In addition, an engineer-geologist was furnished to .Prepare. the diamond .drill ' core for analysis, coacpile the final assays. and lithologic descriptions, and ~ submit recommendations relative to the location of drill sites. ` Longyearprovided two hydraulic gasoline-powered rigs of its own ` design (see Plate III, Fig. 2). .The smaller unit, the Junior Straitline model,. which had been held over from the 195a work, is capable of drilling I to 1,200 feet. .The Model 4~ unit was deli fined for depths down to 3,000 feet. The Model 44 rig was equipped with awire-line core barrel which aided both [ core recovery. end drilling progress. ~ ~ Rock bits and drilling mud were used to-drill through the glacial overburden. When ledge (bedrock beneath the fluvial-glacial fill) was ~ i i encountered, casing was set, and a diamond core bit installed to core the ~ bedrock. Fresh water replaced the drilling. mud when coring operations began . .The rigs operated on a 24-hour-a -~Y, 7-~y-a-`+eek .drilling schedule. Three $-hour. work shifts Were used; each crew was-comprised oP a driller and a helper. Longyear provided one drill foremen to supervise the drilling ' ~ personnel and to oversee the maintenance of the rigs. ~ .Sample analysis -Core was subjected to a three-phase field analysis: .determination of magnetic polarity and.intensity, visual exams- nation, and measurement of s pacific gravity for estimation of magnetite content.

S. DAVIDSON ~ FROM: M. N. SLATER ,j ~ SUBJECT: KEMUK MOUNTAIN PROPERTY -` SOUTHIi~[ESTERN .ALASKA. ~~ DATE:: SEPTEMBER 27, 1977 1 At the request of Tom Harrow during our review on 8/3/77, I contacted ~ Edward T. Mi11er_and Richard A. Bray-who were. project geologists at Kemuk Mountain. I then located and obtained the report entitled "Kemuk Mountain iron ore prospect, Dillingham district; Alaska" by'W. J. Whaley and R. A. Bray. B. E. Kilpatrick has reviewed this report and his summary and recom- "~ mendations are attached. ? Bruce recommends no further work on this prospect because of the low grade ~ magnetite mineralization and the paucity of~base metal sulfide potential. ~ The core was scrutinized very carefully and any trace amounts. of copper mineralization noted were assayed for copper. The highest: copper assay was 'j 0.17% Cu. The core was not assayed for nickel; chromite or platinum group metals which characterize'well-layered cratoni.c mafic-ultramafic bodies and are common in alpine ultramafic complexes: The fact that the careful examina- ~ tion of the core revealed no significant sulfide accumulations suggests that ,,j little potential exists for the-above metals even if the sulfide type was misidentified. Several other magnetite rich, alpine ultramafic complexes ~ are known in southern Alaska and these ar.e also characterized 6y very .low ~~ base metal content. Finally Turam and AFMag surveys were conducted over th.e Kemuk Mountain property in an attempt to locate. sulfide concentrations. The ~ results of these surveys were negative but it should be pointed out that the thickness of the overburden (+200') probably rendered these techniques useless. The .attitude of the ultramafic complex remains `a point of conjecture but I ,~ tend to subscribe to Bruce's interpretation that the layering is steeply west dipping. This layering may be more apparent than real, however, because ~ the Kemuk complex is a Cretaceous alpine type and the-"layering" may be the result of tectonics and intrusive episodes rather than,. true magmatic layering characteristic of the large,.Precambrian, cratonic ultramafic complexes '~ (e.g. Bushveld complex,.Duluth gabbro, and Stillwater complex). '-~ The potential remaining at Kemuk Mountain is finding base metal sulfide accumula- ~ tions at the base of th.e ultramafic complex. We consider-this a long shot at best because of the low sulfide content drilled to date,: the .Cretaceous age .~ (rather than Precambrian), the alpine nature (rather than cratonic) and thee.

During the summer months of 19513 and 1959, fourteen of a total of seventeen core teats that ~rere drilled encountered the intrusive. .The intrusive is overlain by glacial -'~ fill material to depths varying Pram 9D feet to 4b0 feet. Magnetite was .discovered in percentages of 2 to 35 percent with the greatest concen- tration in a phase of the intrusive which is classified as magnetite "'~ pyro~aenite. The magnetite content averages 14.5 to 16.5 percent in the: ';~ western part of the. magnetite pyro~oenite mass, and 10.5 to 12 percent in the eastern. part. Traces of native capper, chslcopyrite, and sphalerite Were noted; however, extensive electromagnetic surveys completed in 1959 ;~ failed to detect anomalies which might suggest commercial deposits of . copper or other base sulfides. `~ Laboratory analyses indicated that the relatively low content of magnetite .j in the ore body ~rould require. high concentration ratios .that would preclude j ~ s commercially competitive mining operation at this time.. It is recommended, therefore, that Humble. conduct. no further exploration irk for its own ~~ acceunt in` the prospect area. There remains one untested possibility. of j ~ miegnetite enrichment, however, along the western margin of the intrusive. Since .several' iron~re mining firms have. expressed interest in the prospect, every effort should be made to retain the claims until it is learned i ) whether or'not the property can be farmed out for additional exploration. _~ ,:.:~ _~ ~,~ _.~ ~ iv j ~~ t GMC DATA REPORT ~ 5 5 Page 31 / ~. 8 9 I~ ~. ~> KIIyIUK MOUNTAIN IRON ORE.

Briefly, the Afmag instrument measures the plane of polarization of-the audio frequency caunponent of the earth's magnetic field. This varying-field is thought, o be generated by distant thunderstorms. These audio frequency components are normally polarized in a horizontal plane but are distorted in the presencx of a conductingt~ody, such as magnetite, graphite, abase sulfide, or a water course along a fault zone. By measuring .such distortions., the Afmsg is able to determine: the. position and size of the conducting body. The Afmag method is generally utilized in a reconnaissance survey. D The Turam unit measures a magnetic field created by passing as alternating current through a largehorizontal loop or a grounded cable. A small. portable. generator isemployed to produce the current. The magnetic field is distorted in the presence of a conducting body and components of this '" distortion are measured b the. Turam instrument. This method i a y s used in detailed survey, since readings moat be made at rather small intervals. In addition to this primary. function, Hunting provided aSharpe-A-2 magnetometer and a small Ronka direct-reading refraction seismograph unit for use where warranted. .

There is a possibility, however, that some of the measured samples :from the 1958 drilling may have been re ~sgnetized by' a i ' tits content. Zn addition J. D.

The data cannot, however, categorioally rule out the possibility of rl .richer ore at depth, or laterally. ~~~ Electromagnetics -Two Aug units, designed for rapid reconnais- s`~ sauce coverage, were employed at the beginning of the project.

Drill holes H-10 thru 5-16 Were located wholly, or in part, on the Turam anomalies. TWO grounded cable reconnaissance .surveys were extended beyond the Western and eastern margins of the claim block for a distance of Page 45/189 GMC DATA REPaRT 3 5 5 . l3 three miles. This xas done in an effort to locate a mineralized:contactzone betxeen the. intrusive and the country rock. No ano®alies were detected on these surveys. Refraction seismograph - As the drilling program developed, it became apparent that the boundssy of the intrusive could not be definitely este-bliahed by interpretation_of the. magnetic or electroumagnetic results. A .refraction seismograph survey was therefore attempted in the hope that, if distinct velocity contrasts existed between the intrusive~aad the surrounding country rocks, this method could detect them, and a determination of the .intrusive boundary could be made. Unfortunately, the small Ronka instrument Was designed for single layer, ahallox refraction work and xes not'suitabhe for the. multiple layer problems xhich rare encountered in the project area. .This approach xas therefore abandoned.

Economic Considerations ; } P.f ~~ Econa~ic Evaluation Economic evaluation of the Humbleprospect involves the following ~j ~'.> ` ~ considerations: 1 'i 1).; As abasis for comparison, the combined cost of .underground :`~~ ., mining .and beneficiation of Minnesota iron ore averaged $7.08: per ton in ; -1 1 `~' 1957, and the cost of open-pit mining and ore beneficiation averaged $3..68 : =~ per ton (Longyear Report, October 1959)• ~ the investigated intrusive lies - beneath 90 to 460 feet.ofoverburden, its mining probably `could be by under- ~1 "'I, . ground methods. Ore requiring a concentration ratio of 2 to 1 to produce~a - ~ , ~_~ marketable concentrate containing 65 percent iron trould cost $14.16 per ton of <~. concentrates at Minnesota's underground mining rates. Costs in Alaska, ~ however, could be up to 50 percent higher than those in Minnesota. Although involving higher capital autl.ey, handling of large tonnages by :intense .,~ ~d r mechanization could appreciably lasrer the mining and milling costs.' Through a mechanization program in the iron mines at Kiruna, S~reden, underground ' ~ mining is economical]y replacing open-pit mining. 2). The coat of transporting concentrates from the mill site to ~~ the market would be on the order of $2.2$ per ton to San Francisco and X4.05 ~' ' .~ ~ per ton to Tol~}ro (based upon data fYom Humble Traffic Department) . L 3). Theselling price of Bessemer-grade. concentrates (low phosphorous,; ~,~; content, 65 percent iron) is $t4.64 per ton at Lake Erie. 'A somewhat 1' higher price might be expected for similar concentrates from bugrers in the PaciYic Region. Concentrates from the investigated .prospect. would command -~ t would incur some b i t t a pr u , en ce premium for their lost.phosphorous con price. penalty for high titamium content. ~y '~ GMT ~a Page 64/ 89 TA REPORT 3 5 5 ~ a _. __ 2 5 In the light of the .above data, ore (roan the investigated prospect should contain at least 36 percentmagneticiron (require no .more than tiro tons of crude to produce one .ton of concentrates) to be mined. profitably at this time. As stated earlier, mineable thicknesses of magne- tite pyroxenite in.the western portion of the intrusive average 10.5 to ~) 12 percent magnetic. iron (require a 6.3-to-1 concentration ratio ),.but the magnetite: content of the intrusive appears to increase xestward. The ' magnetite enrichment ms~y not be sufficient to produce ore of 2-to-l concen- tration grade, but it could well produce an ore zone of 3- or ~+-to-1 .concentration grade along the entire western margin of the intrusive sheet. A long-term view of the iron ore economics of the Pacific Region. suggests that such an ore might be mineable at a profit at soma time in the Riture j (i.e. 20 years). The .western United States and Japan provides large and steadily increasing demandforiron ore. To meet this demand, deposits are being developed in Chile, Western Canada, and Southeastern Alaska (the Alaskan deposits are ultrabasic iratrusives that are strikingly similar to the investigated igneous complex, but they. are-well exposed sad located near tide~rater). The estimated .total reserves in iron. ore. deposits which .are tributary to the Pacific Region, however; are relatively low.
