Australian mineral resources company Anson Resources, which has assets in the United States, has submitted a Plan of Operation (POO) to begin a drilling program at its Green River Lithium project in southeastern Utah.
He said in a press release on Tuesday that the OOP has been submitted to the Department of the Interior, Bureau of Land Management, while a Notice of Intent (NOI) has been submitted to the Division of Oil, Gas and Utah Mining (UDOGM), Minerals. division Additionally, an application permit to drill has been submitted to UDOGM because of the well depths, Anson said.
East of the Green River, amid plateaus surrounded by canyons and ridges, is a proposed well. These uplands are intersected by ephemeral drainages, which generally flow west to the Green River. According to Anson, the Mt Fuel-Skyline Geyser well platform is located in the core region of the Green River project claims.
Anson Resources said the first stage of the exploration program is to re-enter the Mt Fuel-Skyine Geyser 1-25 well, which was drilled to a total depth of 9,508 feet. The well terminated in Mississippi units after crossing the zone at 9,157 feet. Both the clastic zones and the Mississippian units were recorded as containing supersaturated brines, the company said.
Anson said he plans to reenter the Mt Fuel-Skyline Geyser 1-25 well to test the thick Mississippian units and Pennsylvanian clastic horizons to confirm whether the supersaturated brines are lithium-rich. According to the company, the exploration program aims to target highly porous horizons, which result from the region’s geological structures. Porosity is confirmed by “seepages” observed in the drill program area.
At the Green River Lithium Project, the Clastic Zones and Mississippian units have no historical lithium and bromine assays recorded, but supersaturated brines have been intercepted during historical oil and gas drilling, Anson said. As a result, the Green River Lithium Project is classified as an exploration target. The exploration target for the Mississippian Leadville and Pennsylvanian Paradox units has a combined range of 2 billion tonnes to 2.6 billion tonnes of brine, grading 100-150 ppm Li and 2,000-3,000 ppm Br.
The exploration target is based on data generated from previous drilling programs for oil and gas, and drilling results from Anson’s exploration programs. It also uses parameters from the recent JORC resource in the Paradox project, such as lab-determined specific performance, Anson said.
According to Anson, only the existing drill pad needs to be reset, and this will result in minimal new ground disturbance to carry out the re-entry program. Using areas where there has already been land disturbance is part of Anson’s goal of developing a sustainable project and minimizing the project’s impact on the environment, he said.
