The Company, through its wholly-owned subsidiaries, Contango Minerals and AGT, owns the mineral rights to approximately 223,200 acres of State of Alaska unpatented mining claims for gold ore exploration, and the Peak Gold JV holds approximately 13,000 acres of State of Alaska unpatented mining claims in addition to the Tetlin Lease (described below). Unpatented mining claims are unique property interests in that they are subject to the paramount title of the State of Alaska and the rights of third parties to the use of the surface within their boundaries, and are generally considered to be subject to greater title risk than other real property interests. The rights to deposits of minerals lying within the boundaries of the unpatented state claims are subject to Alaska Statues 38.05.185 - 38.05.280, and are governed by Alaska Administrative Code 11 AAC 86.100 - 86.600. The validity of all State of Alaska unpatented mining claims is dependent upon inherent uncertainties and conditions.
The Peak Gold JV leases approximately 675,000 acres for exploration and development pursuant to the Tetlin Lease with the Tetlin Tribal Council. The Company retained title lawyers to conduct a preliminary examination of title to the mineral interest prior to executing the Tetlin Lease. The Peak Gold JV conducted a title examination prior to the assignment of the Tetlin Lease to the Peak Gold JV and performed certain curative title work. In addition, in connection with the assignment of the Tetlin Lease from the Company to the Peak Gold JV, the Company and the Native Village of Tetlin entered into an Estoppel and Agreement and a Stability Agreement, which were approved by the Tetlin Tribal Council and the Native Village of Tetlin members and renewed on September 29, 2020 in connection with the CORE Transactions described in "Item 2 Property Summary" (the "Tetlin Agreements"). The Tetlin Agreements approved the assignment of the Tetlin Lease to the Peak Gold JV and, among other things, confirmed the validity and effectiveness of the Tetlin Lease.
We cannot provide assurance that title to our properties will not be challenged. We or the Peak Gold JV, as applicable, may not have, or may not be able to obtain, all necessary surface rights to develop a property. Title insurance is generally not available for mineral properties and our and the Peak Gold JV's ability to ensure that we or the Peak Gold JV, as applicable, have obtained a secure claim to individual mining properties may be severely constrained. Our and the Peak Gold JV's mineral properties may be subject to prior unregistered agreements, transfers or claims, and title may be affected by, among other things, undetected defects. In addition, our ability to continue to explore and develop the property may be subject to agreements with other third parties including agreements with native corporations and first nations groups.
A deficiency in title or claims by a third party may not be curable. It does happen, from time to time, that the title to a property is defective, having been obtained in error from a person who is not the rightful owner of the mineral interest desired. In these circumstances, the Company or the Peak Gold JV, as applicable, might not be able to proceed with exploration of its properties or might incur costs to remedy a defect. This could result in our not being compensated for our prior expenditures relating to the property. It might also happen, from time to time, that the Company or the Peak Gold JV might elect to proceed with mining work despite any such deficiency or claim.
