Diamond Creek Rare Earth Elements Overview

The Rare Earth Element (REE) bearing veins of the Diamond Creek area are on the short list of the well-recognized and studied occurrences in the United States. In 1979, M.H.Staatz, of the U.S. Geological Survey (USGS) estimated an overall probable resource at Diamond Creek of approximately 70,000+ tons of total rare-earth oxides, using an average grade of 1.22 percent. Reported sample assays show REE oxide contents ranging from 0.59 to 5.51 percent. Additionally, three samples cut across one of the larger veins were assayed for gold, and contained 0.5, 2.4 and 11.9 grams per tonne (0.017, 0.07, and 0.348 ounces per ton).

At Diamond Creek, the gold and REE’s occur within the same veins, but it is not clear if the gold is genetically related to the REE mineralization. Some of the mineral pulses have gold, thorium, uranium, niobium, yttrium and REE’s. Niobium and gold are possible by-products that would add greatly to the economics of the recognized deposits in Diamond Creek.

Our Land Package

The Diamond Creek REE Project covers approximately 1,841 hectares (4,550 acres) and is comprised of 244 unpatented lode mining claims in central Idaho, a first tier mining jurisdiction located just north-northwest of the town of Salmon, Idaho. The mineralization at Diamond Creek is found in quartz veins over a large area approximately 3.2 km (2 mi) long and 0.8 km (0.5 mi) wide. Idaho Strategic geologists have identified mineralization extending along strike beyond the historic USGS resource estimate of 70,000+ tons of TREO.
