Ann: Bulk Sample Collected at Big Sandy Lithium, page-13

There’s a big difference between going 100 feet deep:

For bulk sampling, a track-mounted boring auger would access the bulk sampling site and excavate the contents of three 3-foot-diameter holes to a not-to-exceed depth of 100 feet, which allows collection of 2,000-pound bulk sample within a single bulk bag. The 2,000-pound bulk bags would be palletized and transported via flatbed truck for transportation to off-site milling and classification. In total, boring and sampling would remove approximately 100–150 tons of material from the three bore holes at the bulk sampling site.

And drilling 360 feet deep:

Phase 3 drilling would focus on the sedimentary material host to the lithium mineralization. Phase 3 core holes would be approximately 3.5 inches in diameter, and the proposed coring depth would be a maximum of 360 feet (110 meters) using diesel-powered rotary coring equipment with fresh water and biodegradable polymer for coring.
