MINING CORPORATION l'. o. Box 536 Grants Pass, Oregon, November 12, 1938. •r. Earl K. Nixon Director, Department of ueology and ~ineral Industries, 704 Lewis Building, Portland, Oregon. Dear Earl: :Mr. Brist9l showed us a letter he recently received from you in regard to his silica deposit near here. ne feel your interest in the matter is from an intimate knpwledge of the importanoe of this raw material to ourselves and to athers in the present planning f9r a manu:tacturing plant near ~onne- ville. · We note Ken Hamblen has discussed this deposit with 7ou and we wish to call your attention to the fact that his re­ port states the deposit was not discovered at the time of »r. Hodge's report and for that reason was not mentioned therein. ~o correct the records, I wish to inform you that I lgQked at this silica deposit ten or twelve ;years ago and have had it in mind ever sinoe; also when .Mr. Bristol left his hugo deposit I told him of the silica near Rogue River, which he afterwards 1ound adaptable. We have had a number of samples analyzed reoently and find the phosphorus content too ~igh for our purpose. ~he de­ termination made by :Mr. La.Zelle included in the .l:i8.lllblen report gives the correct phosphorus an\ hydride content, but seemingly is in error in reducing this return to phosphorus which he re­ ports less than half the correct figure. We are at present unable to find a satisfactory deposit ot silica within reasonable transportation distance of Portland and we are quite hopeful that your ~apartment may be able to assist us, therrefore please advise us if you hear of anltthing suitable for our needs.· ~he ore must have a very low phQBPhQrus content, prob­ ably a maximum of • 005~. With best wishes, we remain, Yours very sincerely, . •I RUSTLESS :MINING CORPORA.TI ON ' BFB:AH October 26, 1938 Mr.. lezm•th Hwtblen Luabel"al&Da Building Portland, Ontgoo Dear Mr. Ha.mbloru We are returning herew:L th a.nal.yaie report and aketchea waich you N> kindJ.,.v loaned ws.

STATE OF OREGON INTEROFFICE MEMO TO: Bristol Silica and Limestone Co. file DATE: November 6, 1986 Jackson County, Oregon Howard Brooks FROM: SUBJECT: Len Ramp, David White and I visited the property on October 17, 1986. We talked with Al Starkey and Vern Shephard. Starkey is mine manager. Shephard is a part of North Idaho Engineering and Development who was doing some exploration work on the dolomite deposit. Exploration plans included surveying, trenching, surface sampling, and compilation of a detailed topographic map from low altitude air photos. Drilling may be done later if warranted. Shephard told me the property is owned by Northwest Basic Industries (NBI). He is working for Ed Young who is a major (controlling?) stockholder of NBI. Young has tentative plans to operate the dolomite mine under an agreement with NBI. Starkey gave us a copy of a report entitled Micro-gravity survey of the Bristol silica and limestone deposit, Jackson County, Oregon by a group of professors and students from the Hawaii Institute of Geophysics, September, 1983. The report mostly theoretical geophysics - no geology - but concludes with the inference that the dolomite deposit extends "for several thousand feet horizontally and one thousand feet or more vertically." and calculated dolomite reserves are 10.5 million tons proven and 21.0 million tons probable.
