Wyoming is home to several major mining
operations. The Project area has excellent road and rail infrastructure and is historically known to host rare earths…We have an alternative pool of technical experts, whose expertise will be beneficial as we also progress our La Paz Rare Earths project in Arizona.”
The Laramie Rare Earths Project was added to the WRE platform in late 2020 with the acquisition of this attractively priced emerging project that is conditional on the grant of Wyoming state mineral leases. The exclusive rights, purchased through ARR shares plus cash, came complete with data, samples, exploration permits, and maps.
As a sister project to the La Paz Rare Earths Project, the Laramie Rare Earths Project also comes with a great location northeast of Laramie, in a mining-friendly jurisdiction with world-class infrastructure. This includes being only 30km from the interstate freeway and 35km from rail lines, having access to abundant low-cost commercial electricity, and the ability to work in collaboration with multiple existing major mining operations and local engineering and construction companies.
Additionally, this project specifically benefits from a technical services team with more than 30 years of experience in rare-earth mining, including a rare earths expert geologist who is a Qualified Person in both the Australasian JORC 2012 code and Canada’s NI 43-101 classification scheme, a rarity outside of China.
Tested and Refined Processes
Initial studies have shown there is widespread surface REE mineralization over hundreds of meters, total rare-earth oxide (TREO) up to 0.60% in three initial sampling areas, and a high percentage of high-value Neodymium, Praseodymium, and Dysprosium.
As this Project occurs within the Laramie anorthosite complex – a proterozoic massif consisting of three anorthositic intrusions, three syenitic to monzonitic intrusions, and several smaller intrusions of leucogabbro and ferrodiorite – metallurgy is key to its processing potential. Rare earths occur at the Laramie prospect predominantly as the mineral Allanite hosted by clinopyroxene syenites that are part of a very large, differentiated Laramie anorthosite complex.
Allanite is coarse-grained (0.4mm to 2.5mm) as distinct mineral grains. DCM reported that “the large size of the allanite crystals should facilitate liberation upon grinding” from the syenite host rock. As such, mineral separation by magnetic (high REE content) as well as by gravity (very low REE content) methods have been tested, with 87% of the REE minerals being recovered into 27% of the mass and 76% of the REE minerals being recovered into 22% of the mass, respectively. In the case of magnetic methods, it was possible to reject 73% of the waste material at a crush size of -0.5mm, while it was possible to reject 78% of the waste material at a crush size of -2mm using gravity methods. Additional metallurgical tests are being conducted to optimize these processes even further.
