('ETPI'). The Nantawa Modification Agreement superseded the 'Nantawa Agreement' which had been which had been executed on November 19, 2009, and amended on February 4, 2010. Under the Nantawa Modification Agreement, Guinness received full vesting of a 49% interest in 128 full or fractional mineral claims/leases located in the Mount Nansen area of the Whitehorse Mining District of the Yukon Territory, Canada (the “Mineral Claims”). The other 51% interest in the Mineral Claims were retained by ETPI. The original Nantawa Agreement had been comprised of 175 mineral claims/leases. These were split between two packages: (i) a set of 47 mineral claims/leases referenced as the 'Tawa Claims'; and (ii) a set of 128 claims/leases referenced as the 'Mount Nansen Claims'. Guinness had contracted to purchase all 175 claims/leases from ETPI for total consideration of US$1,005,668 (comprised of: US$943,868 cash, in two parts, plus 60,000,000 restricted common shares of Guinness valued at US$0.00103 per share for a total share value of $61,800). During the period ended February 28, 2010, Guinness made payments of $471,934 and 60,000,000 restricted common shares to ETPI. A further cash payment of $471,934 was due by February 28, 2011 and during the period leading to this deadline, the Company projected it would not have the resources to fulfill the second payment on-time. Based on this, the Board determined it was in the best interests of the Company to negotiate revised purchase terms from ETPI for the Mineral Claims. To provide consideration to ETPI, the Company agreed to waive its rights under the Nantawa Agreement to the Tawa Claims, which had lapsed while in trust with ETPI. Under the revised agreement ETPI also agreed to have canceled 5,000,000 of the restricted common shares it had received under the Nantawa Agreement. The Nantawa Modification Agreement had the net effect of resolving the Tawa Claims matter between Guinness and ETPI and provided the Company an immediate vesting of a 49% interest in the remaining 128 claims/leases without requirement to make further payments to ETPI. Due to the elimination by ETPI on October 12, 2010 of the requirement for a payment to ETPI of $471,934 by February 28, 2011, our financial statements for the year ended May 31, 2011 include an entry to eliminate this liability. A corresponding non-cash 'Gain on cancelation of debt' income item of $471,934 was also recorded. During that period ETPI also submitted to the Company, and the Company has cancelled, 5,000,000 of the 60,000,000 restricted common shares previously issued to ETPI under the Nantawa Agreement. This cancellation was recorded through a reduction in Paid in Capital of $5,000. Ansell Agreement: On March 4, 2011, the Company executed an option agreement (the “Ansell Agreement”) with Ansell Capital Corp. (“Ansell”), ETPI and two individuals (the “Additional Parties”) to provide funding for the Charlotte Project (formerly named the “Nantawa Project”) in the Mount Nansen area of the Whitehorse Mining Division, of the Yukon Territory, Canada. Subject to the terms of the Ansell Agreement (incorporated herein by reference), Guinness, ETPI and the Additional Parties (collectively the “CSG Group”), agreed to grant Ansell an option to acquire up to an 85% undivided interest in the 128 mineral claims which form the Charlotte Project (formerly named the 'Nantawa Project') based on Ansell providing financing and expertise for development of the project. Under the Ansell Agreement, ETPI will hold the Charlotte Project claims (the “Properties”) in trust for all parties during the term of the Ansell Agreement. Upon Ansell earning an interest in the Properties, the parties have agreed to form a joint venture to further explore and develop the Properties, all upon and subject to the terms and conditions set out in the Ansell Agreement. Ansell is now the Operator of the project and will bear all project expenditures going forward.
