(b)
Offer for lease; deposits other than oil shale; questioned validity because of location; preference rights
If an offer for a lease under the provisions of this section for deposits other than oil shale is based upon a mineral location, the validity of which might be questioned because the claim was based on a placer location rather than on a lode location, or vice versa, the offeror shall have a preference right to a lease if the offer is filed not more than one year after September 2, 1960.
