Under “MEMORANDUM” differences with the calls given in the location certificate may be explained, as well as typographical errors in the certificate. Because of corrections that may be required by the Bureau of Land Management it is well to prepare a preliminary draft of the notes for submitting to the BLM. The final typing, in triplicate, can be accomplished after all differences have been resolved. =5–11= The field notes and preliminary plat should be sent to the State Office of the Bureau of Land Management by either certified or registered mail with a return receipt requested. A copy of the preliminary plat may also be sent to the claimant with a copy of the letter of transmittal to the BLM. As a rule, the returns of mineral survey should remain confidential until the survey is approved. The mineral surveyor should maintain this confidence. If a demand is made of the Bureau of Land Management under the Freedom of Information Act, then the preliminary nature of the work should be clearly stated to the recipient. Processing the Survey =5–12= Preliminary Examination of Field Notes: The examination of the survey may begin by reading the notes and comparing them with the preliminary plat. As a general rule the mineral surveyor will write the notes from the plat. If inconsistencies appear, they will usually be typographical errors in the notes. However, this must be verified by the mineral surveyor. Particular attention should be given to the format as shown by the specimen notes of the Manual of Surveying Instructions, 1973. Corner descriptions must be proper and adequate. Ties should agree with the preliminary plat. Discovery points must be on public domain. By posting the mineral survey to the connecting sheet or similar plat with a pencil, conflicts and other surveys within 100 feet may be determined. The names of the locations must agree with those given in the location certificates. End lines must be parallel and the statutory length and width cannot be exceeded. Improvements should be fairly valued; the discovery point should agree with that given in the location certificate; common improvements should be correctly described and all claims benefiting therefrom should share equally. The geographic position of one corner of the survey must be given. Under “LOCATION” the correct section, township and range should be given. It should be stated that the survey is identical with the location as marked on the ground. If not identical, it should be so stated, and ties to location monuments must be given. The section corner tie may not exceed two miles from the nearest corner of the survey. Intersections with the lode lines and distances along the lode line to the discovery point must be given. (Exception: bedded deposits.) The bearing of the lode line, if different from the side lines, must be shown on the plat.
