 and production of oil and gas was established. On March 20, 2015, the Company sold a 37.5% working interest in the three wells. Jones County, Texas – Olson Lease - Palo Pinto Reef project During the fiscal year the Company acquired the Olson lease covering 160 acres in Jones County, Texas. This lease is 1.5 miles from the Strand Palo Pinto Reef Field which was discovered in 1940 and has produced 1,700,000 barrels of oil from 8 wells or 212,500 barrels of oil per well. The structure map on the Palo Pinto shows a large buildup in the Palo Pinto Reef across the southern portion of the lease. The Guinn #1 Olson well is 90’ high to a well 1000’ to the southeast and 42’ high to a well 1,150’ to the northwest. The Guinn well had a show and a tremendous buildup in the Palo Pinto Reef. The structural buildup and reef buildup across the acreage and close similarities to the Strand Field make this a very good prospect. Shackelford County, Texas – Guy Ranch Lease – Multiple Pay project During the fiscal year ended July 31, 2016 the Company acquired a 100% working interest in the 430-acre Guy Ranch Lease in Shackelford County. Subsequently the Company entered into a farm-out agreement with a third party whereby the third party has the right to earn a 75% working interest in a 20 acre drilling unit of the 430-acre lease. The third party is to pay 100% of the costs to drill and complete a well on the 20 acres to earn a 75% working interest. We are to be carried for 25% of the working interest in the first well. Winnemucca Mountain Gold Property, Nevada On September 14, 2012, the Company entered into an option agreement (as amended and restated on November 15, 2012, February 1, 2013 and August 26, 2013) with AHL Holdings Ltd., a Nevada corporation, and Golden Sands Exploration Inc., a company incorporated under the laws of British Columbia, Canada, wherein the Company acquired an option to purchase a revised 80% interest in and to certain mining claims from AHL Holdings and Golden Sands, which claims form the Swordfish Property (“Winnemucca Mountain Property”) in Humboldt County, Nevada. This Winnemucca Mountain property at September 14, 2012 consisted of 208 unpatented mining claims covering an area of approximately 3,800 acres. Effective July 30, 2014, the Company entered into amended and restated option agreement with AHL Holdings and Golden Sands that materially modifies and replaces the terms of the original option agreement (as amended last on August 26, 2013). The amended and restated option agreement dated July 30, 2014 was further amended by letter agreement on February 11, 2016. The aggregate cash fee payable to exercise the option was increased from $1,715,000 to $1,740,000 and the total number of common shares issuable to exercise the option has been increased from 100,000 to 3,850,000. Lastly, the amended and restated agreement provides that AHL Holdings may elect to receive shares of the Company’s common stock in lieu of any cash payments payable pursuant to the agreement at a 75% discount to the then current closing market price. In 2015 the Company failed to maintain in good standing all of the claims which form the Winnemucca Mountain Property whereby 70 unpatented mining claims were forfeited. The Company is obligated to pay the costs and cause to be re-acquired and recorded in the name of AHL Holdings the area of the property that was previously held by the 70 unpatented claims. No work was conducted on the property during the current fiscal year. The Company was given a default notice by the optionors on May 30, 2017, whereby the Company lost the right to earn an interest in the Winnemucca Mountain Property. At present the Company is in discussions with optionors to renegotiate the agreement.
