Analyses of 30 samples collected from Lovell Wash indicate that magnesium, strontium, and lithium contents of limestone increase as the borate beds are approached stratigraphically. Colemanite was discovered in White Basin in 1920 and mined until 1924. Two borate units occur in White Basin. The upper unit consists of up to 11 feet of colemanite, marl, and algal limestone. The lower unit is similar, but only 2 feet thick.
Associated marl is calcitic to dolomitic with montmorillonite and local celestite.
The colemanite is fine-grained to coarsely crystalline and generally occurs as nodules with radial internal structure. Locally, nodules are cut by colemanite veins up to 3 inches thick. Borate beds in White Basin dip gently, and the resource is generally closer to the surface than at the Anniversary mine. However, White Basin is cut by normal faults that segmented the borate into several different structural blocks, and much of the resource was subsequently removed by erosion. Although it is only half as thick, a composite White Basin section correlates well with the Lovell Wash section.
