Gibellini Project consists of the Gibellini, Louie Hill and Bisoni–McKay vanadium deposits. The Project would consist of constructing and operating an open pit mining operation and heap leach process facility to extract and recover vanadium and uranium.
On September 11, 2023, Nevada Vanadium Mining reports the release of the report of the Final Environmental Impact Statemen (EIS) for the Gibellini Vanadium project. The final step in the Federal permitting process for Gibellini is the issuance of the Record of Decision ("ROD") by the BLM. |

Nevada Vanadium Mining Corp (NVMC) holds a 100% interest in the Gibellini Project through mineral lease agreements and staked claims. Claims are in the name of NVMC’s wholly-owned Nevada subsidiary, Nevada Vanadium LLC (Nevada Vanadium) (formerly Vanadium Gibellini Company LLC (Vanadium Gibellini)).
As of March 31, 2023, the Silver Elephant held an approximate 40% interest in Oracle which held an approximate 41% interest in Nevada Vanadium, as well as a direct interest in Nevada Vanadium of approximately 5%.

Summary:
The Project Gibellini consists of the Gibellini, Louie Hill and Bisoni–McKay vanadium deposits.
DEPOSIT TYPES
The vanadium deposits that occur on the Property are examples of the “USGS Shale-Hosted Vanadium” deposit type of Kelley et al. (2017). Vanadium-rich metalliferous black shales occur primarily in late Proterozoic and Phanerozoic marine successions. The term shale is used broadly to include a range of carbonaceous rocks that include marls and mudstones. These fine-grained sedimentary rocks were deposited in inland seas and on continental margins. They typically contain high concentrations of organic matter, reduced sulfur, and a suite of metals including copper, molybdenum, nickel, platinum group elements (PGEs), silver, uranium, vanadium, and zinc.
The vanadium mineralization of the Gibellini, Louie Hill, and Bisoni–McKay areas is hosted in sedimentary rocks. Oxidation of the primary organic and reduced sulfide material in portions of the deposit resulted in the presence of secondary vanadium oxide minerals. The depth and intensity of oxidation is variable across the deposits and accounts for the three primary stratiform facies recognized on the project: oxide, transitional, and reduced. Mineralization is tabular, conformable with bedding, and remarkably continuous in grade and thickness between drill holes.
The mineralization at the Gibellini manganese–nickel mine forms a pipe-like structure hosted in limestone, is primarily en ........
Summary:
The Project consists of the Gibellini, Louie Hill and Bisoni–McKay vanadium deposits.
Based on the geometry and the depth of both Gibellini and Louie Hill deposits, surface mining methods are considered most economically amenable.
Open pit mining optimization inputs for the Project are based on an open pit bulk mining method. Contract mining is assumed for a contractor using a small equipment fleet.
Five pit phases were developed for the Project. Phases I, II and III are mined from the Gibellini deposit and Phases IV and Phase V are mined from the Louie Hill deposit. The Gibellini pit will be mined first in its entirety based on the confidence categories of the resource estimate, and the preliminary nature of the Louie Hill pit, as opposed to having the pits based on optimized grade.
The phases were selected from the different resulting pit optimization shells and based on operational parameters such as bench advance and pushback widths.
Mining at the Gibellini pit will start at elevation 7120 ft on the northernmost area of the deposit and mining in the Louie Hill pit will start at elevation 7220 ft. The deepest bench of Gibellini will be at elevation 6740 ft to remain above the local water table and facilitate pit drainage. At Louie Hill, the deepest bench to be mined will be at elevation 6920 ft.
Two waste rock storage facilities (WRSFs) were designed for a total capacity of 4.1 Mst. Only non acid generati ........
