Dear Mr. Hansen,
Rio Algom Mining LLC (RAML) will be disturbing soil at its Lisbon facility property during a proposed
fall 2025 drilling program described in RAML’s August 26, 2025 letter to the Utah Division of Waste
Management and Radiation Control (DWMRC). According to condition 12 of RAML’s radioactive
materials license UT1900481:
“In order to ensure cultural resources are not disturbed in the future, prior to disturbing the soil
onsite, the Licensee shall conduct an archaeological and historical artifact survey of areas of its
property, not previously surveyed, including borrow areas to be used for reclamation cover. These
surveys shall be submitted to the Director for approval. The Licensee shall not disturb any property
included in the survey until the Licensee has received authorization from the Director to proceed.”
As indicated in RAML’s June 26, 2025 letter to DWMRC, RAML has completed cultural resource
surveys of its Lisbon facility property and submitted these surveys to the Utah State Historic
Preservation Office (SHPO).
A map of the proposed drilling locations, access roads, and support zones on RAML property is
included on Figure 1. RAML has verified that the proposed soil disturbance does not intersect any
identified cultural resources. A concurrent notification and a version of Figure 1 identifying cultural
resource information is being submitted to the SHPO under separate cover per Utah Code Section
63G-2-305(26).
RAML hereby requests the Director’s authorization to proceed with soil disturbance as required by
UT1900481 condition 12.
If you have any questions regarding this letter, please contact me at [phone].
Sincerely,
Rio Algom Mining LLC
